(SOLАNUM TUBEROSUM L.)
MORPHOGENESIS IN COURSE OF
MICROPROPAGATION IN VITRO

Description
The article gives the results of the study of an effect of
mechanochemical powder of wood green of Abies
(MPA) on potato morphogenesis in vitro. The study
involved the hormone-free nutrient mediums (MS, ½
B5, ½ LS) for growing microcuttings from preliminary
obtained aseptic plants. Plant morphogenesis was
observed on the 15th and 30th days. At that, the number
of developed shoots, plant height, leaves number,
rhizogenesis rates, root number and length were
estimated. MPA appeared to have the regulatory effect
on morphogenesis of potato microcuttings. Based on mineral composition of the nutrient agar medium for
potato microcuttings growing, MPA at 100 mg/l
concentration induced root development (½ B5
medium), reduced height of shoots (MS medium),
while the number of leaf blades was not affected
