This is a follow up to the discussion line, "Mulching fruit trees" to delay
flowering.
Several years ago James Claypool grafted maybe 50 side branches of his
pistillate trees with male scions to better pollinate his trees. Because I'm
breeding and desired to know which genotypes broke bud early and which ones late I
made several trips to his orchard during bud break.
I discovered that males with early bud break grafted to late bud break
genotypes still broke bud early while the rest of the tree was still dormant. And
likewise late bud break males were still dormant while the rest of the early
breaking tree grafted to had green shoots. The conclusion I derived at was, in
persimmon early and late bud break is controlled more by the tree genetics than
temperature.
For what it's worth.
