Influence of Using Some Antioxidant Oils and Natural Plant Extracts on Yield and Quality of Crimson Seedless Grapevines
Year: 2021
Type: article
Abstract: This research is a helpful step in viticulture aimed to highlight a category of some natural agents effects particularly; grape seed oil (GSO), roselle seed oil (RSO), roselle extract (RE), red chili pepper extract (CPE) and ascorbic acid (As).Thrice sprays during 2019-2020 seasons of each had applied on Crimson Seedless grapevines grown at Aga, Dakahlia Governorate, Egypt.Findings showed that, As + GSO followed by As + RSO and As + CPE sprays promoted shoot length, leaf area and wood ripening coefficient, total yield, cluster and berry weight, berry size, berries firmness and SSC %.Furthermore, As + CPE spray maintained the lowest acidity, but As + RSO spray had the highest SSC/ acid ratio.In addition, As + GSO spray raised total sugars, phenols, anthocyanin and chlorophyll contents.Also, all treatments raised N %, P % and K% values significantly more than the control.Finally, it could be summarized that 0.2 % sprays of plant-derived agents like GSO, CPE or RSO combined with 200 ppm of As; have a synergistic effect on grapes vegetative growth, yield, cluster physical and chemical quality parameters compared to the control.
