Conteúdo: |
The extent to which Eucalyptus camaldulensis trees, growing in very deep soil; and rooted cuttings in pots maintain their leaf water status under drought, and the significance of root activity and changes in leaf stomatal conductance to dehydration avoidance were studied. In the field, E camaldulensis maintained relatively high leaf water potentials even though they were not supplied with irrigation or rain for up to 58 days. Recently irrigated and droughted trees exhibited greater stomatal opening during the early moning and partial stomatal closure during the time of day when evaporative demand was hithin two weeks after irrigation, partial stomatal closure occured earlier in the day leaf conductances were lower during the afternoon than those of recently irrigated tress. The substantial dehydration avoidance of E. camaldulensis appeared to be partialy due to sensitive stomatal closure in response to drought, induced by either soil water depletion or high evaporative demand. Extraction of soil moisture progressively deeper in the soil profile also would have contributed to dehydration avoidance. |
