[NAFEX] Elephant Heart plum question

Elephant Heart suffers from pitch pockets.  It's an inherited 
physiological disorder.  The flesh grows at uneven rates in certain 
conditions, creating cracks that fill up with callus and pitch.  Heart 
shaped varieties are especially prone to it.  Redheart plum has  
similar  flavor and  quality to Elephant Heart, but because it's round 
it almost never gets pitch pockets.

Elephant Heart plums are a huge hit with my family.  My wife comes from 
Ethiopia so she was raised on a lot of low acid tropical fruit- think 
mangoes. I like E H plums a lot too, but I'm having a bit of a problem 
with my new tree.  My last tree was in a fairly shadey spot, but this 
didn't stop the E H from getting extremely sweet, however it suffered 
fatal cambium injury one year as sometimes happens here with many 
red-fleshed types besides Methely.  I had already planted another on 
the south side of my house next to an aluminum Airstream trailer. 
I have trained the tree to grow over the trailer to make use of the sun 
there and to provide the tree with extra reflected light.  The tree has 
grown very well and started producing fruit its fourth year and has a 
decent crop again this year.  The question is why do the earlier plums 
develope hard spots around the seed that makes them less pleasant to 
eat?  It's a little like stink-bug injury on a pear but the affected 
flesh is actually light brown.  Some of the plums are deformed with 
large sunken spots at the location of this hardened tissue.  I never 
experienced this with my previous tree or with Elephant Heart trees I 
grew many years ago in Ca.  I'm in Z 6, southeastern NY.  I wonder if I 
have a defective tree somehow or more probably if the extra light is 
the issue. _______________________________________________
