| Abstract | ||
| A pot experiment was conducted during 2014 and 2015 seasons to test the efficacy of eleven plant extracts (seven oils of garlic, onion, peppermint, olive, clove, flax seed and anise plus four extracts of turmeric, green tea, moringa leaf and red chillies) each at 5% on growth and nutritional status of Flame seedless grapevine transplants. Results showed that the previous eleven plant extracts were very effective in enhancing all growth aspects (plant height, stem thickness, number of leaves/plant, number of lateral shoots/plant, main shoot length, number of leaves/shoot, leaf area and dry weight of whole plant), root parameters (root distribution area, number of secondary roots per main root, main root length and dry weight of roots/plant), leaf pigments (chlorophylls a &b, total chlorophylls and total carotenoids), percentages of total carbohydrates and soluble sugars in the leaves and uptake of N, P and K by transplant over the check treatment. The best plant extracts in this respect could be arranged as follows in descending order garlic oil, turmeric extract, onion oil, green tea extract, moringa leaf extract, red chillies extract, peppermint oil, clove oil, olive oil, flax seed oil and anise oil. Conclusively, for producing vigorous flame seedless grapevine transplants, it is necessary to spray the one-year old transplant with garlic oil or turmeric extract each at 5% four times at the middle of April, May, June and July yearly. | ||
