RESULTS OF STUDYING THE WAYS TO STIMULATE ROOTING ABILITY IN SUBTROPICAL CROPS CUTTINGS
The paper presents 3-year study results of ways to improve subtropical crops rooting. It establishes species and varietal differences in the ability to rhizogenesis, as well as optimal substrate compositions and growth regulator application that allows you to stimulate rooting, and to improve the quality of rooted cuttings of Citrus reticulata, Fortunella margarita, Feijoa sellowiana. The lower rooting ability cultivars or species have, the higher the effect from the growth regulator is. Applying peat moss and mint as additives to the background substrate peat + perlite promotes rooting of green cuttings and a more developed root system. A higher effect was obtained with the use of mint.
