摘要:
葱属蔬菜种类丰富,在蔬菜生产中占有重要地位。葱属蔬菜种子寿命短,在储存中生活力易下降甚至丧失。本试验以国家蔬菜资源中期库中保存的 6 种葱属蔬菜共 610 份资源为研究对象,其中包括韭菜 267 份、大葱 226 份、分葱 40 份、洋葱 67 份、韭葱 8 份、南欧蒜 2 份。对其发芽率测定,结果表明:经过 21~30 年的储存后,6 种葱属蔬菜种子的生活力均呈现显著下降趋势,其中以分葱和洋葱最为严重;入库时的种子发芽率严重影响着种子在贮存期间的生活力;同一种葱属的不同基因型间也表现出寿命长短差异。

Abstract:
Vegetables of the genus Allium L. with high diversity are very important in the vegetable production. The viability of the short-lived seed of Allium is easily reduced or even lost during storage. A total of 610 accessions of 6 species of allium vegetables in the National Medium-term Genebank of Vegetable Germplasm Resources, including 267 accessions of A. tuberosum Rottler ex Spreng., 226 accessions of A. fistulosum L., 40 accessions of A. ascalonicum L., 67 accessions of A. cepa L., 8 accessions of A. porrum L., and 2 accessions of A. ampeloprasum L. were evaluated for seed germination. The results indicated that the seed viability of the 6 species of allium vegetable resources declined significantly after 21-30 years storage, with A. ascalonicum and A. cepa the most seriously, that the initial germination percentage of the seeds put in storage heavily affected the viability of the seeds during storage, and that the different genotypes of the same species of allium vegetables also showed difference in longevity.
Key words:  National Medium-term Genebank of Vegetable Germplasm Resources  allium vegetable genetic resources  seed viability monitoring
