| To evaluate the effects of different temperature and salinity level on seed germination characteristics and growth characteristics of tomato (local variety, kurdi)(V1), person (V2) and sun (V3) ), 2 varieties of eggplant (local Kirkuk (V1) and Linda F1(V2)) and 2 varieties of pepper (California wonder (V1) and Pepper Kilfass (V2)) seed, 3 different temperature and 4 NaCl concentrations were used, T1: 20 ºC with 0 mM NaCl, T2: 20 ºC with 50 mM NaCl, T3: 20 ºC with100 mM NaCl, T4: 20 ºC with 150 mM NaCl, T5: 25 ºC with 0 mM NaCl, T6: 25 ºC with 50 mM NaCl, T7: 25 ºC with 100 mM NaCl, T8: 25 ºC with 150 mM NaCl, T9: 30 ºC with 0 mM NaCl, T10: 30 ºC with 50 mM NaCl, T11: 30 ºC with100 mM NaCl And T12: 30 ºC with 150 mM NaCl, the germinated seeds and growth traits were measured. The results show that there were different response of varieties to different temperatures, in most of the three types of vegetable seeds using of 25 °C recorded better results as compared to other temperature regimes. Results revealed decreased in germination traits on tomato and pepper seeds when salinity increases, A low contamination concentration has little negative effect on the seeds germination. Increase of NaCl concentrations caused a significant reduction in germination percentage, germination rate, and root and shoots length and weights of the three vegetables. In conclusion: Local varieties of tomato and eggplant more resistant to changing in NaCl levels and temperature regimes contamination of high concentration of NaCl in seed germination media restricted the germination but results revealed that using of 25 °C help the plants for resist the high concentration of NaCl. | ||
