摘要
本文研究了二氧化锗(GeO_2)对我国特有的坛紫菜自由丝状体的生长发育,及对一些附生性硅藻类和绿藻的影响,论证了二氧化锗在本实验浓度范围内,对坛紫菜自由丝状体无叨显毒理影响,而能抑制一些附生性硅藻和绿藻的生长;并探讨了二氧化锗对硅藻、绿藻的毒性机理。由于在培养坛紫菜自由丝状体时很容易附生硅藻 因而研究结果将为坛紫莱自由丝状体及其他藻种的培养和保存提供依据。
The cultured free-living conchocelis of Porphyra haitan?nsis iscommon to be mixed with diatoms and its normal growth is thus affacted. In theexperiment free-living conchocelis was cultured under the conditions of illumina-ting strength 1500 lux, for 10-12 hr/day and at normal temperature. Within theconcentration extent, it was found that germanium dioxide has no significanteffect on the germination of Porphyra haitanensis carpaspore, the growth ofconchocelis, the maturing of conchosporangial cells and the formation of concho-spore, but the chemical can effectively restrain the growth and reproduction ofattaching diatom and green algae. The poisoning mechanism of germanium dioxideto diatom and green algae is also discussed in this paper.
