用30%聚乙二醇和3%硝酸钾溶液分别对番茄种子进行引发处理,引发处理提高了种子的发芽速度和整齐度。聚乙二醇引发处理的种子在室温下保存5.5年依然保持明显的引发效果,没有表现出比未引发的对照种子衰老快的趋势。对引发种子进行加速老化试验结果表明,聚乙二醇引发种子比未引 The seeds of tomato were primed with 30% polyethylene glycol and 3% potassium nitrate solution respectively, and the priming treatment increased the germination speed and uniformity of the seeds. Polyethylene glycol-primed seeds remained markedly primed for 5.5 years at room temperature and did not show a faster senescence than non-primed control seeds. Accelerated aging tests on seed initiation showed that the PEG-initiated seed ratio was not induced
