Increase in willow vegetative weight depends on varietal characteristics and the period of planting material collection

The article presents the results of research on growth ground mass willow depending varietal characteristics, time harvesting planting material and use MaxiMarin absorbent gel. Methods. Field, measuring, mathematical statistical. results. was conducted with two types willow, Panfilska variety Zb-ruch rodshaped variety, at experimental field Institute Bioenergy Crops Sugar Beet during 2019–2022. It found that gel for shoots harvested both in autumn spring did not ensure increasing their survivability. Survival significantly higher than those spring, regardless characteristics. No significant increase biometric parameters – plant height, shoot thickness, number stems found, fall Zbruch ensured a reliable stems, compared to control without gel, varieties. In first year vegetation, an average three years, there tendency height thickness Zbruch, three-stemmed last recording dates, contrary, greater period shoots. intensity vegetative depends what yield cuttings or its diameter number. plants dynamics depended Growth more intense rod-shaped threestamen Panfilska. shoots, which were survival rate. Key words: cuttings, plants, stems.
