| Abstract This experiment was carried out in the laboratories during 2012، to measure the ratio of seedling emergence in the first count and standard count، length and weight of radical، and length and weight، of plumage. A Complete Randomized Design (CRD) was used in the experiment، by two factors، different soaking treatments (without soaking ، soaking with 30 ppm proline acid + 200 ppm gibberellic acid، soaking with 30 ppm proline، and soaking with 200 ppm gibberellic)، different salinity levels of irrigation water which involved (1.2 ، 3، 6، 9، 10 ds.m¯¹). Seeds were soaked in the acidic solutions for 24 hour، then implanted in the small plastic containers filled with about glass sand (depth of 10 cm) then irrigated with water incubated at 25±5 C° temperature. The study showed Increased salinity of irrigated water caused a significant decrease in all studied prameters in this experiment، the results showed that the highest mean of implantation (78.21%، 96.29%) was recorded in the first and standard count، the highest mean of length (17.24cm، 19.48cm) and weight of radical and plumages (6.56mg، 65.7mg)، The lowest mean of Proline acid content in the seedling (3.425 mmol/L) were recorded in the irrigation water salinity of 1.2 dS.m-1 level. The levels of proline acid of the seedlings were increased significantly with increasing of irrigation water salinity، which reached the highest mean of 4.167 mmol/L. at salinity level of 10 ds.m-1.The Proline soaking treatment led to a significant increase in the ratio of implantation of first and standard count، length and weight of radical، length and weight of plumages and contend of Proline in the seedling، The increasing percentages were (33.63%، 73.93%، 47.97%، 27.16%، 34.52% 19،73% and 29.73% respectively).Soaking with gibberellic acid treatment had superior increase compared to the implantation without soaking، the soaking with gibberellic+proline acid treatment in the ratio of first and standard count (63.17، 71،76%)، length and weight of radical (17.19cm، 3.88mg)، length and weight of plumages (17.50cm، 57.1mg)، Prolin content (3.670 mmol/L ). | ||
