Annotation:
Alfalfa has been cultivated for more than 3 000 years. Today, over 80 countries cultivate alfalfa on more than 30 million hectares. It is a good fodder plant with a rich ratio of protein and essential amino acids, carbohydrates, mineral salts, and other substances. Salt stress has various effects on plant physiology. For example, due to a decrease in osmotic potential, it becomes difficult for plants to absorb water, metabolism is lost, and the intensity of the photosynthesis process decreases. In this study, the salt tolerance of the Turkish alfalfa variety Gozlu-1 and the Mongolian alfalfa variety Burgaltai was compared using NaCl in vitro and ex vitro.
According to the results of the study, the Gozlu-1 variety’s germination stress tolerance index is 11.2–39.0 % higher than the Burgaltai variety. When comparing artificial salt tolerance with some morphological parameters, the Gozlu-1 variety showed 1.2–18.4 % lower chlorophyll content than the Burgaltai variety, while the water absorption intensity of the Gozlu-1 variety was 27.1–39.8 % higher than the Burgaltai variety.
