野生地肤种子发芽特性的研究

Study on the Seeds'gremination of Kochia Scoparia(L.) Schrad

为探究野生地肤的发芽特性,本试验对其休眠期、浸种时间、催芽温度等多项指标进行了测定。结果表明:野生地肤的休眠期为一个月左右,属于休眠期短的种子类型;浸种时间和催芽温度最佳处理组合为4h、20℃;在温度20℃、浸种4h的条件下,泠藏的野生地肤种子发芽率没有变化,但是发芽势增加,常温下贮藏发芽率、发芽势都有所增加;三种不同果皮颜色类型的种子的发芽率、发芽势以褐色为最好,其次是红色的,最差的是绿色的种子。

With the aim of finding the seeds germinalion of Belvedere Fruit（ Kochia scoparia（ L. ） Sehrad. ） ,some indexes ,fox example dormant period,the budding temperature, the souking seeds time . and so on,are measured in this experiment. The dormant period is around one month, belonging to short dormant period seed type ; The soaking seeds time and the budding temperature is 4h, 20℃ ; In the temperature of 20℃, after being soaked for 4h, seed - germination percentage of the seeds in cold storage does not have change, but the germination tendency increases; Under the normal temperature, the seed - germination percentage, the germination tendency all have the increase; Among the three kinds of different peel color, the brown type has the best seed - germination percentage and the germination tendency, next is red, worst is the green seed.
