Leaf and sepal colleters in Calolisianthus speciosus Gilg (Gentianaceae): a morphoanatomical comparative analysis and mechanisms of exudation

Microclones of in vitro vegetable sweet potato (Ipomoea batatas L.) were received and the formation of colors on their leaves was studied. The studies were carried out on three varieties of sweet potato that differ in the color of their pulp and the peel of the tubers as well as in different ripening periods: Purple, Jewel, and Muskatny. The effect of ½ norm of mineral salts MS medium, 1 norm MS and 1½ norm MS on the morphometric parameters of sweet potato microclones was studied. It was established that the use of ½ norm of mineral salts according to MS medium led to the production of rapidly growing axillary and adventitious shoots and the formation of a powerful root system in the basal part of microcuttings. The formation of secretory outgrowths was found for the first time on the leaves of sweet potato microclones when cultured under in vitro conditions. Neoplasms were referred to colleters and their characteristics were given. The dependence of the colleter formation on the microclone leaves on the cycles of culture is shown.
