Foliar Spraying of Mannose Alleviates Cadmium Stress by Changing the Subcellular Distribution and Chemical Forms of Cadmium in Wheat Root

Cadmium (Cd)-contaminated soil has been receiving increasing attention worldwide due to the great harm it causes via food-chain enrichment through crops such as wheat. However, there is little research regarding effects of mannose (MAN) on plants in response Cd stress. Hence, hydroponic and potted experiments were conducted investigate mitigation MAN wheat under stress possible mechanism. Compared with treatment alone, foliar spraying 160 ?M significantly reduced accumulation shoots increased retention roots. The content hemicellulose was by treatment, proportion retained cell wall roots increased. Furthermore, water-extracted ethanol-extracted roots, which are easily transported shoots. In using Cd-contaminated soil, grain 26.3%, compared control. These findings indicate that resulted less being from changing chemical forms promoted growth concentration grain.
