The effect of water deficit stress and salicylic acid application on physiological characteristics of sweet corn (Zea mays var. Merit), an experiment was conducted. Treatments were water deficit stress in three levels: a1: normal irrigation (100% FC irrigation), a2: fair stress (75% FC irrigation) and a3: mild stress (50% FC irrigation). The second factor was the 0/1 mM salicylic acid application in six levels [b1: control, b2: seed priming, b3: SA application in 3 leaves stage, b4: SA application in pollination stage, b5: seed priming + SA application in pollination stage and b6: SA application at 3 leaves stage + pollination stage. The analysis of variance showed significant effect of interaction between water deficit stress and SA application on Chl. a, Chl. b, Chl. a + b, 100-grain weight and ear yield (p < 0.01). Results showed that SA application at 3-leaves stage + pollination stage indicated five times more Chl.a as compared with control in 50% FC irrigation. SA application at 3-leaves stage proved 4/2 and 4/4 times more Chl.b and Chl. a + b as compared to control in mild stress. SA application at pollination stage had the highest (36/15 g) and control at mild stress had the lowest (10/56 g) 100-grain weight. Also, SA application at 3-leaves stage + pollination stage had the highest (245/1 g/plant) and control at mild stress had the lowest (74/25 g/plant) ear yield.

Due to low rainfall at early autumn, smooth vetch seedling growth in rain-fed lands often is limited by water deficit stress yet the data regarding the reactions of smooth vetch to water deficit at early growth stages are pretty rare. The objective of current study was to examine possibility of using priming treatments (hydro priming and priming salicylic acid) to alleviate the inhibitory effect of water deficiency during early growth of Smooth Vetch. In this respect, seeds were soaked in distilled water (hydro priming) or 0.5 mM solution of SA for 36 h at 10 °C then dried back to original moisture content. Pots were irrigated for 25 days at four levels of available water containing field capacity (FC), 75% FC, 50% FC and 25% FC. In general, seedling emergence and early growth were markedly limited by increasing water deficiency. However, priming treatments particularly with SA caused considerable improvement in either emergence or growth of seedlings (dry weight, length). The obtained results showed that primed samples exhibited higher accumulation of proline, glycine betaine (GB) under all levels of available water except 100% FC and also higher total soluble sugars (TSS) and trehalose under severe water deficit (25% FC). SA primed samples had higher relative water content especially under higher levels of water deficiency. The more balanced water status within SA primed samples also was accompanied with higher accumulation of proline and glycine betaine. There were significant differences between two priming treatments in terms of proline and GB content within seedlings and SA priming considerably increased proline and GB accumulation. In contrast to proline and GB, TSS and trehalose content wasn’t influenced by SA treatment and both hydro and SA primed samples showed statistically similar quantities.

Randomized Design

Impacts of various concentrations of salicylic acid (SA) on cucumber (Cucumis sativus L.) seedling characteristic were evaluated under different water stress levels by using a factorial arrangement based on completely randomized design with three replications at experimental greenhouse of Ferdowsi University of Mashhad, Iran. The studied factors included three water deficit levels (100% FC, 80% FC, and 60% FC) considered as first factor and five levels of SA concentrations (0, 0.25, 0.5, 0.75, and 1 mM) as second factor. Results showed that foliar application of SA at the highest concentration enhanced leaf area, leaf and dry weight while decreased stomatal conductance under high level of water deficit stress. Though, severe water deficit stress sharply raised the SPAD reading values. In general, exogenous SA application could develop cucumber seedling characteristic and improve water stress tolerance.
