The Grow Dynamics of Cultivars of Sea Buckthorn in Seedling Period
Abstract
The grow dynamics in seedling period of 7 sea buckthorn varieties were studied. The results showed that the seedling height and number of leaves early growth were faster than the latter part of the growth in 7 sea buckthorn varieties. The maximum growth of seedling height and numbers of leaves in15days was QiQieke,and followed by ZhuangYuanhuang. The lowest growth of numbers of leaves in15days was Qiuyisike. The height growth process of 7 sea buckthorn seedlings was divided into four stages with the sequential sample cluster analysis,taking the height net growth increment of 7 sea buckthorn seedlings as samples: emergence stage,early growth stage, rapid growth stage and late growth stage,and height growth was maximum in rapid growth stage,followed by early growth stage,the lowest growth at emergence stage and late growth stage.
