Abstract
The investigations were designed to test the sensitivity of different organs of Phaseolus vulgaris L. to chilling. Water relations parameters, leaf diffusion resistance and abscisic acid accumulation in roots and leaves were monitored during 72 hrs of chilling treatments, in primary and trifoliate seedling stage. During the first 20-30 hrs of chilling, bean seedlings suffered a marked water stress, subsequently plants were rehydrated and regained turgor. In primary seedling stage the water unbalance lasted for a longer period, compared with trifoliate seedling stage. ABA levels in trifoliate leaves started to rise earlier than in primary leaves and reached higher values. In trifoliate seedling stage, root ABA content was 3-5 times higher than in the primary ones. In both stages considered, root ABA levels increased during chilling but the rise in root ABA did not precede either stomatal closure or ABA accumulation in the leaves. ABA involvement in ameliorating chilling-induced water stress is discussed.
