瓜重、瓜数与杂交一代制种量相关的研究
Relationship between Seed-producing Number of Xinnong Watermelon Hybrid F1 and Their Productivity

摘要: 本研究探讨了兴农西瓜瓜重、瓜数与杂交一代产籽量的相关性。结果表明:春季制种单瓜重与种籽粒数的相关区间在0.4—4.8kg,秋季制种其相关区间在0.4—3.8kg区间内都呈二次指数方程正相关;两季制种单瓜重在0.4—3.0kg区间内产籽量随瓜重增加而近似直线上升;单株产籽量随瓜数的增加而成自然对数方程正相关,其种籽百粒重和质量经方差分析和试验无显著差异。据此结论是:控制瓜重在3.0kg内,主要着眼点是力增结瓜数,以达到增加单位面积产籽量的目标要求。Abstract: The relationship between seed-producing number of Xinnong watermelon hybrid F1 and their weight and fruit-bearing number has been determined.The results showed that the correlative range between onemelon weight and its seed number during spring and autumn seasons is positively related from 0.4 to 4.8 kg and 0.4 to 3.8 kg respectively, belongs to the quadratic exponential equation.Within the range of 0.4 -3.0 kg one-melon weight, the seed-producing number increases linearly with the increase of melon weight in both two seed-producing seasons.The seed-producing number per plant is positively related to the increase of melon-bearing number.and belongs to the natural logarithm equation.But 100-seed weight and quality showed no significantly difference by the variance analysis.Thus, the measures for increasing seed-producing number in given area include two respects: (1) To increase watermelon number per plant; (2) To limit the watermelon weight below 3.0 kg.
