Abstract:
نفذت التجربة في الموسم الشتوي للعام (2012 - 2013) م في احد الحقول التابعة لناحية الحر في محافظة كربلاء, لمعرفة استجابة نبات السلق للشد الملحي والرش بحامضي البرولين والجبرلين والتداخل بينهما في بعض الصفات الكمية والنوعية لبعض الاجزاء الخضرية والتكاثرية (ا | An experiment was conducted in the winter season of the year (2012 - 2013) in a private Al - Hur district in Karbala governorate, to find out chard plant response to salt stress, proline and gibberellic acids and their interaction on some quantity and quality characteristics to some parts of vegetative and reproductive (leaves, flowers and seeds) to chard plant (Beta vulgaris var. cilca L.).The design of the experiment was randomized complete blocks (RCBD) in a factorial arrangement with three replicate. The first factor was four levels of saline water (0(River water), 2, 4 and 6) ds. m - 1 and the second factor was seven concentration of proline acid (PA) and gibberellic acid (GA3) (0(River water), 50PA, 100PA, 150PA, 50GA3, 100GA3 and 150GA3) mg. L - 1. Means were compared by using averages revised least significant difference (RLSD) at 0.05 probability level when the treatments referred to significant effect. The results showed : 1 - The negative effect of salinity levels on the qualities of the vegetative plant chard before flowering stage with the except of the dry weight of the root system, which had increased significantly with the level of salinity 2 ds. m - 1.2 - The negative impact of salinity levels in vegetative qualities of chard plant after flowering except root length, leaves chlorophyll content (a, b and total), nitrogen%, protein% and proline which increased with the level of salinity 2 ds. m - 1. as well as the potassium% in leaves with a salinity level 4 ds. m - 1 and dry weight of shoots with all levels of salinity and especially 6 ds. m - 1.3 - Gibberellic acid was dominant on proline acid in terms of chard plant by 150 mg. L - 1 concentration before flowering and 50 mg. L - 1. concentration after flowering while proline acid was dominant on gibberellic acid in dry weight before flowering and root dry weight of shoots after flowering, by 50 mg. L - 1 and potassium% in leaves and the protein% with 100 mg. L - 1 concentration.4 - The interaction between the salinity levels and acids concentrations add showed a significant difference in most of the traits of the plant, especially in combinations consisting of level 2 ds. m - 1 or comparison of saline with gibberellic acid by 150 mg. L - 1 before flowering and 50 or 100 mg. L - 1 after flowering while gave a combination of salinity level 4 ds. m - 1 with concentration of proline acid 100 mg. L - 1 higher of potassium% in leaves
