Abstract: 

Plants deal with different stresses including biotic and abiotic stresses during their life. The stresses affect germination and growth of plants. Heavy metals such as cadmium in soil could decrease seed germination and growth of plants. It has been found that salicylic acid is able to reduce negative effects of the heavy metals on different aspects of plant life. The current research was carried out to evaluate probable positive effects of salicylic acid on germination and initial growth properties of B. tomentellus when facing with cadmium stress. For this purpose, an experiment including B. tomentellus seeds pretreatment with 0, 100, 200 and 300 mg/L levels of salicylic acid for 10 hours was conducted. Also, stress condition was prepared using cadmium levels of 0, 10, 20 and 30 mg/L. Results indicated that cadmium decrease germination percentage, rate of germination, radicle and plumule length while using salicylic acid inhibit negative effects of cadmium. Germination percentage and radicle length showed the highest one when 200 and 300 mg/L of salicylic acid was used, respectively.
