To explore the differences of the shapes of seeds and germination characters of Alisma plantago-aquatica.
The seeds were collected from four regions in Sichuan province, characters of the seeds' appearance were observed. The purification, weights per thousand seeds, content of moisture, seed vigor and different germination rates of A. plantago-aquatica were measured. The germination rates of the seeds were determined under different temperature treatments.
It was markedly varied in shapes of the seeds, rates of germination and all quality characters of the four local species. The seeds from Pengshan showed the best quality, the weights per thousand, the seed vigor and germination rate were 0.4308 g, 6% and 82%, respectively, and the size of the seed, its width and length were 1.882, 1.455 mm, respectively. The length was positively correlated with the width, and so did the weights per thousand seeds with the seed vigor and germination rates. The rate of seed vigor was positively correlated with the rate of germination. Results indicated that temperature had affected the germination of the seed.
The seed from Pengshan was the best. The result of this study provides scientific evidences for identification, growth and cultivation of A. plantago-aquatica.
探讨泽泻种子形态及萌发特性的差异。
采集四川省4个地区的泽泻种子，观察种子外观特征，测定种子净度、千粒重、含水量、种子活力及不同发芽率，测定不同温度处理下种子的发芽率。
4个产地的泽泻种子在形态、发芽率及各项品质性状上均有显著差异。彭山的种子品质最佳，千粒重、种子活力及发芽率分别为0.4308 g、6%和82%，种子大小、宽度和长度分别为1.882、1.455 mm。种子长度与宽度呈正相关，千粒重与种子活力及发芽率也呈正相关。种子活力与发芽率呈正相关。结果表明温度对种子萌发有影响。
彭山的种子最佳。本研究结果为泽泻的鉴定、生长及栽培提供了科学依据。
