Beschreibungen/Notizen
The present investigation studied the effect of two doses of gamma -rays (20, 40 Gy) or foliar spraying of jasmonic acid 0.2 and 0.3 mu M on moringa plants under salt stress condition (4000 mg/L NaCl). Foliar spray by jasmonic acid especially (0.3 mu M) gave the highest peroxidase and polyphenol oxidase enzymes activity under normal or stress condition. Gamma rays and jasmonic acid treatments caused changes in activities, the band concentration of peroxidase and polyphenol oxidase isozymes and increased amino acid contents. Under salt stress condition, Cl, Fe, K and Na percentage increased significantly and of Ca, Mg and S decreased. The greatest level of K were also observed in samples treated by gamma -rays or sprayed by JA under normal or salt stress condition. Gamma irradiation with dose 20 Gy and spraying with jasmonic acid (0.3 mu M) increased moringa resistance to salt stress during growth under 4000 mg/L level of salt stress.
