| dc.description.abstract | The wild ber (Zizyphus rotundifolia) belonging to family Rhamnaceae is wildly grown in arid and semi –arid region of India. It is hardly, drought resistant and suitable for preparing root stock. In Chotanagpur plateau region, wild ber is cultivated in large area both for its fruit as well as for lac cultivation. The problem associated with ber cultivation is not poor production but its quality. Ber tree grown in this region are mostly seedling tree which bear heavy crop of inferior quality. The area under improved ber is restricted due to unavailability of the genuine planting material. Seeds of ber have poor germination capacity and plant take more time to attain the suitable size of budding. Germination has been found to be promoted by soaking the extracted seeds in growth regulators as well as in chemical solutions, Foliar application of growth regulators was also found to exert influence on getting buddable size stock at early period. The present investigation on the effect of growth regulators on seed germination and seedling growth of wild ber was carried out in the Department of Horticulture, Birsa Agriculture University, Ranchi during the year 1996.The experiment was laid out in complete randomized design(CRD) replicated three times. Highest germination of 86.66 per cent was observed in seed soaked in 500 ppm gibberellic acid for 24 hours and lowest germination of 42.78 percent was in control. The maximum plant height ,girth,length of internode, number nodes, fresh weight, dry weight and root length of ber seedlings were observed in treatment having seed soaked in 250 ppm Gibberellic acid and raised seedling sprayed with GA# 50 ppm twice and minimum in treatment which seedlings raised from dry seeds and seedling sprayed with Maleic hydrazide 50 ppm twice. Thus, it can be concluded that for getting proper sized root stock of wild ber, the seeds may be dipped for 24 hours in Gibberellic acid (250ppm) and the seedling should be sprayed with GA3 (50ppm) twice. | |
