[MassChestnutOrchards] temperature and catkin vs. female flower development

[Yvonne Federowicz]

I looked at the Chinese tree near my workplace yesterday.  The male catkins
are fully bushed out.  However the bisexual catkins are very short, with
many female flowers invisible from the ground.  (This is a tree that
produces many burrs.)

Last year, which stayed cool and rainy throughout flower development, I was
watching male catkins and planning to bag when they were half bushy.
However at that point, the females were quite large.

So I'm wondering if male catkins are a bit more temperature-sensitive than
female flowers, which might be more time-dependent.

(This would mean in very warm years, bagging when male catkins were further
along than in very cold years.)

Any thoughts?
