摘    要:【目的】研究不同浓度矮壮素(CCC)对巨峰葡萄春季新梢生长的影响,为夏季葡萄落花落果、产量低等问题提供解决方法。【方法】以6年生棚架式栽培巨峰葡萄为试材,用体积比分别为300、500和750倍的矮壮素处理新梢,清水作对照,分析不同浓度矮壮素对不同催芽时间以及不同长势的新梢长度、第6节新梢粗度和第10节节间距的影响。【结果】186日催芽的旺枝,新梢经300、500和750倍矮壮素处理后28d梢长度分别为130.60、148.67、143.47cm,明显短于对照,300倍处理与对照差异极显著(P〈0.01,下同),与500、750倍处理差异显著(P〈0.05,下同);1月13日催芽的旺枝,处理后7d,300倍矮壮素处理的新梢长度(85.00cm)短于对照,差异极显著,与500、750倍处理差异显著。1月6日催芽的中庸枝,处理后28d,经300倍矮壮素处理的新梢长度(111.14cm)短于750倍处理和对照,差异极显著;1月13日催芽的中庸枝,新梢经300倍矮壮素处理后的长度(106.67cm)明显短于对照。1月13日催芽的旺枝长出的新梢,300倍处理后28d第6节新梢粗度(10.42mm)显著高于对照。1月13日催芽的中庸枝,经300倍矮壮素处理的新梢,处理后7d第6节粗度(8.36mm)粗于对照和其他两个处理,差异极显著;处理后28d,300倍处理的第6节新梢粗度(8.19mm)粗于对照,差异显著。两个催芽时间,处理后7d不同浓度矮壮素对新梢第10节节间距之间的影响无明显差异;其他催芽时间、不同浓度矮壮素对枝条的增粗生长都有一定的促进作用。【结论】矮壮素对过旺生长的葡萄新梢有抑制作用,尤其以体积比300倍的矮壮素抑制效果最佳,可用于葡萄春季控梢。

Abstract:Objective]We researched the effects of cycocel (CCC) at different concentrations on one-year-two- harvest "Kyoho" grape shoot growth to provide solutions for dropped flowers and fruits as well as low yield caused by the summer grape fruit excessive vegetative growth. Method]Six-year-old scaffolding-cultivated "Kyoho" grapes were used as test materials. The shoots were processed with different concentrations of (CCC) at the volume ratio of 300 times, 500 times and 750 times and sprayed clean water as control to analyze the effects of (CCC) on accelerating germination time, new shoot length with different growth potential, new shoot roughness of the sixth node, and section spacing of the tenth node. Result ]After the vigorous branch germinated on 13^th Jan was treated by 300 times of (CCC), 500 times and 750 times, the new shoot length on the 28 d was 130.60, t48.67 and 143.47 cm, significantly shorter than that of the control. The results from 300 times were extremely significantly different from those of the control and significantly different from those of 500 times and 750 times. After the moderate vigor branch germinated on 6^th Jan was treated by 300 times,the new shoot length on the 28 d (111.14 cm)was shorter than that of 750 times and the control. The difference was significant. After the moderate vigor branch germinated on 13^th Jan was treated by 300 times of (CCC), the new shoot length (106.67 cm)was evidently shorter than that of the control. After the new shoot grown from the vigorous branch on 13^th Jan was treated by 300 times of chlormequat, the sixth new node diameter on the 28 d (10.42 mm)was evidently higher than that Of the control. After the new shoot grown from the moderate vigor branch on 13^th Jan was treated by 300 times of (CCC), the sixth new node diameter on the 7 d (8.36 mm)was evidently higher than that of the control and the other two treatments. The difference was significant.The sixth new node diameter on the 28 d (8.19 mm)was evidently higher than that of the control and the difference was significant. The two germination dates and concentrations of (CCC) after 7 days had no obvious variation on the tenth node spacing but branch roughness was promoted. Conclusion ] (CCC) especially 300 times of (CCC) could hinder the excessive growth of new grape shoots, hence it should be used for grape shoot growth control in the spring.
