“…Exogenous MeJA to peach (Prunus persica) was proved to be useful to defend against high temperature shocks, while eliciting an advantageous response similar to high temperature shocks, but without the undesirable effects or damage to the fruits that stress may cause (Budde et al 2005). More recently, exogenous MeJA was discovered to be useful in improving cold tolerance, by increasing endogenous trans-zeatin (t-Z), and indole-3-acetic-acide (IAA) in contrast decreased ABA level in maize (Battal et al 2008).…”

Because of its prolific growth, oilseed rape (Brassica napus L.) can be grown advantageously for phytoremediation of the lands contaminated by industrial wastes. Therefore, toxic effect of cadmium on the germination of oilseed rape, the capability of plants for cadmium phytoextraction, and the effect of exogenous application of plant growth regulators to mitigate phytotoxicity of cadmium were investigated. For the lab study of seedlings at early stage, seeds were grown on filter papers soaked in different solutions of Cd 2? (0, 10, 50, 100, 200 and 400 lM). In greenhouse study, seedlings were grown in soil for 8 weeks, transferred to hydroponic pots for another 6 weeks growth, and then treated with plant growth regulators and cadmium. Four plant growth regulators viz. jasmonic acid (12.5 lM), abscisic acid (10 lM), gibberellin (50 lM) and salicylic acid (50 lM); and three levels of Cd 2? (0, 50 and 100 lM) were applied. Data indicated that lower concentration of Cd 2? (10 lM) promoted the root growth, whereas the severe stresses (200 or 400 lM) had negative effect on the establishment of germinating seedlings. Plants treated with any of the tested plant growth regulators alleviated cadmium toxicity symptoms, which were reflected by more fresh weight, less malondialdehyde concentration in leaves and lower antioxidant enzyme activities. The application of abscisic acid to the plants cultivated in the medium containing 100 lM Cd 2? resulted in significantly lower plant internal cadmium accumulation.

In this work, a boron-doped diamond (BDD) electrode was used for the electroanalytical determination of indole-3-acetic acid (IAA) phytohormone by square-wave voltammetry. IAA yielded a well-defined voltammetric response at + 0.93 V (vs. Ag/AgCl) in Britton-Robinson buffer, pH 2.0. The process could be used to determine IAA in the concentration range of 5.0 to 50.0 mM (n = 8, r = 0.997), with a detection limit of 1.22 mM. The relative standard deviation of ten measurements was 2.09 % for 20.0 mM IAA. As an example, the practical applicability of BDD electrode was tested with the measurement of IAA in some plant seeds.

“…The maize (Zea mays) is one of the most important crops, and adaptation of this plant to early annual planting dates requires improvement of chilling tolerance (Battal et al 2008). One of the major problems arising in some maize cultivation areas includes different levels of injuries caused by lower temperatures in early spring.…”

Low temperature is one of the major adverse climatic factors that suppress plant growth and sustainable agricultural development. In these climate conditions, silicon (Si) can mitigate various abiotic stresses including low temperature. In this study, the roles of foliar-applied silicon (10 mM potassium metasilicate) in enhancing tolerance to chilling stress were investigated in maize (Zea mays 'Fajr') plants. The low temperature stress caused significant reduction of plant growth and relative water content; however, Si ameliorated these effects. Si supply in maize exhibited a significantly positive effect on accumulation of free amino acids, and reduced the necrotic leaf area. The decrease in maximum quantum yield of PSII (F v /F m ) was reversible during recovery, but not in the non-Si-treated leaves. This can be explained by enhancement of protective pigments; carotenoid and anthocyanin leading to the protection of PSII from damage. Additionally, analysis of OJIP transients revealed that Si reduced cold damaging effect on performance index (PI abs ) and F v /F m through improvement of excitation energy trapping (TR 0 /CS) and electron transport (ET 0 /CS) per excited crosssection of leaf. The malondialdehyde (MDA) concentration, which was significantly increased under chilling stress, was decreased by Si. The reduced glutathione and ascorbate concentrations were higher in Si-treated plants as compared to those without application of Si under chilling stress. These results indicated that Si could enhance the chilling stress tolerance of maize plants through improving the biomass accumulation, maintaining a high level of glutathione, ascorbic acid, protein, protective pigments, and enhancing the photochemical reactions. This study also suggests that the foliar-applied Si increases recovery ability from chilling injury. Nizka temperatura je eden izmed glavnih neugodnih klimatskih dejavnikov, ki zavira rast rastlin in trajnostni razvoj kmetijstva.V takšnih klimatskih razmerah lahko silicij oblaži abiotski stress vključno z učinki nizke temperature. V tej raziskavi je bila preučevana vloga foliarnega dodajanja Si (10 mM kalijevega metasilikata) pri povečevanju odpornosti koruze (Zea mays 'Fajr') na hladni stres. Stres zaradi nizkih temperature je značilno zmanjšal rast in vsebnost vode v rastlinah, kar je dodajanje Si oblažilo. Dodatek silicija je sprožil v koruzi značilne pozitivne učinke v kopičenju prostih amino kislin in v zmanjšanju nekrotičnosti listov. Zmanjšanje v fotokemični učinkovitosti PS II (F v /F m ) je bilo povratno med okrevanjem, vendar ne pri rastlinah, ki niso bile tretirane s silicijem. To bi lahko razložili s povečanjem vsebnosti zaščitnih pigmentov karotenoidov in antocianinov, kar vodi v zaščito PSII pred poškodbami. Dodatno so analize prehodne fluorescence klorofila a (OJIP) odkrile, da je dodatek Si zmanjšal učinek poškodb zaradi hlada na fotosintetski elektronski transport (PI abs in F v /F m ) preko boljšega prestrezanja ekscitacijske energije (TR 0 /CS) in boljšega elektronskeg...
