浓硫酸处理对黄河三角洲野大豆发芽效果的影响

The effect of concentrated sulfuric acid on germination of wild soybean in Yellow River Delta Area

在对黄河三角洲野大豆Glycine soja人工栽培的研究中,先进行了野大豆种子播种前处理方法的研究,破除其种皮硬实,提高发芽率。试验用98%浓硫酸浸泡加搅拌处理野大豆种子,设3,6,9,12 min及对照5个水平,并分别以滤纸和沙作为培养床进行发芽试验。结果表明,用浓硫酸浸泡加搅拌作用效果明显(P<0.05),其中处理时间为9 min发芽率和发芽势最佳,分别达到100%和99.33%,而不同培养床间发芽率和发芽势差异不显著(P>0.05)。

Before being planted artificially, the hard seed of wild soybean in Yellow River Delta Area must be treated to improve the germination rate. In treatment, the seeds were soaked in concentrated sulfuric acid and stirred for 3,6,9,12 and 0（control treatment） minutes, then put on filter paper and sands. The result showed that the influence of concentrated sulfuric acid on germination rate and germination force of wild soybean in Yellow River Delta Area is significant （P〈0.05）, but the difference between filter paper and sands is insignificant （P〉0.05）. The best result, that germination rate and germination force reached 100% and 99.33%, is obtained when the seeds were soaked in concentrated sulfuric acid and stirred for 9 minutes.
