Abstract:
نفذت هذه الدراسة في قسم علوم الحياة - كلية التربية للعلوم الصرفة للموسم الشتوي 2014 - 2015 لبيان دور الرش بالجبرلين وحامض السالساليك والبوتاسيوم في زيادة تحمل صنفين من الحنطة للاجهاد الملحي.تضمنت الدراسة رش الجبرلين وحامض السالساليك والبوتاسيوم بالتراكيز | This study carried out in the department of Biology - College of Education for pure science in winter season 2014 - 2015 to indicate the role of spray by of gibberellien and salicylic acid and potassium in increased tolerance of two wheat cultivars to salt stress.The study included spray of gibberellien and salicylic acid and potassium with the concentrations of 200, 100 and 3000 mg.Liter - 1 on the vegetative of two wheat varieties Rashid and Diglha to increase the tolerance to the two levels of soil salinity and which are 3 and8 ds.m - 1.Through study of some morphological and physiological traits (germination rate, speed germination coefficient, number of tillers, flag leaf area, plant height, chlorophyll content, proline content, sodium and potassium rate securities, number of spikes, number of spikelet, spike length, grain protein ratio, weight of 1000 grain and grain yield).The results showed that increasing the level of soil salinity led to obtain significant decrease in the most of the traits, the study also showed adiscrepancy between the two cultivars, it was the product growth indicators Rashid best of Diglha and for most of the traits. Where spraying potassium gave the best results for most of the traits through reduce the negative impact of salt stress on plant wheat more than spraying gibberellien and salicylic acid. The study showed that the treatment of spraying potassium it was superior in most of the traits results and of these qualities is the description of the number of tillers where recorded 19.3 branch. Plant - 1 and recipe flag leaf area where the 28.20cm2 and the recipe chlorophyll content 88.181 spad and prescription rate securities where sodium ratio 0.151% and in the number of spikes reaching 14.8 spike. Plant - 1 and the average number of spikelet which is 21.0 spikelet. Spike - 1 and the percentage of protein in grain 18.1% and grain yield reaching 11.497 gm. Planter - 1.
