Sugar Accumulation and its Regulation by Jasmonic Acid in Brassica napus L. under Salt Stress
Journal Title: Журнал ÑтреÑÑ-физиологии и биохимии - Year 2013, Vol 9, Issue 4
Abstract
The effects of Jasmonic acid (JA) on sugar accumulation and protein content in 12-days old [i]Brassica[/i] [i]napus[/i] L. seedlings were studied. The seeds pre-treated with different concentrations of jasmonic acid were germinated in Petriplates supplied with various concentrations of salt stress (NaCl). The contents of total chlorophyll, total sugars, reducing sugars, non-reducing sugars, total carbohydrates and total protein content of 12-days old seedlings were analysed. It was observed that JA reduced the toxicity of salt stress on seedling growth by influencing the chlorophyll content and protein content. Pre-treatment of jasmonic acid was found to be significantly effective in increasing the contents of sugars.

THE INFLUENCE OF HIGH Cd CONCENTRATIONS ON WINTER WHEAT (Triticum aestivum L.) AND CANOLA (Brassica napus L.) ETIOLATED SHOOTS
The influence of high CdCl2 concentrations on winter wheat (Triticum aestivum L.) and canola (Brassica napus L.) etiolated shoots was studied. It is shown that if in canola high Cd concentrations caused full inhibition o...
Physiological Response of the Green Algae Ulva lactuca (Chlorophyta) to Heavy Metals Stress
To monitor physiological changes induced by heavy metals contamination on the marine algae [i]Ulva lactuca[/i] (Chlorophyta), laboratory experiments were performed. Physiological effects of four heavy metals (Cu, Pb, Zn...

Хвойные экстракты, такие как Новосил и Лариксин в небольших дозах (0.3 мл/л) повышают стрессоустойчивость растений картофеля на примере изменения активности пероксидазы и в чистом виде подавляют рост возбудителя кольцево...
Активность, изоферментный спектр пероксидаз и дегидрины некоторых видов растений, произрастающих на берегах озера Байкал, при абиотическом стрессе
Термостабильность и оптимум рН слабосвязанной с клеточной стенкой и растворимой пероксидазы изменяется в зависимости от природных условий и сезонов вегетации. Активность пероксидазы тоже варьирует во времени. После пика...
