Primary Study Of The Cell Development Of Enteromorpha Prolifera (Ulvales, Chlorophyta)

In the present work, by cultivation of chopped tissues, the pathways and tendencyof the development of the cells within the chopped tissues of E. prolifera was studiedby observation and the mechanisms of the development were primarily discussed.Totally five different final pathways of the development of the cells within thesegments were found: a. develop into sporangium, b. develop into rhizoid, c. divideinto cluster of cells and become new young plants lately, d. become more polar anddevelop into young plants with rhizoid directly, e. become stable and remainundeveloped. The reproductive and regeneration diversity was studied systematicallyby observation and statistics during which seven reproductive and regeneration wayswere found. They are four reproductive ways employed by the alga including:anisogamy, reproduction from spores, single gametes, breakage of filaceousmicrophyte, and three regeneration ways: regeneration from segments, basal cells andcallus-like tissues. Through observation the phenomenon of conjunction of more thantwo gametes and the conjunction of two zygotes were also found and the earlydevelopment of the alga was observed. In this work, the reasons for the omnipresenceand rapidly proliferation and disperse of the alga in the wild were primarily analyzedand discussed which should not only prompt other researchers to figure out ways tocontrol the excessively proliferation of the alga, but also lay out foundations for thefurther massive culturing of the potential aquatic crop.
