WebPollen structure. The present studies of anther types (based on their mode of dehiscence) accounted for 206 angiospermic species belonging to 140 genera of 45 families. Two main types of anther dehiscence were observed viz., longitudinal and poricidal. Among the subtypes of longitudinal dehiscence, latrorse type is most common found in 114 ... WebAug 5, 2024 · Anther and pollen traits: size, quantity and quality. To test for differences in anther size and trade-offs between anther size, pollen size and pollen quantity between pollinating and feeding anthers, we measured the size of anthers (N = 20 anthers; two per flower, one flower per individual) and pollen grains (N = 16; two per flower, one flower per …

WebFeb 1, 2024 · Poricidal dehiscence in nine of the species is accomplished by resorption and/or collapse tissues. Resorption tissue alone occurs in two species, both in one, and six species have only collapse tissue. Cells of both tissues are initially meristematic. Resorption tissue develops crystals and breaks down in the same way as granular pouches. Webspecies of Lycianthes typically have poricidal anther dehiscence. The entire genus was last monographed in 1919 by Bitter, who arranged the species into sections and series but provided no identifi- cation key (Bitter, 1919).
