摘要/Abstract

摘要： 在昆明树木园开展了须弥红豆杉幼苗的露地栽培试验,通过连续观测及数据收集,分析了该试验点须弥红豆杉幼苗的各项生长指标的变化情况,结果表明:1)当年的8—9月是须弥红豆杉幼苗高生长的最佳时期。2)幼苗侧向生长旺盛。3)幼苗的高径生长特征之间存在极显著的正相关性;最大分枝长与地径之间存在明显的正相关性。4)有少量的偏冠现象。

Abstract: The Kunming Arboretum was selected for the field experiment of the seedlings of Taxus wallichiana,which were cultured in the open.With the continual observation and data collection,changes of morphological indexes of the seedlings were compared and analyzed. The results are as follows:1)the optimum period of the seedlings' height growth was August to September; 2)The lateral expansion of the seedlings was prosperous;3)There was the most significant positive correlation between height and diameter of the seedlings and there was a significant positive correlation between the branch length and the diameter;4)The excentric crown phenomenon of the seedlings was slight.

Key words: Taxus wallichiana, seedling, morphological character, Kunming arboretum
