MORPHO-PHYSIOLOGICAL CHARACTERISTICS OF POLLEN OF PLANTS DARMERA PELTATA (Torr. ex Benth.) VOSS IN CONDITIONS OF KIEV

The article contains results of the study of morphophysiological properties of pollen the introduced plants of Darmera peltata (Torr. Ex Benth.) Voss in Kiev in connection with the prospects of their practical use in landscaping and expanding the introduction of the range. Research biometric characteristics of pollen grains (shape, size, pollen tube length) held by Nikon Eclipse E200 microscope.The potential fertility of pollen grains of plants D. peltata was determined by acetocarmine method, vitality of pollen grains was determined by wet chamber method in an incubator. Has been defined the optimal environment for the germination of pollen grains by use of sucrose solutions of different concentrations. The features of the germination of pollen tubes were analyzed.
