Inhibition of photosynthesis of sunflower leaves by an endogenous solute and interdependence of different photosynthetic reactions.

abstract：:Six authentic gibberellins marginally promoted hypocotyl lengthening of etiolated lupin seedlings whereas extracted lupin "gibberellin-like" compounds were ineffective. However, dwarfing by AMO-1618 [2'-isopropyl-4'-(trimethyl-ammonium chloride)-5'-methylphenyl piperidine carboxylate] was totally counteracted by co-ap...
