Station, Ismailia Governorate, Egypt. This study was carried out to investigate the effect of foliar spraying with some growth regulators (gibberellic acid (GA3) at 100 and 200 ppm, kinetin (Kin) at 100 and 200 ppm beside the control treatment) and a microelements mixture at (0, 1, 2 and 3 g/l) on vegetative growth, root system and quality of peace lily(Spathiphyllum wallisii Regel) plant. Results showed that the interaction treatment between spraying peace lily plants with Kin at 100 ppm in addition to the microelements mixture at 2 g/l gave the highest values regarding number of leaves/plant, stem diameter and leaf area, number of roots/plant in both seasons, fresh weight of roots in the 2nd season and dry weight of root, fresh and dry weight of shoots, number of both shoots and flowers/plant in both seasons. The interaction treatment between spraying plants with GA3 at 200 ppm and 2 g/l microelements mixture gave the tallest plants in both seasons. However, the interaction treatment between Kin at 100 ppm and spraying plants with 3 g/l microelements mixture was the best interaction treatment for enhancing the concentration of total chlorophyll and total carbohydrates in shoots, in both seasons. Generally, the best interaction treatments for increasing growth, flowering and biochemical constituents was obtained with Kin at 100 ppm and 2 g/l microelements.}, keywords = {Spathiphyllum wallisii,gibberellic acid,kinetin,microelements mixture,Vegetative growth,Chemical composition}, url = {https://sjfop.journals.ekb.eg/article_31468.html}, eprint = {https://sjfop.journals.ekb.eg/article_31468_cfdf970c15c02ff86bbf033e4eaafe5a.pdf} } @article { author = {El-Shawa, Ghada and Elzohiry, Nahla}, title = {MITIGATION THE HARMFUL EFFECT OF IRRIGATION WATER SALINITY ON ROSA HYBIRIDA, CV.

So, the main purpose of this investigation was to study increasing resistance of Rosa hybirida cv. Centrix to irrigation with diluted sea water by using arginine and magnetic iron. The experiment was conducted on Rosa cv. Centrix during the two successive seasons of 2016 and 2017 to evaluate the effects of foliar spraying with arginine at (100 and 200 mg L-1) and soil application with magnetic iron at (4 and 6 g pot-1) were studied combined with irrigation by diluted sea water at three concentrations (5, 10 and 15%) on vegetative growth, floral and chemical parameters. The results showed that plant height, number of branches, number of leaves, leaf area, fresh and dry weights of leaves as well as floral characters such flowering stem length, number of flowers, flower diameter, flower fresh and dry weights were increased at lower levels of salinity of diluted sea water irrigation (5%), and then gradually decreased with increasing irrigation water salinity from 5 to 15% as compared to non-saline water (control). Moreover, relative water content, photosynthetic pigments, reducing sugars, mineral uptake (N, P, K, Mg and Ca %) were negatively affected by salt stress while increasing electrolyte leakage (%), proline and total sugars as well as higher contents of Na+. In contrast to this, arginine or magnetic iron ameliorated all parameters in plants which were irrigated with all diluted sea water concentrations. It could be noticed that the application of arginine at 200 mg L-1 or magnetic iron at 6 g pot-1 could partially alleviate the harmful effect of salinity stress on plant growth and biochemical constituents of Rosa cv. Centrix plant. From the obtained results, it could be recommended that spraying Rosa plants irrigated by diluted sea water with arginine at 200 mg L-1 could overcome the deleterious effects of salinity.}, keywords = {Rosa hybirida,salinity stress,Arginine,Magnetic iron}, url = {https://sjfop.journals.ekb.eg/article_48681.html}, eprint = {https://sjfop.journals.ekb.eg/article_48681_646c108f329aeb7593529b0b8d5d30b9.pdf} } @article { author = {Goda, S.A.M.

Results could be briefed in the following: watering at 2 weeks seems to be more effective in increasing the values of most studied characters. On the other hand, both moringa extract and ascorbic acid resulted in the highest values of studied characters. Regarding combination between irrigation intervals and different bio- and chemical materials, all untreated control plants irrespective of their watering regime, in addition to plants watered at 4 weeks interval and treated with either moringa extract or potassium silicate, did not flower at all over the period of this study. Meantime, the same plants recorded the lowest values of many characters irrespective of the watering regime. Plants treated with moringa extract and watered at 1 week interval had the highest values of flower diameter, number of branches, root length and root fresh weight. Those watered at 2 weeks interval achieved the highest rank of number of leaves and flowers, flower diameter, fresh and dry weight of flowers, P%, K% and total chlorophyll content. Plants treated with ascorbic acid combined with irrigation at 2 weeks interval got the highest records of plant height, stem length, leaf length, fresh weight ofleaves, stem fresh and dry weights, total chlorophyll and carotenoids content. In conclusion it is recommended to irrigate Euphorbia milii var. longifolia grown in 25 cm plastic pots at 2 weeks interval, combined with treating plants with either moringa extract or ascorbic acid in order to get the best results.}, keywords = {Euphorbia milii var. longifolia,Irrigation intervals,moringa extract,potassium silicate,Salicylic acid,ascorbic acid}, url = {https://sjfop.journals.ekb.eg/article_52365.html}, eprint = {https://sjfop.journals.ekb.eg/article_52365_bcc9e615a1963a6b94258a13ab3cb915.pdf} }
