Název v původním jazyce

Relationship between abscisic acid content, dry weight and freezing tolerance in barley cv. Lunet

Popis výsledku v původním jazyce

The role of abscisic acid (ABA) in freezing tolerance induction of barley was studied using a number of approaches. First, the plants were hardened by cold at 3°C. Second, the endogenous ABA content was increased by means of three established methods: (i) rapid dehydration of detached, fully expanded second leaves; (ii) application of 20% polyethylene glycol 8000 (PEG) into the growth solution of plants; or (iii) 7.5x10-5 mol/L ABA supplement into the growth solution. Cold hardening of plants resulted in increased freezing tolerance; only some ABA content fluctuation was observed. The rapid dehydration of detached leaves resulted in an increase of ABA content but not in any significant increase in freezing tolerance. The increase of ABA content in theleaves of intact plants, either due to application of PEG or addition of exogenous ABA into the growth medium, led only to a moderate increase of freezing tolerance. Freezing tolerance of barley leaves could not simply be explained by ABA
