不同类型黄瓜开花和结瓜特性的研究

以4个不同类型的黄瓜为研究对象,研究了不同类型黄瓜在秋拱棚栽培条件下,20节内各节位雌花开放和结瓜的特点及变化规律。研究表明,水果型黄瓜雌性强,开花几率高,单株平均成瓜期13.3d。刺瓜型品种的雌性较其他类型弱,单瓜平均分节数多,雌花成瓜率较高,单瓜质量虽然比其他类型的瓜高1倍左右,但成瓜期短,仅为10.7d。华南型黄瓜和绿白型表现相似,雌性中等,表现出阶段性开花、阶段性结瓜现象。由于第3～6节雌花成瓜率较高,营养消耗大,导致第7～8节的成瓜率和结瓜几率降低。

Study on Flowering and Fruiting Characteristic of Different Cucumber Type

The flowering and fruiting characteristic within twenty nodes of four types of cucumber grown in big tunnel cultivation were studied.The results showed that the fruit cucumber type has strong female and high flowering probability,and the average fruit-produced period is 13.3 days;Prickly cucumber has weaker female than other types,and single fruitweight is twice as much as other types,but fruit-produced period is only 10.7 days;green-white type has similar characteristic,medium female and phased flowering a...
