摘要
种子活力研究工作目前已由简单的发芽生理指标深入到细胞器、酶及核酸代谢等研究中。Woodstock及傅家瑞等在论述种子活力及其生理生化基础时,都首先强调了细胞膜和细胞器的完整性及结构上的变化对活力的影响。至今,国内外已在花生、黑麦、意大利伞松,大豆,绿豆等种子的细胞超微结构变化方面作了不同程度的报道。
No. 244 and No. 5 open-pollinated seeds in primary seed orchard for Chinese fir (Cunning hamia lanceolata) grafting were used as the test material for studying the relationship between ultrastructural changes and seed vigour during germination. The result showed that No. 244 was high-vigour seed and No. 5 was low one. During germination of Chinese fir seeds, increase of number and rate of development of mitochondria (Mt), golgi body (GB) and rough endoplasmic reticulum (RER)etc. of the high-vigour seeds No. 244 were earlier and faster than that of the lower-vigour seeds No. 5, Resolution power, quantity of starch grain (ST) and quantity of liposome (L) were also more than low one. All these showed that there exist close relationship between changes of cell ultrastructural and seed vigour during germination of Chinese fir seeds.
