摘    要:为了研究红树植物的感化作用,于2000年8月至2000年9月14日用秋茄(Kandelia candel),木榄(Bruguiera gymnorrhiza)各器官浸出液对木槛胚轴进行室内栽培试验,结果发现,木榄(除枝条外)和秋茄浸出液可提高木榄胚轴发芽率,木榄根浸出液延迟发芽而秋茄浸出液则加快发芽,在各器官中根浸出液明显率为0,木榄+秋茄群落的化感物质总体上有利于木榄的天然更新。

关 键 词:木榄  秋茄  化感作用  萌根发芽  红树植物  红树林

Abstract:To research the allelopathy of mangrove, the aqueous extract from parts of Bruguiera gymnorrhiza and Kandelia candel were employed in the hypocotyls culture experiment of B. gymnorrhiza. The aqueous extract of these two plants except branch of B. gymnorrhiza could increased the hypocotyls germination rate. The germination speed was delayed by the root aqueous extract of B. gymnorrhiza but promoted by parts of Kandelia candel.The rooting rate was high to 100% and rooting speed was improved in the root aqueous extract of both plants. No rooting was found in the branch aqueous extract of K. candel. It suggests that the allelochemicals of B. gymnorrhiza+K.candel community is favored to the self regeneration of B.gymnorrhiza.
Keywords:Bruguiera gymnorrhiza  Kandelia candel  allelopathy  rooting and germination
