Re: Apple-Crop: Apple Maturity Testing in Michigan

2007-09-27 Thread amity 

Hello Listers:

Has this situation happened with both irrigated and non-irrigated  
apples, and are other tree fruits responding similarly in North  
America?  I understand, from a traveler, the grape and olive crops are  
very light and of poor quality in Italy this year due to the heat.

being as good an indicator of maturity as we would like. McIntosh are  
almost 5's on the SI scale, whereas stressed Macs are more like 6's. I  
ran the Blanpied-Silsby model a while back and predicted we would be  
at SI of 5-6 by the 20th of September (and the end of picking for CA  
storage) and for trees in good condition we are right on track for  
that. I find the model somewhat useful, although realistically it  
rarely differs by more than a few days from year-to-year.


Otherwise, the MA apple crop looks very nice right now although hail  
has been troublesome in a few MA orchards and probably too many New  
England orchards. We are coming off what has been a real good stone  
fruit year -- global warming anyone? (Ask me again after the upcoming  
winter!)


Your (and Bill's!) apple maturity reports are real nice. Mine are a  
little more shotgun, but if anyone is interested, they are all here:

Jon: I noticed your Honeycrisp are not as firm as the two McIntoshs and they
have less starch. I also noticed the same with our Honey crisp.  I usually
pick our apples at about 16 lbs firmness, mid range starch index 4-5 (on a 1
to 9 scale), and about 12 to 14% brix. I start picking if the firmness is
below 15lb regardless of the starch and sugar values because fruits don't
get firmer in storage.  I wait for higher brix if the firmness is above 16
lbs and the starch index is in mid range (4 to 5), but I pick them if they
have low starch (6 or higher) even if they are very firm.  I don't recommend
storing fruits for long if they have low starch, regardless of their
firmness and brix.  Our Red Delicious maturity is different from previous
years. They are soft and have low brix but they still have plenty of starch.
We ended up picking them because, as I mentioned earlier, fruits don't get
firmer is storage.  Mosbah Kushad, University of Illinois
