In conclusion, a detailed study of the ability of SC and SB to
induce resistance in oranges has been carried out.
The accumulation of phytoalexins and carbohydrates which are metabolites able
to control, directly or indirectly, pathogen infection, reinforces the
idea that PAL is involved in the mode of action of tested salts.
This response seems to sum up to citrus natural reaction to wounding,
enhancing its protective effect and contributing to a successful
defence against pathogens.
This study suggests that induced resistance
should be considered as an important aspect of the multiple
mechanisms of sodium salts for controlling postharvest decay of
citrus fruit.
