摘要
在 7月初柑定果期用 10 0～ 2 0 0mg/L细胞分裂素BA(N6 苄基腺嘌呤 )叶面喷布桔树 ,可显著促进果实的生长和膨大。处理组果实横径≥ 6 .5cm的大桔果百分率较对照增加 7.51～ 2 2 6 5个百分点 ,而横径 <5.5cm的小桔果百分率则较对照减少 12 .59～ 2 4 .6 6个百分点 ,且增加了单果重。BA促进果实增大的效应随施药时间的提早而增强。BA处理还可提高果实的固形物、总糖、Vc和还原糖的含量 ,降低总酸含量 ,使果实品质得到改善。3H 葡萄糖标记试验结果表明 ,BA促进柑果实增大与其加剧标记叶同化产物的输出 。
The trees of Pon Kan ( Citrus reticulata cv Pon Kan) were sprayed with BA (benzyl adenine) at 100-200 mg/L after fruit setting (5 July).The results showed BA enhanced fruit enlargement and increased weight per fruit.The percentage of large size fruit (transverse diameter≥6.5 cm)increased 7.51 to 22.65 than that of the control,and,the percentage of small size fruit (transverse diameter<5.5 cm)decreased 12.59 to 24.66. The effect of BA on fruit enlargement was strengthened by earlier application.BA increased the contents of TSS (total soluble solids),total sugars,reducing sugar and vitamin C,but it decreased the content of fruit acid.Thus the fruit quality was improved.The 3 H glucose experiment showed the effect of BA on fruit enlargement was related to the fact that it accelerate the export of assimilate from the labeling leave and improved the assimilate transport to fruits.
