通过对大白菜品种春化采种效应的研究,探讨了不同大白菜品种春化采种情况,确定了我省栽培的二牛心、牡丹江一号、矬菜四号品种种子春化处理的适宜日数,为进一步了解各品种的冬性。苗期取样镜检观察了不同品种、不同春化处理时间、不同苗令花芽分化的快慢、为大白菜春化采种和配制杂交组合提出一定理论依据。试验设计系采用与春化有关的三因素各设置三个水平的正交试验,重复三次,小区长5米,面积14平方米。苗令分别为28、33、38天;种子春化处理日数分别为35、25、1S天。通过对不同处理组合的种子产量、生育期等经济性状和植物学特性进行调查分析.以选取最佳组合。
By studying the effect of vernalization on the Chinese cabbage varieties, the spring planting conditions of different Chinese cabbage cultivars were discussed, and the suitable days for the vernalization of the seeds of Erdosxin, Mudanjiang No.1 and 矬cao4 were determined. For further understanding of the winter of all varieties. Seedling microscopic observation of different species, different vernalization treatment time, different seedling flower bud differentiation speed, the Chinese cabbage vernalization and preparation of hybrid combinations provide a theoretical basis. The experimental design uses three factors related to vernalization. Each set of three levels of orthogonal test, repeated three times, cell length of 5 meters, an area of 14 square meters. Miao Ling were 28,33,38 days; seed vernalization days were 35,25,1 S days. The economic traits and botanical characteristics such as seed yield and growth period of different treatments were investigated and analyzed to select the best combination.
