“…Various literatures have noted the increase of leaf chlorophyll content under the influence of selenium. In accordance with the results of this study, Mozafariyan et al (2017) reported an increase in chlorophyll content of tomato leaves when the plants were fed with 7 and 10 μM of selenium. Feng et al (2013) believed that the addition of Se to the growth substrates can reduce the excess ROS generation, especially of O 2 -and/or H 2 O 2 , in plants subjected to stress.…”

Selenium (Se) is an essential micro-nutrient element for animals and human, which also has some beneficial roles in many plant species. This study aimed to evaluate the application of foliar Se on canola cultivars under different irrigation regimes. The study was carried out in two consecutive years, in the form of a factorial split plot experiment, based on an RCB design with three replications. Sodium selenate solution was sprayed on the leaves of 6 winter canola exposed to 3 different irrigation regimes. The results revealed that most of the studied traits were affected by foliar selenium, especially seed yield, seed oil yield, leaf proline content and leaf chlorophyll a content. Under drought stress conditions, foliar selenium caused a significant increase in seed yield, seed oil yield, and the relative water content of leaves. According to partial regression analysis, foliar selenium changed the nature of relationships governing the traits, especially under drought stress conditions. The results showed that, selenium reduced the effects of drought stress through improving the relative water content of the leaves. Therefore, foliar selenium can be a useful strategy to achieve sustainable agriculture, especially under water deficit conditions.

“…These results can be explained on this basis; the increases in chlorophyll content in eggplant leaves at this level of sodium selenite may be attributed to selenium overprotection effect of chlorophyll enzymes and thus, increasing the biosynthesis of photosynthesis pigments. The data are in a good harmony with those obtained by Saffaryazdi et al, (2012); Nancy and Arulselvi (2014) and Mozafariyan et al, (2017) who stated that at Se application at rate of 7 and 10 µM Se levels, increased chlorophyll content.

“…The maximum values of NO 3 concentration in eggplant leaves were obtained by Fe foliar application 41.29 mg Kg -1 . The data are in a good harmony with those obtained by Mozafariyan et al, (2017) who stated that increasing the concentration of selenium up to 10 µM led to a decrease the membrane stability index. In addition, raising levels of selenate or selenite decreased Se accumulation inside algal cells, maybe through repression of membrane transporters (Schiavon et al, 2016).…”

Eggplant is one of the most important vegetable crops with high nutritional value. So, field experiment was performed to study the effect of foliar application with iron in the form of Fe-EDTA at rate of 300 mg L -1 (923.04 g fed -1 ) and selenium as Na 2 SeO 3 (sodium selenite) at rate of 5 mg L -1 (4.38 g fed -1 ) on plant growth, yield, quality and chemical composition of eggplant (Solanum melongena, L.) under three levels of nitrogen, phosphorus and potassium fertilization (NPK50%, NPK75% and NPK100% from recommended doses). Field experiment was conducted at Experimental Farm of the Faculty of Agriculture, El-Mansoura University, Dakahlia Governorate, Egypt, in the season of 2016. The used experimental design was a split plot design with three replicates. As for, the treatment NPK fertilizers at rate of 75% from recommended dose with spraying plants by mixture of (Fe + Se) showed the highest significant values of the studied parameters (plant height, number of leaves plant -1 , leaves fresh and dry weight and total chlorophyll content), yield (fruits length, fruit diameter and yield, except number of fruits plant -1 was not significant) at any level of mineral fertilization as well as (N, P and K contents (%) and N, K uptake (g plant -1 ) in eggplant leaves, except P uptake which was non-significant comparing with the untreated plants and fruit quality (crude protein, total carbohydrates, dietary fiber and vitamin C except NO 3 which gave the opposite trend). The maximum values of NO 3 concentration in eggplant leaves were obtained by Fe foliar application with NPK-fertilization at rate of 100% RD. On the other hand, the treatment NPK100% x (Fe + Se) as mixture significantly increased the Fe and Se contents in the leaves of eggplant. Accordingly, the application of NPK at rate 75% RD with foliar application of iron and selenium in combination together at rate of 300 mg L -1 and 5 mg L -1 , respectively gave the highest significant values of all tested characters of eggplant (growth, yield and its quality) under study condition.

“…Thus, Se application has the potential to increase the nutritional value of the crop, the grain yield as well as enable plants to have abiotic tolerance. Se improves plant growth by accumulating starch in the chloroplast [ 14 ]. Besides, Se can also regulate the activities of several antioxidant enzymes and metabolites providing oxidative stress tolerance to plants [ 15 ].…”

Selenium Alleviates the Adverse Effect of Drought in Oilseed Crops Camelina (Camelina sativa L.) and Canola (Brassica napus L.)

Drought poses a serious threat to oilseed crops by lowering yield and crop failures under prolonged spells. A multi-year field investigation was conducted to enhance the drought tolerance in four genotypes of Camelina and canola by selenium (Se) application. The principal aim of the research was to optimize the crop yield by eliciting the physio-biochemical attributes by alleviating the adverse effects of drought stress. Both crops were cultivated under control (normal irrigation) and drought stress (skipping irrigation at stages i.e., vegetative and reproductive) conditions. Four different treatments of Se viz., seed priming with Se (75 μM), foliar application of Se (7.06 μM), foliar application of Se + Seed priming with Se (7.06 μM and 75 μM, respectively) and control (without Se), were implemented at the vegetative and reproductive stages of both crops. Sodium selenite (Na2SeO3), an inorganic compound was used as Se sources for both seed priming and foliar application. Data regarding physiochemical, antioxidants, and yield components were recorded as response variables at crop maturity. Results indicated that WP, OP, TP, proline, TSS, TFAA, TPr, TS, total chlorophyll contents, osmoprotectant (GB, anthocyanin, TPC, and flavonoids), antioxidants (APX, SOD, POD, and CAT), and yield components (number of branches per plant, thousand seed weight, seed, and biological yields were significantly improved by foliar Se + priming Se in both crops under drought stress. Moreover, this treatment was also helpful in boosting yield attributes under irrigated (non-stress) conditions. Camelina genotypes responded better to Se application as seed priming and foliar spray than canola for both years. It has concluded that Se application (either foliar or priming) can potentially alleviate adverse effects of drought stress in camelina and canola by eliciting various physio-biochemicals attributes under drought stress. Furthermore, Se application was also helpful for crop health under irrigated condition.
