Other claims from this paper (15)
- Observation Bacillus atrophaeus YL84 in dual culture inhibited mycelial growth of V. dahliae with an inhibition rate of 84.11%.
- Observation The YL84 sterilized fermentation filtrate, undiluted or diluted to 10%, inhibited mycelial growth of V. dahliae by 72.16%.
- Observation Scanning electron microscopy showed increased branching, swelling and shortened internodes in the antagonized mycelia.
- Intervention effect The YL84 filtrate increased conductivity of the pathogen mycelia 8.94 times relative to the control at 250 μg/mL.
- Intervention effect The YL84 filtrate caused protein leakage that peaked at 9.47 times the control level at 250 μg/mL.
- Intervention effect YL84 sterilized fermentation filtrate significantly reduced polygalacturonase (PG) activity from 15.78 to 11.81 U/mL.
- Intervention effect YL84 sterilized fermentation filtrate significantly reduced cellulase (CL) activity from 10.11 to 6.96 U/mL.
- Intervention effect YL84 sterilized fermentation filtrate significantly reduced β-glucosidase (β-GC) activity from 5.01 to 1.44 U/mL.
- Intervention effect Indoor pot experiments showed that different concentrations of YL84 sterilized fermentation filtrate significantly suppressed the occurrence of cotton Verticillium wilt.
- Intervention effect The 250 μg/mL YL84 sterilized fermentation filtrate gave a control efficacy of 66.69% against cotton Verticillium wilt compared with the control group.
- Intervention effect The 250 μg/mL YL84 sterilized fermentation filtrate increased cotton plant height by 9.36–33.85% relative to the control group.
- Intervention effect The 250 μg/mL YL84 sterilized fermentation filtrate increased cotton root length by 17.33–29.49% relative to the control group.
- Intervention effect The 250 μg/mL YL84 sterilized fermentation filtrate increased cotton fresh weight by 16.79–28.24% relative to the control group.
- Intervention effect The 250 μg/mL YL84 sterilized fermentation filtrate increased cotton dry weight by 25–58.33% relative to the control group.
- Recommendation The YL84 sterilized fermentation filtrate is a promising candidate for development and use as a cotton biocontrol agent and plant growth promoter.
