Table 3. Effect of high humus seedling media and beneficail microorganisms on vitamin C content of Chinese kale.
Antioxidant activity at the seedling stage (20 DIA) was obtained in SSM with actinomycetes +15% lenonardite (Treatment 3 ) (1.9285 mmol trox/g sample), followed by SSM with Beijerinckia+ 10% lenonarddite (Treatment 2) (0.9978 mmol Trox/g sample) and the control (0.9509 mmol with actinomycetes + 15% leonardite (Treatment 3) was significantly (p,0.01) higher than that of other treaments AT harvest (40DAI), the values of antioxidant activity did not duffer significantly between mistreatment at this stage, the maximum antioxidant activity was recorded with SSM with actinomyyycetes +15% leonardite (Treatment 3) (4.733 mmol trox/g sample), followed by SSM with Beijerinckia + 10% lenonardite (Treament 2) (4.352 mmol trolox/g sample) and the control (4.337 mmol trox/g sample). Our results indicated that antioxidant activity (DPPH assay) of Chinese lalllle obtained by SSM with actinomycetes + 15% lenoardite (Treatment 3) was highly significant (p
