The article presents results of the assessment of the
efficiency of non-hormonal preparations which were
not earlier applied in culture in vitro with high physiological
activity (the preparations received by production
of furfural, and also derivatives and compositions
of organic acids) during regenerations of microshoots
of plum, comparison of their influence with
influence of growth regulators which are traditionally
used in clonal micropropagation. These experimental
preparations were received when processing waste of
agricultural production. In this work we used: technology
of clonal micropropagation of plants of in
vitro, statistical data processing by method of the
dispersive analysis. The objects of researches were
microshoots of plum of a Stanley variety. We have
established that on mediums with the preparations
"Universal", sodium succinate, potassium succinate,
amber acid, L-1 the large, intensively colored plum
microshoots develop surpassing control (medium
with BAP of 1 mg/l, IBA of 0,1 mg/l, gibberellic acid
of 0,5 mg/l) in morphometric parameters. Thus, the
preparations "Universal", sodium succinate, potassium
succinate, amber acid, L-1 in concentration of 4,0
mg/l proved as the growth factors which are favorably
influencing on plantlets’ regeneration and a qualitative
condition of microshoots of plum
Clonal micro-multiplication – is this the basic method
of obtaining the qualitative virus-free planting
material. The high quality specificity of the explants
reaction of the grapes varieties to the composition of
nutrient medium requires the individual selection of
the medium components for the most successful multiplication
in vitro. In the article we present the results
of studies on the cultivation of the grapes apexes
in vitro the modified medium with the reduced
content of macrocells. As a result of conducted investigations
we have established that for the grapes varieties
of Academic Trubilin, Artemis, Gurman
Kraynova, Maria Kallas, Nizina, Petit Verdo and
Traminer Black the most effective introduction into
the in vitro culture (acclimatization of apexes 80-
100%) occurs on modified nutrient medium to
Murasige and Skoog (1962), by being differed in
terms of the content macro-elements (mG/l):
NH4NO3 – 1237; KNO3 – 1425; MgSO4 ·
7N2O – 277,5; KN2PO4 · H2O – 277,5, of the
vitamin Of v1 – 10,0 mG/l, nicotinic acid – 4 mG/l.
Remaining varieties of Kishmish luchistiy, Preobrajenie,
Roshfor K and Yubiley Novocherkasska in the
same medium were developed slowly and in a different

The analysis of fruit crops saplings production in the Krasnodar region is presented. The problems of the modern fruit crops saplings production in the region are allocated and possible ways of decision these problems are given
