PACKINGHOUSE NEWSLETTER
STEM-END RIND BREAKDOWN
Stem-end rind breakdown (SERB) has recently been seen on 'Murcotts' and
'Valencias.' When the humidity is low, as has occurred lately, and there is any
delay in handling, this type of peel injury often develops. Affected fruit usually
looks normal enough at time of packing, but can develop stem-end rind breakdown
during transit or marketing. SERB symptoms vary, but they usually appear as a
collapse of the rind cells at the stem-end (button-end) of the fruit. A narrow
ring of cells around the button usually remain normal in appearance. This ring of
healthy tissue is useful for identification. The area of breakdown gradually
increases in size and becomes darker in color. SERB is more likely to appear on
small sized, thin-skinned fruit.
To avoid SERB, follow these suggestions:
1. Reduce the time between picking and waxing.
2. Keep fruit in the shade after picking.
3. Cover loads of fruit with a canvas, especially when long hauls are involved.
Do not use transparent plastic as it traps heat.
4. At the packinghouse, if fruit must be held for any length of time:
a. Place the fruit in a degreening room with high (90% +) humidity with
the fan operating for air movement. Do not use ethylene or heat.
b. These holding conditions will keep the fruit as firm as when it was
brought to the packinghouse.
c. Waxed fruit may develop SERB if held too long under drying conditions;
cool temperatures and high humidity are the best conditions.
All varieties of oranges and specialty fruit are subject to SERB to varying
degrees. Grapefruit do not develop this type of peel injury unless they are
subjected to extreme drying conditions.

KUMQUATS OR CALAMONDINS ANYONE?
We have had an inquiry from a German importer wanting to buy kumquats and
calamondins (presumably for preserves). If anyone wants to supply either or
both of these, please get in touch with us; and we will see what can be done to
work up a mini-sized export market.
