种子是农林业生产中最基本的生产资料之一。有了优质种子,才能提高产量。国际上很早便把种子活力(Vigor)作为一个重要的品质指标。可是,种子活力的生理基础以及确切的含义,目前尚不十分清楚,很有必要作深入研究。 我们选用花生为试验材料,因春植花生留种在翌春播时发芽力一般低于秋植花生留种,尤其在早春不良气候条件下,差异更为显著,因而造成严重缺株。在表面现象上,种子活力表现的差异在于发芽力与幼苗生长势,而其内部生理反应包括代谢过程。酶活性以及亚细胞水平的微细结构与功能上。 我们将春植花生所留种子分别贮于相对湿度15％、32％、75％、90％的环境
Seeds are one of the most basic means of production in agriculture and forestry. With high-quality seeds, can we increase production. Vigor has long been used internationally as an important quality indicator. However, the physiological basis of the seed vitality and the exact meaning of the seed is not yet clear, it is necessary to make further study. We use peanut as the test material, because the spring planting peanut seed in the next spring sowing germination force is generally lower than the autumn planting peanut species, especially in early spring under adverse climatic conditions, the difference is more significant, resulting in serious lack of strains. On the surface, the difference in seed vigor lies in the germination power and seedling growth potential, while the internal physiological responses include metabolic processes. Enzyme activity and sub-cellular level of the fine structure and function. We will be planting seeds peanuts were stored in relative humidity 15%, 32%, 75%, 90% of the environment
