For once, I actually agree with you Jon. ;-)
I don’t have your skills and talent, so I know I should stick to the easy
topics like pathology that my simple mind can understand.
So from your friendly comment I conclude that all this was all quite
predictable? Good.
My only goal here was to confirm that this data made sense. If it does,
I’m happy.
I don’t intend to publish in Nature. I rely on you for that. ;-)
have a nice weekend!
PS = You should come up here and teach us. Your French level is not bad!

Bonjour Vincent! Désolé, mais peut-être que vous devriez vous en tenir à
l'entomologie et de la pathologie et de laisser la recherche horticole très
dur très important pour les vrais experts! :-)

Hello, sorry for the delay.
Yes, correct. Crop load influenced fruit weight notwithstanding ReTain.
Fruits left on tree at harvest were more numerous and larger when treated
with Retain. Fruits were up to 56g larger (148g vs 92g) depending on the
specifics of the ReTain application.
What I also found interesting was that the average fruit pressure of
retain treated fruit significantly dropped for fruit left on the trees. As
if the fruit stuck to the tree with Retain, and continued to grow but got
softer.
The Brix index was also influenced by the number of fruits on the tree:
lower Brix on trees with more fruit. Retain also increased sugar content.
Not much else to report.
I’m not usually into physiology. This was a “accidental” project for us!

As I understand your most recent explanation, both the untreated and the
ReTain-treated trees
produced greater fruit size at harvest if they were borne on trees most
heavily-set at start of
experiment. And that the ReTain treated trees showed a greater
size/initial number of fruit than did the
untreated. If the difference in fruit size for treated versus untreated
is small, I would not be much
bothered by it. Can you tell us how much different they were?

Hello!
Thank you all for your input!
I did not explain why I was looking at drop and fruit size: it was an
experiment on the use of ReTain.
In the end I’m not sure I can pinpoint the reason this increased fruit
size on trees with more apples (notwithstanding ReTain), but your input
underlined that a number of variables can be involved! I liked Duane’s idea.
If you’re curious, the report will read: ReTain Treatments significantly
increased harvested McIntosh yield as compared to the control (p0.0001).
Average fruit size at harvest was proportional to the total number
of fruits on the trees present at the start of the experiment (p=0.01) and
fruits treated with ReTain were larger than in the control (p=0.02).
The effect of ReTain on harvest was expected (drop prevention) but the
effect on fruit size was undetectable if the model was not adjusted to the
initial crop load (thus my question)
So the next question is now: why are ReTain treated fruits bigger than
untreated fruit at harvest?
bye for now,
Vincent
