FACTORS IN INCREASING YIELD AND IMPROVING QUALITY OF ANNUAL CUTTINGS OF GROUND CHERRY

Results are given from investigations into the effect of planting dates (early, medium, or late planting) and pre-planting treatment of herbaceous cuttings with root formation stimulants IMK and Kornerost on the gross output and quality of annual nurslings of ground cherry (Cerasus fruticosa) varieties Altaiskaya Lastochka, Seliverstovskaya, Shadrinskaya, and elite forms CBC 89-95-48 and CBC 89-95-53. The investigations were carried out at the Lisavenko Research Institute of Horticulture for Siberia in 2012-2013 in a three-factor experiment. It was found that the change in the gross output of annual nurslings of ground cherry was determined by such factors as variety specimen, planting date, and root formation stimulant, contributions of which were 81.8, 7.1 and 6.7%, respectively. Quality of nurslings, expressed in terms of the height of the above-ground part and the average length of roots of the first order, was measured by pair interaction of variety specimen and planting date factors as well as by variety specimen factor, root formation stimulant factor, and interaction of all factors, contributions of which were 46.4-61.6; 3.9-7.0; 17.7-27.5, and 6.5-12.9%, respectively.
