Sep 1, 2016 · Unlike seed plants, ferns use their foliar surfaces for reproduction and carbon fixation. Across species, ferns exhibit a gradient of fertile–sterile dimorphy: from the production of highly reduced fertile fronds (holodimorphic) to no reduction (monomorphic) in laminar area between fronds.

Hemidimorphic ferns have the same frond that is separated into sterile and fertile portions and usually fertile fronds are significantly reduced laminar area (Watkins et al. 2016), as reported on...
In monomorphic ferns, the fertile and sterile leaves look morphologically the same, and both are able to photosynthesize. In hemidimorphic ferns, just a portion of the fertile leaf is different from the sterile leaves. In dimorphic (holomorphic) ferns, the two types of leaves are morphologically distinct. [9]
May 10, 2016 · Holodimorphic species produced fewer fertile fronds, which had significantly higher respiratory rates than in sterile fronds on the same plant or in any frond produced on monomorphic species; hemidimorphic species were frequently intermediate.

sterile fronds in ferns has been separated into three categories: (1) monomorphic, where fertile and sterile fronds are produced with similar degrees of laminar area, (2) hemidimorphic, where dimorphy

Mar 25, 2018 · The short LLS (4.1 and 7.7 months for fertile and sterile leaves, respectively) of Acrostichum danaeifolium, a mangrove hemidimorphic fern, may be attributed to the function of eliminating the accumulated salt (Sharpe 2010; Mehltreter and Sharpe 2013).
