GENERAL DESCRIPTION Brinjal or eggplant (Solanum melongena L.) is an important solanaceous crop of sub-tropics and tropics.The name brinjal is popular in Indian subcontinents and is derived from Arabic and Sanskrit whereas Substantial effect of sowing date on stigma receptivity was observed; it was longer in plants sown during October in comparison to those of November in both years. 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. They appear in button-like clusters and have four petals and six stamens, four long and two short. November. 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.” Brussels sprouts may have been grown in Belgium as early as 1200, but the first recorded 67 0 obj The anthesis stages were morphologically characterised and then related to stigma receptivity and pollen grain viability. Cambridge University Press, New York. Physics. A single flower may remain open for approximately 3-7 days. The ovary is superior and surmounted by a style with a two-lobed stigma.

Insect pollination manual. Foreign pollen precedence decreased mean seed set by almost 50%, which is consistent with effects observed in previous experiments. 10) The people of Ireland completely depend on potato for food. of Hymenopterans were maximum followed by the Dipterans and others. 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. Castor Ricinus communis (2n=20) Euphorbiaceae. 10) You can remember that the stamens are the male part of the flower because they always "stay men". Biotechnology in Agriculture and Forestry, Spronger. In medium styled flowers, fruit set ranges from 12.5% to 55.6%. Mustard seed is used as a spice. In Hymenopterans, the honeybees (Apis bees) were observed maximum followed by non Apis bees and the scolid wasp. If anther dehiscence occurs after style elongates, stigma passes through the anther tube without becoming pollen coated, then cross, Join ResearchGate to discover and stay up-to-date with the latest research from leading experts in, Access scientific knowledge from anywhere. The name crucifer is derived from the shape of the flowers that have four diagonally opposed petals in the form of a cross. Further, chances of cross pollination are more in long style flowers. The performance of the honeybee as pollinator depends on several factors, namely the availability of pollen and nectar in flowers, weather and physical aspects of soil. Hand pollination decreased the duration of stigmatic receptivity and pollen presentation significantly. The ovary in such flowers is said to be superior, e.g., mustard, china rose and brinjal. and Ganeshaiah, K.N. and Hill, G.D.

ResearchGate has not been able to resolve any citations for this publication. Stigma remains receptive up to 32-56 hours after anthesis. (ii) Flower is a modified shoot: The shoot apical meristem changes to floral meristem. The pollen load presented 100% of B. napus pollen. Solanum tubersum (potato-white or Irish potato): It is an important plant in this family. Highest seed set was obtained by open pollination which gave 77.24 percent seed set followed by hand pollination (52.50 %). The average length of sepal was 0.53 cm and that of petal 0.74 cm.
