A New Possibility How to Evaluate the Level of Drought Stress in Plants for the Assurance of Landscape Plantings Prosperity
Original language description
More and more frequent drought spells increase plant mortality, complicate the growth of landscape plantings and impair their aesthetic impression in recreation areas. Improper handling and desiccation of plants before their planting out usually worsen the situation. The aim of this study was to determine the plant survival rate and the growth of plants stressed by desiccation, and to test a possible new method for the evaluation of water losses in plants. Bare-rooted plants of European beech were analysed in 2015, 2016 and 2017. The plants were exposed to desiccation for 0-6 hours and the loss of fine roots weight induced by intentional heat attack was measured before their planting out. Results showed that plants unstressed by desiccation reached the lowest mortality after the first growing season, especially in cases when a drought spell followed their planting out. Poor growth was observed only in surviving plants stressed by desiccation longer than ca 4.5 hours. The shorter was the period of plant desiccation, the faster was the decrease of the weight of fine roots due to the constant heat attack. Limit values are specific for individual species and are influenced by weather after planting out and during the growing season.
