After 20 years of hybridizing, I still believe that the optimum time for
making a cross, requires two things. The presence of the liquid on the
stigma, and the condtion of the pollen on the anther, fluffy. Ben Z
disagrees. He claims to have sucessfull crosses made way out side these
perameters. I have to think , though, that the more "grains" of "good"
pollen that "stick" to the stigma, the better chances for a productive
cross. The resulting differences, could be in seedling numbers, as well
as quality. I will do more observation and recording of results this
year.
