Black locust (Robinia pseudoacaciaL.) is a drought-tolerant fast growing tree, which could be an alternative to the more common tree species used in short-rotation coppice on marginal land. The plasticity of black locust in the form of ecophysiological and morphological adaptations to drought is an important precondition for its successful growth in such areas. However, adaptation to drought stress is detrimental to primary production. Furthermore, the soil water availability condition of the initial stage of development may have an impact on the tree resilience. We aimed to investigate the effect of drought stress applied during the resprouting on the drought tolerance of the plant, by examining the black locust growth patterns. We exposed young trees in lysimeters to different cycles of drought. The drought memory affected the plant growth performance and its drought tolerance: the plants resprouting under drought conditions were more drought tolerant than the well-watered ones. Black locust tolerates drastic soil water availability variations without altering its water use efficiency (2.57 g L−1), evaluated under drought stress. Due to its constant water use efficiency and the high phenotypic plasticity, black locust could become an important species to be cultivated on marginal land.

CO2 gas exchange, transpiration, stomatal conductance, water use efficiency and chlorophyll content were investigated at the leaves of three species of the family Plantaginaceae: Plantago maritima L., Plantago subpolaris Andrejev and Plantago schrenkii C.Koch under natural conditions of the habitat on high and low tide areas of the White Sea’ coasts. The high rate of photosynthesis at saturating CO2 (PNmax) at P. maritima (85.0±4.8 μmol m-2 s-1), as compared to P. subpolaris and P. schrenkii (45.2± 7.5 and 36.9±3.2 μmol m-2 s-1) was caused by high activity of ribulose-1,5-bisphoshate carboxylase/oxygenase (RuBPCO), the rate of electron transport, the rate of triose phosphate utilization, TPU), as well as high efficiency of carboxylation. The rates of photosynthesis at ambient concentration of CO2 (PN) at P. maritima were 1.4 and 1.7 times higher compared to P. subpolaris and P. schrenkii. Plants of P. schrenkii are characterized by lower values of stomatal conductance and water use efficiency compared to P. maritima and P. subpolaris. In natural habitat, the limiting factor of CO2 assimilation P. subpolaris is the rate of photosynthetic electron transport, the activity of RuBPCO in P. schrenkii.
