| Abstract | ||
| Salinity is considered one of the main reasons for the decrease in growth and flowering characteristics of various ornamental species. Jatropha is a woody shrub that is widely used in modern landscaping due to the flower beauty, but its growth and development was adversely affected by salinity. To achieve the sustainable agriculture, enhancing the salt stress tolerance via eco-friendly applications is of great interest. Although reports declare that moringa leaf extract (MLE) is involved in salt-stress tolerance, little information exists about the impact of MLE on ornamental shrubs, especially jatropha under salinity conditions. This experiment was, therefore, carried out to study the impact of MLE on salinity resilience in Jatropha. Plants were exposed to 0, 30, 60 and 90 mM of NaCl, and/or foliarly sprayed with MLE at 1:30 (v:v). Salt stress markedly decreased growth and flowering parameters, total chlorophyll content and nitrogen, phosphorus, and potassium contents in the leaf tissues; however, MLE treatment alleviated these impacts. Moreover, MLE application enhanced the accumulation of proline resulting in the mitigation of salinity damage. The current results revealed the possible benefits of the application of MLE and its mechanisms that can improve the growth and flowering of jatropha shrubs under salinity. | ||
