| Abstract/Contents: | "Apomicts provide the opportunity to investigate the variation in achene size and performance that is due to factors other than genetic differences between achenes . Achene characteristics of a single capitulum from each of 15 biotypes of apomictic Taraxacum were investigated. Within a capitulum, achene fresh weight ranged from 4路45 fold to 13路74-fold. Overall, 59路8% of achenes germinated. The probability of any one achene germinating was influenced both by its source and by its weight and ranged from 0路049 to 0路902 between capitula and from 0路028 to 0路873 between weight classes. An investigation of the relationship between achene parts in three biotypes identified a linear trend for embryos to acquire a greater proportion of total achene weight as achene weight increases. Although the heaviest achenes showed the best germination , it is predicted that, for a given investment of maternal resources, seedling number would be maximized by producing achenes of a single intermediate weight." |
