New knowledge was obtained about the relationship between the parameters of photosynthesis, transpiration and dark respiration in alfalfa varieties of various ecological and geographical origin at the early stages of ontogenesis, depending on the intensity of abiotic stressors: salinity conditions (0.3 M NaCl) and various intensity of photosynthetically active radiation (from 0 to 1500 mol*m−2 s−1). Purpose of the work: assessment of the potential resistance of alfalfa varieties and breeding samples to abiotic stressors for breeding for adaptability. To determine the parameters of gas exchange of cotyledon leaves of alfalfa varieties, a portable system for measuring plant gas exchange LI-6800, LI-COR, USA was used. The results of a two-way ANOVA analysis of the influence of the salinity factor and illumination conditions on the resulting signs of gas exchange parameters showed that the proportion of the influence of the genotype of breeding samples on the studied effective signs associated with the operation of the photosynthetic apparatus (the intensity of CO2 assimilation and the intercellular concentration of CO2) ranged from 7.25 to 21.35%; associated with water exchange parameters (transpiration and stomatal conductivity for H2O) varied from 18.80 to 19.84%. Selected breeding samples of alfalfa with high resistance of the photosynthetic apparatus to abiotic stressors.

The large-flowered sweetvetch (Hedysarum grandiflorum Pall.) is a perennial beautiful-flowering plant with a narrow ecological amplitude, promising for introduction and cultivation. Under controlled conditions using the LI-6800 instrument, LI-COR, USA, the dynamics of indicators of photosynthesis intensity, transpiration and accompanying physiological processes related to gas exchange in H. grandiflorum seedling leaves under different light levels (1500, 1000, 500, 200, 100, 50, 0 µM/m2/s) in saline conditions was studied. It has been established that photosynthetic apparatus of H. grandiflorum seedlings adapts well enough to saline conditions and significant photosynthesis suppression by 17.4 % is observed only at PAR level of 300 µM/m²/s¹. At the same time, a significant decrease in the rate of water evaporation by the surface of cotyledon leaves under the influence of salinity conditions — by 36.5–54.3 % is observed. The obtained data indicate a potentially high adaptive capacity of H. grandiflorum seedlings due to self-regulation of gas exchange processes.
