| description | Purpose. To define morphological peculiarities of the different types of shoots of switch grass (Panicum virgatum L.) in the context of introduction in the Right-Bank Forest-Steppe and Polissia zones of Ukraine.
Methods. Morpho-physiological and ontogenetic analysis, morphometric technique, statistical evaluation.
Results. It was found that P. virgatum plants were producing the following types of shoots: vegetative-generative short or long rhizomatous ones (they appeared as in the underground part of a maternal shoot in «the area of shortened internodes» and in the base of its aboveground part); vegetative underground and aboveground ones (they are forming both in the axils of scales of the underground part of a maternal shoot and in the axils of cauline leaves); generative aboveground shoots (borne in the axil of cauline leaves). Morphological parameters and features of morphogenesis of reproduction, resting and secondary buds have been described.
Conclusions. During flowering phase of maternal shoot, P. virgatum reproduction buds were on the organogenesis phase I–II, their bursting occured after maternal shoot has flowered. The correlation of internodes length, leave blades and sheaths has been established. The maximum values of the above parameters were observed in the middle part of the prefloral zone of the stem. In the context of introduction, panicle earing came in the third decade of July, flowering began in the first decade of August. It was revealed that complete flowers are bloomed faster than the staminate ones. |
