一.引言在農林园藝生产实践中,一般用发芽率来测定种子的生活力。但是,对休眠期长的或需要经过特殊处理後才能发芽的种子,就感到相当困难。所以很久以来,人们在不断的研究快速测定种子生活力的方法为播种、调运、交换种子等工作解决困难。Flemion(1936,1941,1948) I. Introduction Agricultural and forestry horticultural production practices, the germination rate is generally used to determine the viability of the seed. However, it is rather difficult for seedlings that have long dormant or need special treatment to germinate. Therefore, for a long time, people are constantly studying how to quickly measure the viability of seed to solve the problems of sowing, transporting and exchanging seeds. Flemion (1936, 1941, 1948)
