Re: Cross pollination

Mike,
   The effects of a cross pollination will be seen in the seeds the following
year. If you have poor pollination and a very low seed count, it could affect
fruit size and shape. Genetically speaking, the new material is in the seeds.
Male pollen grains have a tube nucleus and a reproductive nucleus. When the
pollen grain contacts the female it "germinates " and a pollen tube developes
and grows down to the ovules (immature seeds in the female). The genetic
information of the male is passed on by the reproductive nucleus of the male
pollen grain. If you have temperatures above 90, it is tough to get a
pollination to be successful. I don't know if the male pollen dies in the
heat or never becomes viable, the female may not be viable in elevated temps,
or maybe the pollen tube can't develop in the heat.....maybe all of the
above. If you artificially cool the female during one of these hot spells,
you can get them to set but it is not easy.
