摘要
采用染色全过程观察和正交试验方法研究了TTC浓度、温度和染色时间对毛竹种子生活力的影响,探讨毛竹种子生活力测定的最佳条件。结果表明:四唑染色法能够很好地检测毛竹种子生活力水平,估测种子的潜在发芽能力。TTC浓度、温度和染色时间在生活力测定中存在一定的线性关系。试验表明,25℃下浸种48h待种子完全吸涨后,于30～35℃黑暗条件下、TTC浓度0.5%,染色3～4h为毛竹种子生活力测定的最佳条件。
To find the optimum conditions for testing seed viabilities of Phyllostachys edulis, TTC concentration, dyeing temperature and dyeing time were tested by dyeing process observation and orthogonal design（four levels in each of three factors）. The results showed that TTC methods could test seed viability level.effectively and appraise potential germination ability of Phyllostachys edulis. There existed linear relationship among solution concentration, dyeing temperature and dyeing time. This paper proposed that after full imbibition treatment by dipping in water for 48 hours at 25℃, 0.5% of TTC concentration, 30-35℃ of temperature and 3-4 h of dyeing time in darkness could be the best condition for Phyllostachys edulis seed viability testing.
