Sowing properties of sunflower seeds of Talento hybrid under the influence of a modified plant growth regulator
Abstract
The improvement of agricultural crop cultivation technologies enables the production of high sunflower yields with high-quality indicators. One such element is pre-sowing seed treatment. This study aimed to investigate the effect of a plant growth regulator supplemented with calcium on the sowing properties of sunflower seeds. The experiment was conducted under laboratory conditions. For pre-sowing seed treatment, a semi-synthetic film-forming agent with an anti-stress effect was used, which was modified with Ca2+ ions in the form of calcium chloride. It was established that the encrustation of sunflower seed with a growth regulator stimulates germination processes and activates the initial stages of sunflower organogenesis. This increases the indicators of germinative vigour and germination capacity. Adding calcium to the plant growth regulator contributes to a further increase in the indicators of germinative vigour and seed germination capacity of sunflowers by 5.4% and 7.7%, respectively, compared to the control. At the same time, the hypocotyl length increased by 1.51 times compared to the control, while the root length increased by 1.37 times. The accumulation of organic substances in sunflower seedlings is characterised by an increase in dry matter. When calcium was added to the plant growth regulator, a more intensive accumulation of dry matter in the hypocotyl and root was observed compared to the control and the variant using only the growth regulator. The establishment of a ranking range indicated that, based on the parameters studied, the optimal treatment option for the pre-sowing treatment of sunflower seeds is the application of a plant growth regulator containing calcium ions at a concentration of 1.0 g/L. The use of this preparation is relevant and promising for studying the formation of sunflower plant productivity with increased quality indicators under field conditions
