幼根、幼苗的活力状况,认为是种子活力的一个重要的、全面的综合表现,已为众多的试验所证实。我们自1982年冬至1985年连续3年,用杉木嫁接初级种子园单亲子代为材料进行了试验。结果田间幼苗重量与种子活力相关密切。为深入了解影响幼苗重量的种子的作用,必须对种子的生理生化基础作进一步的研究。 TZ法已被国际上用来作为鉴别种子生命力和测定种子活力的简易可行的测定方法。在杉木上应用TZ法来比较各单亲子代间种子活力的大小以及它们之间的相互关系,尚未见报道。我们做了一系列的测定,现将试验结果整理如下。
The vigor of young roots and seedlings is considered to be an important and comprehensive comprehensive performance of seed vitality and has been confirmed by numerous experiments. From the winter of 1982 to the year of 1985 for three years in a row, we conducted the experiment with the single-parent seedlings of Chinese fir grafted primary seed orchard. Results Field seedling weight and seed vitality are closely related. In order to gain a deeper understanding of the role of seed that affects the seedling weight, the physiological and biochemical basis of the seed must be further studied. The TZ method has been used internationally as a simple and viable method of identifying seed vitality and determining seed viability. The application of the TZ method on Chinese fir to compare the seed vigor among single parents and the correlation between them has not been reported yet. We made a series of measurements, the test results are summarized below.
