| Abstract | ||
| This research was conducted on ten-year-old ‘Flame Seedless’ grapevines (Vitis vinifera L.) grafted on ‘Freedom’ grape rootstocks in clay soil under a flood irrigation system at a private grape orchard, El-Baramon Experimental Farm, located at the Horticulture Research Institute, Egypt. 31°11′98′′ N, 31°45′13′ E, for two seasons, 2023 and 2024. Dormex at a rate of 3% and some plant extracts at a rate of 10% (garlic, onion, licorice, and seaweed extracts) were foliar spray treatments in the fourth week of January. The results showed that spraying dormex at a rate of 3% had the earliest date of bud burst stage, date of vegetative growth stage, date of flowering stage, and harvest stage and increased bud burst percentage, bud fertility percentage, and number of clusters, followed by onion and garlic extract at a rate of 10%, followed by licorice extract at a rate of 10%, and followed by seaweed extracts at a rate of 10%. Dormex at a rate of 3% and some plant extracts at a rate of 10 % improved vegetative growth, yield per vine, cluster weight, cluster length, and hundred-berry weight. Application of seaweed extracts at a rate of 10 % gave the highest vegetative growth parameters. | ||
