title: Sporophytic recognition of pollen S alleles in the gametophytic self-incompatibility system of Nemesia strumosa benth.
abstract: Several seedlings of Nemesia strumosa with various levels of pseudo-self-compatibility (PSC) often produced more seed after self pollination than when pollinated using pollen from incompatible plants bearing the same S alleles. Sporophytic recognition of self pollen apparently increases PSC levels above those attributable to modifying genes which interfere with normal stylar activity.
