Variability of flower species Aquilegia L. in the Ukraine steppe
Abstract
The species of Aquilegia allocated, giving the greatest cleavage on flower color, height of generative stem, productivity bloom, flower quantitative parameters, petals. The most variable features of seedlings are number of flowers in the generative stem, color of petals and sepals, color group of flower, stable features - length and width petal, length sepal of the flower. Pollen viability and length pollen tube are variable, the polar axis, the equatorial diameter, length aperture of pollen grain - stable. Analysis of polygonal graphs showed that North American mountain forest species A. canadensis and A. skinneri are different from the other species spur length, Pyrenees A. pyrenaica - stamen exsertion, Balkan mountain forest species A. nigricans - lack of spur. A. nevadensis, A. buergeriana, A. sibirica, A. pyrenaica has the larger calyx diameter in comparison with the seedlings of other species. A. canadensis is characterized by small calyx and corolla diameter, A. nigricans, A. atrata, A. skinneri, A. canadensis - by small petal length. It was established that A. pyrenaica DC. and A. canadensis L. were characterized by the dependent of inheritance of quantitative traits of flower. The A. nevadensis Boiss & Reuter, A. buergeriana Siebold & Zucc. and A. skinneri Hook. obtained for use in selection in Ukraine steppe. It was revealed that qualitative and quantitative characteristics of the flower of plants of A. canadensis were not cleavage in F1. Pollen grains of A. canadensis has large with thickened walls, indicating the absence of cross-breeding with other species in the conditions of introduction. North American mountain forest species A. canadensis and A. skinneri are large aperture of the pollen grains in comparison with the Euro-Asian species. Identified species of Aquilegia of pollen which germinates on the artificial environment: A. buergeriana , A. sibirica Lam., A. canadensis , A. alpina L., A. aurea Janka, A. flabellata Siebold & Zucc.
