1、葡萄品种果实性状比较摘要:为了解决遵义市葡萄生产上品种单一问题,并为筛选优良葡萄品种提供基本数据,试验以葡萄品种维多利亚、奥古斯特、红富士、京亚为材料,采用田间试验结合室内测定的方法,对葡萄的果实性状进行比较研究。结果表明,供试葡萄品种的平均单果重、最大穗重存在显著的差异,果形指数、平均穗重在欧亚种内、欧美种内相互无差异,但2个种之间存在显著的差异;在可滴定酸含量上,2个欧美种品种显著高于2个欧亚种品种;在可溶性固形物含量、维生素c含量、总糖含量方面,4个品种之间存在一定的差异。相关分析结果显示,可滴定酸含量与可溶
2、性固形物含量、维生素c含量之间存在显著的正相关性;最大穗重与平均单果重、平均穗重之间存在极显著的正相关性,果形指数与平均穗重、平均单果重之间存在显著的负相关性。综合比较而言,4个葡萄品种在遵义市可以正常开花结果,能适应当地的自然环境。在避雨栽培方式下,4个品种果实的性状虽然存在一定的差异,但品质都在中上水平,其中欧亚种品种在遵义市的表现要优于欧美种品种。关键词:葡萄;品种;果实性状;比较;遵义市abstract:tosolvetheproblemofsingle-varietyofgrapeproductionin
