Подготовка семян цветов к посеву
При проращивании семян необходимо знать «технологические» секреты. Для получения крепких и дружных всходов проводят предпосевную обработку семян с помощью изменения температурного режима. Семена теплолюбивых видов подогревают до +35-40°С, холодостойкие, наоборот, после замачивания охлаждают при +3-4° С. Для ускорения прорастания семян с твердой оболочкой, как у арктотиса, венидиума, душистого горошка, настурции, их на 12-18 часов замачивают в горячей воде (+40-50°С). При этом она н e должна полностью покрывать семена, чтобы те не задохнулись.
