| 摘 要： | 2005年以来,在广东地区大面积桉树人工林无性系出现了＂生长停滞症＂的现象,为了确定该症是否与微量元素有关,本研究采用具有典型生长停滞症状和林分健康3个样品组的尾叶桉U6成熟叶片进行了微量元素检测和分析。结果表明3个样品组叶片在微量元素B、Cu、Zn、Mn含量上存在极显著差异,对3个样品组的15个样品聚类分析表明,立地间存在显著差异。进一步对来源同立地的10个样品进行聚类分析,发现具有生长停滞症的样品基本上分为一类,而林分健康的样品基本上分为一类。以上结果表明桉树生长停滞症与桉树微量元素的含量存在一定程度的相关性。

| Abstract: | Symptom so called slow-growing had been observed on eucalypt plantations in Guangdong in the past few years.In order to test whether the symptom was caused due to the deficiency of trace elements,concentrations of B,Cu,Zn,Fe,Mn elements were measured from both healthy and diseased mature leaves of Eucalyptus urophylla (U6) .The results showed that there were significant differences of concentrations of B,Cu,Zn,Mn between healthy and diseased leaves.The cluster analysis of 10 samples,5 healthy and the other ... |
