Chhabra Floral Biology Floral Biology of Castor Ricinus communis Slide 2: CASTOR © A.K. Chhabra Floral Biology The castor plant is normally monoecious with about 50-70% male flowers occurring towards the base of a racemose inflorescence and 30-50% pistillate flowers in the upper portion The Plant Slide 3: Students visiting crop of Castor Slide 4: Field View of Castor Slide 5: CASTOR © A.K. Chhabra Floral Biology The Plant Close-up The castor plant is normally monoecious with about 50-70% male flowers occurring towards the base of a racemose inflorescence and 30-50% pistillate flowers in the upper portion inflorescence Slide 6: CASTOR © A.K. Chhabra Floral Biology The spike consists of unisexual flowers. The lower portion of raceme bears male flowers, the upper female. The ratio between them being a varietal characteristic but is also strongly influenced by climate. High temperature favours maleness as does plant age and short day length, the reverse favours femaleness Female flowers The Inflorescence Male flowers Slide 7: CASTOR © A.K.

Chhabra Floral Biology Mature Seed (Before Harvest) Ricinus communis “Ricinus” is a Latin tern meaning “dog tick” because of the resemblance of castor seed and a tick found on dog. Apart from oil contained in the seed its protein is used to produce distempers, oil bound water paints, adhesive for wood and products similar to casein proteins Slide 32: CASTOR © A.K.
