植物生长调节剂对野生毛葡萄保花保果及其果实品质的影响

Effect of Plant Growth Regulators on Flower-fruit Retention and Fruit Quality of Hairy Grape

研究探讨细胞分裂素(KT-30)、氯吡脲(cppu)、赤霉素(GA_3)和微生物菌液(Y)诱导野生毛葡萄果实膨大、提高座果率、保花保果及其对果实品质的影响。以3年生两性花野生毛葡萄‘野酿2号’作为试验材料,以清水为对照,在挂果前期第一次对果穗分别浸蘸各种生长调节剂及其混合溶液,15 d后根据果粒膨大程度喷施相同浓度的各种生长调节剂及混合溶液。结果表明,在所有处理组中,处理D(cppu-2)、处理A(cppu-1)、处理L(cppu-1)和处理G能获得更理想的效果,均能有效促进果粒的膨大、果穗和果粒的增重、座果率的提高。细胞分裂素(KT-30)、氯吡脲(cppu)、赤霉素(GA3)等植物生长调节剂能有效诱导野生毛葡萄的保花保果作用并提升果实品质。应用灰色系统理论综合评价证明这些处理因子及其组合能获得理想的结果,以处理D(cppu-2)处理的综合效果最好。

The effect of mitogen（ KT-30）,forchlorfenuron（ cppu）,gibberellic acid（ GA_3）,microbe solution（ Y） for berry enlargement,fruit set ratios,flower-fruit retention and fruit quality on hairy grape has been investigated. Using Hairy grape（ Yeniang number 2） with threeyears-old hermaphrodite flower as materials,the first time of instantaneous dipping treatment with various growth regulators or their mixed solution for fruit cluster was carried out,with the water as control,at earlier stage in fruit bearing time when the young fruit size was the same as mung bean at 7 days after full-bloom stage. The fruit clusters or fruits were sprayed with the growth regulators for the second time at 15 days after the first treatment with growth regulators. The result showed： The effects of the treatments of D（ cppu-2）,A（ cppu-1）,L（ cppu-1）,G had more effective than those of the other treatments,they were effective for berry enlargement,ear growth and fruit set ratios. In conclusion,the plant growth regulators,such as KT-30,cppu,GA3,could effectively promote berry enlargement and improve fruit quality,the results also indicate the effectiveness of data analysis in this study with the gray system theory. The best general effect of all the treatments was treatment D（ cppu-2）.
