Influence of plant growth regulators on forming the productivity of sunflower (Helianthus annuus L.) in the Steppe of Ukraine against the background of Euro-Lightning herbicide application

Journal Title: «Таврійський науковий вісник» - Year 2016, Vol 96, Issue

Abstract

The results of research on the influence of AKM and Emistim plant growth regulators on growth, development and yield formation of sunflower in the conditions of insufficient moistening of the southern Steppe of Ukraine against the background of Euro-Lightning herbicide application are presented. Pre-sowing treatment of sunflower seeds with plant growth regulators causes an increase in leaf surface area by 26 %; reduces the duration of phenological phases of development on average by 2 – 4 days; increases resistance of sunflower plants to abiotic stresses and increases productivity by 31.5 %. The comparative assessment of results of research is carried out and the ranged row for Armada hybrid is established. The optimal is the option of pre-sowing treatment of seeds with AKM plant growth regulator – the first rank ( ( ) 1  х =1.90).
