On mode of rythmological evolution of ferns
Possible ways of rhythmological evolution of ferns are outlined on the basis of comparison of basal evergreen phenorhythmotype with derived rhythms occurring in temperate ferns. Terminal stages of intra-bud morphogenesis and extra-bud morphogenesis of fronds of short-rhizomatous chamephytes and hemi...

| Summary: | Possible ways of rhythmological evolution of ferns are outlined on the basis of comparison of basal evergreen phenorhythmotype with derived rhythms occurring in temperate ferns. Terminal stages of intra-bud morphogenesis and extra-bud morphogenesis of fronds of short-rhizomatous chamephytes and hemicryptophytes (Athyrium, Polypodium sp. div., Lepisorus, Pyrrosia, Nephrolepis, Asplenium bulbiferum, A. viviparum, A. trichomanes), long-rhizomatous erosulate hemicryptophytes (Gymnocarpium) and geophytes (Pteridium) are analyzed. Modes of biomorphological evolution resulting in change of phenorhythmotypes are detected. |
