Mode of action of gibberellic Acid and light on lettuce seed germination.

abstract：:Symptoms typical of senescence occurred in green detached primary barley (Hordeum vulgare L.) leaves placed in darkness and in light. Chlorophyll, total soluble protein, ribulose 1,5-diphosphate carboxylase protein and activity each progressively decreased in darkness and to a lesser extent in light. In all treatments...
