Regulation of rhizogenetic process at clonal micropropagation of horticultural crops
The article considers the results of scientific research on the study of biochemical and biophysical factors of the effect on the efficiency of rhizogenesis of microcuttings in horticultural crops in vitro. The effects of β-indole butyric acid (IBA), β-indole acetic acid (IAA), or α-naphthalene acetic acid (NAA) on root induction were tested in MS and QL culture media at concentrations of 0.125-1.0 mg L‑1. As a result, more efficient concentrations of hormones, which provide high intensive rhizogenesis was stated. In several forms, positive effect was obtained due to the change in source of carbohydrate nutrition and its concentration. The article presents the results of the effect of laser irradiation on rooting process in lilac microcuttings. The selection of optimal modes and methods of ultrasound irradiation allowed in 1.5-2 times increase the efficiency of rhizogenesis in microcuttings.
