It has also been shown that dark respiration does not depend upon oxygen concentration but proceeds at about the same rate in low oxygen concentrations (2 precent) as in the concentration found in ambient air (20 percent).On the other hand,photorespiration rates increase as oxygen concentrations increase from 2 to 20 precent.The very small magnitude of photorespiration for an illuminated leaf,while difficult to measure,has been determined.

大意是:无光照时,植物的呼吸与氧气的浓度无关,在低浓度的环境下(2%)或者大气环境下(20%)其呼吸效率是一样的.但在光照下,呼吸效率与氧气浓度成正比.尽管很难测量,但光照下植物呼吸效率的小幅变动还是被测出来了.
