The temperature range of 10 ̄ 15 ℃was more suitable and 20℃ would be harmful to seed germination. Though the germination percentages ofPaeonis szechuanha Fang of four localities were only slightly different (60- 77 % ), there were great different in P. rockii T. Hong et. J. J. Li among the three different localities: the germination rate of seeds from Wenxan county, Gansu province was high to 76%, the others were only 12% and 4. 4% from Lueyang county, Shanxi province and Shennongjia county, Hubei Province, respectively. It is suggested that the seed germination characters were one of the important factors which had caused the endangered status of wild P. rockii T. Hong et. J. J. Li.

野生牡丹种子一般较小,而且不同产地之间形状、大小差异较大。其萌发特性与栽培牡丹相比也有较大差异:萌发期长达半年以上,且萌发温度在10~15℃为宜,超过20℃则明显不利于生根及上胚轴生长。四个不同分布地的四川牡丹种子萌发率较一致,均在60~77%之间。三个不同产地的紫斑牡丹种子萌发率则相差甚远,分布于甘肃文县的萌发率达76%,而分布于陕西略阳和湖北神农架的萌发率则分别只有12%和4.4%,出苗率则更低。本文认为紫斑牡丹的种子特性是其在自然界处于濒危状态的重要原因之一。

There are three species of wild rice,which are wild relatives of the cultivated rice and listed in endangered plant species in China . They are distributed in humid areas of tropical and subtropical regions in eight provinces of southern China. Recently, human disturbance and destruction of habitats have led to the extinction of a great number of populations,of which Oryza rufipogon Griff. is the most endangered species. In this paper,their biological and ecological characteristics were described and the plant communities were also studied. Meanwhile, the endangered status and the reasons of wild rice in China were discussed.

实种子外被刺状刚毛,种皮坚硬面厚实,吸水萌发极其困难,经测定,其种子结实率为65.9%,生活力为50.0%。发芽率仅有25%,如果种子长期处于温暖湿润的环境而不萌发,其生活力继续下降。由此可知,实的种子特性是其在自然状态下濒危的重要原因之一。
