加速老化试验是种子活力测定方法逆境试验中的一类,目前在国内外都得到了广泛的应用。关于加速老化方法研究的文章很多,不同的试验者所采用的方法也不尽相同。但足不管方法如何不同,都是根据Roderts(1972)提出的概念,即贮藏期间种子处于高温高湿的条件下,会逐渐老化,最后丧失生活力所进行的。本文就是要对一般加速老化方法、热水加速老化法、甲醇加速老化法、人工变质试验等不同的种子加速老化方法进行讨论。一、一般加速老化方法 (一)方法此种方法又分快速人工老化和缓慢人工老化。快速人工老化是用40～42℃温度、100%相对温度处理1～10天,一般为4天,适宜的老化天数可根
Accelerated weathering test is a kind of seed testing method in the adversity test. At present, it has been widely used both at home and abroad. There are many articles on the research of accelerated aging methods, and the methods used by different experimenters are different. However, regardless of how the method is different, it is based on the concept put forward by Roderts (1972) that the seed will age and eventually lose its viability under the conditions of high temperature and humidity during storage. This article is to discuss the accelerated aging methods, such as general accelerated aging method, hot water accelerated aging method, methanol accelerated aging method and artificial deterioration test. First, the general method of accelerated aging (A) Method This method is divided into rapid artificial aging and slow artificial aging. Rapid artificial aging is 40 ~ 42 ℃ temperature, 100% relative temperature for 1 to 10 days, usually 4 days, the appropriate number of days of aging root
