The influence of Cadmium(Cd) on exudation of low molecular weight organic acids (LMWOAs) were investigated based on the hydroponic culture experiment. Tartaric, citric, malic, and acetic acids were chosen as representatives of LMWOAs commonly present in roots exudation. We investigated the Cadmium accumulation in Triticum aestivum L.. The results showed that under the different levels of Cd, the exudation of four organic acids by roots had the different change trend. The concentrations of four organic acids in roots exudation were in the same following sequence tartaric>citric>malic>acetic. And the content of Cd in plants increased with increasing Cd concentrations. We found that at first some LMWOAs increased at low Cd treatments, we guessed that it was a normal reaction to the Cd treatment.

Bat Guano

Pot experiment is carried out at the greenhouse belongs to the college of Education-university of Al-Anbar during Winter season 2013/2014 to investigate the effect of application of different levels of bat guano (0, 4 and 8gm) on some yield  traits for two bread wheat Triticum aestivum L. Cvs, one is local cv. (Aliz) another one is imported from Australia (Eratom). The experimental treatments are distributed according factorial experiment arrangement using completely randomized blocks with three replicates. Some traits are measured as spikes no per plant, spike length, spike weight, grains nos. per spike and grains weight per pot. Results reveal that bat guano application of 8gm is significantly superior in the average of. It thus could be concluded that the application of bat guano at 8gm alone is the better than 4gm in some traits. However, the genetic affinity of local cv is dominated with 4gm application and of imported cv is to 8gm application. Therefore, it could be recommended to test the application of bat guano on the two cultivars across field environment

Cd Accumulation

A hydroponic culture experiment was conducted to study the effect of temperature and nutrient level on Cd accumulation inTagetes erectaL.. In the first experiment, shoot Cd accumulation and transpiration rate at different temperature was determined. Cd accumulation was lower with higher transpiration rate at 35°C than that of 25°C or 15°C with lower transpiration rate. In the other experiment, cadmium accumulation of plants varies significantly under the condition of different nutrient supplication. Contents of Cd in roots were not high, but the contents of Cd in shoots were the highest when plants were cultivated in 0.05-fold Hoagland’s solution. Roots Cd accumulation decreased as the concentration of single nutrient element (N, P, S) decrease or absence, and shoots Cd accumulation decrease in the condition of sulfur deficiency and sulfur absence. It was shown that transpiration is not the primary factor affecting Cd accumulation inTagetes erectaL, but growth rate of plants has certain correlation with Cd accumulation; contents of Cd in roots are most affected by the supplication of nutrient elements, yet shoots accumulation is relatively lagging behind; different nutrient element has some different effect on Cd accumulation, and the effects of nitrogen and sulfur on the shoots Cd accumulation are the greatest.
