| Abstract | ||
| A experiment was conducted at the Department of Horticulture – Agriculture College –Baghdad University . during two seasons of 2013 – 2014 to Diagnosis and testing of genetic and physiologic variable in tomato Lycopersiconesculantum .Mill under salt stress conditions . It have been used tomato seeds for Red ston seeds for sprouted were soaked in distilled water for 8 hours then conducted the following treatment in Sodium azide (NaN3): seeds sprouted soaked in sodium azide solution and Electric Shock treatment Sodium azid interaction with electric shock treatment in first season planting in three levels of water salinity 1.9, 4, 8 dsm. in second season individual plant selection planting in two levels of water salinity 2, 8 dsm ˉ¹. Nested Design was used with three replicated .first season The results showed that4SA+6A treatment significantly increased plant length (77.11)cm . 6A and 3A increased number of plant main shoots . 4SA+3A treatment significantly increased leaf area at( 630.71) dsm² .chlorophyll content increased in 2SA+3A at 365.29mg.100 fresh weight . 12A treatment significantly increased number of fruits(15.06) fruit .plant ˉ¹ and plant yield (1.49 )kg .plantˉ¹ .while fruit weight increased significantly in 3A treatment, (105.80)grams The results showed plant length increased in C3 level of saline water stress in first season . number of main shoots and leaf area increased in C1 level in two seasons. number of fruits increased in C3 level of saline water stress (12.08) fruit .plant ˉ¹ in first season while in second season increased in C1 level , fruit weight and plant yield increased in C1level of saline water stress in two seasons. | ||
