Abstract:
Under culture condition，two soybean varieties with different potassium (K) efficiency were selected to evaluate potassium absorb and use efficiency at two K levels by comparing the plant dry weights，potassium contents and accumulation in plants.The results showed that the relative dry weight of efficient variety was much more than that of inefficient variety.Distribution of K accumulated by plant in high efficient variety was well proportioned，and K contents in root and leaf were higher than those of inefficient variety in low-K stress，which showed the characteristic of effective absorbing and using potassium for efficient variety.But potassium absorbed by inefficient variety enriched in stem，which showed that transportation of potassium in plant was blocked.So the transportation and assimilation was key for difference of potassium efficiency in plants.
