Abstract

Present investigation was carried out during the winter season at Horticulture Research block, Department of Horticulture, Shri Guru Ram Rai University, Dehradun, Uttarakhand. To investigate the effect of GA3 treatment on growth attributes and days taken for germination initiation of walnut. The experiment was laid out in randomized block design with three replications and twelve treatments. The treatments comprised following levels of GA3 concentrations viz. 500ppm, 1000ppm, 15000ppm and control in three different replications of Horticultural Research Block. Various observations regarding growth parameters such as leaf length, leaf width, shoot length, shoot width and numbers of days taken for germination initiation of walnut were recorded. The result revealed that treatment of GA3 1500ppm of nursery polybag application found to be beneficial for vegetative characters viz, found to be the most effective treatment for increasing leaf length, shoot length and shoot diameter. In another point of view, 1500ppm GA3 treatment in polyhouse was found to be profitable as compared to rest of treatments in terms of number of days taken for germination. Apart from this leaf width of 1000ppm in nursery polybag was found best.
