ABSTRACT
<p><b>OBJECTIVE</b>To study the relationship between Cibotium barometz and its companion species, Arachniodes falcate and Alpinia japonica, we used aqueous leachates of the two companions to deal with C. barometz spores.</p><p><b>METHOD</b>Spores of C. barometz were translated on MS culture which contained different concentration of aqueous extracts of the two companions, the germination and gametophyte development were observed and recorded.</p><p><b>RESULT</b>All extracts inhibited and delayed the C. barometz spores germination and rhizoid elongation was inhibited. It also had obvious inhibition to the prothallus formation and sexual differentiation. And the higher concentration, the more obvious inhibition of aqueous extracts of the two companion species.</p><p><b>CONCLUSION</b>The two companion species have allelopathic effects on the spore germination and gametophyte development of C. barometz. And it may have an influence on sporogon ontogenesis and the population expansion.</p>
