摘要
以引进的＂黄玫瑰＂、＂白罗莎里奥＂、＂香妃＂和＂醉金香＂4个葡萄品种为试材,对其结果母枝粗度、结果枝粗度、结果枝上第1花穗长度和第1果穗长度的数量分布以及相关性进行了研究。结果表明：各品种结果母枝、结果枝粗度、第1花穗长度和第1果穗长度均表现出集中分布的现象。各品种结果母枝粗度均集中分布在（1.00±0.30）cm之间;＂白罗莎里奥＂结果枝较细,绝大多数分布在1.10cm以下,而其它品种集中分布的范围是（1.00±0.20）cm;＂黄玫瑰＂花穗偏小,多在10cm以下,＂白罗莎里奥＂花穗较大,多在12cm以上,而＂香妃＂和＂醉金香＂居于中间,多在（10.0±0.30）cm范围内;＂黄玫瑰＂的果穗偏小,集中分布在13cm以下,而其它品种均集中分布在13~20cm。相关分析表明,除了＂白罗莎里奥＂外的品种结果母枝粗度与结果枝粗度间未有显著相关性;除＂白罗莎里奥＂外,其它品种的结果枝粗度与第1花穗长度间均存在极显著的正相关性;除＂香妃＂外其它品种的结果枝粗与第1果穗长度间没有显著相关性;所有品种的第1花穗长度与第1果穗长度间均存在极显著的正相关性。这说明健壮的结果枝上抽出的花穗要大,可以根据开花前花穗的长度来推断未来果穗的长度。
With ＇Yellow Rose＇,＇Rosario Bianco＇, ＇Xiangfei＇ and ＇Zui Jinxiang＇ four introducted grape varieties as materials, their quantitative distribution and relationships of base fruiting shoots, fruiting shoots, flower clusters and fruit clusters were studied. The results showed that, the diameters of base fruiting shoots and fruiting shoots, the lengths of flower clusters and fruit clusters showed phenomenon of concentrated distribution for all varieties. Diameters of base fruiting shoots of all varieties were concentrated in （1.00 ± 0. 30） cm. ＇ Rosario Bianeo＇ fruiting shoots were finer and concentrated below 1.10 cm, other varieties were concentrated in （1.00 ±0. 20）cm. Flower clusters of ＇Yellow Rose＇ were smaller,most below 10 cm; those of ＇Rosario Bianco＇ were larger,most above 12 cm,and those of ＇Xiangfei＇ and ＇Zui Jinxiang＇ were in the middle,most in （10. 0±0. 30）cm. Fruit clusters of ＇Yellow Rose＇ were smaller too and most were below 13 cm, those of other varieties were concentrated between 13-20 cm. Correlation analysis results showed that diameters of base fruiting shoots and fruiting shoots had no significant correlation among most varieties; there were a significant positive correlation between the diameters of fruiting shoots and the first flower clusters for the other varieties except ＇Rosario Bianco＇ ,there were no significant correlation between the diameters of fruiting shoots and the first fruit clusters for the other varieties except ＇Xiangfei＇, and there were significant positive correlation between the first flower clusters and the first fruit clusters for all varieties. These suggested robust fruiting shoots could occur bigger flower clusters and the flower cluster length before the blossom could forecast the length of fruit cluster.
