不同pH条件下镉对水稻幼苗生长的影响
Effects of Cadmium on the Growth of Rice Seedlings Under Different pH Conditions
摘要
Abstract
To investigate the effects of cadmium on the growth of rice seedlings under different pH conditions,taking Xiangyuezhan as the re-search materials,solution culture method was used to study the effects of cadmium stress on the growth of rice seedlings.The results showed that there were differences in the height,longest root length and total root number of rice seedlings soaked in different pH water and cadmium ion solutions,with the highest value at pH 9.Compared with water immersion,rice seedlings soaked in cadmium ion solution showed signifi-cant decrease in seedling height,longest root length,total number of roots and fresh weight per hundred plants.When the pH was 8 or 9,the photosynthetic pigments of rice seedlings soaked in both water and cadmium ion solution could reach the highest value.Different pH values could significantly affect the content of malondialdehyde in rice seedlings.When the pH value was 9,rice seedlings soaked in water had the highest content of malondialdehyde,while rice seedlings soaked in cadmium ion solution had the lowest content of malondialdehyde.This re-search revealed the coupling effect of pH and cadmium on the growth characteristics of rice seedlings,providing practical reference for rice production.关键词
