Abstract:
Plant cultivars with high phosphorus efficiency adapt to P stress environment easily.Previous studies have focused on the mechanism of rice and wheat’s adaptation to low P stress.But effect of low phosphorus stress on activities of cell defense enzymes of different P efficient soybean is less documented.Therefore，pot experiments were conducted in 2006 year，with P high efficient soybean Kenjian 27 and P low efficient soybean Fengshou 25 as materials，to determine effect of low phosphorus stress on activities of cell defense enzymes of different P efficient soybean.The genotypic differences in P uptake efficiency of two soybean varieties were studied under controlled phosphorus(P) nutrition status，endosmosis permeability，superoxide dismutase(SOD)，peroxide enzyme(POD) activity，catalase enzyme(CAT) activity，and malondiaidehyde(MDA) content of different genotypic soybean growth period were investigated in nutrient solution culture.The difference of activities of cell defense enzymes was not significant under sufficient phosphorus supply.Under low phosphorus stress，endosmosis permeability of Fengshou 25 sharply increased，with conductivity and MDA content increased 41.01% and 23.43%，and activities of cell defense enzymes reduced obviously，with activities of SOD，POD and CAT decreased 12.52%，24.16%，and 31.75%，respectively；while for Kenjian 27，endosmosis permeability increased slightly and activities of cell defense enzymes were slightly reduced either.Results suggest that phosphorus high efficient soybean Kenjian 27 could make full use of phosphorus，improve activity of cell defense enzymes，depress bringing speed of O 2，reduce endosmosis permeability.
