矮壮素对日光温室红地球葡萄树势调控和果实生长的影响

Effect of CCC on Tree Growth and Fruit Development of Red Globe Grape in Greenhouses

通过对比试验研究了不同矮壮素(CCC)浓度在不同时期喷施对日光温室红地球葡萄新梢生长和果实发育的影响。结果表明:不同时期喷施矮壮素后,叶面积、枝条节间距和长度随着喷施浓度的增加而降低,叶厚和枝条粗度随着喷施浓度的增加而增加。同一处理浓度在花前的处理效果优于花后处理。在所有浓度中花前用矮壮素500倍液处理葡萄后,葡萄穗重、单粒重、叶绿素含量和可溶性固形物含量最高,建议在日光温室红地球葡萄栽培中花前采用矮壮素500倍液来调控葡萄枝条生长。

Effects of different CCC times on regulating shoot growth and fruit development of red globe grape in greenhouses are studied in different period by contrast test. The result showed that leaf area,pitch length,shoot length are decreased with CCC times increased,and leaf thickness,shoot roughness are increased with CCC times increased. The effect before flowering is better than the effect after flowering to same CCC times. The cluster weight,single fruit weight,chlorophyll content,soluble solids content of CCC 500 times treating before flowering are the highest in all treatments,the CCC 500 times treating before flowering is suggested to control shoot growth of red globe grape in greenhouses.
