摘 要:
Vitis Adenoclada Hand.-Mazz 'Gui Heizhenzhu No.3' in Luocheng and Wuming regions were used as experimental materials to investigate the differences of phenology, fruit quality and climate factors in two regions, and to analyze the correlation between fruit quality indicators. The results showed that the effective accumulated temperature during growing season(April to September), the sum of average temperature in three months before harvest and sunshine hours in Wuming were higher than those in Luocheng. The precipitation of berries in mature months and the hydrothermal coefficient in two months before harvest were higher in Luocheng than in Wuming. The beginning time of each phenophase of 'Gui Heizhenzhu No. 3' in Wuming was 6-17 days earlier than in Luocheng; Luocheng had heavier fruit, more seeds,higher content of resveratrol and tannin than Wuming. In addition, the kinds and contents of volatile metabolites of Luocheng detected in mature fruits were generally higher than Wuming, especially linalool and α-terpineol, which had typical floral terpenes. Correlation analysis showed that berry weight of 'Gui Heizhenzhu No.3' extremely significant positive correlated with fruit longitudinal diameter, transverse diameter and linalool, and positively correlated with fruit L* value and α-terpineol, and negatively correlated with a* value; there was no significant correlation between seed number,seed weight and peel weight of fruit and the contents of resveratrol and tannin. In conclusion, lower temperature and higher altitude were the main reasons for the later phenological period, longer growth period, richer phenols and volatile compounds of 'Gui Heizhenzhu No.3' grape in Luocheng.
