“…This trend was reflected on the average values of fresh weight and oxalate contents in spinach plant. These results are in accordance with the findings of Turakainen et al (2008), Hawrylak-Nowak (2013), Yao et al (2009), Moussa et al (2010) and Saffaryazdi et al (2012). Table 3.…”

FIELD experiment was carried out at the Experimental Farm of the Faculty of Agric., El-Mansoura Univ. during season 2015, arranged in split block design with 3 replicates to evaluate the effect of 3 rates of NPK treatments (50, 100 and 150 % from recommended dose) as main plots and 4 levels of sodium selenite in a foliar way (0, 10, 20 and 30 mg kg-1) as sub plots. Results indicated that NPK fertilization up to 100 % under study significantly increased the average values of chlorophyll, fresh and dry weight, and total content of N, P and K as well as soluble and insoluble oxalate concentrations in spinach leaves as compared to the untreated plants. More addition of sodium selenite foliar application of sodium selenite at the lowest rates of 10 and 20 mg L-1 significantly increased the aforementioned traits while at the highest rate (30 mg L-1) significantly reduced the average values of all the previously mentioned traits. Also, the results indicated that, the mean values of total phenolic compounds, Se accumulation in leaves as well as the activity of nitrate reductase enzyme were significantly increased with the level of sodium selenite increasing. Such effect was realized under all the forms of NPKfertilizers. An adverse effect happened for the values of nitrate and nitrite accumulation in spinach leaves. It decreased sharply and significantly with increasing selenite level under all the investigated treatments. Obtained results proved that the foliar application of sodium selenite at the lowest levels (10 and 20 mg L-1) in combination with soil application of combined with NPK fertilization up to 100% is considered to be the most suitable treatment for all previous traits.

“…However, effect of Se on phytohormones balance and/or polyamine content could not be excluded. Selenium treated potato plants had higher putrescine content (Turakainen et al, 2008). Polyamines have been implicated in various plant growth and developmental processes including stimulation of cell division, embryogenesis, senescence, floral development, and fruit ripening (Kakkar and Sawhney 2002).…”

Selenium (Se) is a beneficial element for higher plants and its positive effect on plants growth and performance has been reported. Effect of Se under non-stress conditions especially during reproductive phase has not been attracted enough attention. In this work effect of Se supplementation at 0, 10 and 20 μg Se plant -1 was studied in canola (Brassica napus'RGS') plants during vegetative and reproductive phase of growth under greenhouse conditions. Selenium addition resulted in a significant enhancement of dry matter production of vegetative parts as well as pod and seed dry weight. In addition, Se supplementation caused a considerable acceleration of reproductive events. In vegetative plants, higher photosynthesis rate, carbohydrates and protein content in the leaves was observed in Se treated plants compared with control. Our results suggested beneficial effect of Se on canola seed yield that may also contribute in improving nutritional value of canola for livestock and human.Key words: flowering, pod dry weight, reproductive phase, seed yield IZVLEČEK DODATEK SELENA POSPEŠUJE RAST IN REPRODUKCIJO PRI RASTLINAH KANOLE (Brassica napus L.)Selen (Se) je za višje rastline koristen element, znani so njegovi ugodni vplivi na rast rastlin. Pri rastlinah, ki rastejo v nestresnih razmerah, zlasti v reproduktivni fazi razvoja, učinki Se še niso bili ustrezno raziskani. V tem delu so avtorji raziskovali dodatek Se (0, 10 in 20 μg Se na rastlino) pri kanoli (Brassica napus L., cv. RGS) tekom vegetativne in reproduktivne faze. Dodatek Se je povzročil značilno povečanje sušine vegetativnih delov, luskov in semen. Dodatek Se je vplival tudi na pospešitev poteka reprodukcije. Pri rastlinah je bila ugotovljena tudi povečana fotosinteza, večja vsebnost ogljikovih hidratov in beljakovin v listih tretiranih rastlin v primerjavi s kontrolo. Rezultati kažejo na ugoden vpliv Se na pridelek kanole, kar lahko vpliva tudi na izboljšano hranilno vrednost te poljščine za živali in ljudi.
