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 a

The expressed activity in pollen and stigma was determined for both S alleles of sixteen S-alíele heterozygous genotypes and for one of the two S alleles of two additional heterozygotes. Activities were measured using pollen tube penetration and seed set data from reciprocal crosses between each S-a
To estimate the numbers of sporophytic S-alleles in two adjacent populations of wild radish, we performed 701 reciprocal crosses among 50 individuals. Each cross was replicated five times in each direction. Sixteen plants were fully intercompatible, indicating the presence of at least 32 S-alleles i
