Abstract
|
|
|
|
Effects of GA and IAA on the respiratory and photosynthetic activity of each growth stage during the synchronous culture of Chlorella ellipsodiea, were investigated. 1) GA (2 × 10^-8M) affected most insignificantly on the respiratory activity of the stages Dn, Da, L₁, L₂, L₃-cells but only at L₄-cells treated with IAA(10^-3M) were promoted and L₃, L₄-cells were suppressed. With the treatment of GA-IAA the effects on respiration of each stage cells were antagonistic. 2) Photosynthetic activity treated with GA during the each stage of Chlorella cells was promoted and IAA treated-cell were suppressed. The effect of GA-IAA upon the process of life cycle was also antagonistic. 3) It was revealed that respiratory and photosynthetic activity of Chlorella cells by the treatment of GA(2 × 10^-8M) and IAA(10^-3M) had antagonistic effects.
