Poor stand establishment of vegetables is attributable to low seed vigor and high susceptibility to stressful biotic and abiotic soil environments. The objective of this paper was to describe lhe effect of matriconditioning integrated with fungicide, GA and biological seed treatments on performance of vegetable crops, and their effectiveness on physiological and biochemical changes. Matriconditioning ameliorated lhe performance of eggplant and tomato seeds in 1999 field plantings in Brazil. Reduction in time to 50% (T 50) emergence in conditioned seeds ranged from 4 days in eggplant to 2 days in tomato. Further improvement in emergence rate occurred by inclusion of gibberellin (GA4+ 7) during conditioning. Eggplant and tomato seed germination is influenced by endosperm cell layer digestion by GA-induced enzymes, which reduce mechanical restraints to lhe embryo. Pre-sowing seed conditioning in lhe presence of Bacillus subtilis proved effective in increasing sweet corn shoot dry weight in lhe field, but lhe addition of GA during matriconditioning in sweet corn had a negative effect. Fungicide added to brittle genotype sweet corn seeds with or without conditioning improved lhe final percentage emergence by 140 and 125% when compared to non-conditioned seeds. Osmoconditioning with PEG reduced lhe emergence rate and shoot weight production of both hybrids. Electrolyte leakage was greater in brittle sweet corn seeds carrying lhe bt2 gene compared to lhe sugary type, and in both cases, matriconditioning reduced lhe leakage. Matriconditioning with or without biological seed treatmet may be a feasible strategy in improving stand and yield of sweet corn of lower seed quality under tropical conditions.
