Summary
Cotton field soils fromFusarium wilt-free zone (KPT) and a wilt-sick zone (PLD), and root exudates of diploid and amphidiploid strains of cotton grown in these two soils were analyzed for B-vitamins by microbiological assay technique employing X-ray mutants ofNeurospora crassa andN. sitophila.
PLD soil was found to contain choline, pyridoxine,p-aminobenzoic acid, traces of biotin, and inositol. KPT soil was found to contain pyridoxine, choline, thiamine,p-aminobenzoic acid, and traces of biotin and inositol.
Thiamine, biotin, pyridoxine, andp-aminobenzoic acid were found in higher amounts in the exudates of diploid cotton strains, especially K 2 and 6186.9 in KPT soil. In addition to the above, choline was also found in the exudates of diploid strains grown in PLD soil.
Amphidiploid strains showed comparatively lower amounts of these vitamins in the root exudates with a few exceptions.
In the inoculated series, inositol was absent in most cases and the contents of other vitamins were reduced to varying extents compared to the respective healthy controls.
