Studies on the behavior of incompatible pollen in Brassica. V.

Brassica oleracea L. var. caulo-rapa DC., var. acephala DC., and var. gemmifera ZENKER

Abstract

In these cole crops, the incompatible pollen and tube behavior was found to be similar to that of the common cabbage respectively. The self-incompatibility is due to decreased germination of incompatible pollen and to no penetration of tubes into the stigma.
