Studies were conducted to determine the effect of potassium salt of indole-3-acetic acid on the rooting process and the quality of rooted grape cuttings. The work was completed in 2017–2018 on the sample of varieties Korinka russkaya and Victoria, which are most common in household plots of the Republic of Tatarstan. The lignified shoots of grapes were harvested in November and stored in plastic bags at a temperature of 2 ... 4°C. Before cuttings, they were soaked for 48 hours in tap water at room temperature and cut into two-kidney cuttings. The basal ends of the cuttings were furrowed. The ends of the cuttings (5 ... 6 cm) were immersed in solutions according to the experimental scheme: distilled water (control); indole-3-butyric acid, 3000 mg/l (standard); potassium salt of indole-3-acetic acid, 5000 mg/l; potassium salt of indole-3-acetic acid, 10000 mg/l. Processing the cuttings by potassium salt of indole-3-acetic acid composition at a concentration of 10,000 mg/L significantly improved the rooting process. The share of rooted cuttings in Korinka russkaya variety in 2017 was 77.5%, in 2018 - 90.0%. The greatest callus formation (29.0 ... 43.8%), the number of roots on the cuttings (26.0 ... 23.9 pcs.), The length of the roots (133.9 ... 140.1 cm) were noted in Victoria variety. A solution of indole-3-butyric acid at a concentration of 3000 mg/L also improved rooting compared to the control. Grape varieties varied significantly in the rooting of cuttings. On the Korinka Russkaya variety, all parameters on average over 2 years were higher than on Victoria cuttings.
Relevance. Applying exogenous auxins to the cuttings of grapevines is a common practice in viticulture to improve the rooting process. The potassium salt formulations of auxins have been documented to be more, less, or equally efficient as acid formulations in rooting stimulation of cuttings depending on the genetic features of the plant, type and concentration of auxin, type of cuttings, and many other factors.Methods. The present study aimed at evaluating the effect of potassium salt of indolyl-3-acetic acid (KIAA) on rooting of the hardwood cuttings of two grape cultivars namely, Korinka russkaya and Victoria, which are commonly planted by grape growers of the Tatarstan Republic. The study was conducted in 2018 and 2019 under hydroponic conditions in a controlled-environment growth chamber in Kazan State Agrarian University. The cuttings were treated with 1) KIAA at two concentrations (5,000 and 10,000) ppm; 2) β-indolyl-butyric acid (IBA) 3,000 ppm (as a check treatment) and 3) distilled water as a control.Results. Based upon the overall results, KIAA significantly improved the rooting process of both investigated cultivars. Rooting percentage, average number of roots on cuttings as well as the quality of the root system was enhanced with increasing auxin concentration up to 10,000 ppm. IBA also improved the rooting quality parameters over the controls. The two grape cultivars differed significantly in their rooting capacity: cuttings of Korinka russkaya in both years had greater values of all the studied parameters compared with those of Victoria cultivar except for the callusing percentage, which was higher in Victoria.
When growing high-quality grape seedlings, an effective organization of production is required, aimed at the intensification and development of the industry. Rooting grapes with lignified cuttings is one of the most effective and economical methods of reproduction. The article presents the results of three-year studies (2019-2021) to study the effect of biologically active substances on the rootability of lignified grape cuttings. The object of the study is the Victoria grape variety obtained by crossing Vitis amurensis and Vitis vinifera with the Save Vilar 12-304 variety in VNIIVIV im. Yakov Ivanovich Potapenko. The variety under study is a table variety with an early ripening period, characterized by increased resistance to powdery mildew, oidium and gray rot. Withstands low negative temperatures up to -26 ... - 27ºC, with a period from budding to removable ripeness of 115-120 days. During the experiment, records were made about the growth of callus, rooting and output of standard seedlings. When studying the effect of biologically active substances on lignified cuttings, they were treated with salicylic and β-indolyl butyric acids at concentrations of 2000 and 3000 mg/l. As a result of the conducted studies, it was found that the highest percentage of rooting was obtained in the variant using salicylic acid at a concentration of 2000 mg/l and reached 84.5% on average over three years. The same version of the experiment showed the maximum yield of standard seedlings - up to 76.3% on average for three years.
The study aimed to improve fruit set and plant performance to increase tomato productivity by studying the effect of plant growth regulators on tomato plants (Lycopersicon esculentum). A specific experiment has been carried out to study the effect of plant growth regulators Hemo bles (humic acid, 850g/kg) at applied doses (250, 500 and 700 ppm) and Magictone (naphthalene acetic acid and naphthalene acetamide, 5…12.5 g/kg) at applied doses (250, 500 and 700 ppm) on growth and physiological characteristics of tomato plants (Big Beef F1). The experimental design was a Complete Randomized Blocks Design. Both Hemo bles and Magictone were applied three times (spraying on plants at 30 days after planting (DAP), 60 DAP and 90 DAP). The obtained results showed that, applying Ener-850 humic acid caused the highest significant plant height (264.6 cm), number of leaves/plant (45), stem diameter (1.9 cm) and fruit weight (137 g) during the two seasons. In addition, applying Magictone resulted in the highest significant flower number (48.1), fruit number (35.1) and flower clusters number in the plant (13.6). Additionally, humic acid significantly increased dry weight (75.1 g) of arial parts with improving of tomato fruit quality via enhancing the concentrations of ascorbic acid, level of vitamin C and carotenoid content. The results were analyzed using one-way analysis of variance (ANOVA) followed by Tukey’s HSD test with α = 0.05 with the help of MINITAB (v. 19.0) program.
