Abstract
The Impact of Drought, Normal Watering and Substrate Saturation on the Morphological and Physiological Condition of Container Seedlings of Narrow-Leaved Ash (Fraxinus angustifolia Vahl)
Highlights
Narrow-leaved ash (Fraxinus angustifolia Vahl) is one of the most important tree species of lowland floodplain forests
During the substrate saturation treatment, a constant water level was retained in the bath with the containers so that the water was above the seedling root collars
The mean height increment of seedlings under normal watering conditions between 5 May 2015 and 15 July 2015 amounted to 48 mm (0-119 mm) and diameter increment amounted to 0.39 mm (0.00-1.31 mm)
Summary
Narrow-leaved ash (Fraxinus angustifolia Vahl) is one of the most important tree species of lowland floodplain forests. The basic ecological factors that determine the occurrence of this forest tree species are micro-depressions in which water is retained after frequent flooding, and clayey alluvial soil which prevents water drainage. Due to these factors, forests of narrow-leaved. Narrow-leaved ash (Fraxinus angustifolia Vahl) is one of the most important tree species of lowland floodplain forests in the Republic of Croatia. Our study aims to determine the morphological and physiological characteristics of seedlings of narrow-leaved ash after 72 days of drought, normal watering and substrate saturation. Seedlings saturated with water for 72 days showed a better morphological-physiological status than the seedlings that received normal quantities of water
