摘要
为了扩大红树林栽培,进行北移试种前在低温控制室的低温处理试验,探索不同的红树种类的抗寒特性。结果表明:在受害温度以上的低温处理时,红树植物幼苗叶片电解质渗出率与处理温度关系不大,但有滞后现象;在临近受害低温处理下,白骨壤出现严重受害温度为0°~-2℃,海莲略高于0℃,秋茄、桐花树、木榄、尖瓣海莲则低于-2℃。这些结果可以作为引种驯化工作的依据之一。
The characteristics of chilling-resistance of six mangrove plants hasbeen studied.By the treatment of serial low temperatures in artificial control room,the ratesof electrolyte efflux from the leaf tissues of mangrove seedlings were found not to be directlysignificant relative with treated temperatures above 0℃,But low temperature caused a lagchilling injury to seedlings.The fatal low temperature of Avicennia marina was 0℃~-2℃,Bruguiera sexangula was near above 0℃,B. Aymnorhiza,B. sexangula var rhyn-chopetala,Kandelia candel and Aegiceras corniculatum were all below-2℃.
