Abstract:
Soybean seedlings, which cultured for three internal phosphorus concentration, grown in solution culture for 5 weeks, were used to study the relationship between root character and P absorption. Results suggested internal P induced root growth.In the same internal P treetment, external P affected root length and which decreased with P further increase. Especially, on 3 week after P treated, root length of S2 and S3 increased separately 5.2% and 30.1%. Without P treatment, the effect of internal P on root surface obtained 5% significant level from 2nd week. However, treatment added P up to 5% significant level only on 4th and 5th week. At all harvest time, dry weight of biomass and P efficiency did not up to significant level, but when P efficiency was above 0.40, dry weight of biomass increased as P efficiency increased. The relationship between P efficiency and P content up to 1% significant level, P content decreased exponentially with P efficiency increased.
