不同生长调节剂对新疆秋黑葡萄枝条生长的影响

Effect of Growth Modulator on Grape Branch Growth

在葡萄 (秋黑 )新梢迅速生长期 ,运用ETH、CCC、PP333及IAA 4种调节剂 ,对营养枝、结果枝进行浸蘸试验。方法采用 2种 :1)处理全部副梢及新梢生长点 ;2 )处理部分副梢 ,不处理新梢生长点。结果表明 :除IAA外 ,其它生长调节剂均能抑制枝条的生长。使用浓度为 2 0 0mg/L的ETH、CCC、PP333,可在不影响座果率的条件下明显抑制葡萄新梢的生长。

This paper uses growth modulator including of ETH,CCC,PP333 and IAA to soakage nutrient branch and fructi branch in shoot rapidity growth period.The methods include soakaging both parts of vice shoot and shoot growing point,soakaging part of vice shoot but shoot growing point.The result indicates all of growth modulator can withhold branch growth but IAA,and it can obviously withhold shoot growth but ratio of fruit setting.
