[目的]探究万寿竹种子脱水过程中,发芽及部分抗逆生理指标的变化情况,为万寿竹种子贮藏及采收提供理论依据。[方法]利用室温硅胶干燥法获得45.90%、40.50%、38.07%、33.08%、27.26%、16.67%、14.63%7个含水量梯度的种子,以未干燥的种子(49.12%)为空白对照,分别测定各个含水量梯度种子的生活力、发芽率、电导率、CAT、SOD、POD、AsA-POD活性、MDA、可溶性蛋白质含量。[结果]种子含水量保持在33.08%以上时,能保持较高的生活力、发芽率,当含水量下降到33.08%以下时,种子发芽率和生活力开始显著下降。[结论]万寿竹种子不耐脱水,属于顽拗性种子,贮藏时含水量应保持在33.08%以上。
[Objective] The purpose of the research was to investigate the changes of sprouting and some stress-resistant physiological indexes during the dehydration process of Wanshou bamboo, and to provide a theoretical basis for the storage and harvesting of Wanshou bamboo seeds. [Method] Seeds with gradient of 45.90%, 40.50%, 38.07%, 33.08%, 27.26%, 16.67%, 14.63% were obtained by using silica gel drying method at room temperature. The seeds with non-dried seeds (49.12% The viability, germination rate, electrical conductivity, CAT, SOD, POD, AsA-POD activity, MDA and soluble protein content of each water content gradient seed were determined respectively. [Result] When seed moisture content was above 33.08%, higher viability and germination rate could be maintained. When the moisture content dropped below 33.08%, seed germination rate and viability began to decline significantly. [Conclusion] The seeds of Longevity bamboo were not resistant to dehydration and they were recalcitrant seeds. The water content in storage should be above 33.08%.
