Title: SEEDLING GROWTH-PROMOTING COMPOSITION, A KIT, A METHOD FOR APPLYING THE FORMER, AND USE OF THE VOLATILE ORGANIC COMPOUNDS COMPRISING THE COMPOSITION
Abstract:
The present invention relates to plant growth-promoting compounds and, in particular, the use of volatile organic compounds, such as 2-nonanone, 2-undecanone, 2-tridecanone and 2-pentadecanone, hereinafter referred to as 2K-4, which exhibit growth-inducing activity. Said compounds are applied to crops prior to transplanting them into the field as they strengthen roots by inducing root growth (length of primary root, length of secondary roots, length and density of root hairs) and leaf growth (leaf weight), thereby decreasing stress in the crops due to the change of environment, in other words decreasing the probability of dependency of growth on soil type and change of environment.
