Title: The Pollen Receptivity Period and Its Relation to Fruit Setting in the Stone Fruits
Author: T. K. Toyama
There is little information in the
literature pertaining to the length of
time after anthesis that flowers of the
stone fruits remain receptive to pollen.
The available information indicates that receptivity decreases rapidly after anthesis.
Bradbury (1), in
Wisconsin, noted that the stigmas
turned brown and began to wither 3
to 4 days after anthesis in Prunus
cerasus. Eaton (23, working in Ohio
and Ontario, found that the proportion of functional embryo sacs decreased rapidly after anthesis in
Windsor sweet cherry (Prunus avium).
He obtained a much higher rate of
fertilization from pollinations 1 day
after anthesis than from pollinations 2
days after anthesis.
