摘  要:
对猕猴桃品种“秦美”不同黄化程度树叶片质量、树体生长、结果、果实品质进行了研究。结果表明,黄化树叶片大小、厚度、比叶重分别较非黄化树减少了 13. 7% ~28. 7%、13. 1% ~23. 4%、8. 4% ~13. 8%;黄化树叶片叶绿素含量明显减少,叶绿素含量仅为正常树的83. 6% ~62. 0%;黄化树萌芽率、成枝率、果枝率及每果枝结果数明显下降,仅为非黄化树的72. 0% ~87. 7%、51. 9% ~69. 2%、56. 6% ~93. 4%、53. 1% ~81. 6%;果实小、品质差,且随树体黄化程度的加重而加剧。

摘  要:
The effect of iron deficiency chlorosis on growing , fruiting and fruit quality of ‘Qinmei’ kiwifruit tree were studied. The results showed that the size, thickness and dry weight per unit of leaf decreased by 13.7%~28.7%,13.1%~23.4% and 8.4%~13.8% respectively. The amount of chloroplast reduced significantily, and was only 83.6%~62.0% of normal tree. Iron deficiency chlorosis also induced the decrease of fruit size, bud bursting ratio, longer shoots ratio, fruiting shoots ratio and fruit number per shoot and caused inferiority of fruit.
