| 摘 要： | 比较了5个腰果无性系株形之间的差异,分析了各株形性状之间及其与产量性状之间的相关性。结果表明：5个无性系之间的主干高度、主干直径、2级枝梢长度、3级枝梢直径、4级枝梢长度、4级枝梢直径均存在显著差异,1级枝梢长度、1级枝梢直径、2级枝梢直径以及3级枝梢长度之间的差异均不显著;5个无性系之间的结果枝叶片数量、叶片长度、叶片宽度、株高、结果枝条数、结果数以及株产量均存在显著差异,冠幅之间的差异不显著。5个无性系的2、3、4级枝梢直径以及主杆直径之间的相关性达显著或极显著水平;株高与2、3级枝梢直径以及主杆直径之间具有显著的相关性;1级枝梢长度与1级枝梢直径之间呈显著的负相关关系;叶片长度和宽度之间呈极显著的正相关关系。产量与结果枝条数、结果数以及冠幅之间呈显著或极显著的正相关关系。5个无性系中,HL2-21、FL30分别适宜作抗风固沙、水土保持的生态经济林优良树种。

| Abstract: | In this paper,the plant shape differences of five cashew clones were studied.The correlation among plant shape characters and the correlation between the yield and plant shape characters were analyzed.The results showed that: for trunk height,trunk diameter,the length of the second grade branch,the diameter of the third grade branch,the length and diameter of the fourth grade branch,the differences among the five cashew clones were significant,but for the length and diameter of the first grade branch,the di... |
