| 摘 要： | 对柑桔50个品种类型应用11种矮化效应预选指标进行测试。结果指出,春叶下表皮气孔密度、枝电阻值、节间长度与实生树的株高、干粗呈极显著的正相关,枝皮率、叶上表皮细胞大小、春叶厚与实生树株高、干粗呈极显著的负相关。叶气孔密度和枝皮率与嫁接树的株高、树冠体积呈显著相关,可作为矮化效应预选的主要指标。并对供试品种类型排出矮化序列,还探讨提高测定的准确性和重现率,注意取样代表性等问题。

| Abstract: | About 11 indices of dwarfing effect in 50 citrus species and varieties were studied. The results showed there were very significant positive or negtive correlations among the stoma density of hypoderms in spring leaves, the resistance value in twigs, the length of internodes, the bark percentage in relation to thickness of twig (BPHT), the size of epicuticle cell in leaves and the thickness in spring leaves, with the height of seedlings and the diameter of trunks. The stoma density in leaves and BPHT showed significant correlations with the height and crown volume of grafted trees. The stoma density in leaves and BPHT can be used as the main indices of dwarfing effect. The dwarfing sequences in 50 species and varieties were arranged. The correlations between the above indices and how to lower the experimental error in sampling were also studied. |
