EFFECT OF PRE-SOWING TREATMENTS ON STONE GERMINATION AND SHOOT GROWTH OF MANGO (Mangifera indica L.) SEEDLINGS
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 52
Abstract
A trial was conducted to assess the effect of pre-sowing treatments on stone germination and shoot growth of mango seedlings. Mango stones were soaked for 12 and 24 hours in aqueous solutions of GA3 (100 and 200 ppm), Beejamruth (2% and 3%) and Thiourea (1% and 2%) and sown in polythene bags. Thiourea at 1% recorded the highest Seedling Vigour Index, shoot length, collar diameter and number of leaves. Soaking mango stones for 24 hours induced early germination, enhanced germination percentage, promoted vigour and increased shoot length, collar diameter and number of leaves. The minimum days taken for germination and the maximum germination percentage was observed in GA3 at 100 ppm. Evidence generated by this trial highlights the possibility of inducing early germination and producing vigorous rootstocks in mango by dipping stones in aqueous solutions of 100 ppm GA3 or 1% thiourea for 24 hours prior to sowing.
