- 摘要:
- 为了提高贺兰山东麓酿酒葡萄的果实品质,该试验以酿酒葡萄“北红”为试材,在转色期通过调节叶果比(叶面积∶果粒数,32∶1(CK)、24∶1、16∶1、8∶1),研究了不同叶果比对葡萄果实糖代谢相关酶活性和果实品质的影响。结果表明:转色初期降低叶果比能影响“北红”葡萄果实中转化酶活性和糖分的含量,24∶1处理果实中转化酶和腺苷三磷酸酶(ATPase)活性显著高于CK,可溶性糖含量也显著提高,采收时其果实品质显著高于CK。处理过程中,8∶1处理果实中转化酶活性和糖分含量显著低于CK,采收时果实品质也显著低于CK。因此,在转色期,适宜调节叶果比可以通过调节果实中糖分积累相关酶活性调控糖分的积累,使采收期葡萄果实的品质显著提高。
- Abstract:
- ‘Beihong’ grape was used as material,the effects of leaf-berry ratio treatments(leaf area∶berry grain,32∶1(CK),24∶1,16∶1,8∶1) during early stage of version on sugar metabolism related enzymes activities and berry quality were studied in order to improve grape berry quality in eastern foot of Helan Mountain region.The results showed that invertase activities and soluble sugar content in berry were affected by decreased leaf-berry ratio during early stage of version.Invertase and ATPase activities with 24∶1 treatment significantly increased,sugar content and the berry quality also significantly increased.Invertase and ATPase activities with 8∶1 treatment significantly decreased,soluble sugar content in berry also significantly decreased.During the berry harvest time,the berry quality was lower than CK.So,suitable leaf-berry ratio during early stage of version could improve berry quality though regulated sugar accumulation related enzymes activities.
