前言目前,国际上虽已有一个为种子工作者所接受的有关种子活力的统一定义和一些测定方法,但至今有关种子活力测定方法的研究在国内则刚开始不久,并且多局限于容易发芽和发芽时间短的蔬菜和农作物的种子,而对于难发芽、发芽时间长的林木种子活力测定方法的研究则甚少。为了摸索出测定林木种子活力比较好的方法,我们对西北黄土高原主要造林树种(油松)的种子活力,进行了测定方法的探讨,现将结果总结如下:
Foreword At present, although there is a unified definition of seed vitality accepted by seed workers in the world and some measurement methods, so far the research on seed vigor determination method has just begun in China and is mostly limited to germination and Short germination time of vegetables and crops of seeds, and for difficult to germinate, germination time forest seed vigor determination method is poorly studied. In order to find out the method to determine the vigor of tree seeds, we discussed the determination of the seed vigor of the main afforestation tree species (Pinus tabulaeformis) in Northwest Loess Plateau. The results are summarized as follows:
