“…The responses of antioxidant enzymes to UV radiation vary among plants species ) Tossi et al, 2009;Salama et al, 2011;Czégény et al, 2016(. The increasing in the activities of antioxidant enzymes could be the indicator of build-up of a protective mechanism to reduce oxidative damages induced by stress (Harinasut et al, 2003;Chawla et al, 2013).

Decline in ozone layer that followed by enhanced solar UV radiation is a limiting factor for some plants. In this study the effect of UVA+UVB radiation on parsley plant was studied hydroponically at different concentrations of Zn (1.5 and 6.5 µm). UV radiation at both concentrations of Zn, slightly decreased the plant growth and significantly increased the carotenoids, flavonoids, total phenols and H 2 O 2 contents, but had no effect on chlorophylls content. At concentration of 1.5 µm of Zn, UV radiation caused significant increases in the MDA and anthocyanin contents and the activities of POD and CAT enzymes, but decreased the soluble sugars and protein contents. At concentration of 6.5 µm of Zn, UV radiation caused significant increases in the CAT activity, but had no significant effect on other parameters. Results suggest that parsley plant tolerates UVA+UVB radiation particularly at concentration of 6.5 µmof Zn.Key words: antioxidant enzymes; parsley; photochemicals; UVA + B; Zn IZVLEČEK OBRAVNAVANJE Z UVA + UVB VPLIVA NA ANTIOKSIDACIJSKI SISTEM IN KEMIZEM PETRŠILJA PRI RAZLIČNIH KONCETRACIJAH ZnTanjšanje ozonske plasti, ki mu sledi povečano UV sončevo sevanje sta omejujoči dejavnik za nekatere rastline. V tej raziskavi je bil preučevan učinek UVA+UVB sevanja na hidroponsko gojen peteršilj pri različnih koncentracijah Zn (1.5 in 6.5 µm). UV sevanje je pri obeh koncentracijah cinka rahlo zmanjšalo rast in značilno povečalo vsebnost karotenoidov, flavonoidov, celokupnih fenolov in H 2 O 2 , a brez učinka na vsebnost klorofilov. Pri koncentraciji 1.5 µm Zn, je UV sevanje povzročilo značilno povečanje vsebnosti MDA in antocianinov, povečalo je aktivnosti encimov POD in CAT, a zmanšalo vsebnost topnih sladkorjev in beljakov. Pri koncentaraciji 6.5 µm Zn je UV sevanje povzročilo značilno povečanje v aktivnosti CAT, a ni imelo značilnega učinka na ostale parametre. Rezultati nakazujejo, da peteršilj dobro prenaša UVA+UVB sevanje, še posebej pri koncentraciji 6.5 µm Zn.

“…These results suggest that this antioxidant enzyme has possible defensive role in the removal of H 2 O 2 under salinity stress. The increased total peroxidase activity in response to salinity has been reported (Chen et al 1993;Sreenivasulu et al 2000;Harinasut et al 2003). The plants treated with NaCl in combination with GA 3 and AsA exhibited much higher values for antioxidant enzyme activity than when NaCl was given alone.…”

“…It has been reported that ROS, including superoxide and hydrogen peroxide, are elevated with increasing the salinity, due to the imbalance in the production and destruction of ROS (Harinasut et al 2003). In the present study, the P. vulgaris seedlings responded to NaCl treatment with enhancement of H 2 O 2 content, which was higher in the roots than the shoots.…”

Effects of ascorbic acid and gibberellin A3 on alleviation of salt stress in common bean (Phaseolus vulgaris L.) seedlings

Salinity, a severe environmental factor, has limited the growth and productivity of crops. Many compounds have been applied to minimize the harmful effects of salt stress on plant growth. An experiment was conducted to investigate the interactive effects of exogenous ascorbic acid (AsA) and gibberellic acid (GA 3 ) on common bean (Phaseolus vulgaris L. cv. Naz) seedlings under salt stress. The changes of growth parameters, photosynthetic and non-photosynthetic pigments and potassium content showed that the addition of 1 mM AsA and/or 0.05 mM GA 3 considerably decreased the oxidative damage in common bean plants treated with 200 mM NaCl. The NaCl-stressed seedlings exposed to AsA or GA 3 , specifically in their combination, exhibited an improvement in sodium accumulation in both roots and shoots, as compared to NaCl-treated plants. NaCl treatment increased hydrogen peroxide (H 2 O 2 ) content and lipid peroxidation indicated by accumulation of malondialdehyde (MDA), whereas the interaction of AsA with GA 3 decreased the amounts of MDA and H 2 O 2 . In the meantime, interactive effect of these substances enhanced protein content and the activity of the antioxidant enzyme, guaiacol peroxidase, in common bean plants under salt stress. It was concluded that synergistic interaction between AsA and GA 3 could alleviate the adverse effects of salinity on P. vulgaris seedlings.

“…Mulberry is a tree species that is moderately resistant to salt stress [27]. In this study, we found that NaCl-induced salinity stress caused a marked inhibition in the growth of mulberry seedlings as evidenced by changes in the DW of new leaves, shoots, and roots; the lengths of roots and shoots; and the successive increments in leaf number.…”

Mulberry (Morus alba L.), a moderately salt-tolerant tree species, is considered to be economically important. In this study, 1-year-old mulberry seedlings cultivated in soil under greenhouse conditions were treated with five concentrations of sodium chloride (NaCl; 0%, 0.1%, 0.2%, 0.3%, and 0.5%) for 3 and 21 days. Plant growth parameters were not affected by 0.1% NaCl, but significant reductions were observed after treatment with 0.2%, 0.3%, and 0.5% NaCl. The malondialdehyde content and cell membrane stability of mulberry seedlings exposed to 0.1% NaCl did not change, indicating that mulberry is not significantly affected by low-salinity conditions. The Na contents of various organs did not increase significantly in response to 0.1% NaCl, but the K:Na, Mg:Na, and Ca:Na ratios of various organs were affected by NaCl. Marked changes in the levels of major compatible solutes (proline, soluble sugars, and soluble proteins) occurred in both the leaves and roots of NaCl-treated seedlings relative to control seedlings. Under severe saline conditions (0.5% NaCl), the ability of mulberry to synthesize enzymatic antioxidants may be impaired.
