摘　　要：通过对云杉、油松幼苗喷施不同浓度的赤霉素后,观察其生长变化情况并进行统计分析,结果表明,赤霉素对云杉生长量影响差异不显著,对油松地径生长影响差异不显著,对高生长影响差异极显著,最佳使用浓度对云杉苗高是150mg·kg-1,地径是10mg·kg-1。对油松苗高和地径的最佳浓度200mg·kg-1。Seedling-raising of spruce and Chinese pine were sprayed by gibberellin.The results showed that effect of applied gibberellin for spruce growth is no significance.Effect of Chinese pine seedling-raising base stock diameter is no significance.Effect of their height is the most significance.The best concentration for spruce stock height is 150mg·kg^(-1).Diameter is 10mg·kg^(-1).The Best concentration for Chinese pine stock height and diameter are 200mg·kg^(-1).
