Abstract

Balanites roxburghii fruits are potential alternative source of diosgenin oil and protein. Fruit developmental morphology has been investigated by measuring the rate of growth and studying the internal structure at different perjods of time. Three distinct growth phases were distinguishable. The cause for curvature of young,fruits was found due to the displacement of the four aborted ovules by the developing fertilised ovule. Spray treatment with Gibberelic Acid 200 ppm was found effective in controlling early fruit drop which was heavy.

Abstract

Vegetative propagation methods were tried in Balanites roxburghii every month during 1983-85. Even with external hormonal treatments of Indole Butryic Acid. Napthalene Acetic Acid and Seradix powder. Stem cuttings failed to ischolar_main. But success has been achieved by adoption of ringing technique done during monsonn perind, with Seradix powder application on the, twigs covered with wet moss.

Abstract

The information of age at which the plant starts flowering hitherto lacking, is now known. Although flowering is twice in a year, fruits generally are available only once annually during winter. Irregular bearing is observed in some trees. Heredity and vigour are perhaps the factors affecting the bearing. Fruits borne on older and thicker branches usually attain maturity, while premature fruit drop occurs on comparatively younger and thinner branches. Heavy fruit drop has been observed. Both fruit pulp and seed are often infected by two different moth pests.
