This work presents the data on five tomato genotypes and describes a procedure that includes presowing seed treatment, sowing and extraradicular treatment of seedling transplants with an aqueous solution of the steroid glycoside 3-O-{[β-D-glucopyranosil (1→4)]-[β-D-glucopyranosil (1→3)]-β-D-galactopyranoside}-(25R)-5α-furostan-3β,22α,26-triol-[26-O-β-D-glucopyranoside], isolated from Hyosciamus niger L., at concentrations of 0.001%, 0.005%, and 0.01% at the 3-4 leaf stage followed by treatment of inflorescences of the first, second, and third raceme with the same concentrations. The product of plant origin has demonstrated a stimulating action on seed germination rate and root length. The employment of the steroid glycoside under study has allowed an increase of the flower and fruit number on the first three clusters and, hence fruit productivity and quality. The concentration of 0.005% has proved to be the most efficient for all the samples studied. The experimental findings have confirmed that the steroid product of natural origin Hyosciamoside F has a positive effect on both reproductive processes and fruit productivity and quality resulting in acceleration of tomato growth and development and increase of total (up to 20.7%) and market (up to 35.7%) productivity. |
