- 摘要:
- 为促进新疆主干形梨树的推广应用，以库尔勒香梨、玉露香梨和新梨7号树冠内膛遮荫果实及光照良好外部果实为试验材料，对比分析了不同光照条件对果实品质的影响。结果表明，与树冠内膛遮荫果实相比，外部光照良好的库尔勒香梨、玉露香梨和新梨7号果实亮度值（L*）分别显著提高了12.87%、7.24%和6.02%；红绿色度值(a*)值分别显著提高了62.88%、46.02%和18.88%，果面色泽好，颜色红；单果重、纵横径有一定提高，但不存在显著性差异；可溶性总糖、可溶性固形物及咀嚼性显著提高，果实的蔗糖、果糖、VC、硬度和有机酸等品质指标有一定改善，但不存在显著性差异。可见，树体外部光照条件良好的果实品质优于内膛遮荫果实，在生产中，应当加强修剪，改善果实光照条件。
- Abstract:
- In order to promote the popularization and application of the main stem-shaped pear tree in Xinjiang, the impact of different light conditions on fruit quality was comparatively analyzed by using the inner canopy shade fruits of Kurla fragrant pear, Yuluxiang pear and Xinli 7 pear and the external fruits with good light as the materials. The results showed that, compared with the canopy inner shade fruits, the external light of good Kurla fragrant pear, Yuluxiang pear and Xinli 7 pear fruit brightness value (L*) were significantly increased by 12.87%, 7.24% and 6.02%.And the reddish greenness value (a*) value were significantly increased by 62.88%, 46.02% and 18.88%, respectively, indicating better color and redder color on the fruit surface.The weight and diameter of single fruit increased, but there was no significant difference. The total soluble sugar, soluble solid and chewability of fruit were significantly improved, and the quality indexes of sucrose, fructose, VC, hardness and organic acid were improved to some extent, but there was no significant difference. It can be seen that the fruit quality in the outer circumference of the tree is better than that in the inner chamber, so pruning should be strengthened to improve the light conditions of the fruit during production.
