Ascorbic acid, thiamine or salicylic acid induced changes in some physiological parameters in wheat grown under copper stress

Abstract

The fresh and dry weight of roots and shoots of wheat seedlings showed a marked decrease as the concentration of copper (Cu) was increased. The contents of pectin, cellulose, soluble carbohydrates, and phospholipids in the roots and shoots of test plants were significantly lowered with the rise of Cu concentration. However, hemicellulose, lignin, total lipids, glycolipids, sterols and proline of roots and shoots were raised under Cu stress. Cu treatment also induced the stimulation of soluble, total and cell wall associated proteins, other free amino acids and total carbohydrates in shoots and a slight reduction in roots. The adverse effects of Cu toxicity treatments on root and shoot growth were partially alleviated by the treatment of test plants with ascorbic acid, thiamine (vitamin B<sub>1</sub>) and salicylic acid.

Ameliorative effect of Yeast Extract, IAA and Green-synthesized Nano Zinc Oxide on the Growth of Cu-stressed Vicia faba Seedlings

“…The Cu-induced inhibition in carbohydrate content could be attributed to a reduction in CO 2 fixation that showed a direct relation with the Cu inhibited biosynthesis of chlorophyll (Azmat & Khan, 2011). It may also bedue to the stimulation in the activity of dark respiration causing great depletion in carbohydrate content under Cu toxicity as stated by Al-Hakimi & Hamada (2011). Cu application caused a significant decrease in soluble protein level which is in accordance with the results of Qi et al (2006) and Yadav & Mohanpuria (2009).…”

Thiamine and Pyridoxine Alleviate Oxidative Damage by Copper Stress in Green Alga Chlorella vulgaris

“…Thiamine or pyridoxine treatments induced pronounced inhibition in the accumulation of proline and MDA content when compared to algae treated with only Cu +2 (Al-Hakimi & Hamada, 2011). This confirmed the alleviating capacity of these vitamins on the algal growth.…”

Control of cucumber (Cucumis sativus L.) tolerance to chilling stress—evaluating the role of ascorbic acid and glutathione

“…The oxidative and reductive status of AsA and GSH are closely related to the adaptation of plants to stressed environments, and the accomplishment of AsA function depends largely on the available GSH supply and the conditions of oxidation and reduction in cells (Anjum et al, 2010). Lowered extent of oxidative stress and enhanced stress resistance in plants has also been reported with exogenous application (seed treatment, soil influx or foliar spraying) of AsA (Dolatabadian et al, 2008;Dolatabadian and Saleh, 2009;Al-Hakimi and Hamada, 2011;Kumar et al, 2011b) or GSH (Cai et al, 2010;Teh et al, 2014).…”
