Response of aboveground vegetative organs of Solonum tuberosum L. to short chain fatty acid (nonanoic acid) applied in different technical parameters of measurements

摘要

Nonanoic acid, also called peralgonic acid is a short chain fatty acid that occurs naturally and is safe for humans and animals. Nonanoic acid characterized by quick action and high efficiency. The effects of nonanoic acid are already seen 24 h after application. Dessiccant with active ingredient - nonanoic acid (pelargonie acid) has been analyzed in Poland in three vegetation seasons: 2012, 2013, and 2014 in cultivation of potato plant, Vineta variety. The experiments were carried out at the Field Experimental Station in Winna Góra. The aim of experimets was to define potato plant reaction on nonanoic acid applied using different sprayers, pressure and liquid flow rate. Results confirm different activity of studied compound on aboveground vegetativeorgans of potato in dependence of nonanoic acid dose applied and technical parameters of treatment - sprayers type, liquid flow rate and working pressure. Experiments clearly showed, that in dependence of evaluation of vegetation organ (leaf, stalk) thereaction on studied compound and technical parameters during its application was different.
