Popis: | The genus Pandorea, family Bignoniaceae, occurs naturally in Australia. Pandorea pandorana and P. jasminoides were used in intraspecific diallel crosses in order to test for the presence of self-incompatibility and the effect of genotype. Both species were found to be highly self-incompatible. Only 2 out of 353 (0.6%) selfpollinations compared to 337 out of 485 (69.5%) of outcross-pollinations of P. pandorana set fruit. Similarly, for P. jasminoides, 4 out of 235 (1.7%) self-pollinations and 175 out of 296 (59.1%) of outcross pollinations set fruit. Both reciprocal and genotype effects were found in P. pandorana. Fruit-set differences occurred between two different genotypes of P. jasminoides, but reciprocal effects were not found. Data were analysed using generalized linear models with a logit-link function assuming a binomial error distribution. The relative merits of the various models are discussed. |
