An enzyme similar to the 3 -nucleotidase of mung bean has been isolated from germinating wheat seedlings and purified 800-fold (90). The preparation possessed DNase, RNase, and 3 -nucleotidase activities. These three activities were similar in pH optima, requirements for Zn2+ and sulfhydryl compounds, stability to storage, temperature inactivation...

In recent years the use of ion-exchange membranes for the selective extraction of heavy metals from soil suspensions and solutions have been developed, for example, for Cd, Cr, Ni and Pb (Liang and Schoenau, 1996). Extracts of Cd, Cu and Pb by this method were shown to be better correlated with wheat seedling uptake than chemical extraction with 0.1 moll-1 HC1, 0.01 moll-1 CaCl2 or 0.005moll-1 DTPA (Lee and Zhang, 1994). 

The above analytical considerations have been combined here to present a GC-MS/MS study carried out on the exudates of 17-day old wheat seedlings from 58 worldwide accessions of varied allelopathic activity, as ascertained in a previous screening.14 The target allelopathic agents chosen are the seven previously mentioned phenolic acids and DIMBOA.
