摘要:

西红花只能通过无性繁殖方式繁育球茎,探索培育开花大球茎与增加后代子球茎数量之间的平衡点,可以为西红花栽培与生产过程中规模的进一步扩大奠定理论基础。以4个等级单球重(8~15、16~20、21~25、26~30 g)的西红花球茎为材料,通过抹除侧芽与不抹芽对比试验,分析其后代子球茎的数量、质量及开花时间、开花量等数据。结果表明,球茎单球重越大,能形成子球茎的数量越多。未抹芽的子球茎生物量整体呈增加趋势,但单株子球茎均重和主芽子球茎均重均整体呈下降趋势。单球重20 g以上的母球,可以保留芽数量最多至5个左右,既能得到更多的子球茎,也不影响新形成顶芽球茎开花及开花量。

Abstract:

Crocus sativus is propagated exclusively in a vegetative way by corms, and to explore the balance between cultivating large flowering corms and increasing the number of replacement corms can lay a theoretical foundation for the further expansion of production scale of C. sativus. Four grades of C. sativus corms with different weights (8-15, 16-20, 21-25 and 26-30 g) were used as materials, the number, weight, flowering time and flowering number of the replacement corms were analyzed under the comparative experiment by wiping or not wiping lateral buds of mother corms. The results showed that the larger the weight of the corm, the greater the number of replacement corms could be formed. The biomass of replacement corms from not wiped mother corms showed an overall increase trend, but the average weight of the corms from one mother corm and the average weight of the corms from the main bud showed an overall downward trend. The single mother corm of more than 20 g could retain the number of buds up to about 5, which could get more replacement corms and did not affect the flowering and flowering number of newly formed corms from the main bud.

Key words: Crocus sativus, lateral bud, replacement corm, flowering number, flowering time
