| 摘 要： | 对11个供试的杨树无性系品种在5种不同的灌水量处理条件下,进行了连续3年的大田苗木生长对比试验,方差分析结果表明:5种灌水量处理对各个无性系品种地径、树高、枝茎干重影响极为显著;在相同灌水量处理条件下,部分无性系品种之间地径、树高、枝和干干重之间差异显著。根据上述试验结果,灌水量和枝和干干重作为选择指标,从中选育出灌水量少而干物质产量较高的J-4、J-3和J-1为优良品种,J-2、J-6、J-8为进一步选择的中试试验品种。 |
| 关 键 词： | 杨树无性系品种 灌水处理 方差分析 灌水量与枝茎干重比值 |

| Abstract: | Compared the growth of the diameter at foot,the height and the dry stem mass among 11 clones test under 5 kinds of irrigation treatments in the field,the results show: There are significant differences of them under the different irrigation treatments by variance analysis.There are also significant differences of the growth among the 11 clones under same irrigation treatment.In term of the results,taking irrigating amount and dry biomass of stem and branch as the chosen index,J-4,J-3 and J-1 are fine clones and J-2,J-6,J-8 are clones for further choosing. |
| Keywords: | poplars clones irrigation treatment variance analysis ratio of irrigating amount and dry biomass of stem and branch |
