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.
