Abstract
This recent study aimed to evaluate the impact of petroleum-contaminated soil on the growth and productivity of seven alfalfa (Medicago sativa L.) genotypes. Three levels of petroleum contamination were used (zero, 40, and 60ml.kg-1). A range of morphological and physiological traits were assessed, including germination percentage, tolerance index, chlorophyll content, plant height, dry weight, and survival rate. The obtained results indicated that petroleum stress significantly reduced most measured traits, with the highest impact observed at the 60 ml kg-1 level. Tolerance index and chlorophyll content were reliable indicators of genotype resilience. A strong genotype × environment interaction was observed due to a significant interaction between genotype and the level of contamination. However, genotypes such as “Rammah” and “Australian” presented a notable resilience to petroleum contamination, since they maintained a relatively higher performance under stress. Therefore, it was assumed that these two genotypes might be utilized in selective breeding for phytoremediation and soil restoration programs.
