摘要

研究了杀菌剂处理对在奥特尼亚地区气候条件下栽培的葡萄植株生理过程的影响。2021年7月18日，对经0.2% Dithane M-45处理的植株进行了生理分析，分四期，每隔12天进行一次，对被Uncinula necator (Schv.)侵染的植株进行了生理分析。毛刺。其中没有进行过治疗。研究发现，与施用杀菌剂处理的葡萄植株相比，受Uncinula necator (Schv.)侵染的葡萄植株的生理过程强度较低，原因是叶片被真菌菌丝体覆盖，同化面减少，组织出现白斑和褐变。

THE EFFECTS OF THE TREATMENT WITH FUNGICIDES ON THE PHYSIOLOGICAL PROCESSES IN VITIS VINIFERA L. ATTACKED BY UNCINULA NECATOR (SCHW.) BURR. PATHOGEN

The effects of treatment with fungicides on the physiological processes were observed in Vitis vinifera L. plants cultivated in the climatic conditions in Oltenia region.The physiological analyzes were performed on July 18th 2021, both for plants treated with Dithane M-45 (0,2%), in four phases, at 12 days interval and also for the plants attacked by Uncinula necator (Schv.) Burr. in which treatments have not been performed. In the Vitis vinifera L. plants attacked by Uncinula necator (Schv.) it was observed that the physiological processes intensity is lower as a result of the reduction of the assimilation surface due to the covering of the leaves with the mycelium of the fungus, the appearance of whitish spots and the browning of the tissues, in comparison with the plants in which fungicide treatments have been performed.
