Re: [Aroid-l] Aroid breeding problems

From: "Culture Sheet" <team at culturesheet.org> on 2009.01.06 at 12:24:46(18875) Brian, just a thought, don't really think it applies to this genus but you might be interested: +More in some families/genera it's common that A x B doesn't work, while B x A does. There are a few reasons, like barriers on the stigma, but one of them which is often overlooked is the pollen-tube length. As the pollen grain germinates it sends a pollen tube to the embryonic cells. In some species this distance is too far for the pollen of the other species so the cross is impossible in one way. The Araceae is somewhat special in this case because of the extremely short distance, but I would try to reverse the cross to rule this out. regards, Fred _______________________________________________ Aroid-L mailing list Aroid-L@www.gizmoworks.com http://www.gizmoworks.com/mailman/listinfo/aroid-l
