摘要

Abstract

This Mar. 1993 to Aug. 1994 study on suspended conchocelis ofPorphyra haitanensis showed that there were three patterns for development of vegetative filaments: filaments to filaments by “budding”; filaments to sporangial branchlets by “budding”

or cell swelling. There were also three patterms for sporangial branchlet development: vegetatively propagating

changing into conchospores

or dying. Each developmental stage had one or more different developmental directions between vegetative filaments and sporangial branchlets. Developments from conchosporangial branchlets to conchospores were sequential and irreversible. Although sporangial branchlets formed at 29°C could give rise to filaments

they could not propagate as healthily under the same conditions as those formed at 25°C did. Probably the crucial period of plant cell differentiation is in the late stage of sporangial branchlets. In line with the developmental directions of different stages

the authors regulated the development of conchocelis to get ideal different developmental stages materials to obtain very developmentally homogeneous stages

including filaments and sporangial branchlets.
