Abstract
The article presents the results of studies for 2019. The aim of the study was to identify the effectiveness of growth regulators Prorotok and HB-101 in stimulating growth processes in seeds and seedlings of eggplant culture grown in the Khabarovsk Territory. The objectives of the study were to study the growth-stimulating effect of the studied drugs based on the analysis of data on the energy of germination and germination of seeds, as well as morphological parameters of seedlings of the eggplant culture grown in the territory of the village. Dzhonka of the Nanay district of the Khabarovsk Territory. The research was carried out on two varieties of eggplant Boyarin F1 and Mishutka. The experiment was carried out in three replicates in accordance with the agricultural technology generally accepted for the territory of the Khabarovsk Territory. As a result of the studies carried out, inhibition of growth processes was revealed in the variants of the experiment with pre-sowing seed treatment with Prorostk and HB-101 in the form of soaking them for two hours in working solutions of preparations with a concentration of 0.25, 0.5, 1% compared to the control a variant in which the seeds were soaked in water. Analysis of the morphological parameters of eggplant seedlings revealed the following. In the variants of the experiment with the concentration of the Prorostka working solution of 0.25%, the plants of varieties Mishutka and Boyarin F1 showed an increase in the length of the leaf blade by 8 and 13%, the length of the stem by 7 and 17%, respectively, compared with the control. In the variants of the experiment, in which the plants were treated with the Germination solution with a concentration of 0.5%, a significant increase in the length of the leaf blade by 6 and 11%, and the length of the stem by 8 and 15%, respectively, was revealed. The analysis of the efficiency of HB-101 showed a growth-stimulating effect at the stage from seed germination to the formation of the first two true leaves in plants of the Mishutka variety in the variant with a working solution concentration of 0.25%. The increase in the length of the leaf in this case was up to 35%, the length of the stem up to 20% in comparison with the control variant. In the period from two true leaves to planting seedlings in open ground, a high rate of growth processes was noted in variants with working solutions HB-101 0.25 and 0.5%. The use of the HB-101 preparation at the stage of presowing treatment, as well as during the cultivation of seedlings of plants of the Boyarin F1 variety, is not advisable, since a decrease in the rate of growth processes was revealed in the plantings of this variety in comparison with the control option.
