摘要
以"和平一号"美味猕猴桃辐射诱变过程所获得的三子叶突变体植株为材料,对猕猴桃三子叶植株的形态特征如单叶长、单叶宽以及叶片气孔分布和表面毛状体等进行观察分析,以获得其与双子叶猕猴桃植株的形态差异信息。结果表明:三子叶植株的单叶长、宽大于正常的双子叶猕猴桃植株单叶长、宽;三子叶植株的气孔数目与双子叶猕猴桃植株的差异不大;三子叶植株叶表面的毛状体比双子叶猕猴桃植株更加浓密,为三子叶猕猴桃育种利用打下基础。
Tricotyledon plants of kiwifruit which obtained from radiation mutagenesis process of Actinidia deliciosa ‘Heping No.1’ were used as material. The morphological characteristics of tricotyledon plants, such as leaf length, leaf width and stoma distribution and leaf surface trichomes were analyzed and observed so that the different information between the tricotyledon plants and dicotyledon plants was obtained according to their morphology. The results showed that the leaf length and width of tricotyledon plants were longer and wider than those of the dicotyledonous plants; the number of stomata on the leaf surface was no significantly difference between the tricotyledon plants and dicotyledonous plants. The trichomes on the leaf surface of tricotyledon plants were denser than those on the dicotyledon plants.
