Characterization of Energy Metabolism during Ontogenesis of Fiber Flax in Heterosis

Characterization of Energy Metabolism during Ontogenesis of Fiber Flax in Heterosis The contents of adenine nucleotides and nicotinamide coenzymes, along with morphological traits, were studied in fiber flax cultivars and F1 hybrids at various ontogenetic stages. The bioenergy parameters of heterotic hybrids proved to be significantly higher than in the parental cultivars, suggesting a higher activity of energy-producing processes determining the intensity of plant growth and development.

Abstract

The contents of adenine nucleotides and nicotinamide coenzymes, along with morphological traits, were studied in fiber flax cultivars and F1 hybrids at various ontogenetic stages. The bioenergy parameters of heterotic hybrids proved to be significantly higher than in the parental cultivars, suggesting a higher activity of energy-producing processes determining the intensity of plant growth and development. The character of the heterosis effect on morphological, bioenergy, and productivity parameters was evaluated in the F1 hybrids varying in the extent of heterosis. Hybrids that displayed positive dominance or superdominance in productivity parameters showed heterosis for most bioenergy traits.
