Experimental investigation of the origin of fynbos plant community structure after fire.

abstract：BACKGROUND AND AIMS:Cotton (Gossypium hirsutum) has indeterminate growth. The growth regulator mepiquat chloride (MC) is used worldwide to restrict vegetative growth and promote boll formation and yield. The effects of MC are modulated by complex interactions with growing conditions (nutrients, weather) and plant popul...
