Spore Morphology and Gametophyte Development of Davallia denticulataÂ and Davallia trichomanoidesĭavallia denticulata and D. trichomanoides are two attractive and decorative fern species for ornamental. Spore morphology has an important role in fern taxonomy, while media composition has important role in the growth and development of their gametophytes. Such information on the two fern species was lacking. Therefore, this study aimed to reveal the information of the spore morphology and gametophyte developmental stages of D. The spores were collected from Bogor, West Java. The spores were sown in three sterile media.

Spore morphology and gametophyte development were observed under a stereoscopic microscope. denticulata showed the best gametophyte development, and formed mature gametophytes on the media of vermiculite, sphagnum moss, and perlite, while D.īoth gametophyte species reached their mature stage at 25 weeks after planting on the different media compositions. trichomanoides grew best into maturity stage on the media containing vermiculite, and sphagnum moss. Thus, the presence of sphagnum moss in the media is an important material for the growth and development of Davallia gametophyte. Keywords: Davallia, development, gametophyte, growth, mediaĭavallia denticulata dan D. trichomanoides merupakan dua spesies tumbuhan paku yang menarik dan indah untuk tanaman hias. Morfologi spora memiliki arti penting dalam taksonomi tumbuhan paku, sedangkan komposisi media berperan penting untuk pertumbuhan dan perkembangan gametofitnya.
