摘要
以6年生玫瑰香葡萄为试材,研究了Y型架和篱架不同叶幕层的光照强度和产量分布,测定了果实品质和芳香化合物。结果表明:两种架型的光照强度与叶幕层高度、宽度分布有显著的相关性,Y型架在高0.2～0.6m和1.8m处的光照强度优于篱架;但在1.0～1.4m则低于篱架。Y型架61.61%的产量集中在定植行两侧0.3m,高度1.0～1.4m的范围内;篱架55.90%的产量集中在定植行两侧0.15m,高度0.6～1.0m的范围内。Y型架果实总糖和抗坏血酸含量分别为16.13%和8.72mg·kg-1,显著高于篱架(14.54%和7.21mg·kg-1);Y型架果皮原花色素含量为4.72mg·g-1,显著低于篱架(6.30mg·g-1)。Y型架和篱架果实中检测到芳香化合物种类为32种和30种;萜醇化合物的相对含量分别为32.91%和6.33%;其中,Y型架果实中里那醇的相对含量是篱架的5.7倍,可见,Y型架葡萄果实风味优于篱架。
Six-year-old‘Muscat Hamburg’grape was used as the material to study the difference in relative light intensity,yield distribution of leaf canopy,fruit quality and aromatic compounds between 2 types of grape trellis Y frame and vertical trellises. The results showed that there was significant correlation between light intensity,height and width of leaf canopy. The areas with 0.2–0.6 m and 1.8 m in Y frame showed higher photosynthetic than vertical trellises,but the areas with 1.0–1.4 m were lower than vertical trellises. Total sugar and ascorbic acid content was 16.13% and 8.72 mg·kg-1 in the fruit of Y frame,which were significantly higher than 14.54%,0.40%,16.12% of vertical trellises. However,the procyanidins in the fruit of Y frame was 4.72 mg·g-1 that was significantly lower than 6.30 mg·g-1 of vertical trellises. Thirty-two kinds of aromatic compounds were detected in Muscat Hamburg grape of Y frame,which was significantly higher than thirty kinds of vertical trellises,and there was significant difference in the aromatic compounds contents as well. The relative content of terpenols in the fruit of Y frame was 32.91% that was higher than 6.33% of vertical trellises,and the linalool content in the fruit of Y frame was 5.7 times as much as vertical trellises. These results show that the flavor of grape fruit of Y frame was better than vertical trellises.
