编织柳杂种新无性系生长比较1）

摘要

采用随机区组设计试验，经过早期选择，对进入新种质备选材料库的7 个编织柳新杂种无性系进行了生长性状比较。结果表明：各参试无性系生长进程呈S 型曲线，可以用Logistic 函数拟合，在南京地区最快生长期为5—8 月中旬；方差分析表明，新无性系JW4－5、JW0－5 的高生长显著优于其它无性系，平均高生长量分别达150、157 cm，可以作为进一步开展区域试验的新品种。%By randomized block design, we tested the growth process of seven new clones as new germplasm material stock.All the tested clones’ s growing process were in an s-shaped curve, can be fitted by using Logistic function.The fastest grow period in Nanjing area was in the mid-May to mid-August.By the analysis of variance, new clones of JW4-5 and JW0-5 was significantly better than the others in height growth, with the top average height of 150 cm and 157 cm, respectively, and can be used as a further variety regional test.
