Development of patterns of candlegrass seed quality formation (Panicum virgatum L. millet) depending on its biological features and influence of biotic and abiotic factors. and research possible ways to reduce its biological dormancy in order to increase seed germination.
popup.description2
The aim of the study was to determine the specific features of growth and development of seed-bearing plants and the formation of yield and seed quality of switchgrass depending on biological characteristics and technological elements — namely, the timing of seed harvesting, the year of crop vegetation, maturity groups of accessions and varieties, and methods of pre-sowing seed preparation.
The latter included cleaning the seed mass from coarse and fine impurities, scarification, stratification, sorting by aerodynamic properties and specific weight, which improves its physical and mechanical characteristics (increasing seed weight) and biological properties (enhancing seed germination).
A comprehensive method for separate seed harvesting at 75–100% panicle browning combined with pre-sowing preparation was developed, ensuring high seed yield — 118–136 kg/ha with germination rates of 40–54%.
