摘要
为进一步选择伊犁州适生杨树无性系,采用随机区组试验,对8个杨树无性系1年生扦插苗进行苗高和地径的生长节律研究。结果表明:各无性系苗高和地径生长均为“S”形生长曲线,各无性系之间差异不显著;171、LX-1和TL-3的苗高年生长量均高于对照,分别为362.90、305.79和303.94 cm,较对照增加21.27%、2.19%和1.56%,TL-3和LX-1达到了显著水平,171达到了极显著水平;171、DX-08-8和TL-3的地径年生长量均高于对照,分别为2.26、1.93和1.92 cm,较对照增加36.90%、16.73%和16.33%,均达到极显著水平。无性系171和TL-3苗期在本地表现出较好的适应性,1年生苗年生长量均优于本地良种日本白杨。
In order to further select the suitable poplar clones in Yili Prefecture,a random block test was used to study the growth rhythm and ground diameter of one-year-old cuttings.Result shows that the seedling height&ground diameter growth curves of all clones are“S”type growth curves,and there is no significant difference between the clones;the annual growth of seedling height of 171,LX-1 and TL-3 is higher than the control,respectively 362.90,305.79&303.94 cm,an increase of 21.27%,2.19%and 1.56%over the control,TL-3 and LX-1 reach significant levels,171 reach extremely significant levels;the annual growth of ground diameter of 171,DX-08-8 and TL-3 is higher than that of the control,which is 2.26,1.93,and 1.92 cm respectively,which is an increase of 36.90%,16.73%,and 16.33%compared with the control,and all reach extremely significant levels.The clones(171&TL-3)show optimal adaptability at the seedling stage,and the annual growth of one-year-old seedlings isoptimal than that of local good-looking Japanese poplar.
