Abstract:
During the growth and development of the sporophytic capsules of some moss species, negative gravitropism is changed for a positive one. Horizontal clinostat rotation induced unregulated growth of the sporophytes and their twisting; some of sporophytes remained straight, however. It has been established that the change of the gravitropic reaction is related to capsule formation and to the redistribution of amyloplast cells of the sporophyte graviperception zone.
