The influence of exogenous plant growth regulators there upon the black currant (Ribes nigrum l.) productivity and its berry quality

As a result of investigations on growth and development processes in vegetative and generative organs for black currant plants the effectiveness of exogenous plant growth bioregulators Bioglobin, Epin^TM and Emistim S was determined concerning its influence upon the productivity and berry quality the black currant variety Leleka, which is growing in the first time with using such technology.

The use of exogenous plant growth regulators Epin^ТМ, Emistim S and Bioglobin on black currant plantings had significantly stimulated the growth processes and formation of berry yield.

Among studied preparations the most effective was Epin^ТМ – a synthetic analogue of phytohormone 24-epibrassynolid.

The specific reaction on the action of bioregulators was detected. Epin^TM essentially increased the quantity of bunches per 1 bush, in consequence of yield was increased on 54%, as to Emistim S this result was some less (on 48%). Bioglobin had smaller influence on formation of bunches and therefore a productivity not exceed 24% to control.

Our results give the reason to recommended Epin^TM and Emistim S for using in technologies of growing black currant.
