尽管青椒以自花授粉为主,但也有较高的自然杂交率。要保证品种的纯度必须进行隔离。1987年,我们用扣不同颜色纱罩对青椒的采种量和产量作了对比分析,结果证明,白纱罩内青椒的小区产量和采种量最高,而日灼果显著减少。目前,国内外学者对这方面的研究尚不多见,故将我们进行的初步试验作以介绍。 Although green pepper is dominated by self-pollination, there is also a high rate of natural hybridization. To ensure the purity of varieties must be isolated. In 1987, we made a comparative analysis of the seed volume and yield of green peppers by using different colors of gauze cover. The results showed that the yield and the seed quantity of the green peppers in the white gauze cover were the highest, while the number of the sunburning fruits was significantly reduced. At present, domestic and foreign scholars are still rare in this area, so we will introduce the preliminary experiments.
