摘要
对十字花科短命植物抱茎独行菜的生长节律、开花结实特性进行观测,并计算其生殖配置。抱茎独行菜的整个生活史为60d左右,生殖时间早,持续时间相对较长,占整个生活史的3/4。生殖配置为50.36%,高于一次结实的草本植物的生殖投入。高的生殖投入与荒漠环境及短的生长周期有关。
The growth regular and floral expression and fruitification of ephemeral plant of Lepidium perfoliatum L. were observed, and reproductive assign was calculated.Their lifehistory is 60days.Reproductive age is younger,and reproductive period is longer.It takes three fourths of lifecircle.Reproductive assign is 50.36%, it's higher than that of monocarpic herbaceous plants.High reproductive investment are correlated with desert environment and short lifehistory.
