Abstract Faba bean is an important legume crop; it is the principal protein source for poor people in some Asian and African countries. Salinity stress is one of the main abiotic stresses that limits plant growth, crop productivity and yield quality. Present study aimed to investigate different responses of two Faba bean varieties (Sakha-3 and Giza-716) to two used levels of NaCl (50 and 100 mM) and exogenous application of Folic acid (FA), Royal jelly (RJ) and 5-azacitidine (5-AZA) as well as their combinations treatments. The present investigation aimed also to determine germination %, shoot and root lengths, fresh and dry weights, photosynthesis pigments, rate of electrolyte leakage (EL), Lipid peroxidation product (MDA), changes in separating pattern of total soluble protein, mitotic index, chromosomal aberrations were also studied. On the other hand changes in the expression levels of some antioxidant enzymes encoding genes (SOD, CAT and GR) as well as some protection and growth related proteins (HSP-17.9 and GPRP) and two DNA methyltransferases encoding genes (MT1 and MT2) were also evaluated using quantitative real time PCR. The obtained results showed that, salinity stress induced a reduction in most of studied parameters such as root and shoot lengths, fresh and dry weights, germination % and mitotic index. |
