| 为探索高丛类蓝莓品种在贵州不同海拔生态区的栽培适应性，选择了莱克西、南大、绿宝石、密斯蒂、珠宝、蓝雨等6个品种，分别在海拔760m、1190m、1500m和1850m等4个生态区进行栽培试验。结果表明：莱克西、绿宝石、密斯蒂和蓝雨的树高随海拔高度的升高呈上升-下降的趋势，南大和珠宝则是不断下降，其中珠宝下降趋势最明显，除莱克西以外的5个品种的单株产量也呈显著降低趋势；随着海拔高度的上升，6个品种的新枝萌发力、长势由强变弱，初花期、盛花期、果实成熟期及果实采收期均延后，果实大小也逐渐由大变小。高海拔地区的可溶性固形物、Vc、可溶性蛋白质含量均高于中低海拔，可滴定酸含量则是先上升后下降。所有品种的总花青苷含量与海拔高度呈正相关，绿宝石、密斯蒂、珠宝和蓝雨的氨基酸含量也随海拔高度的升高而增加，其幅度分别为24.45-31.10mg/g、26.83-39.50mg/g、19.64-29.40mg/g、23.82-35.40mg/g。珠宝和蓝雨的挥发性物质含量随海拔高度增加而降低，分别为431.28-141.7μg/g和89.54-46.2μg/g，而南大和绿宝石则相反，为256.24-303.20μg/g和123.52-221.5μg/g。 |
| 英文摘要: |
| Six varieties of highbush blueberry which included Legacy, South big, Emerald, Misty, Jewel and Bluerain were selected to do cultivating experiments in four ecological zones at an altitude of 760m, 1190m, 1500m and 1850m for exploring their adaptability in different altitude ecological areas in Guizhou Province. The results showed that: The tree height of Legacy, Emerald, Misty and Bluerain showed an upward and downward trend with the increase in altitude, while that of South big and Jewel decreased continuously, among which the decline trend of Jewel was the most obvious. The yield per plant of five varieties except Legacy also showed a significant decreasing trend. With the increase of altitude, the sprouting ability and growth of new branches of 6 varieties changed from strong to weak, the early flowering stage, full flowering stage, fruit ripening stage and fruit harvest period were delayed, and the fruit size gradually changed from large to small. The contents of soluble solids, Vc and soluble protein in high altitude were higher than those in middle and low altitude, while the content of titratable acid increased at first and then decreased. The total anthocyanin contents of all varieties were positively correlated with altitude, and the amino acid contents of Emerald, Misty, Jewel and Bluerain also increased with the increase of altitude, and the ranges were 24.45-31.10mg/g, 26.83-39.50mg/g, 19.64-29.40mg/g and 23.82-35.40mg/g, respectively. The content of volatile compounds in Jewel and Bluerain decreased with the increase of altitude, which were 431.28-141.7 μg/g and 89.54-46.2 μg/g, respectively, while those of South big and Emerald were 256.24-303.20 μg/g and 123.52-221.5 μg/g, respectively. |
