- 摘要:
- 以洋葱品种“钻石红”为试材，采用随机区组试验设计方法，研究了不同抽薹数母株在群体中的百分率，以及不同抽薹数母株种子的单株产量、单花球产量、种子净质量率、种子千粒质量和种子的发芽率等，以期对洋葱的繁种和选种提供技术支持。结果表明：抽薹数为5个的植株群体最大，达23.75%，4~7个花薹数的母株较多，总和达到76.88%，2个花薹的植株最少，仅为1.25%；抽薹数越多，单株产量越高，10~11个花薹的单株种子产量最高，平均达69.7 g，2个花薹的最少，只有11.5 g；单个花球的种子质量随着抽薹数增多而减少；种子净质量率呈现两侧高中间稍低的趋势；不同抽薹数种子千粒质量差异显著，最大值是3.966 g，最小值是3.235 g，但规律性不明显；不同抽薹数种子发芽率差异不显著，最高98.0%，最低92.6%，没有明显的规律性。
- Abstract:
- The onion variety ‘Zuanshihong’ was used as material,the percentage of seed plants with different bolting numbers in the group,the seed yield per plant,single flower bulb yield,net seed weight rate,thousand seed weight and seed germination rate of seed plants with different bolting numbers were studied by using the method of randomized block experiment design and conventional cultivation in order to provide technical support for onion breeding and seed selection.The results showed that the group with 5 bolting numbers were the largest,reaching 23.75%.The total number of seed plants with 4-7 bolting numbers were more,reaching 76.88%.The plant with 2 bolting numbers were the least,only 1.25%.The more bolting the higher yield per plant.The highest seed weight per plant was 10-11 bolting plants,the average was 69.7 g,and the lowest was 2 bolts,only 11.5 g.The seed weight of a single flower bulb decreased with the increase of bolting number.The net weight rate of seeds showed a slightly lower trend between the two sides；the 1 000-seed weight of different bolting numbers had significant difference,the maximum was 3.966 g,the minimum was 3.235 g,but the regularity was not obvious；the germination rate of seeds with different bolting numbers had no significant difference,the highest was 98.0%,the lowest was 92.6%,and there was no obvious regularity.
