美国农业研究中心的科学家伍德斯特克建议用重氢来鉴别大豆种子的好环。试验是将商品大豆种子用浓度为0.25％、75％和100和重水在温度25℃条件下浸泡18小时,然后移到用普通水浸湿的纸巾上。结果表明,高活力种子的发芽和生长不受任何一种重水浓度的影响;低活力种子,在100％的重水中有60％不发芽,在75％的重水中发芽但生长不良。由此可见,大豆种子对重氢的反应明 Woodstack, a scientist at the American Agricultural Research Center, recommends using heavy hydrogen to identify good rings in soybean seeds. The test was to soak commercial soybean seeds at a concentration of 0.25%, 75% and 100%, and heavy water at a temperature of 25 ° C for 18 hours and then onto a paper towel soaked with normal water. The results showed that germination and growth of highly viable seeds were not affected by any of the heavy water concentrations; low-vigor seeds did not germinate in 60% of 100% heavy water but germinated in 75% of heavy water but did not grow well. Thus, the reaction of soybean seeds to deuterium shows
