摘要
[目的]研究不同土壤pH对普通野生稻生理特性的影响。[方法]以雁山普通野生稻为试验材料,通过盆栽试验设置不同土壤pH栽培,比较不同pH下普通野生稻的生理特性变化。[结果]在pH为6.8的中性条件下,普通野生稻叶片叶绿素相对含量和可溶性糖含量最高,脯氨酸含量和MDA含量维持最低水平,且CAT和POD活性均为最高。[结论]雁山普通野生稻对中性偏碱环境的适应性较强,适宜的环境pH范围为6.0～7.4。
[Objective] The research aimed to study the effects of soil pH value on physiolovical characteristics of Oryza rufipogon Griff.[Method] Using O.rufipogon as test material,the physiolovical characteristics of O.rufipogon were analyzed through pot experiment under different soil pH value culture.[Result] The chlorophyll content and soluble sugar content were highest,while the proline content and MDA were the lowest at pH=6.8.CAT and POD showed strongest activity at pH=6.8.[Conclusion]O.rufipogon adapt to the pH range form 6.0 to 7.4.
