摘要
为认识葡萄品种资源果刷特征以及果刷脱落后对果粒的影响,本研究对126个葡萄品种成熟期的果刷性状以及74个品种果洞褐化情况进行分析,研究结果表明,果刷特性在品种之间存在一定差异。果刷可分为完整和不完整两类,果刷拔出后粘连果肉情况不同,欧亚种果刷与果肉粘连程度高于欧美杂种(V. vinifera L.×V. labrusca L.);欧亚种葡萄果刷耐拉力与果刷长度、果刷粗度之间均呈极显著正相关;欧美杂种葡萄果刷耐拉力与果刷长度之间相关性不显著,与果刷粗度之间呈极显著正相关;欧亚种与欧美杂种葡萄果刷耐拉力之间存在显著性差异,且欧亚种耐拉力明显大于欧美杂种葡萄品种耐拉力;果肉褐化速度和褐化程度在品种间差异大,且成熟度愈高褐化程度愈轻。不同品种果洞褐化速度不一致,果洞的大小不同对果实造成损伤程度有异,在一定程度上影响采后果实的耐贮性,通过对果刷性状的研究,以期为葡萄种质资源评价以及新品种的育种工作提供一定的理论依据。
In order to understand the characteristics of fruit brush in grape cuhivars, this study analyzed the fruit brush related traits in 126 grape cultivars and the fruit hole browning in 74 varieties at the ripening stage. The results show that there are some differences in the characteristics of fruit brush between varieties. For instance, the fruit brush is either complete or incomplete, and the condition of sticking pulp is different when the brush is pulled out. Vitis vinifera L. fruit brush and pulp adhesion is higher than V. vinifera L. × V. labrusca L.. There was a signifi- cant positive correlation between the pull resistance of Vitis vinifera L. grape fruit brush and the length of fruit brush and the thickness of fruit brush ; however, there was no correlation between the pull resistance of V. vinifera L. x V. labrusca L. grape fruit brush and the length of fruit brush, but there is a significant positive correlation between brush thicknesses and the pull resistance. In addition, the pull resistance of Vitis vinifera L. species was significantly greater than that of V. vinifera L.× V. labrusca L.. The browning speed and browning degree of the flesh are differ- ent among the varieties, and the higher the maturity, the lower the browning degree is. The browning speeds of differ- ent varieties of fruit holes are inconsistent, and the different sizes of fruit holes cause different degrees of damage to the fruit, which affects the storage stability of the postharvest fruit to a certain extent. By deciphering the diversity offruit brush, this work provided a considerable theoretical basis in evaluation of grape germplasm resources and in breeding of elite varieties.
