Future possibilities for maximum intensive horticultural production

Abstract

Plant growth in protected environments may be increased by improving light transmission or by providing supplementary artificial light, or perhaps eventually by improving the efficiency of the photosynthetic process. Much has yet to be learned, both of the inter-relations between crop growth and various environment factors, and of mechanisms and metabolic processes within the plant, but there is no doubt that plants have a physiological potential to yield more than they now do.
