POLLEN AND SEED SURFACE MORFOLOGY IN SOME REPRESENTATIVES OF THE GENUS RHODODENDRON SUBSECT. RHODORASTRUM (ERICACEAE) IN THE RUSSIAN FAR EAST
Abstract
Comparative study of pollen and seed morphology of three species of Rhododendron L. subsect. Rhodorastrum (Maxim.) Cullen (Rh. dauricum L., Rh. mucronolatum Turcz., Rh. sichotense Pojark.) is performed. Results of discriminant analysis of the total of morphometric characters of pollen and seeds have proved the distinctness of all three species from each other. Differences of polen are observed in the type of sculpture (granulate, rugulate, microrugulate) and in the diameter of tetrads. The coefficient of elongation of the exotesta cells is established as a valuable morphometric characterDownloads
