This Concept Map, created with IHMC CmapTools, has information related to: Regulation of flowering in flowering plants (Class Concept Map), phytochrome exist in 2 forms Pfr, (1) Plants respond to exposure of relative day length, high level functions to stimulates flowering, stimulates flowering in Long day plants (LDP), Short day plants (SDP) flowers when Pfr concentration is low, (2) leaves secrete florigen (flowering hormone), Long day plants (LDP) flowers when Pfr concentration is high, flower buds & axillary shoots causes flowering in Short day plants (SDP), Pr absorbs red light (660nm) DAY, physiological response to the environmental by photoreceptors, Long day plants (LDP) flowers when day is longer than critical (night) maximum, (1) Plants are grouped into Long day plants (LDP), phytochrome exist in 2 forms Pr, inhibits flowering in Short day plants (SDP), high level functions to inhibits flowering, Pfr absorbs far-red light (730nm), Pr is inactive form, Pfr degrades gradually during night to Pr, flower buds & axillary shoots causes flowering in Long day plants (LDP), Short day plants (SDP) are Chrysanthemum, tobacco, strawberry, soya bean, rice
