Antioxidative response in two Rubus species exposed to salinity
Salinity is considered as one of the serious abiotic factors that inhibits plant growth and development. Excessive salt concentration in the soil has negative impact on germination and yields and causes enormous damage in overall economic output. In nature salinity is often present in soils which are concurrently affected by drought and/or heat stress. The aim of this work was to investigate the influence of the salt stress in two Rubus species (Rubus ideus L. var. Himbo top and Rubus fructicosus L. var. čačanska Bestrna) through proline content, level of lipid peroxidation and activities of antioxidative enzymes. Plants were exposed to NaCl (15 and 35 mM) in in vitro conditions for 21 days. In red raspberry salinity (35 mM NaCl) induced remarkably increased catalase (CAT) and ascorbate peroxidase (APX) activities while blackberry showed high guaiacol peroxidase (POD) activity indicating their important role in elimination of reactive oxygen species (ROS). Malondialdehyde (MDA) content showed an increase at 15 mM NaCl while the highest NaCl concentration (35 mM) caused decline in MDA content, in both Rubus species. Decreased proline synthesis in both Rubus suggested that proline is not involved in antioxidative response induced by NaCl.
