An introduction to Bryophyta: diversity, development and ...
In an extension of this work it was found that sporophytes of P. pyriforme and
hybrid sporophytes of F. hygrometrica x P. pyriforme form a callus tissue which
differentiates into apogamous sporophytes. A follow up (Bauer, 1963) revealed
that ...
apogamous sporophytes x in addition to protonema (Plate 5.4A.B; Kumra &
Chopra. 1980). Apogamous sporophytes also differentiate from the callus
obtained from protonema of F. hygrometrica on media containing higher
concentrations of ...

Sucrose also promotes apogamy in obligate apogamous forms like Cyrotomium
falcatum (Whittier, 1964b), and Cheilanthes tomentosa and C. farinosa (Whittier,
1965). A comparison made of gametophyte development between normal sexual
...

Green Plants: Their Origin and Diversity
Dryopteris affinis subsp. affinis (D. borreri) provides an example of a regular
apogamous cycle (Fig. 7.45A). In this and similar species the final mitosis of the
sporogenous cells is incomplete. Following division of the chromosomes the
nucleus ...

Apogamous populations, in which sporophytes are produced by gametophytes
without fertilization, were characterized by fixed heterozygosity and it appeared
likely that each such population had an independent origin. Work with Pellaea ...

1995; Banks 1999; Chatterjee and Roux 2000). Two obligately apogamous
laboratory strains of Ceratopteris have been described, both of which produce
nonfunctional sperma- tozoids. One strain resulted from the aneuploid
gametophyte of a ...

Developmental Biology of Fern Gametophytes
According to Whittier (1966b), diploid gametophytes of Pteridium aquilinum
produced from haploid ones by self-fertilization and apospory, generate more
apogamous sporophytes than their haploid counterparts. These limited data
suggest ...

Sporangia short-stalked, containing 32 spores, not intermixed with farina-
producing glands. n = 2n = 87, 116, apogamous. Sporulating summer-fall. Rocky
slopes and ledges, on a variety of substrates, including limestone and granite; ...

It is believed that apogamous ferns are mostly triploids (Lovis, 1977: Walker.
1979; Masuyama, 1984; Wagner and Wanger, 1980) and this is true in the case
of Cyrtomium also, but the hybrid C. caryotideum x C. falcatum which is a
pentaploid, ...
