Полиплоидия - наследственное изменение, при котором многократно увеличивается гаплоидный набор хромосом. Полиплоидные растения отличаются от обычных тем, что они имеют крупные размер, устойчивы к неблагоприятным условиям окружающей среды, имеют повышенное содержание ценных веществ.  И еще у полиплодиных растений нарушены пропорции отдельных органов.
