| 摘 要： | 通过对闽北当年造林邓恩桉幼树高与地径的生长进行定期的观察,总结了该树种在闽北的年节律生长、幼树高、地径的生长规律,分析了年气候变化对该树种幼树高、地径生长的影响和幼树高、地径年生长2个生长高峰发生的原因,同时调查了当年不同地块造林的生长适应性。结果表明,当年生该树种的树高、地径生长分布表现为正态分布,个体生长性状早期表现较大的分化,优势个体在早期已表现显著的遗传优势,适宜早期进行优良表型选择。在抗寒适应性方面,通过冬季2次不同时期霜冻胁迫调查表明,不同个体对低温胁迫表现不同的适应性,抗寒性好的个体,低温胁迫对生长影响较小,仍保持缓慢的生长势,一般抗寒性的,表现为嫩叶叶色变红,而抗寒性较差的表现为顶芽冻死,末梢嫩叶冻坏;不同抗寒性的分化也适宜于耐寒性状的早期选择。

| Abstract: | The growth and changes of height and ground-diameter of Eucalyptus dunnii afforestated during the current year were observed in the northern Fujian.The phenamenon and growth rule of height and ground-diameter of E.dunnii were investigated.The influence of climate change was studied on the growth of height and ground-diameter.The causes of two growth peaks of height and ground-diameter were analyzed.The growth adaptability of was investigated in different planting areas in the current year.The results indica... |
