1 影响杂交丝瓜制种产量、质量的因素 丝瓜杂交制种单位面积内的产量由种植密度、单株结瓜数、单瓜种子数、千粒重等因素决定 ,且均呈正比例关系 ,种子的产量主要是杂交率和发芽率 (即种子成熟度 ) ,因此整个杂交制种的技术措施应围绕增加单位面积内的采瓜数和提高杂交率和
1 Yield and quality factors of hybrid loofah seed production Yield per unit area of hybrid loofah is determined by the planting density, the number of melon seeds per plant, the number of single melon seeds, the grain weight per thousand, and other factors, and the yield of the seed is mainly Is the rate of hybridization and germination (ie, seed maturity), so the hybrid seed production techniques should focus on increasing the number of melons per unit area and increase the rate of hybridization and
