无毒(GLRaV-3,GFKV和GRSPa)葡萄组培快繁体系的建立(英文)
发布时间:2025-04-23 00:35
组培、嫁接快繁体系的建立被广泛应用于现代葡萄栽培生产中,以减少生物和非生物胁迫造成的危害。为葡萄种植产业提供无病毒砧木是控制病害的有效途径。本研究中,以"SO4"、"101-14"、"5BB"、"110R"和"1103P"五种常见的葡萄砧木品种为外植体,通过建立组培快繁体系快速获得无病毒葡萄砧木。快繁体系建立结果显示,快繁体系中适合不同砧木启动培养的培养基为MS基本培养基添加0.2 mg/L IBA、1.0 mg/L 6-BA、0.5 mg/L KT、4.0 mg/L腺嘌呤;适合不同砧木继代的培养基为WPM基本培养基添加0.2mg/L IBA,且增殖系数在1.6~4.4之间。病毒检测结果显示,单次RT-PCR检测三种病毒比双重和三重RT-PCR更有效。通过不断继代获得无GLRaV-3,GFKV和GRSPa病毒组培苗进行大棚移栽驯化。幼苗不同霍格兰溶液中室温自然光照下驯化2周,移栽到温室中混合培养基质中,缩短驯化周期。该方案适用于5个葡萄藤砧木品种的快速繁殖,可用于无病毒葡萄砧木的商业化生产。
