苏南丘陵地区葡萄生长发育规律调查与研究

Investigation and Study on Growth-development Regulation of Grapes in Hilly Area of South Jiangsu

[目的]研究苏南丘陵地区不同生态型、不同熟期葡萄生长发育规律。[方法]从9株生长相似的5年生植株上,选取葡萄主枝上前、中、后部的3根枝条,调查主要物候期,测定萌芽率、新梢长度、新梢直径、落花落果情况、花序长度、果实品质等。[结果]中早熟品种的萌芽期均早于晚熟品种,白罗莎里奥和夏黑萌芽率高于巨峰和魏可,白罗莎里奥的花序最长;魏可的果实硬度、可滴定酸高于其他品种。[结论]该研究可为苏南丘陵地区葡萄生产提供实践依据。

[ Objective] Growth regulation of grapes with different ecotypes and ripening periods was studied in hilly area of South Jiangsu.[Method] 27 shoots of the tip, middle and rear on the main boughs were selected from 9 plants with 5-year old and growing similarly. The main phenological period,germination-percentage, new shoot length, new shoot diameter, inflorescence length, blossom＆fruit-drop and fruit quality were investigated. [ Result] Germination period of early and mid-maturation varieties was earlier than late-maturation ones. Germina-tion percentage of Rosario Bianco and Summer Black was higher than that of Kyoho and Wink, inflorescence length the longest. Fruit hardness and titratable acid of Wink were higher than other varieties. [ Conclusion] The study can provide practical basis for grape production in hilly ar-ea of South Jiangsu.
