摘要
试验研究了不同矮蔓型西葫芦产量与其构成因素的关系,目的是揭示其产量差异的形成原因。结果表明,矮蔓与半矮蔓品种早期产量差异不显著,总产量半矮蔓品种较矮蔓品种提高25.1%。相关分析表明:总产量与单株结瓜数及单株产量极显著相关,相关系数分别是0.9935和0.9901,与坐瓜率及果实发育速度显著相关,相关系数分别为0.9826和0.9844,与雌花比例相关而不显著;半矮蔓品种产量高于矮蔓品种,主要是其果实发育速度较快、坐果率较高、生育后期单株结果数量多、单株产量显著提高造成的。
Different zucchini varieties were tested for their yield and yield components to reveal the differences in yield for- mation. The results showed that early yields of bush and semi bush varieties were similar, however, total output of semi bush varieties were 25.1% higher than the bush varieties. The correlation analysis showed that total yields were very significantly correlated with fruit number and yield per plant, correlation coefficients were 0.993 5 and 0.990 1, respectively. Yield was significantly correlated with fruit set and fruit development speed with correlation coefficients 0.982 6 and 0.984 4. There was no significant correlation between yield and female flower ratio. The higher yields of semi bush varieties were mainly due to their quick fruit development, high set fruit, higher number of fruit per plant, and higher yield per plant.
