A pollination question
In order to get my cherry trees to have cherries, I had to plant two
dissimilar varieties. This is what I don't get. Variety A needs a var B to pollinate it. Var A produces cherries. I plant the seed. Presumably this seed has DNA from both A & B. When this seedling matures it will require a pollinator in order to make cherries. How would I know if it needed an A or a B type? In species where varieties are self infertile, how is it that the varieties can stay in any way distinct? I'm 43 and I've wondered about this for most of my life, so thanks in advance for your replies. --Bryan |

I can't speak for cherries, but I suspect that in general you wouldn't know. Depending on the mechanism of self-incompatibility, the seedling could be compatible with both A and B, one of A and B, or neither A and B - and another seedling from the same cross may be different. The web has over 500 pages which contain the terms "Prunus" and "self- incompatibility"; a significant proportion are on self-incompatibility in Prunus. URL:http://www.google.com/search?num=100&hl=en&lr=&ie=ISO- 8859-1&as_qdr=all&q=Prunus+self-incompatibility. Hopefully one of these pages will explain how it works in Prunus. In species where varieties are self infertile, how is it that the varieties can stay in any way distinct? They are propagated vegetatively.

A pollination question
I am not a professional botanist, but I'll give this a stab. Maybe some one
else has a more detailed answer. There are many different inherited mechanisms in plants to prevent self-pollination. I don't know the precise ones in cherries. Presumably this seed has DNA from both A & B. The question is which self-incompatibility gene it inherited, if any. When this seedling matures it will require a pollinator in order to make cherries. The word you want is pollenizer. The pollinator is the bee. You don't know offhand which pollenizer the offspring will require. A professional pomologist might. At any rate, as I told the fellow looking for apple seedlings, it is not practical for the amateur to try growing fruit trees from seed, as they take many years to produce fruit, and very rarely produce a superior variety. In species where varieties are self infertile, how is it that the varieties can stay in any way distinct? They are only propagated vegetatively, by cuttings, grafting, or meristemming.
