| 摘 要： | 以‘寒富’苹果及其亲本(‘东光’ב富士’)为试材,通过田间调查和解剖学方法,研究‘寒富’苹果短枝型结构特点.结果表明:‘寒富’苹果1 a生枝的平均长度和节间长度小于亲本；枝条粗度、节位数和尖削度高于亲本,具有明显的短枝型性状；‘寒富’苹果叶片厚度和叶脉突起度均大于亲本,叶片的栅栏组织细胞排列为3层,栅栏组织细胞形状较为细长,栅栏组织与海绵组织的比值大于1,叶片的气孔孔径大于亲本,但气孔密度小于亲本.‘寒富’苹果枝条皮部比率大于亲本,为43.11％；材部比率和材/皮小于亲本,分别为56.89％和1.32.由此可看出,‘寒富,苹果短枝型性状较明显,具有典型的矮化特征.

| Abstract: | ’Hanfu’ apple and its parents(’Dong guang’×’Fuji’)were used as materials in this experiment to study the anatomical structural characteristics of ’Hanfu’ apple spur type.The results showed that mean length and internode length of ’Hanfu’ annual branches were shorter than that of its parents,and mean branch diameter,number of nodes and branch taper of ’Hanfu’ apple were higher than that of its parents,which obviously proved to be spur type of ’Hanfu’ apple.Leaves thickness and prominences height of ’Hanfu’ apple were higher than that of its parents which cells of palisade tissue with three cell layers were relative elongated,and the ratio of palisade tissue to spongy tissue was greater than one.Stoma apertures of ’Hanfu’ apple leaves were bigger than that of its parents.However,the stoma density of ’Hanfu’ apple was less than that of its parents.Ratio of branch phloem department was 43.11% which was greater than that of its parents,on the contrary,not only the ratio of xylem department but also the ratio of xylem department to phloem department were less than that of its parents,which were 56.89% and 1.32,respectively.In conclusion,’Hanfu’ apple had obvious characteristics of spur type and typical dwarf traits. |
