Abstract:
Solution culture experiment with soybean was made to study the effect of nitrogen forms on theroot morphology and proton extrusion from roots. The results showed that there were significant differ-ences between the effects of nitrogen forms and soybean root morphology. NO 3 -N and NH 4 NO 3 -N inducedroot surfacearea increased;NH?4+?-N inhibited root grow th , however, the root morphology of N 2 -fixationtreatment nearly did not have changes, except tips of root increased with time. The H+extrusion fromroot indicated that NH 4+ -N increased H +extrusion, but the poison symptom when NH 4+-N was an nitro-gen source and amount of H+extrusion from NH 4 NO 3 -N treatment was in the middle of NO 3 -N 、NH 4+ -Nand NH 4 NO 3 -N. At early stage , N 2 -fixation treatment had low nitrogenase activity so that inhibited plantgrow th and low biomass.
