Response of Flame Seedless Grapevines to Foliar Application of some Micronutrients and Glutathione
Posted on Thursday January 01, 1970
This study was carried out during 2020 and 2021 seasons to examine the effect of spraying glutathione at 0.025 to 0.1% and/ or citrine compound (2% Zn + 2% Fe + 2% Mn) at 0.05 to 0.2 % were sprayed three times from growth start (first week of March), just after berry setting (first week of Apr.) and three weeks later (last week of Apr.). on growth aspects, vine nutritional status, yield , berries colouration % as well as physical and chemical characteristics of Flame seedless grapes, Subjecting the vines to glutathione at 0.025 to 0.1% and or citrine compound at 0.05 to 0.2% was very effective in enhancing main shoot length, number of leaves/ shoot, leaf area, wood ripening coefficient, cane thickness, pruning wood weight, as well as leaf photosynthesis pigments, N, p, K , Fe, Zn and Mn in the leaves , yield, cluster weight and dimensions, berries colouration % and both physical and chemical characteristics compared to the control treatment. Using citrine compound was favourable than using glutathione in this respect Combined application of glutathione and citrine compound obviously surpassed the application of each alone in this respect, The best results with regard to yield berries colouration % and quality of the berries were recorded on the vines that received three sprays (at growth start, just after berry setting and three weeks later) of glutathione at 0.05% and citrine compound (2% Zn + 2% Fe + 2% Mn) at 0.1%.
Effect of Iron Nano-particle as Foliar Spray on Growth, Seed Yield and Active Constituents of Silybum marianum L. Plants
Posted on Thursday January 01, 1970
At the Experimental Farm of Ismailia Agriculture Research Station, Ismailia Governorate, Egypt, the experimental work was carried out over the course of two successive growing seasons in 2018–2019 and 2019–2020 in order to investigate the effects of iron oxide nanoparticles (7.5, 15.0, and 30.0 ppm) in comparison to unsprayed (control plants) on seed yield, growth and active Silybum marianum L. constituents. Three repetitions of a randomized complete blocks design were used for the experiment. Spraying Silybum marianum L. plants with Fe3O4-NPs at 30 ppm increased plant height, number of leaves/plant, number of inflorescences/plant, root length, stem diameter, dry weight of roots, number of roots/plant, inflorescences/plant and herb, chlorophyll a, chlorophyll b and total chlorophyll (a+b), N, P and K contents in leaves, seed yield /feddan and Fe concentrations in fruits, TXF, SBN, SCN, SDN, ISBN and total silymarin in fruits, in both seasons.
Effect of Zinc Nano-particle as Foliar Spray on Growth, Seed Yield and Active Constituents of Silybum marianum L. Plants

The experimental work was conducted during the two successive seasons of 2018/2019 and 2019/2020 at the Experimental Farm of Ismailia Agriculture Research Station, Ismailia Governorate Egypt, to study the effect of zinc nanoparticles as foliar spray (0.25, 0.50 and 1.0 g/l, beside unsprayed (control treatment)) on growth, seed yield and active constituents of Silybum marianum L. The experiment was designed as randomized complete blocks design with three replicates. As for the response of Silybum marianum L. plants to foliar application with zinc nanoparticles, results indicated that, treating Silybum marianum L. with ZnO-NPs at 1 g/l as foliar spray increased plant height, number of leaves/plant, number of inflorescences/plant, stem diameter, root length, number of roots/plant, dry weight of roots, herb and inflorescences/plant, chlorophyll a, chlorophyll b and total chlorophyll (a+b), seed yield /feddan., N, P and K contents in leaves and Zn concentrations in fruits, TXF, SDN, SBN, SCN, ISBN and total silymarin in fruits, in both seasons.
