Other claims from this paper (7)
- Observation Reactive oxygen species (superoxide anion and hydrogen peroxide) were generated in apple wounds immediately after wounding.
- Association Cryptococcus laurentii LS-28 colonised apple wounds faster and more greatly than Rhodotorula glutinis LS-11.
- Observation The number of LS-11 cells dropped 1 and 2 h after application to apple wounds and then increased only later.
- Intervention effect Combined application of biocontrol yeasts and ROS-deactivating enzymes prevented the decrease in LS-11 cell number in apple wounds.
- Association Polar lipids of LS-11 contained more unsaturated alpha-linolenic acid than LS-28, in which it was absent.
- Mechanism Resistance to oxidative stress could be a key mechanism of biocontrol yeast antagonism against postharvest wound pathogens in apple.
- Association In vitro, LS-28 was more resistant to ROS-generated oxidative stress.
