Influences of clonality on plant sexual reproduction PNAS

Heterostyly is a unique form of polymorphism and herkogamy in flowers. In a heterostylous species, two or three morphological types of flowers, termed "morphs", exist in the population. On each individual plant, all flowers share the same morph. The flower morphs differ in the lengths of the pistil and stamens, and these traits are not continuous. The morph phenotype is genetically linked to WebDetermining the functional breeding system of C. willmottianum can improve our understanding of the reproductive ecology of heterostylous plants. We investigated the floral traits and pollen and stigma characteristics in a natural population, and artificial pollination was carried out in an artificial population. how to say josiah in spanish
