.Большинство травянистых растений хранят органические вещества в подземных побегах. Они могут быть нескольких видов: корневище, луковица и клубень. Развитие подземных побегов происходит в абсолютно другой среде, чем надземных, ведь солнечный свет не проникает в почву.
Побеги, живущие под землёй, под влиянием комплекса условий, резко отличных от наземной среды, почти полностью утратили функции фотосинтеза и приобрели другие, не менее важные жизненные функции, такие как способствование перенесению неблагоприятного периода, запасания питательных веществ, вегетативного возобновления и размножения растений.
