МРНТИ 68.35.03, 87.12.09; 87.12.15                                                             

№2 (2021 г.) Рахымжан Ж., Текебаева Ж.Б., Бейсенова Р.Р.  Проведена обработка семян Сведа солончаковая (Suaeda salsa Pall) в различных концентрациях солевых растворов (почвенный экстракт, Na2 SO4 и NaCl) - 0; 0,6; 1,2; 1,8; 2,8; 3,6 г/100 мл. Мониторинг реакции проросших семян на соль при физиологическом давлении дает теоретическую основу для ее выращивания и использования. Результаты эксперимента показали, что семена Сведа солончаковая хорошо адаптированы к засоленным почвам и при прорастании способны выдержать высокий солевой стресс. Было замечено, что влияние солевого стресса на прорастание семян было следующим NaCl> почвенный экстракт >Na2 SO4 . Вследствие увеличения концентрации соли всхожесть семян, наоборот, значительно снизилась. Было обнаружено, что семена Сведа солончаковая по-разному реагируют на разные стрессовые концентрации солей.

Ключевые слова: засоленные почвы, галофиты, всхожесть, концентрация солей, Сведа солончаковая, почвенный экстракт.
