INFLUENCE OF CARNAVINE APPLICATION ON ROOT INITIATION AND BUD DEVELOPMENT IN RHIZOMES OF GINGER (ZINGIBER OFFICINALE ROSC)

The aim of this study was to determine the effect of carnivin treatment on the rooting and sprouting processes of Zingiber officinale Rosc. rhizomes and to identify optimal concentrations. The experiment was conducted under laboratory conditions using a completely randomized design, where rhizomes were soaked in different concentrations of carnivin solutions and observed in an aqueous environment for 45 days. Morphophysiological parameters, including sprouting percentage, root length and number, sprouting time, and biomass, were evaluated. The results demonstrated a significant positive effect of carnivin on plant development. The highest efficiency was observed at concentrations of 1.0–1.5 g/L, where sprouting reached 92%, root systems developed intensively, and maximum biomass accumulation was recorded. Higher concentrations (2.0 g/L) resulted in phytotoxic effects. The findings confirm that carnivin is an effective biostimulator for enhancing vegetative propagation of ginger.
