Chhabra Field View Groundnuts are also known as goobers, Peanuts, and pincers Slide 4: © A.K. Chhabra Field View Groundnuts are also known as goobers, Peanuts, and pincers Slide 5: Close-up view of crop © A.K. Chhabra Slide 6: © A.K. Chhabra Uprooted plant with pods Slide 7: Close-up of uprooted pods Slide 8: Flowers are born in the axil of leaf Axil of leaf Plant without roots The first flowers appear near the base of each branch, 4 to 6 weeks after planting. Slide 9: The peanut flower is yellowish and about one-half inch in size. There may be one to several flowers in an inflorescence on the plant, but only one opens on one day, and there is an interval of one to several days between the opening of successive flowers Flower Slide 10: Flower Slide 11: Peanut flower has a recurved beaked keel, with two petals fused along the dorsal edges to the apex but open ventrally at the base. Flower Slide 12: Keels Reproductive organs Gynoecium and androecium taken out of keels Slide 13: There is a club-shaped stigma on a tortuous style extending beyond the eight functional and two sterile stamens Slide 14: There is a club-shaped stigma on a tortuous style extending beyond the eight functional and two sterile stamens Close-up Anthers Slide 15: Calyx Corolla Slide 16: © A.K. Chhabra Calyx The calyx has five lobes; in two groups of one and four. They form a narrow sparsely pubescent hypanthium 1 sepal 4 sepals Slide 17: Calyx & Corolla (standard) Calyx Standard Slide 18: Calyx & Corolla Calyx Standard Wings Slide 19: There is a club-shaped stigma on a tortuous style extending beyond the eight functional and two sterile stamens Close-up Slide 20: Parts of corolla Standard Wings Keels There is one standard (largest), two wings (free) and two keels (fused) enclosing reproductive organs. These 5 petals have been separated and shown in this picture. Slide 21: Aerial Portion Under ground Peg After pollination, the flower fades and the ovary elongates to become the peg, which pushes into the soil Slide 22: Pod formation Peg In 7 to 10 weeks, the peg matures into the reticulated pod of one to five edible seeds separated by slight constrictions Slide 23: © A.K. Chhabra Pods of groundnut being uprooted from the soil Pods Pegs Slide 24: © A.K. Chhabra Bunch of pods borne on a plant Slide 25: Reproductive Organs Staminal column Oblong anthers (4) Globular anthers (4) Stigma Non-functional anthers (2) Slide 26: Staminal column Oblong anthers (4) Stigma Non-functional anthers (2) Reproductive Organs Another View Keel Globular anthers (4) Slide 27: Staminal column Oblong anthers (4) Stigma Non-functional anthers (2) Globular anthers (4) Reproductive Organs Another View Slide 28: Pod at physiological maturity Groundnut Slide 29: Mature pods and seeds Slide 30: The End You do not have the permission to view this presentation.
