Blue light response of stomata with starch-containing (Vicia faba) and starch-deficient (Allium cepa) guard cells under background illumination with red light

摘要: Abstract Two plant species, Vicia faba with starch-containing guard cells and Allium cepa starch-deficient cells, were compared for stomatal response to blue light in order clarify whether hydrolysis of starch is involved opening stomata by light. The rates transpiration leaves increased upon illumination strong red very weak remarkably enhanced the these species when applied simultaneously same without background was much less effective stomata. No significant difference found between two induced It concluded that effect not brought about via observable only photosynthetic mechanism operating
