Study on Improving Seed Yield of Eggplant
-
摘要: 探讨了不同品种、不同留种方式对茄子制种产量及质量的影响。结果表明,单果种子数以第5层果最多,其余依次为第4层果、第3层果、第2层果;种子质量以第2层果最佳,第3层及第4层果的种子质量居中,第5层果的种子质量最差;通过植株留种部位控制,可提高第3层果及第4层果的种子质量;单株留种方式以第3层留4果,第4层留2果的方式最佳,无论何种方式留种,留种果均不宜超出第4层果;不同品种的单果种子数差异很大,在制种时亲本应选择单果种子数多的品种。Abstract: Different cultivars and seed-fruit reserving ways were investigated to improve seed yield and quality of eggplant. The results showed that the seed numbers per fruit produced by different fruiting layer was ranked as follows: the fifth, the fourth,the third and the second fruiting layer. Fruits on the second fruiting layer produced the best seed quality. The worst seed quality was in the fruits on the fifth fruiting layer.Fruits on the third and fourth fruiting layer produced intermediate seed quality. It could improve the seed quality of the third and fourth fruiting layer by controlling the reserving seed-fruit ways. The best way of reserving seed-fruit was 4 fruits on the third fruiting layer and 2 fruits on the fourth fruiting layer. In spite of all, the reserving seed-fruit was not higher than the fourth fruiting layer. Seed numbers per fruit was significantly difference among cultivars.It was important to select fruit with more seed as mother plant for seed production.
