“…This may be due either to the absence of 12CO.0 evolution during illumination or to an efficient photosynthetic mechanism that is able to reabsorb tlhe CO., evolved within the leaf before it can escape to the outside. It has 'been observed previously (4,14,36,38) that an increase in the 0., con,tent of the gas stream suppresses photo.synthesis in many plants including corn. However, in corn, increasing 0., coIncentration had no effect on the CO., conmpensation point (15).…”

Abstract. The rate of CO,, evolution in light by green leaves was determined by 2 methods in a closed system of gas analysis and by measuring the amount of CO, evolved in-to a CO., free air stream in an open system. All methods gave similar results under comparable oonditions.A light stimulated CO., evolution from green leaves was found in all the plant species studied except corn where there was no apparent CO., evolution in the light.The magnitude of CO., evolution in light was markedly dependent on air flow rate and light intensity. At high light intensity and high flow rate, the rate of CO., evolution from green leaves was 1.4 to 1.7 times greater than that in darkness.In the pas.

Abstract. The Materials and MethodsChloroplasts were isolated from spinach obtained from local farnms or from markets. In the case of the former, leaves were picked immediately prior to their use in experiments. The leaves were immersed in wvater mlaintained at 200 and exposed to light (about 1000 ft-c) for 1 hr before use. This treatment was found to remove the "lag" period of CO., fixatioii. Two methods were used for the isolation of chloroplasts: A) about 20 g of deribbed leaves were subjected to a slight-lv modified version of the l)rocedure of Jensen and Bassham (18) or B) a similar quantity of leaves was treated according to the protocol of Gibbs and Calo (15). Ascorbate was eliminated from all solutions unless specified.The study was initiated using chloroplasts prepared in 0.35 M NaCl (15)
