Metabolic studies of explosives. 1--EI and CI mass spectrometry of metabolites of 2,4,6-trinitrotoluene

A series of metabolites of trinitrotoluene (TNT) have been synthesized and analysed by electron impact (EI) and chemical ionization (CI) mass spectrometry. Identification characteristics of these metabolites by their mass spectra have been determined. Differentiation of isomers is made possible by EI ions which are characteristic of the position of the methyl with regard to the nitro groups.     

Modification of Sex Expression in Muskmelon by Treatment with the Growth Retardant B-995

Treatment of an andromonoecious cultivar of muskmelon with N, N-dimethylaminosuccinamic acid (B-995) induced a shift towards femaleness. This tendency was expressed by a reduction in the number of staminate (male) flowers, an increase in the number of hermaphrodite flowers and a shift in flowering pattern resulting in the formation of hemaphrodite flowers at lower nodes. The treatment also caused a change in the habitus of the plants from the regular pole type to a dwarf type, which was manifested by a marked reduction in node length and the suppression of tendril formation. The mode of action of B-995 on sex expression is discussed.
