草莓品种抗性生理研究与综合评判

为了探讨草莓品种的抗性生理，在繁苗田中进行了品种、栽植密度与多效唑处理浓度的综合试验，并运用正交试验级差分析和灰色系统理论进行综合评判。结果表明，影响抗性的主要因素是品种，其次是栽植密度；品种抗性的大小依次为硕丰、丰香、绿色种子和宝交早生；最佳处理组合为硕丰每公顷栽７５００株３００ｍｇ／Ｌ浓度多效唑处理。长江中下游地区发展草莓应选择抗性强的优良品种。

Research on resistivity physiology and synthetical judgement for the strawberry varieties

For approaching resistivity physiology of strawberry varieties, a comprehensive experiment was nade.The results is showed that the main factors of effect resistivity is variety ,and then culture density ;the varieties resistivity order is Shuo Feng ,Feng Xiang,Green Seed & Baojiao Aaosheng;The best treat ment is A2B1C1 (variety:Shuo Feng,density:500/mu,Met Concentration:300ppm).Developing strawberry should select good varieties of strong resistivity in the region of the middle & lower reaches of Yangtze River.
