Histochemical localization of enzymes in the stigma and style of Gossypium hirsutum L. during pre- and post-pollination stages.
The distributional pattern of some enzymes (esterase, beta-D-galactosidase, succinate dehydrogenase and malate dehydrogenase) is described in the dry stigma and closed style of Gossypium Hirsutum L. during pre- and post-pollination stages. All the four enzymes indicated granular reaction and increased activity in the transmitting tissue and its surrounding cells during post pollinated stage. The possible physiological role of these enzymes in pollen tube growth in vivo in stigma and style is discussed.
