不同类型黄瓜品种设施栽培的适应性研究

Study on the Adaptability of Different Types of Cucumber Varieties under Protected Culture

对 35个黄瓜品种在冬春茬温室亚适温弱光条件下的生长发育状况进行了研究 ,并依此进行了分类 ,结果表明 :35个黄瓜品种所表现出的植物学特性按类平均法属于主要的 3个类型 ,即欧洲品种、亚洲品种和欧亚杂交种。在亚适温弱光环境下 ,欧亚杂交种植株营养生长和生殖生长均表现最好 :地上部生长健壮 ,根系活性高 ,弱光下结实性强 ,前期产量和总产量均最高。

s The growth and development of 35 cucumber varieties was studied under protected culture. The results showed that 35 cucumber varieties could be divided into three types according to their botanical character with class average mothed. They are European cucumber varieties,Asian cucumber varieties and Europe Asia hybrid cucumber varieties. The Europe Asia hybrid strains have an advantage in vegetative and reproductive growth,with strong plant growth,high root system activity and high yield under sub optical temperature and low light intensity. The European cucumber varieties are superior to Asian cucumber in tolerance to low light intensity.
