| 摘 要： | 研究了在不同盐浓度条件下4种不同玉米品种的植株鲜重、根冠比、株高及植株吸磷量的差异,并探讨了苗期性状与吸磷量的关系。试验结果表明,不同盐浓度及不同玉米品种间的植株鲜重、根冠比、株高、吸磷量均存在极显著差异,不同玉米品种的植株鲜重、株高与玉米吸磷量间呈极显著正相关,相关系数达0.748以上,而玉米植株的根冠比与吸磷量之间呈极显著负相关。

| Abstract: | With the NaCl Solution of different concentration, the differences among the fresh weight, root/shoot ratio, stem height, phosphorus uptake in the four different kinds of maize varieties were studied, and the relationship between the seedling traits and phosphorus uptake was discussed. The experimental results show that there was significant difference in the fresh weight, root/shoot ratio, stem height and phosphorus uptake among the different NaC1 concentration and different varieties of maize. And there was a significant positive correlation among the fresh weight, stem height and phosphorus uptake in the different varieties of maize, and the correlation coefficient was above 0.748, while there was a significant negative correlation between the root/shoot ratio and phosphorus uptake in the maize. |
