Seeds handbook: biology, production, processing, and storage. On the other hand, self-pollination ensures the perpetuation of the species when one partner is not nearby or promoters of cross-pollination agents are absent or scarce. The pollination restricted with tulle, in turn, did not differ significantly (p > 0.05) from hand selfpollination, indicating the importance of wind to transfer pollen between anthers and stigma in the same flower, in sesame, mainly because this treatment was also significantly superior (p < 0.05) to the other in which pollinators were prevented from visiting the flowers (pollination restricted with paper). [ Links ], HWANG, L. S. Sesame oil. Longitudinal sections of floral meristems during floral development. Data of seed weight and number of seeds per fruit were analyzed by analysis of variance followed by Tukey's test. Flower Structure of Sesamum - authorSTREAM Presentation. This study aimed to investigate the floral biology and pollination requirements of sesame (Sesamum indicum L.), cultivar CNPA G2. Beef Bread Bun Burger. The seeds were collected from the National Cereals Research Institute, Badeggi and were raised to maturity in pots filed To study the time of anthesis and flower longevity, 30 flower buds in pre-anthesis were tagged and randomly bagged with 20x20 cm nylon tulle bags 1 mm mesh. For the experiment on pollination requirements, we randomly selected 813 flower buds, which were divided into the following treatments: - T1: Free pollination - 140 sesame flowers were tagged with a ribbon in order to know the level of natural pollination of flowers by the activity of pollinators in the experiment site. FLORAL BIOLOGY Soybean belongs to family legumioseae and it is highly self pollinated. For the farmer in the crowd. Then the anthers dried up, changed color, darkened, and from white became yellow and brown. On the other hand, Free (1993) states that the stigma of sesame flowers only becomes receptive from two hours after flower opening. The study was carried out at Barbalha, State of Ceara, and consisted of two phases: floral biology and pollination requirements. Barcelona: Labor, 1970. [ Links ], VAISSIÈRE, B. E.; FREITAS, B.

The treatments of hand self-pollination, hand cross-pollination and free pollination yielded fruits with fewer seeds. 70 57 7. (Ed.). According to these results, wind pollination had no effect on the number or the weight of seeds per fruit. ; Current Opinion in Plant Biology 6 (JUN03) 215-222, fait le point sur les diverses enzymes nécessaires à la synthèse de l'amidon, notamment sur les données récentes sur l'ADP-glucose pyrophosphorylase (AGP), l'amidon synthase (SS), les enzymes ramifiantes (BE) et déramifiantes(DBE). The observations showed that the ovary is superior and green, and the style is filiform, ending in a bifid stigma. Finally, the free pollination resulted in the best fruit setting rate, which was significantly different (p < 0.05) from all other treatments, indicating that the visit by biotic pollinators is important for sesame pollination, whether increasing the efficiency of pollen transfer within the same flower or even bringing pollen from other flowers, providing cross-pollination, which was also able to set fruit in sesame (Table 2). The main producing countries are Egypt, Central Africa, Israel, Peru, Saudi Arabia and Macedonia. 249 The seed is highly valued as a source of oil, as well as for its antioxidant lignans. Florianópolis: UFSC, 1986. Floral Biology and pollination requirements of sesame (Sesamum indicum L.) A comparison of two pollinators: the introduced honey bee (Apis mellifera) and a indigenous bee (Centris tarsata) on cashew (Anacardium occidentale L.) in its native range of NE Brazil. The androecium consists of four stamens, two long (1.5-2.0 mm) and two short (1.0-1.5 mm) and the gynoecium has superior ovary, multicarpelar and a long style (1.5 - 2.0 mm) with bifid stigma. Accepted on November 19, 2013. Foi demonstrado que o gergelim é uma planta de polinização mista, pois pode produzir frutos sob qualquer um dos tipos de polinização testados. Time of anthesis and duration of flowers were recorded. SlideShare Explore Search You. 6th ed. Flowers were observed as for time of anthesis, lifespan and stigma receptivity, and were applied the following pollination treatments: open pollination, hand cross-pollination, hand self-pollination, pollination restricted with tulle bags and pollination restricted with paper bags. 69 111 8. New York: Marcel Dekker, 2004. With regard to the pollination requirements of sesame, there is no consensus on the predominant type of pollination. Elle traite de leurs isoformes et des régulations de ces enzymes. For the same reason, the treatment of open-pollination, which promotes cross-pollination, was also superior to others and was not different from that of hand crosspollination (Table 2). 6 avis clients. The fruit is dehiscent, and the dehiscence starts at the apex toward the base. 321 Free images of Sesame. Floral biology and breeding techniques . The keel petals encloses the pistal and the stamen. Le sésame est une plante oléagineuse dont on consomme la graine. [ Links ]. - T4: Hand self-pollination (geitonogamy) - a day before the work of pollination, 185 flower buds that would open the next day were bagged with tulle bag and were protected from any possible pollinator. Une seule capsule de la plante peut renfermer 200 graines. 50 39 9. When the corolla of the flower falls, the style remains in the flower until the end of the day, falling in late afternoon, including in those that were hand pollinated and later generated fruits. (Rubiaceae). Cambridge: Cambridge University Press, 1989. Studies on floral biology in sesame Data provider: Information Systems Division, National Agricultural Library. In this experiment, the number of seeds produced per fruit in sesame indicated that the pollination requirements of sesame flower were met. ABSTRACT Pollen production, viability and germinability were assessed in three sesame cultivars viz Kenana4, Ex-Sudan and E8. The field is broad and interdisciplinary and involves research requiring expertise from multiple disciplines that can include botany, ethology, biochemistry, entomology and a range of analytical techniques. 3rd ed. Presently, sesame is explored in 65 countries across Asia, Africa, Europe and Central and South America. Sesame is a mixed pollination plant, able to selfpollinate and reach levels above 50% fruit set, but with potential for significant increase in fruit production in the presence of biotic pollinators that promote cross-pollination. Data on fruit harvest showed different results of the initial fruit set. The last pollination was held at 10h, showing the lowest number of fruit set and significantly different (p < 0.05) from the time of 8h. The highest fruit set per plant due to crosspollination by biotic pollinators produces fewer and lighter seeds per fruit, but a greater yield per plant. Issues in new crops and new uses. 70 83 13.

Floral biology of sesame The flowering period was from November to December, starting the ripening of fruit after 60 days of flowering. Floral biology is an area of ecological research that studies the evolutionary factors that have moulded the structures, behaviour and physiological aspects involved in the flowering of plants. In: WEISS, E. A. Then there was a drop at 9h, which was even more pronounced at 10h, although these two times were not significantly different to each other. Unlike other varieties of sesame which have one or two flowers per leaf axil, the CNPA G2 variety has three flowers. In this treatment we sought to estimate the effect of wind on pollination in sesame, bagging 174 buds. [ Links ] FAEGRI, K.; VAN DER PIJL, L. The principles of pollination ecology. Introduction Sesame (Sesamum indicum Linnaeus) is an important oilseed crop grown since the beginning India ranks first in area, production and export of sesame in the world. B.

Before hand-pollination, the flowers were emasculated with the aid of fine tweezers, while their stamens were not releasing pollen. Anthers are yellowish and 1 mm in length. Boca Raton: CRC Press, 2007. v. 4, p. 231-289. Probably, these treatments had greater deposition of pollen directly on the stigma, enough to fertilize all the ovules present in the ovary. (C, D) anther wall layers formation. Sesame was introduced in Brazil by the Portuguese in the XVI century from their Indian colonies (ELLEUCH et al., 2007; KOCA et al., 2007; WIESS, 1983). They occur singly or in groups of two to three in the leaf axils and are hermaphrodite. Cela … Significant differences (p < 0.05) were detected between treatments for the number of fruits harvested 30 days after pollination.

The significantly higher (p < 0.05) fruit yield as a function of the cross-pollination in relation to selfpollination contradicts Weiss (1983), who stated that sesame is a predominantly autogamous species, which could only and possibly present allogamy above 10%. Despite showing the lowest rate of fruit set and differ significantly (p <0.05) from all other treatments, the pollination restricted with paper set fruits suggesting that sesame accomplish autopollination. Pollinations restricted with paper and tulle bags produced fruit with greater number of heavier seeds. Nevertheless, sesame seems to have evolved to favor self-pollination, but also developed mechanisms to attract biotic pollinators, such as differently flower, showy color, odor and nectar secretion, in order to promote some percentage of cross-pollination (FAEGRI; VAN DER PIJL, 1979). Le miel (prononcé en français : /mjɛl/ [1]) est une substance sucrée élaborée par les abeilles à miel à partir de nectar [2], [3], [4] ou de miellat [5], [6].Elles l'entreposent dans la ruche et s'en nourrissent tout au long de l'année, en particulier lors de périodes climatiques défavorables. In nature, self-pollination is less advantageous because it does not favor new genetic combinations and thus the production of more vigorous seeds and plants, so that some plant species have mechanisms to prevent the occurrence of self-pollination (CONSOLARO, 2005; RAVEN et al., 2007). (Ed.). Got it! The predominant climate in the region is Aw'i (humid tropical climate), according to the Köppen classification, and the average annual temperature is 24ºC and mean annual rainfall of 1,200 mm, with the rainy season from December to May.

The effect of salt stress on lipid peroxidation, antioxidative enzymes and proline content of sesame cultivars. Menu. The best performance of crosspollination is probably due to exchange of genetic material promoted by this type of pollination, increasing the heterozygosity of the embryo formed in the seeds, which according to Mahfouz et al. Keywords: self-pollination, cross pollination, pollinators, fruit. B. This is the post excerpt. The current world production is estimated at 7,725,706 tons, with yield of 390 kg ha-1, being the ninth most cultivated oilseed crop in the world. The androceum is didynamous with four stamens, in pairs, one lower than the other, epipetalous, fused at the base of the upper lip of the corolla tube, and anthers with rimosa or longitudinal dehiscence. Two hours before anthesis, the four filaments of stamens elongated rapidly, so that at the time of anthesis (6:30 to 7h), anthers of longer stamens reached the stigma height, while those of shorter stamens were positioned just below the stigma.

The bags remained in flowers for 3 days, preventing any contact with biotic and abiotic pollinators. (2002) for the cashew (Anacardium occidentale). The observations concerning floral morphology, color of petals, stamen number and anther characteristics were performed on 30 randomly tagged flowers, while flower buds were monitored every hour from the time of anthesis until they fall from the plant. Voir les autres cadeaux. This indicates that possibly autogamy resulted in an advantage to the plant's reproductive success. Around 11h, the flowers began to show signs of senescence, mainly by withering of anthers and drying of the stigma. The results of fruits harvested show that sesame is a plant with mixed pollination, which produce fruit by both autogamy (auto and self-pollination) and crossbreeding (cross-pollination), like most higher plants (DELAPLANE et al., 2013). Palavras-chaves: autopolinização, polinização cruzada, polinizadores, frutos. O trabalho objetivou investigar a biologia floral e as exigências de polinização do gergelim (Sesamum indicum L.), cultivar CNPA G2. The calyx has five fused sepals. Sesame (S. indicum), in addition to coconut, is one of the two oldest oilseed plants used by humanity, 248 with records dating back to about 6000 years. Nevertheless, crossing rates reported in some studies ranged from only 1 to 68% (ABDEL ALL et al., 1976; ASHIRI, 2007; FREE, 1993; SARKER, 2004; YERMANOS, 1980), evidencing the need for further clarifications in this regard. Cercetari Agronomice in Maldova, v. 46, n. 3, p. 155. 125 164 38. Cream Milk Cream Sugar. At this stage, while the flower was developing, the anthers of the longer stamens were located below the height of the stigma, but still closed, while those of the shorter stamens, in turn, were located well below the anthers of the longer stamens. 182 215 34. The country is a small producer with only 6,000 tons of grain produced per year on 9,000 ha and a yield of around 640 kg ha-1 (FAO, 2012). Thus, sesame pollination can occur at any time from anthesis to 10h, but is most effective between 7 and 9h. Anthesis occurs early in the morning when the stigma becomes receptive and senescence can occur six to 12 hours later, depending on the variety and environmental conditions (FREE, 1993). Around 12h, the stigma had become dry and withered, lobes were closed again. Sesame can be very beneficial to rotate in a cropping system. Asia and Africa hold about 90% of the planted area (BELTRÃO; VIEIRA, 2001). Rio de Janeiro: Guanabara Koogan S.A., 2007. Probably, these variations are due to factors related to the differences in sesame cultivars, temperature, and/or relative humidity and luminosity at different hours of the day, among the sites studied. B. The National Agricultural Library is one of four national libraries of the United States, with locations in Beltsville, Maryland and Washington, D.C. (Ed.). .

The number of fruit set, five days after anthesis of flowers, and harvested showed significant differences (p < 0.05) between treatments of pollination in Barbalha, State of Ceará (Table 2). 81 65 14. Combien de temps vous reste-t-il ? At the end of December, the flowering decreased, ceasing completely in January. 2011. The flowering period was from November to December, starting the ripening of fruit after 60 days of flowering. A higher number of seeds per fruit is a desirable feature for sesame both from the commercial and ecological point of view, being an important indicator of plant reproductive success, since a greater number of seeds produced will increase the chances of perpetuation of species (ROUBIK, 1989). [ Links ], FONT QUER, P. Dicionário de Botânica. The flowering period was from November to December, starting the ripening of fruit after 60 days of flowering.

It is believed that sesame is one of the oldest crops in the world, cultivated for over 4,300 years in Babylon and Assyria (HWANG, 2005). For this, 120 flower buds were bagged and tagged and, in the next day, from 7h, when the flowers were already open and the stamens had released pollen, 30 flowers were debagged, hand-pollinated with pollen from flowers of another plant and bagged again. (1976) have suggested that it is receptive before flower opening, remaining viable for 24 hours after anthesis. 76 23 71. Received on September 7, 2013. The pollination restricted with tulle showed a significant difference (p < 0.05) between the hand self-pollination and hand cross-pollination, but pollinations restricted with tulle and paper were not significantly different (Table 3).

This result indicates that despite the hand self-pollination increased initial fruit set, it does not necessarily mean that the flower has been fertilized and the fruit can be aborted in its early stage of development, as registered by Holanda Neto et al. Contd… The corolla begins to emerge from the sepals. Oxford: Pergamon Press, 1979. Due to the lack of information on the pollination of sesame in the literature and its contradictions, the present study was conducted to study the floral biology and determine its requirements for pollination in the state of Ceará. The flowers are complete, gamopetalous, zygomorphic and with a short stalk. Donner mon avis. Watch Queue Queue Sesame: Sesamum indicum (Pedaliaceae) Sesame (Sesamum indicum) is native to the Old Word tropics and is one of the oldest cultivated plants in the world.Sesame oil is not mentioned in the Bible, but appears to have been important in non-Hebrew cultures 2,000 to 4,000 years ago. At 7h, when the flower opens, the rate of fruit set was 73.33%, not different (p > 0.05) from 8 hours, which was 85%, with the highest percentage of fruit set when compared to other times (7, 9 and 10h), suggesting a peak of receptivity, and therefore of fruit set at that time. Houve diferença significativa (p < 0,05) entre os tratamentos no número de frutos colhidos 30 dias após as polinizações. 4.9/5. This evidence becomes stronger because the manual self-pollination presented the second best rate of initial fruit set, implying the existence of a strong autogamy in this species.

Unlike other varieties of sesame which have one or two flowers per leaf axil, the CNPA G2 variety has three flowers. Alexandria: ASHS Press, 2007. p. 144-182. These features are apparently common to many varieties of sesame, considering the similarity with that observed in other varieties by several authors (FONT QUER, 1970; PRATA, 1969; YERMANOS, 1980). After 10h, pollen grains were no longer observed with the naked eye and stigmas had withered up. Hybridization of crop plants. Geobros (Jodhpur), v. 31, n. 1, p. 49-51, 2004. ".

[ Links ], ROUBIK, D. W. Ecology and natural history of tropical bees. The next day, at the moment of highest receptivity of stigmas (determined as described above), we removed the bag from each flower and then took the anthers of some flowers on the same plant and touched the stigma of the flower to be pollinated. According to Wiess (1983), this species is predominantly autogamous. Steph Charman Named Business Leader: Specialist Distribution At British Specialist Lending Awards 2020 . Cadeaux du mois. SESAME est à l'origine et depuis 1998 un magasin de produits diététiques et de cosmétiques bio. Its cultivation has great economic potential, because of great demand, both nationally and internationally. As for the data concerning the weight and number of seeds per fruit, significant differences (p < 0.05) were observed in the number and average weight of seeds per fruit between the different treatments. Donut Sweets Baking. At the end of December, the flowering decreased, ceasing completely in January. This variation in floral biology was probably due to different environmental conditions observed by these different authors in different locations and/or the variety studied is formed from crossing different varieties, producing a cultivar with high genetic variability. The results suggest that the type of pollination affect the weight and number of seeds per fruit. Marie-Josée. After the flower fall the tulle bag was removed. Additionally, the treatments were compared one by one, at the 5% significance level. For this, we used the software SAS, FREQ procedure, because the data had binomial character (fruit set = 1 X fruit not set = 0), thus not meeting the assumptions for analysis of variance. Keywords: Biology, sesame, Antigastra catalaunalis, Leaf webber and capsule borer 1. Langham (2007) described the development of sesame in 11 countries over 40 years and concluded that different genotypes can develop very differently under the same conditions.
