在Modesto 地区夏播条件下莲花某些遗传特性的表现

1985年7月3日至8月15日,在美国加利福尼亚州Modesto市太平洋企业公司莲园播种168组莲花种子约1000粒,保存568株苗,有35个组合的56株苗当年开了花,其中部分植株从播种到开花只需30至35天。绝大多数的植株在霜冻期来临之前都能自然结束其年生长期,但有一部分则不能。后者继续旺盛生长,直到霜期到来时叶片被冻死。这些现象表明,莲花的不同遗传类型之间,存在着对日照和温度的不同反应。

THE EXPRESSION OF SOME CHARACTERS ON LOTUS UNDER THE CONDITION OF SUMMER-SOWING IN MODESTO, CALIFORNIA, UNITED STATES

From July 3 to August 15, 1985, 168 groups of lotus, about one thousand seeds were sowed in the lotus garden in Modesto, California, United States. A total of 580 plants survived. 56 plants included 35 groups had bloomed in the same year and some of them came into squaring period only 30 to 35 days after sowing. Most plants end their growth period naturally before forsty season but some can't, the latter grow vigorously and their leaves are frozen when the forsty season come. These phenomena show that there are different responses to the sunlight and the temperature among genotypes of lotus.
