| 摘 要： | 以5年生红地球葡萄为试材,分别进行留穗尖8 cm、10 cm、12 cm、14 cm、16 cm及剪短小分枝、去上去下留中间和去主穗留副穗8种整穗处理,研究了不同花穗整形方式对红地球葡萄果实品质的影响,筛选出红地球葡萄省工、优质的整穗方式。结果表明:留穗尖10 cm的单粒质量最大,留穗尖8 cm、12 cm和16 cm的可溶性固形物含量明显高于其他处理,留穗尖12 cm和14 cm的单宁含量显著低于其他处理,留穗尖8 cm、10cm和12 cm均要比去上去下留中间整穗有利于着色。留穗尖12 cm的综合效率最高,留穗尖14 cm综合效率最低。不同整穗方式的主成分综合评价结果为,留穗尖12 cm留穗尖10 cm留穗尖8 cm去主穗留副穗方式剪短小分支式整穗留穗尖14 cm留穗尖16 cm去上去下留中间式整穗。确定留穗尖12 cm是红地球葡萄省工、提质的较佳花穗整穗方式,可为我国红地球葡萄花穗整形提供理论依据。

| Abstract: | Taking 5-years-old Red Globe grape plants as tested material, this paper investigated the effects of different floral clusters pruning methods on fruit quality of Red Globe grape; and screened out labor saving, pruning method with high quality. The results showed that the single-grain weight by leaving spikelet tip 10 cm was the highest. The soluble solid contents by leaving spikelet tip 8 cm, 12 cm and 16 cm were significantly higher than that of the other treatments. The tannin contents of leaving spikelet tip 12 cm and 14 cm were significantly lower than that of the other treatments. Among treatments, leaving spikelet tip 8 cm,10 cm and 12 cm were more conducive to coloration than the treatments of shorting branch, retaining middle ear. Leaving spikelet tip 12 cm could obtain the highest comprehensive efficiency. While, the efficiency of leaving spikelet tip 14 cm was the lowest. The comprehensive evaluation results of different pruning methods were in ranks of leaving spikelet tip 12 cm>10 cm>8 cm>remaining the secondary ear>only shorting branch>leaving spikelet tip 14 cm>16 cm>retaining middle ear. Hence, leaving spikelet tip 12 cm should be the best floral cluster pruning method with labor saving and high quality for Red Globe grape in production practice. This study provided theoretical basis for floral cluster pruning of Red Globe grape. |
