The present study was carried out in laboratory at Faculty of Forestry Sher e-Kashmir University of Agriculture Science and Technology of Kashmir, Benhama, Ganderbal, Jammu and Kashmir during 2011-2012 to investigate the effect of different GA3 concentrations viz. 50, 100, 150, 200 and 250 ppm on germinabiliy and growth of seeds Picea smithiana under laboratory and nursery conditions imbibed for 0, 24 and 48 hours durations. From this study it was found that the seeds treated with 200 ppm GA3 for 48 hours produced better germinability and growth both under laboratory and nursery conditions. The maximum germination percentage under laboratory recorded was 70.62 % with the germination capacity of 80.75 %, germination energy of 48.99, germination speed of 28.52 and germination value of 5.90.Whereas the maximum germinability viz., germination percentage, germination, germination value and plant percent of 64.00, 34.21, 2.82 and 54.50 respectively. The germination results indicated that Picea smithiana seeds do possess inherent dormancy which increases with storage. Therefore it is advised that spruce seeds should be imbibed in 200 ppm GA3 for 48 hours for better germination and growth.
