Production of proline and other biochemicals as stress measures in mycorrhizal, biotic and abiotic factors in Luffa cylindrica

Luffa is a genus of tropical and subtropical vines in the cucumber (Cucurbitaceae) family. Proline and other biochemical parameters effect was evaluated on bottle gourd (Luffa cylindrica (L.) Roem) in control, mycorrhizal and other biotic and abiotic soil components treated plants. Higher proline concentrations reflected in leaves of treated plants as compared with mycorrhizal treated plants. The decrease in shoot length, number of leaves and leaf area were observed in non mycorrhizal and plant treated with other biotic and abiotic stresses. Higher amount of proline was produced in non mycorrhizal and stressed plants in result of reduced availability of water and dry matter translocation to the shoots. The proline contents of Luffa leaves showed a vast difference in different treatments. It may be concluded here that proline is an indicator of environmental stresses imposed on plants.
