摘要
无论在光下和暗中长叶红沙种子都能萌发，萌发率无显著差异；种子萌发的适宜温度为20-25℃。温度高于25℃时，温度越高，萌发率越低；浓度低于100mmol．L^-1的NaCl对种子萌发的影响不大，但高于150mmol．L^-1时，NaCl下的萌发率随着NaCl浓度的增高而下降，直至0；NaCl溶液处理9d的未萌发种子转移至蒸馏水中后，经高浓度NaCl胁迫（小于500mmol.L^-1）处理的种子萌发恢复率较高。
No difference was found in the seed germination of Reaumuria trigyna in light and darkness. The optimal temperature for germination was 20-25℃. When the temperature was over 25 ℃, the germination percentages decreased. NaCl at concentration below 100 mmol.L^-1 had no effect on seed germination. When NaCl concentration was over 150 mmol.L^-1, the seed germination obviously decreased until 0. After treatment with NaCl solution for 9 d, then transferred in distilled water, germination recovery percentages of seed treated with high concentration of NaCl （〈500 mmol.L^-1） was higher.
