Friends
There's been a lot of discussion about the viability of pollen after the
flower has been picked. I would like to see if anyone can answer this
question.
Does each grain of pollen from the same plant carry all the same genetic
codes or does each grain differ in the genetic codes it possesses?
Looking forward to some answers. Thanks

Jake,
Pollen grains have two parts...a tube nucleus and a reproductive nucleus.
One pollen grain could potentially be different than the one next to it. What
happens is the pollen grain germinates much like a seed does, and a pollen
tube grows down the inside of the female flower. Inside the baby female are
hundreds of ovules (immature seeds). The reproductive nucleus carrying the
genetic information from the male mates with the ovule and a seed starts to
develop. If you have 5 different strains of male pollen on a female, you could
have 5 different types of seeds in the new female. The results of a
pollination will not be seen in this years fruit. The resulting seeds when
planted next year will show the genetics of the cross.
