摘要: 为研究不同树形及不同花穗整形长度(3、5、7、9 cm)对夏黑葡萄果实性状及果实品质的影响;选用2 种树形及5 种花序整形长度的处理方法进行试验。结果表明:采用“T”字型棚架树形,可以增加穗重、提高果实还原糖含量、降低果实可滴定酸含量,而十字飞鸟架形增加了果粒质量和可滴定酸含量;随花序整形长度的增加,果穗长度、果穗宽度、果穗质量呈增加的趋势变化,而果粒质量、果粒纵径呈降低的趋势变化;不同花穗整形长度果实的还原糖含量均显著高于对照,可滴定酸含量均低于对照;综合看,保留花穗长度5~7 cm是夏黑葡萄适宜的穗形长度。

Abstract: The paper aims to study the effects of different tree forms and lengths of flower thinning (3, 5, 7, 9 cm) on fruit qualities of summer black grape, the authors selected two tree forms and 5 kinds of flower thinning to do the experiment. The results showed that: the grape trellis of“T”could increase the weight of fruit cluster and the content of reducing sugar while decreasing the content of titratable acid, meanwhile, the trellis of ‘Cross Asuka Frame’increased the weight of cluster and the content of titratable acid; with the increasing of the length of inflorescence, the length and width of cluster and the weight of fruit showed an increasing trend while the vertical and horizontal diameters of fruit and the weight of single berry showed a decreasing trend. Compared with the control, different treatments had higher reducing sugar content and lower content of titratable acid. In a word, keeping the length of spikes from 5 cm to 7 cm is suitable for spike-shaped length of summer black grapes.
