温度和PEG浓度对金荞麦种子萌发的效应

Effects of Temperature and PEG Consistency on Germination of Fagopyrum Dibotrys Seeds

研究了不同发芽温度和PEG浓度对金荞麦种子发芽的影响,主要测定了发芽势、发芽率和发芽指数三项重要指标。结果表明,不同发芽温度对金荞麦种子以上三项指标的影响均达到了显著差异,不同PEG浓度对金荞麦种子发芽率的影响达到了显著差异,而对发芽势和发芽指数没有显著差异。其中发芽温度15℃和5%的PEG浓度是金荞麦种子发芽的较适宜温度和PEG浓度。

The study shows the influence of different sprouting temperatures and PEG consistencies on germination of Fagopyrum dibotrys seeds. We mainly investigate three significant indexes, which are sprouting potentialities, sprouting rate and sprouting index. The result shows that different sprouting temperatures notably influence the indexes above. Different PEG consistencies notably influence the prouting rate, but not notably influence the prouting petentialities and sprouting index. Among them the sprouting temperature of 15℃ and PEG consistency of 5% are the most desirable sprouting temperature and PEG consistency.
