Abstract<\/strong><\/p>\n\n\n\n

The salinity in arid and semi-arid regions is one of\nthe most important problems that negatively affect plant growth and\ndevelopment, especially at the germination and seedling stages. An experiment\nwas carried out in pots at the laboratories of the Field Crops Department at\nthe Faculty of Agricultural Engineering in Deir Ezzor\/Euphrates University\nduring 2016\/2017 agricultural season. Therefore, the study aimed to know the\nrole of gibberellic acid in increasing the efficiency of germination and growth\nof yellow corn seeds (Zea mays<\/em> L.) cultivar (Ghouta-82) under saline\nstress. The first treatment was the use of saline with different concentrations\nof sodium chloride (5000, 6000, 7000 and 8000) mg\/l, in addition to the treatment\nof soaking with distilled water (control), and the treatment of soaking the\nseeds with gibberlic acid GA3 (300) mg\/l. The experiment was laid out according\nto the completely randomized design, with three replications. The number of\npots was (30), where each pot represents a treatment. The results showed\nsignificant differences in the effect of sodium chloride concentration on all\nstudied characteristics (germination percentage, germination strength,\nseedlings and root length, leaf area and total chlorophyll) which decreased by\n74.33, 76.53, 60.23, 42.34.11, 78.86, 59 and 81)%, respectively, also, there\nwas a significant increase in the period required for germination, and the\npercentage of (K +) \/ (Na +) by (61.25 and 61.11)% in the treatment with a\nconcentration of (8000) compared to the treatment of the control (distilled\nwater), in addition to a significant decrease in the treatment of soaking the\nseeds with GA3 at a concentration of (300) mg\/L for both; germination speed and\n(K + \/ (Na +) ratio of (28.57 and 23.63)%, respectively, and a significant\nincrease in germination indicators was noticed, where strength, seedlings and\nrootstock length, (K + \/ (Na +) ratio, leaf area and total chlorophyll by\n(16.66, 61.87, 39.13, 66.67, 72.02 and 75.48)%, respectively, compared with the\ntreatment of non-soaking seeds with GA3. Also, the results showed a significant\neffect of the interaction between salt concentrations and soaking the seeds\nwith GA3 on the one hand, and on the other hand between salt concentration and\nsoaking the seeds with distilled water (control) on all studied traits of\nyellow corn, cultivar (Ghouta-82).<\/p>\n\n\n\n
