不同砧木对火焰无核葡萄生长、产量及品质的影响

Effects of Different Rootstock Grafting on the Growth,Yield and Quality of Flame Seedless

【目的】研究不同砧木对火焰无核葡萄生长、产量和品质的影响,为新疆地区栽培优势火焰无核嫁接组合提供科学依据。【方法】以5BB、110R、101-14MG、SO4、188-08等5种砧木嫁接的6a生火焰无核葡萄为试材,火焰无核自根为对照,分析其在田间整个生长周期中树体的生长、产量及发育状况,测定果实色差、粒重、穗重、可滴定酸、可溶性固形物含量等品质指标。【结果】不同嫁接组合葡萄相较于火焰无核自根苗在生长、产量和果实品质均显著或极显著提高。其中火焰无核/101-14MG更能促进火焰无核葡萄早熟。且果实粒重最大,果实着色最好,可溶性固形物含量,固酸比最高。【结论】以101-14MG为砧木嫁接的火焰无核葡萄具有成熟期早、着色好、产量高、可溶性固形物含量高等优点,是5种砧穗组合中最适宜火焰无核葡萄的优良砧木。

【Objective】To study the effects of different rootstocks on the growth,yield and quality of flame-seedless grape and provide a scientific basis for the dominant flame-seedless grafting combination in Xinjiang cultivation.【Methods】5 kinds of grafting the scion of 6 a flame seedless grapes 5BB,11R,101-14MG,SO4 and the 188-08 were taken as test materials,flame seedless self-roots were used as a control to determine such quality indicators as the fruit grain weight,spike weight,color,soluble solids content,titratable acid during the whole growth cycle in the field development and production.【Result】The results showed that the growth,yield and fruit quality of different grafting combinations were significantly or extremely significantly improved compared with the flame seedless self-rooted seedlings.Flame seedless/101-14MG promoted the early ripening of Flame seedless grape and its fruit weight was the largest,the fruit color the best,the soluble solid content and the ratio of solid to acid the highest.【Conclusion】The 101-14MG rootstock grafted with flame-seedless grape has the advantages of early maturity,high yield,good coloring and high soluble solid content,and is the best rootstock for flame-seedless grape among the five kinds of rootstock and ear combinations.
