Abstract:

The research was carried out in 2017–2019 in the conditions of the Right-Bank Forest Steppe of Ukraine. The results of study, the effect of spraying by certain amino acids; salicylic (300 ppm), gibberellin (150 ppm) and ascorbic acids (200 ppm) on garlic (Allium sativum L.) plants are presented in the article. It was found that amino acid solutions improves the antioxidant state: the activities of SOD, CAT, POD, GR, GST in treated leaves tended to increase, the activity of SOD was higher than the control of 7.5–15.0%; CAT (27.4–45.9%); POD (7.0–83.0%); GR (5.4–49.9%); and GST (14.8–41.3%). It was noted that the content of chlorophyll a+b in the leaves significantly increased (2.6–10.8%), The use of amino acids increased the accumulation of dry matter by 1.4–4.0%. The yield increase was 1.14–2.27 t ha-1 (7.7–15.3% compared to control). The content of B vitamins in the garlic cloves was greatly influenced by gibberellic acid, where increasing the amount of B vitamins reached to 21.9% relative to control The use of salicylic and ascorbic acids increased the amount of B vitamins by 7.6 and 8.2%, respectively. The most significant increasing of C vitamin content was observed by spraying of plants with ascorbic acid (+12.5%), whereas by spraying with salicylic and gibberellic acids its content increased by 6.0 and 7.5%, respectively. In the future, the data obtained can be used to reduce the impact of abiotic factors on the physiological state and productivity of garlic plants. Also, the obtained data will serve as a theoretical basis for producers in view of the purposes for which the products are grown (for sale in fresh form, processing or storage).

Abstract:

The purpose of investigation is to study the biological and morphological features, to establish the economic and valuable characteristics of the introduced and local forms of Allium ampeloprasum L. in comparison with Allium sativum L. and to study the effect of removal of the scape in the yield. The studies used field, statistical, settlement and analytical methods. The weight of the bulb without removing the inflorescence shoot of the cultivar Sofiivskyi was 28.4–53.3 g smaller than the variety samples No. 2 and No. 3 respectively. With removing the scape the difference increased by 60.5–68.6 g. The yield of No. 2 variety sample Allium ampeloprasum L. without removing the scape was lower than the standard by 1.7 t ha-1 while the variety sample No. 3 exceeded the standard by 1.1 t ha-1. With the removal of inflorescence shoot the yields of variety samples No. 2 and No. 3 exceeded the cultivar Sofiivskyi by 1.6 and 2.2 t ha-1. It has been established according to the researches that introduced forms of Allium ampeloprasum L. have high indicators of economic and valuable characteristics, but they are limited in the first years of cultivation, by the period of adaptation to the new soil and climatic conditions.
