摘　　要：在不同氮(磷)浓度下,分析不同小麦基因型苗期的幼苗干重和根系干重,研究不同基因型小麦对氮磷反应的差异性。结果表明,在无氮(无磷)条件下,小麦基因型间幼苗干重和根系干重差异不显著;当氮浓度为0.05 mmol/L时,小麦基因型间幼苗干重差异不显著,根系干重差异达显著或极显著水平,当磷浓度为0.005 mmol/L时,小麦基因型间幼苗干重和根系干重均达显著或极显著水平;当氮和磷浓度分别达2.00和0.250 mmol/L时,小麦基因型间幼苗干重和根系干重差异显著或极显著。The seedling dry weight and root dry weight of different wheat genotypes were analyzed in different concentrations of nitrogen(phosphorus).At the same time,the variation in response of wheat genotypes to nitrogen and phosphorus were studied.The result suggested that the difference between wheat genotypes on seedling dry weight and root dry weight were insignificantly as the concentration of nitrogen(phosphorus)was 0 mmol/L.As the concentration of nitrogenis increased to 0.05 mmol/L,the variations of wheat genotypes on seedling dry weight were insignificantly,but the variations on root dry weight were significantly different at 0.05 and 0.01 probability level respectively.As the concentration of phosphorus increased to 0.005 mmol/L,the variations of wheat genotypes on seedling dry weight and root dry weight were significantly different at 0.05 and 0.01 probability level respectively.As the concentration of nitrogenis and phosphorus were 2.00 mmol/L and 0.250 mmol/L respectively,the variations of wheat genotypes on seedling dry weight and root dry weight were significantly different at 0.05 and 0.01 probability level respectively.
