Interactive effects of rice residue and water stress on growth and metabolism of wheat seedlings
Journal Title: Журнал ÑтреÑÑ-физиологии и биохимии - Year 2014, Vol 10, Issue 3
Abstract
In the present study effects of rice residue with and without water stress were studied on [i]Triticum aestivum[/i] L. cv. Shatabadi. The mixture of residue and garden soil in 1:1 ratio was considered as 50% (R[sub]1[/sub]) and only decomposed residue as 100% (R[sub]2[/sub]). Garden soil was taken as control. Twenty five seeds were sown in each experimental trays filled with soil mixture according to the treatments. Trays were arranged in two groups. After 15 days one set was subjected to water stress (WS) by withholding water supply for 3 days. Morphological and biochemical parameters of 18 days old seedlings were recorded. Seedling height decreased in all treatments. A gradual decrease in relative water content, pigment and protein contents of wheat seedlings were observed. Sugar and proline contents increased in treatments. An increase in malondialdehyde (MDA) content and antioxidative enzyme activities was recorded. Elevation in catalase activity was observed in all treatments except in plants with water deficit. Ascorbate peroxidase (APX) and guaiacol peroxidase (GPX) activities increased when residue mixed with soil but decreased in seedlings under the combined influence of the residue and water stress. Higher amount of MDA and lower activities of APX and GPX reflected the oxidative damage in seedlings under combined treatments. Rice residue inhibited growth of wheat seedlings. Water stress intensified the effects of residue.
