Abstract
During the first stage of hardening of winter rape plants (Brassica napus L. var. oleifera L., cv. Górczański), marked increase of ATP content in leaves was observed. Lowering the temperature from 5 to 0 C (the second stage of hardening) had no further effect on ATP content. In roots, not capable of hardening, pronounced decrease of ATP content was noted after prolonged exposure to cold. It was found that increased ATP content and higher energy charge in cold-treated leaves were due to light and dark processes.
摘要
在冬油菜（甘蓝型油菜，油用甘蓝变种，戈恰申斯基品种）硬化的第一阶段，观察到叶片中 ATP 含量显著增加。将温度从 5°C 降低到 0°C（硬化的第二阶段）对 ATP 含量没有进一步的影响。在不能硬化的根部，经过长时间的寒冷处理后，发现 ATP 含量明显下降。研究发现，低温处理叶片中 ATP 含量增加和能量电荷升高归因于光合作用的光反应和暗反应。
