冷季型草坪草种发芽试验

Germination Test on the Seeds of Cool-season Lawn Grass

对长春市8种(品种)主要冷季型草坪草种种子发芽率进行了测定,结果表明,8个草种(品种)发芽率为14%～94.0%,发芽势为4.0%～89.0%,其中"匍匐"紫羊茅、草地雀麦、剪股颖和冰草4个草种(品种)发芽早,发芽率和发芽势高,可优先选用,其余种(品种)发芽晚,发芽率和发芽势都较低,利用时应注意播量、种子处理和播种与播后管理。

Germination experiments were carried out with the seeds of 8 kinds of cool-season grass, such as Festuca rubra, Meadow bromegrass and Agrostis matsumurae, etc. The result showed that germina- tion rate of 8 kinds of grass species seeds ranged from 14% to 94% and germination potential ranging from 4.0 % to 89 %. Chewings rescue, meadow bromegrass, bent grass and wheatgrass germinated ear- lier with higher germination rates and germination potential. They could be prioritized for application.
