“…Likewise, Ashraf and Foolad (2007) reported that the effectiveness of PRO applied as a foliar spray depended on the concentration, time of application, type of species, and plant developmental stage. Shahid et al (2014) recorded that the effect of exogenous PRO on stress damages was dependent on the concentration, and foliar-applied PRO at a low concentration reduced the oxidation of lipid membranes in Pisum sativum under salinity-stressed conditions. In our study, to the best of our knowledge, it has been shown for the first time that exogenous PRO application in rooting medium and seed soaking modes alleviated the hazardous effects of drought stress on membranes in maize plants.…”

Exogenous proline (PRO) at low concentrations can enhance drought stress tolerance in different application modes such as application to rooting medium, foliar spray, and seed soaking. However, there is no information about which application mode is more effective for increasing the drought tolerance. Comparative effects of 1, 10, and 20 mM PRO applications through three application modes to hydroponically grown seedlings were examined under short-term drought stress in maize seedlings. Effects on leaf water potential, membrane damage, chlorophyll content, proline level, and gas exchange parameters such as net photosynthetic rate (Pn), transpiration rate (E), stomatal conductance (gs), and substomatal CO 2 concentration (Ci) were compared. Results indicated that PRO pretreatments raised the water potential, chlorophyll content, Pn, E, gs, and Ci but lowered the malondialdehyde content in the three application modes as compared to the untreated plants. Of the three different modes of PRO pretreatment, rooting medium treatment at 1 mM concentration was also more effective in alleviating stress-induced damages in maize seedlings. Moreover, effectively applied PRO increased the maximum quantum efficiency of PS II, quantum yield of PS II photochemistry, photochemical quenching, and electron transport rate but decreased nonphotochemical quenching of chlorophyll fluorescence under short-term drought stress. In conclusion, exogenous PRO was markedly more effective in the root-treated mode than in foliar spray or seed soaking mode, suggesting that PRO had a different ameliorating effect in different application modes. Proline application in an effective mode can induce photochemical efficiency under short-term drought in maize.

“…In another experiment, pea plants were exposed to NaCl and/or NiCl 2 stress to investigate whether pure Pro or Pro enrichedleaf extract of Lolium perenne L. could effectively protect against phytotoxicity. Natural Pro (leaf extract) containing other essential nutrients proved to be a better protecting agent than pure Pro by altering the polyamine metabolism (Shahid et al, 2014). 7.5.…”

Proline (Pro) accumulation is a common response of several plant species to combat abiotic stresses. Under stress conditions, Pro acts as an excellent compatible solute in the plant system, participating in the alleviation of stress sensitivity. Though the metabolic pathways associated with Pro are well studied, parts of its regulatory cascades are still not properly known. It has also been conjectured that epigenetic modifications regulate Pro metabolism during abiotic stress. Apart from Pro, the plant abiotic stress responses are essentially mediated by multiple effectors. Hence, proper analysis of the cross-talks of Pro with the other components of the abiotic stress response has turned out to be mandatory in order to design multistress-tolerant transgenic lines. Highlighting the relation between Pro and seed germination is also essential to understand the notion behind plant susceptibility and survival during stress. Generally, Pro has a universal mechanism to generate abiotic stress tolerance through stabilization of structural components, enzyme structures, and regulation of osmotic adjustments. The success achieved through recent transgenic approaches leading to more accumulation of Pro in the sink has also been focused on in the present review.

The presented paper deals with monitoring of the ways of selenium (Se) content increase by foliar biofortification with inorganic Se in two varieties of garden pea Pisum sativum L. (Premium, Ambassador) in the conditions of south Slovakia in 2014-2015. The results of experiments show that treatment of plants with two doses of Se concentration (50 g and 100 g Se ha -1 in the form of a sodium selenate anhydrous solution) at the flowering stage significantly increased the total Se content in the seeds of both varieties. Following the results by the consumption of 25 g of dried seeds of peas or 100 g of fresh pea seeds after the biofortification with 100 g Se ha -1 a recommended daily dose of Se in humans may be covered. The significantly positive influence of Se application on the total polyphenols content (TPC) has been confirmed in the both varieties after application of dosage in 100 g Se ha -1 (52% and 33%). A significant increase in the average value of total antioxidant capacity (TAC by DPPH method) in garden pea var. Ambassador was observed after the application of both doses of Se, in case of Premium variety only after application with a 100 g Se ha -1 . Significantly increasing level of TAC by PCL (photochemiluminescence) method was found out only in case of var. Premium.
