PBO和芸薹素内酯在甜柿上的应用试验

Trial of Brassinolide and PBO Plant Growth Regulators on Sweet Persimmon

对甜柿盛果期施用PBO和芸薹素内酯的试验结果表明:喷施PBO微量元素水溶肥料3 125 mg/kg、2 500 mg/kg的产量均高于不施药的对照,又以喷施1次3 125 mg/kg的产量较高;喷施1次0.0075%芸薹素内酯水剂375 m L/L液的产量高于对照,但喷施2次的产量略低于对照;喷施PBO微量元素水溶肥料3 125 mg/kg的果肉硬度、可溶性固形物含量较高,其它处理与对照差异不显著。各处理的果实成熟期、品质评价和植株枝叶生长等与对照无明显差异。

Sweet persimmon tree at full bearing age was treated with two plant growth regulators. Compard with control, the fruit yield is getting increased when applied water soluble fertilizer with PBO trace element at both dosages of 3 125 mg per kilogram and 2 500 mg/kg, and 3 125 mg/kg for only one time in particular. Brassinolide at 0.0075% has effect on yield when applied at dosage of 375 m L/L one time, but would lower at twice. The flesh hardness and content of solube solid are higher if treated with PBO at 3 125 mg/kg, and there is no difference among other treatments and control. The fruit mature, sensory quality and plant growth under all treatments are almost the same as control.
