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.
