Histochemical Localization of Histones, DNA and Proteins in the Anthers of Mele-fertile and Male-sterile Plants

Abstract

The evaluation of histochemical localization of histones. DNA and total protein in the anthers of male-fertile as well as cytoplasmic, genic and chemically indLlced male-sterile plants of Allium cepa, Beta vulgaris, Capsiculee annuum, Cucumis leeelo, Cucur-bita maxima, Datura alba. Ranunculus muricatus, Sesamum indiculee, Solarnum melon-gena and Triticum aestivum revealed that the anthers of male-sterile plants were markedly deficient in these substances. It is concluded from these observations that this deflciency, acting as a limiting factor for pollen development in all probability, was caused by the inhibition of vascular supply in sterile anthers.
