摘要
研究了 4个番茄品种经飞船搭载后 ,番茄种子的发芽、植株生长、果实和抗病性的影响。结果表明 :搭载番茄种子的发芽率和发芽势有一定的变化 ,这种变化随品种而异。番茄种子经搭载处理后 ,其平均初花期推迟 0 7～ 5 4d ,且株间变异增加 ;植株有矮化的趋势。空间条件对番茄第一花序节位、花序间隔节位、小花数、座果率及果实大小有一定的影响。此外还发现在叶形。
The seeds of four tomato cultivars were traveled in Shenzhou No. 4 airship and the variations of seed germination and plant growth were studied. The results showed that seed germinating ability changed after the space shuttle carrying treatment, but the changes varied with cultivars. The first flower opening date was delayed 0 7～5 4 days and plant height was shorter than that of the control. The differences between individual plants were somewhat large. Some effects of space treatment on the position of the first inflorescence formation, leaf interval between inflorescences and the fruit setting ability were measured. Moreover, some changes in the leaf shape and fruit color were observed in some SP1 cultivars.
