Abstract

Investigations on the ,effects of growth substances (GA, IAA and IBA) and boric acid on grape pollen have shown that maximum germination and tube growth was obtained rwith boric acid at lower concentrations (5, 10 and 20 ppm) as compared to GA, IAA, IBA and control. Although GA showed lesser pollen germination, pollen tube growth was enhanced at 5, 10 and 20 ppm in the grape cultivars under study.
Pollen grains of Pusa Seedless were stored for 12 months and Pearl of Csaba for four months at different combinations of temperature and ihumidity. The pollen viability was highest when sfored at -12° to -10° C with 25 per cent R.H. which was followed by 4° to 8° C ,and 25 per cent R.H. The pollen germination increased throughout the storage period by boric acid at 5, 10 and 20 ppm.
