This study shows that Mosla hangchowensis seeds were dormancy during winter.The temperature ranges of germination were between 10℃ and 35℃.The highest percent germination appeared in 20℃.The percent germination in changing temperature was not higher than that in constant temperature.Therefore Mosla hangchowensis could only germinate in spring.Under full light or dark conditions, the percent germination was 64% of that under the optimal conditions.The germination of upper layer seed chosen by water was only 7%, while that of the lower layer seed could reach 60%.However, percentage of seed mass of the lower layer in all seeds was only 32.6%.This means the main reason of the low percent germination could be the low quality of seed.The percent germination was correlated to kilo grain weight, unit weight in gas medium and electric conductance significantly ( P <0.05 or P <0.01).It was also correlated to the habitat of the maternal plants in a certain degree.When the maternal plant was grown under the light of 40%~100%, the mean percent germination of seeds was 24.6%.When the light was below 40%, the percent germination decreased.The percent germination of seeds of all populations was lower than 35%, showing that low percent germination was common problem to all of the populations of Mosla hangchowensis .

本文研究了我国特有的、分布区极狭窄的1年生草本植物——杭州石荠(Moslahangchowen-sis)种子萌发的生理生态学特性。结果表明:杭州石荠种子冬天休眠,早春开始萌发;萌发的温度范围是10~35℃,20℃时萌发率最高,因此其萌发的季节仅限于春季;变温处理的萌发率不高于恒温处理;全日照和黑暗条件使萌发率比最适条件的萌发率降低36%;水选上层种子的萌发率仅为7%,水选下层种子萌发率可达60%,但水选下层种子在全部种子中仅占32.6%,说明种子质量差可能是其萌发率低的重要原因。萌发率与千粒重、气介容重及电导率有显著相关;与母株生境也有一定关系,40%日照下母株所产种子的平均萌发率为24.6%,40%日照以下母株所产种子的萌发率降低;不同地区种群种子萌发率均低于35%。种子萌发率低是杭州石荠各个种群存在的共同问题。

The effects of population density of Mosla hangchowensis was studied. The results showed: (1)In the growing season, its mortality rate depended on its population density of M.hangchowensis. The optimal density of M.hangchowensis was 200~1000 individuals/m 2. (2)The relationships of the plant height or number of flowers bloomed and the dates fitted the Logistic function. (3)In the growing season ,about 60% of individuals at a high density can complete their life cycle, whereas, 85% at a low density can do. Most...

The effects of population density of Mosla hangchowensis was studied. The results showed: (1)In the growing season, its mortality rate depended on its population density of M.hangchowensis. The optimal density of M.hangchowensis was 200~1000 individuals/m 2. (2)The relationships of the plant height or number of flowers bloomed and the dates fitted the Logistic function. (3)In the growing season ,about 60% of individuals at a high density can complete their life cycle, whereas, 85% at a low density can do. Most of morphological and reproductive traits were density dependent.

本文研究了我国特有、分布区极狭窄的一年生草本植物———杭州石荠苎(Moslahangchowensis)种群的密度制约规律。结果表明:在生长季内,种群的死亡率与密度密切相关。种群的最适密度为200~1000株/m2左右。不同密度种群的平均株高、开花数等性状随时间的动态关系均符合“logistic”模型。高密度种群中60%左右的个体能完成生活史;低密度种群中80%以上的个体能完成生活史。种群密度较高制约杭州石荠苎的植株形态和繁殖投资
