Evolutionary Modifications of Tristylous Breeding Systems, and stigmas occurring at different levels. These pollinations usually fail to produce seed, although in some modified tristylous breeding systems illegitimate crosses may be compatible, and result in seed production.mutineer 发表于 2025-3-25 23:32:06

Historical Perspectives on Heterostyly,in . by Clusius (van Dijk 1943). Few, if any, attempts were made to interpret the adaptive significance of this floral heteromorphism until Charles Darwin and Friedrich Hildebrand studied the phenomenon just after the middle of the 19th century. In 1862 Darwin published his first paper on dimorphicgenuine 发表于 2025-3-26 04:26:14

The Development of Heterostyly,ncipal feature that distinguishes the floral morphs is that they differ in stigma and anther heights. The sex organs are reciprocally positioned with anthers in flowers of one morph at the same level as stigmas in flowers of the other morph(s). This structural difference is usually accompanied by ainfatuation 发表于 2025-3-26 13:41:03

The Evolution of Heterostyly,represented female and male sexes respectively, but found that they were both functionally hermaphroditic. He demonstrated the infertility of self-pollinations and crosses between plants of the same form, and concluded that the two forms, although hermaphrodites, are “related to each other like male
