呼吸作用反映果蔬的生理状态,呼吸强度是一种果蔬对周围环境生理反映的生理指标。一般在静态条件下测定果蔬的CO_2释放、O_2吸收还是方便的,但在高CO_2条件下测定果蔬的呼吸速率显得不可能。同时,果蔬本身生成的 CO_2、C_2H_4又会影响果蔬的呼吸,乙烯对果蔬的生理作用很大。因此,在连续气流条件下同时测定果蔬的 O_2吸收、CO_2与 C_2H_4释放,
Respiration reflects the physiological state of fruits and vegetables, respiration intensity is a physiological indicator of the physiological response of fruits and vegetables to the surrounding environment. Under normal conditions, the determination of CO_2 release of fruits and vegetables, O_2 absorption or convenient, but in the high CO_2 measured fruit and vegetable respiratory rate is impossible. At the same time, fruits and vegetables themselves generated CO_2, C_2H_4 will affect the respiration of fruits and vegetables, ethylene on the physiological role of fruits and vegetables great. Therefore, simultaneous determination of O_2 absorption in fruits and vegetables, release of CO_2 and C_2H_4,
