Key words: Brassica napus , Canola, floral biology * Author for correspondence INTRODUCTION Among the plants with an economical importance, it is the family of the cruciferae, including about 350 kind and more than 4.000 species, with a great number of cultivated varieties as cabbage, cauliflower, brcoli, the kale and mustard among other potherbs Books. Chemistry. greenhouse. Observations were recorded on stages of flower bud development, However, cross pollination increases the number of seed setting. The anthesis stages were morphologically characterised and then related to stigma receptivity and pollen grain viability. The bees visited from 1-7 flowers/plant (x = 2.02; sd = 1.16), the time spent on the flowers varied between 1-43 seconds (x = 3.29; sd = 2.36) and, when seeking nectar and pollen, they invariably touched anthers and stigmas. phenology, pollination, mustard and fruit set, The first stage was pushed into second in 2-4 da. The ovary is superior and surmounted by a style with a two-lobed stigma. Carlos M. Herrera. The spatial separation of pollen presentation and receptive surfaces in a flower changed with time due to the continuing growth of the androecium and the gynoecium, and due to the temporal pattern of pollen presentation within the androecium. The bees' attendance to a small number of flowers/plants, their short permanence on flowers, their contact with anthers and stigma and the integral floral constancy allows their consideration as potential B. napus pollinators. The average length of stamens was 0.7 cm and 5 in number/flower. Floral formula of mustard (or) Cruciferae is Floral formula of Brassica campestris is. Pollen viability was 91.34 %. short-styled flowers do not set any fruits. Indian Council of Agricultural Research, Belavadi, V.V. 2008-2021 ResearchGate GmbH. Floral Diagram: It sometimes becomes very lucid if the ground plan of a flower be represented in the form of a floral diagram, in a floral diagram the position of the inflorescence axis or stem is shown by a dot or a small circle while the sepals, petals and stamens are put in concentric circles (or spirals when the floral phyllotaxy is spiral), the gynoecium being put at the centre. Stigma was receptive for longer duration (8 days from the day of anthesis) in CMS line which needs an external pollen source for fertilization to happen, whereas it was only 4 days in open-pollinated variety, assessed in terms of siliqua set and number of seeds/siliqua. Grinding and mixing the seeds with water, vinegar, or other liquids creates the yellow condiment known as prepared mustard. Some features of flower are as given below: Symmetry of flower On the basis of no. The leaves and swollen leaf stems of mustard plants are also used, as greens, or potherbs.

In safflower highest seed set (%) was obtained with stigma pollinated 24h after anthesis. The female part is the pistil, found at the very center of the flower. They are regular and cruciform, bisexual, complete, and hypogenous. A total of 19 insect visitors belonging to order Hymenoptera (15) and Diptera (4) were found to visit the mustard blossoms at Pantnagar. Pua, E.C. Similar observations were, Menzel, A. 1.

In Hymenopterans, the honeybees (Apis bees) were observed maximum followed by non Apis bees and the scolid wasp. Gaur, A (2007) Studies on stigma receptivity in Indian Floral formula of Brassicaceae (Mustard) is . All rights reserved. The minimum seed set (25.53%) was observed in case of controlled pollination by bagging. Reduced seed set can be explained by the fact that foreign pollen often caused stigma lobes to close together within 1.56 h, reducing subsequent receptivity. Considering bee food shortages during the winter season and that the canola is a winter crop, this study aimed to evaluate the foraging behaviour of Apis mellifera Linnaeus, 1758 regarding those flowers, and to verify if it presents adequate behaviour for successfully pollinating this crop in Rio Grande do Sul State. Cymose: Cotton, Jasmine, Brassica napus Linnaeus is considered a self-compatible crop; however, studies show that bee foraging elevates their seed production. BIOLOGY OF BRINJAL 1 1.

A single flower may remain open for approximately 3-7 days. Highest seed set was obtained by open pollination which gave 77.24 percent seed set followed by hand pollination (52.50 %). Further, chances of cross pollination are more in long style flowers. The ovary in such flowers is said to be superior, e.g., mustard, china rose and brinjal. Studies on stigma receptivity in Indian mustard. Brussels sprouts, (Brassica oleracea, variety gemmifera), form of cabbage, belonging to the mustard family Brassicaceae, widely grown in Europe and North America for its edible buds called sprouts.

Solanum tubersum (potato-white or Irish potato): It is an important plant in this family. The mustard family Brassicaceae, which includes the model plant Arabidopsis thaliana, exhibits morphological stasis and significant uniformity of floral plan.Nonetheless, there is untapped diversity in almost every aspect of floral morphology in the family that lends itself to comparative study, including organ number, shape, form, and color. The axis of the stem gets condensed, while the internodes lie near each other. Most commonly flowers yellow but occasionally white and about 1 inch in diameter. However, seed set was not reduced when pollen of both species was applied simultaneously to I. aggregata stigmas. Dr. Sudhakar Mishra. Therefore, this study was conducted late in the natural flowering period, but the pollinators were all taxa that naturally visit black mustard in our area. If anther dehiscence occurs before style elongates, the stigma pushes through mass of pollen, becomes coated with pollen and gets self fertilized. The pollen presentation time varied between 1.5 and 10 d. There were significant differences among species in duration of both female and male phases. 2). The peak flowering season for black mustard in our area is mid-June to early September. Flowers in the mustard family are all similar, and theyre a great way to identify a member of the mustard family. Woodfield, J.L. vulgaris.
