ABSTRACT
<p><b>OBJECTIVE</b>To study the salt stress tolerance of Hongxinju, Huangju and F1 seedlings from orthogonal and reciprocal cross under different salt treatments. Grope for transmissibility of salt tolerance between parents and F1 seedlings, and relativity between flavone, chlorogenic acid contents and salt tolerance.</p><p><b>METHOD</b>The materials were put in 5 different concentrations of Hoagland nutrient solution (0, 40, 80, 120, 160 mmol x L(-1)) containing NaCl, keeping grads while raising the consistency of NaCl day by day. The injured leaf area per plant, proline, betaine, MDA, flavones and chlorogenic acid contents were measured and analyzed after treatment.</p><p><b>RESULT</b>As NaCl concentration was below 120 mmol x L(-1), the salt tolerance of Hongxinju was higher than that of Huangju, the salt tolerance of Hongxinju x Huangju higher than that of parents, the salt tolerance of Huangju x Hongxinju was at the level of parents. As NaCl concentration between 120 to 160 mmol x L(-1), the salt tolerance of Huangju was higher than that of Hongxinju, the salt tolerance of Huangju x Hongxinju higher than that of parents and the salt tolerance of Hongxinju x Huangju was at the level of parents.</p><p><b>CONCLUSION</b>Salt tolerance of F1 is more influenced by female parent, relativity showed between flavonoids, chlorogenic acid contents and salt tolerance.</p>
