Biologic characteristic on the nutritional stress in the Dongxiang wild rice were surveyed with the two populations Dongtang(DT)and Dongtangxice(DTXC),a variety tolerant to phosphorus defeciency Dalidao(DLD) and another variety sensitive to phosphorus defeciency Xinsanbaili(XSBL) by sandy culture and soil culture.The results of sandy culture showed that the dry weight of shoot and yield of biomass of DT and DTXC decreased under low-N,low-P,low-K stress.the ratio of shoot to root increased more significantly and it was more obviously under low-N stress.The results of soil culture showed that the dynamics of plant height and tillering under low-N were basically similar to those of no fertilizer treatment in all varieties.Under low-N,low-P and low-K stresses the tillering numbers of DLD and XSBL had a decreasing stage,but those of DT and DTXC populations basically kept steady.Compared to full fertilizer treatment,traits of dry weight of leaf,root and stem-sheath of DT were significantly different,and traits of length of flag leaf,dry weight of leaf,stem and yield of biomass of DTXC were significantly different under P-deficiency condition respectively,and other traits were insignificantly different.Other 11 traits of DT were insignificantly different barring dry weight of leaf and root,and other 11 traits of DTXC were insignificantly different barring density of spikelet setting and weight of panicle respectively under K-deficiency condition.So it preliminarily indicated DT and DTXC of Dongxiang wild rice were no tolerant to low-N,and had more different tolerant ability to low-P and low-K stresses.
