Семена озимой пшеницы сортов Краснодарская 99, Эпоха одесская в условиях высокого осмотического давления сохраняют существенную способность к прорастанию. Интенсивность корнеобразования, роста зародышевых корней и стеблей в длину у проростков снижается у всех сортов с повышением концентрации сахарозы. Сорт Наталка в меньшей степени подвержен отрицательному воздействию осмоса, что проявляется в сохранении высокой всхожести семян, снижении угнетения, роста корней и стеблей проростков.
