Název v původním jazyce

Changes in ABA, osmotic potential and proteins in fully- expanded leaves of cold-hardened cereals

Popis výsledku v původním jazyce

Intact mature leaves provide a suitable model of non-expanding green tissues and we used them for studying physiological changes during cold hardening of winter cereals (2 wheat and 4 barley cultivars). The leaf area in the expanded leaf did not change in both hardened (3 oC) and control (16 oC) plants. The ratio of water weight : dry weight decreased significantly only under hardening conditions. This decrease was due to an increase in dry weight rather than a decrease in water content. The accumulation of dry weight was accompanied with decreasing of osmotic potential and increasing of frost hardiness during cold hardening. The content of ABA in expanded leaf fluctuated transiently in both control and hardened plants, but no significant change in theABA level was observed either in the hardened and control leaf or in the cultivars with different frost hardiness. Patterns of proteins were different in expanded and young (expanding) leaf during cold hardening. High-molecular weight so
