中文摘要:
      室内晾干不同时间(2—12小时)四种海藻失水达90%。晾干2—12小时对紫菜的毛光合有促进作用。晾干7小时内对石莼的毛光合有促进作用,8小时出现抑制作用;晾干5小时内对礁膜的毛光合有促进作用,6小时出现抑制作用;不同时间晾干的孔石莼电光合均低于对照。晾干2—12小时,四种海藻的净光合速率均有下降,而呼吸作用均受到了不同程度的促进。
英文摘要:
      Desiccated in room for different times (2--12 hrs), the dehy-dration rates of all four algae reach to ninety percent. Desiccation for 2--12 hrsstimulates the gross photosynthesis rate on Porphyre yezoensis. Desiecated in 7 hrs.the gross photosynthesis rate of Ulva lactusa gets a stimulation, but longcr than 8 hrsit shows inhibition. The same result on Monostroma nitidum: 5 hrs stimulates, longcrthan 6 hrs inhibits. Of all the different desiceation times, Ulva pertusa shows thegroso photosynthesis rate lower than its control. After desiccated for 2--12 hrs, the net photosythesis rate of the four algae all decrease, while in contrast to their respira-tion rates, all increase to some degree.
