摘　　要：播种期对ＳＧ２５９和Ｐｒｏｖｉｄｅｒ两个矮生菜豆品种的物候期、结实能力、种子产量和品质均有明显的影响。从播种（出苗）到始花所需的时间春播较秋播长；秋播时，则随着播种期的推迟而延长；从开花到种子采收所需的时间是秋季较春季长。春播的单株分枝数较秋季多，而单株结荚数则是以７月２５日前后播种的较多。ＳＧ２５９的小区种子产量以７月下旬播种的较高，而Ｐｒｏｖｉｄｅｒ则是以３月３日和７月２５日播种的较高；种子品质以７月下旬播种较为理想。结果表明，杭州地区矮生菜豆种子的生产适宜播期在７月２５日前后。In order to study the influence of sowing date on seed yield and quality, two dwarf bean cultivars, SG259 and Provider, were used with six sowing dates. Seeds were sown on Mar. 3 in spring, and from July 20 to Aug. 9 at 5-day interval. It was found that sowing date influenced markedly on phenophase, number of branches and pods per plant, seed yield and quality (1000-seed weight and seed germination percent). Days from sowing to blooming sown in spring were longer than those in autumn, but it was in contrary in days from blooming to seed harvest. There were more branches per plant growing in spring, and the largest number of pods emerged in the sowing date of July 25 to 30. The highest seed yield were gained in the sowing date of July 20 to 30 for SG259, or Mar. 3 and July 25 for Provider. Seed quality of the two cultivars was better in the sowing date of July 20 to 30 than that of any other sowing dates. Based on the present experiment, we suggested that seed of dwarf bean be propagated in autumn, and sowing date be around July 25 in Hangzhou.
