Abstract
Pollen of pecan [Carya illinoinensis (Wangenh.) K. Koch] from four trees each of five protandrous and five protogynous genotypes was analyzed for germinability and fatty acid profile. Fatty acid profiles as a function of genotype were distinctive in all selections using analysis of variance, but only three of the genotypes had fatty acid profiles that were easily distinguishable from others by canonical discrirninant analysis. Specific fatty acid percentages influenced germination in some genotypes. Total saturated and unsaturated fatty acids influenced pollen germination to a greater degree than individual fatty acids. The effects of fatty acids on pollen germination of protandrous genotypes were opposite those on 'Stuart', the only protogynous genotype to be influenced by fatty acid percentages.
