No references found | Cyatheaceae, Gametophyte, Morphology, Development ********** Gametophyte morphology of ferns including types of spore germination, early development, mature form, trichomes, and gametangia, has been considered to be the significant, defining characteristic of fern taxa (Atkinson and Stokey, 1964; Nayar and Kaur, 1971; Atkinson, 1973). Gametangia Development in the Moss Physcomitrella patens (Rumiko Kofuji, Takeshi Yoshimura, Haruko Inoue, Keiko Sakakibara, Yuji Hiwatashi, Tetsuya Kurata, Tsuyoshi Aoyama, Kunihiko Ueda, and Mitsuyasu Hasebe). In order to observe the sequence of formation of gametangia on each individual gametophyte, 50 young gametophytes from the multispore agar cultures were transplanted at the 15-30 cell stage and separately arranged in a regular pattern in two Petri dishes as follows: six rows of gametophytes per dish, the first row with two gametophytes, the following four rows with five gametophytes per row, and the last row with three. |
