Additionally, the differential expression of proteins in response to co-cultivating Pista-9 and <em>F. oxysporum</em> in a low-carbon medium to promote fungal competition was evaluated. A liquid culture was prepared by adding 100μL of 10⁷ conidia/mL. As a test, Pista-9 was grown in the presence of the <em>F</em>. <em>oxysporum</em> live and heat-inactivated. The cultures were incubated at 28 °C for 7 days at 180 rpm. Then the solutions were filtered, and ammonium sulfate 0–85 % saturation was added. After the precipitation process, the protein extract was analyzed by one-dimensional electrophoresis and LC-MS/MS. The effect of protein extracts (300 μg/mL) on the growth of <em>F. oxysporum</em> was evaluated <em>in vitro</em>. <em>In vitro</em> antagonism tests demonstrated that Pista-9 is an effective biocontrol agent. Electrophoresis revealed that extracts presented majority bands ranging from 10 to 75 kDa and proteins such as glutaminase, metalloproteinase, chitinase, and peptide hydrolase were identified. The extract from Pista-9 was able to inhibit 71 % of <em>F</em>. <em>oxysporum</em> growth. Furthermore, the growth-promoting potential of the extract was evaluated through its application on tomato leaves. The results showed that the extract promoted growth and increased biomass.

Furthermore, the application of nanoparticle treatments—particularly SiO₂NPs—markedly increased both shoot and seed yields, with improvements of 85.3 % and 85.2 % respectively when applied alone. These enhancements were further amplified by the addition of Nano-NPK, yielding increases of 108.5 % for shoots and 91.2 % for seeds.

Accelerated aging significantly (p &lt; 0.05) reduced seed viability, GP, GRI, and CVG while increasing electrolyte leakage and water activity.

Germination declined significantly under prolonged aging, with ‘L2’ and ‘B2’ exhibiting over 50 % reductions in GP. The findings demonstrate that accelerated aging impairs seed quality through electrolyte leakage and moisture uptake demonstrated by water activity, with landrace-dependent sensitivity.
