pH值对绿豆种子萌发和幼苗生长的影响
Effects of applying different pH values on mung bean seed germination and seedlings growth
摘要
Abstract
This research investigated the effects of applying different pH values and determining the pH soaking time on mung bean seed germination and seedlings growth in order to provide basis for reducing soil acidity stress by scientifically raising seedlings in Southern China bean planting aren. [Method ]The experiment was designed with 5 different degrees of pH values and 2 soaking times. The seed germination and seedling growth of mung bean were observed. [ResultjThe results showed that the germination speed was the fastest out of all treatments when the pH level was 7.5; under this pH level, the most numerous seedling germination was also observed. Two days after the seeds were soaked in pH 7.5 solutions for 6 and 12 hrs, the germination rate was 87.5% and 92.5%, respectively. On the other hand, four days after seeding, the tallest seedling plant height were measured after the seeds were soaked for 6 and 12 hrs under the pH solution of 7.5 and 7.0, respectively. For all seeds soaked for 6 and 12 hrs under pH level 6.5 and pH level 7.0, respectively, their seedlings showed the highest fresh weight, while those soaked in pH level 8.0 showed the heaviest dry seedling weight. [Conclusion]The optimal pH value for soaking mung bean seeds should be between 7.0-7.5 to achieve the best mung bean germination and seedling growth in Hezhou districts of Cuangxi.关键词
