Another limitation to the studies in Table 1 is the small number of plant species tested. Primarily monocotyledonous plants have been studied, although McClure et al. (26) found ferulic acid inhibitory in soybean. The restriction of studies to monocots is probably because the mechanism of mineral absorption has been more fully elucidated with monocots. Harper and Balke (32) reported some minor differences in the inhibition of K+ absorption by salicylic acid among oats (Avena sativa L.), wheat (Triticum aestlvum L.), barley, and maize roots.

Paraquat adsorbed to soils is usually unavailable to crops. In the case of wheat (Triticum aestivum), effects from contaminated soils were negligible until soil residues surpassed 600 to 1000 kg/ha, causing growth reduction of 10%, or 1650 kg/ha, causing elevated residues in leaves but not in grain (Moyer and Lindwall 1985).

In addition to highly variable root to shoot ratios (0.01-1.22) the use of these values is complicated by (1) ratios that are hybrid, variety, and species-specific and (2) below-ground allocations that are impacted by stress (Herbert et al. 2001 Bradford et al. 2005 Amos and Walters 2006 Johnson et al. 2006). For example, Johnson et al. (2006) used root to shoot ratios of 0.82,0.55, and 0.62 for wheat (Triticum aestivum), com, and soybean (Glycine max), respectively whereas Amos and Walters (2006) reported that root to shoot ratios increased with N and P deficiencies and decreased with increasing water stress, population, shade, and soil compaction. 

Inhibitive effects are especially influenced by amount of cover crop biomass and soil management. Weed dry matter was reduced when rye residues were greater than 3.7 Mg ha-1 (Crutchfield et al. 1985), and when wheat residues were greater than Mg ha-1 (De Almeida 1985). Fisk et al. (2001) reported that burr medic (Medicago polymorpha L.) and barrel medic (M. truncatula Gaertn.) reduced by 70% weed dry weights while weed density was not affected if were no-till seeded as winter-killed cover crops into winter wheat (Triticum aestivum L.) stubble.

Starch is one of the most abimdant plant polysaccharides and is a major source of carbohydrates and energy in the human diet (Zobel and Stephen, 1995). Starch is the most widely used hydrocolloid in the food industry (Wanous, 2004), and is also a widely used industrial substrate polymer. Total annual world production of starch is approximately 60 million MT and it is predicted to increase by additional approximately 10 million MT by 2010 (FAO, 2006b LMC International, 2002 S. K. Patil and Associates, 2007). Com/maize Zea mays L.), cassava (also known as tapioca—Manihot escu-lenta Crantn.), sweet potato Ipomoea batatas L.), wheat Triticum aestivum L.), and potato Solanum tuberosum L.) are the major sources of starch, while rice Oryza sativa L.), barley Hordeum vulgare L.), sago Cycas spp.), arrowroot Tacca leontopetaloides (L.) Kimtze), buckwheat Fagopyrum esculentum Moench), etc. contribute in lesser amounts to total global production. 

Radionuelides can be also used to study the accumulation and degradation of organic pollutants. In our experiments we have followed the uptake and degradation of labelled TNT by wetland plants (Nepovim et al., 2005), and showed that about 63% of the localized in the roots of Ph. australis was bound (Fig. 6) and the remainder was acetone-extractable. An HPLC analysis of the acetone extract failed to detect any TNT, showing that all TNT had been chemically transformed. Thus TNT was not adsorbed on the root surface. In similar experiments performed in wheat (Triticum aestivum). Sens et al. (1999) found that 57% of the taken up was bound...
