Abstract: Kostelezkya virginica,an important economic plant with strong saline tolerance,was tested to better understand the effects of nitrogen additions on biomass characteristics and their relationship to K. virginica seedlings undergoing salt stress. Using completely random design,seedlings with 3-4 leaves were exposed for 35 d to treatments of 50,150,and 250 mmolL-1 NaCl and treatments of 50,150,and 250 mmolL-1 NaCl + 15 mmolL-1 NH4NO3 with 5 replications. Results showed that N addition significantly increased stem heights (P<0.05),but did not affect axial root length. For 50 mmolL-1 NaCl + 15 mmolL-1 NH4NO3,the average stem height was 26.1 cm,but without N it was 18.9 cm;and with N the average axial root diameter was 9.2 mm,but without N it was 6.8 mm. Additionally,leaf-weight ratios increased significantly (P<0.05) with N addition. Using 250 mmolL-1 NaCl + 15 mmolL-1 NH4NO3,leaf-weight ratios were 0.25 gg-1,but without N they were 0.14 gg-1. Root-weight ratios and root-to-shoot ratios significantly decreased (P<0.05) with N additions. Also,N inhibited fine root growth;whereas it promoted leaf growth. Finally,N significantly strengthened (P<0.05) the relationship between root mass and leaf mass. This could be helpful for utilization and allocation of N in K. virginica seedlings.[Ch,1 fig. 3 tab. 10 ref.]
