Abstract
Brown heart is a tissue disorder found in Conference
pears during CA storage.
Differences in susceptibility for brown heart have
been found between countries, orchards, harvest dates and storage conditions.
One hypothesis is that brown heart is caused by
increased internal CO2. This research focussed on
establishing internal CO2 levels by measuring gas exchange rates and
the resistance to gas diffusion.Different harvest
dates, post-harvest treatments and storage periods have been compared with
regard to respiration, fermentation and diffusion resistance and internal CO2
concentration was estimated.
Comparing less sensitive and sensitive pears
showed the same maximum respiration rate and lower maximum fermentation rate
but also more brown heart for the sensitive pears after storage.
This indicates that internal CO2
is not the primary cause of brown heart.
