“…Generally, SA and Tre treatment appeared to be the most effective treatment in counteracting the negative effects of water stress on AAO, POD, PAL and PPO activities. These results are similar to those obtained by Kumar et al [69] who stated increased of enzyme activity with foliar application of SA. Moreover, treatment of drought stressed plants with exogenous SA was found to be effective in modulating both enzymatic and nonenzymatic components of antioxidant defense system [17].…”

In this study, the protective role of salicylic acid (SA) and trehalose (Tre) in relation to lipid peroxidation, membrane leakage, membrane stability index, antioxidant defense system as well as non-enzymatic antioxidants were investigated in drought stressed wheat Gemmieza-7 (drought sensitive cultivar) and Sahel-1 (drought tolerant cultivar) plants. Water stress reduced bio-membranes stability through inducing its lipid peroxidation resulting in an increment in membrane leakage with marked decrease in membrane stability index of flag leaf of both wheat cultivars during grain-filling. Moreover, it was obvious that drought significantly increased the activity of ascorbic acid oxidase (AAO), peroxidase (POD) and phenylalanine ammonia lyase (PAL) activities and induced non-significant reduction in polyphenol oxidase (PPO) activity in flag leaves of both wheat cultivars during grain-filling in comparing with well watered plants. Among cultivars, tolerant one showed higher enzymes activity than the sensitive one. Application of SA and/or Tre markedly increased AAO, POD and PAL activities and non-significant decrease in PPO activity in flag leaf of water stressed wheat plants. Generally, SA and Tre treatment appeared to be the most effective treatment in counteracting the negative effects of water stress and Sahel-1 appeared to induce better results than Gemmieza-7 and proved to be more tolerant.Drought stress caused significant increase in the amount of total phenols and flavonoids in flag leaf of both cultivars during grain-filling where the sensitive plants accumulated more total phenols and flavonoids contents than the tolerant one. Furthermore, water stress increased the non-photosynthetic pigment content of the two wheat cultivars particularly drought sensitive one during grain filling. These results suggest that the exogenous application of SA and/or Tre assisted the plants to become more tolerant to drought stress-induced oxidative damage by upregulating the membrane characteristics and enhancing their antioxidant defense system as well as non-enzymatic antioxidants.

“…Others workers while working with spraying of higher concentration of bio-regulators in legumes also recorded decrease in yield of crop due to impeding effect on photosynthesis (Kumar et al, 2013;Kumar et al, 2014 andKumar& Sarlach, 2015) Chemical analysis of seeds (seed quality) Minerals and crude protein percentages Percentages of nitrogen: Results shown in Table 5 revealed that plants treated with concentrations of 15 and 20 ppm selenium had no significant differences in nitrogen percentage of faba bean seeds. On the other hand, plants treated with other concentration gave a significant increase in percentage of nitrogen in both seasons.…”

“…By contrast, the higher concentration of 20 ppm selenium enhanced significant decrease in number of pods plant -1 of faba bean in two seasons ,being 27.8 and 29.5 % less than the control in 2014/2015 and 2015/2016 seasons, respectively. The information about exogenous application of selenium on the number of pods /plant of faba bean or other related species is meager but it is well documented that bio-regulators spray at higher concentrations in legume crops inhibit photosynthesis and affects yield of plants (Kumar et al, 2013;Kumar et al, 2014 andSarlach, 2015).…”

T HIS WORK was conducted during the two successive winter seasons of 2014/ 2015 and 2015 / 2016 at the Agricultural Experiments and Researches Station (Ghazala Farm), Faculty of Agriculture , Zagazig University , Sharkia Governorate, Egypt, to study the effect of foliar spray with selenium at concentrations of 0, 2.5 , 5 , 10 , 15 and 20 ppm on growth, chemical composition , yield as well as anatomy of stem and leaves of faba bean cv. Giza 716. The experimental results showed that foliar application with 20 ppm selenium showed no effect on vegetative growth , yield components ,seed quality, photosynthetic pigments (chl a , chl b, total chl and carotenoids) concentration, carbohydrates fractions , minerals and crude protein percentage. Foliar application with 10 ppm selenium significant improvement effects on vegetative growth , yield, seed quality, photosynthetic pigments, carbohydrates fractions, minerals and crude protein percentage of faba bean cv. Giza 716. Foliar application with 10 ppm selenium induced favorable enhancement in anatomical feature of stem and leaves. Exogenous application of selenium also induced prominent increase in diameter of stem, thickness of cortex, number of cortical layers, average length and width of vascular bundle, average vessels number per vascular bundle and average diameter of vessel . Likewise, increased thickness of both midvein and lamina, increased thickness of mesophyll size of midvein bundle, length and width of midvein bundle and vessel diameter were increased as a result of spraying selenium.

This study was designed to evaluate the role of growth regulator trinexapac and fungicides on growth, yield, and quality of winter rapeseed (Brassica napus L.). The experiment was conducted simultaneously at different locations in Germany using two cultivars of rapeseed. Five different fungicides belonging to the triazole and strobilurin groups, as well as a growth regulator trinexapac, were tested in this study. A total of seven combinations of these fungicides and growth regulator trinexapac were applied at two growth stages of rapeseed. These two stages include green floral bud stage (BBCH 53) and the course of pod development stage (BBCH 65). The results showed that plant height and leaf area index were affected significantly by the application of fungicides. Treatments exhibited induced photosynthetic ability and delayed senescence, which improved the morphological characters and yield components of rape plants at both locations. Triazole, in combination with strobilurin, led to the highest seed yield over other treatments at both experimental locations. Significant effects of fungicides on unsaturated fatty acids of rapeseed oil were observed. Fungicides did not cause any apparent variation in the values of free fatty acids and peroxide of rapeseed oil. Results of our study demonstrate that judicious use of fungicides in rapeseed may help to achieve sustainable farming to obtain higher yield
