The water-soluble carbohydrates contributing to the response of wheat seedlings to cadmium stress in nutrient solution were studied with or without Ti(IV)-ascorbate supply. The total water-soluble carbohydrate, glucose, fructose, sucrose, glucan and fructan contents, and the cadmium and titanium contents were measured in wheat seedlings exposed to 10-4 M Cd or 10-5M Cd with either Ti(IV)-ascorbate or Na-ascorbate in the medium. Glucose, fructose and fructan showed the greatest response to Cd, ascorbate and titanium treatments. The sugar content in plants exposed to Cd increased with the metal concentration. Titanium tended to decrease the cadmium-induced sugar accumulation. Ti(IV)-ascorbate and Na-ascorbate were also applied without Cd to study the effect of these chemicals. In general, Na-ascorbate induced a higher accumulation of sugar components than Ti(IV)-ascorbate. Titanium addition in Cd-containing solution caused a significant decrease in the cadmium accumulation in the leaves. An increase in titanium content was observed only in the roots, higher values being measured in plants grown in solution containing 10-4 M Cd.

Heavy metal toxicity has become a universal threat to all life forms, including plants. The main purpose of this study was to identify the gene expression profiling of MAPK, Thioredoxin, and MnSOD genes in wheat seedlings as affected by cadmium treatment. For this experiment, the quantitative Real-Time PCR on RNA isolated from shoots of wheat exposed to CdCl2 at a concentration of 100 mg/L was used. Results showed that in wheat seedling that exposed to cadmium stress for six days of beginning constant cadmium stress, Thioredoxin gene expression showed a large rise compared with the control sample, MnSOD gene expression increased compared with non-treated wheat seedling at the same times, but unlike the Thioredoxin and MnSOD genes, MAPK gene expression has no significant changes. Of course, it is possible that other times of beginning treatments (instead of six days) cause a change in this gene expression.

Resistance Function

Using spring wheat as tested materials, by pot experiments and three fertilization modes (seed soaking mode, irrigated fertilization mode and mixed using mode), the effects of sodium humate on the wheat seedlings growth and mineral elements (Cu, Zn, Fe, Mn) absorption were studied. The results indicated that, all three modes showed obviously resistance performance to Cd stress, promoted the wheat seedlings growth and the dry matter accumulation, and the third mode had the best effects. In the background soil, sodium humate treatments could obviously inhibit the Cd elements absorption; promote the mineral elements absorption and accumulation. Along with the Cd stress degree aggravateing, the inhibition effects reduced. At the same time, different fertilization modes had different effects on mineral elements absorption and accumulation. The research also puts forward that humic acid fertilizer is an ecological fertilizer and soil conditioner with alleviate heavy metals pollution and enhance plant stress resistance function.
