EFFECT OF ABA ON RESPIRATION OF BANANA FRUITS AND ITS RELATION TO ETHYLENE

Jiang Yueming Chen Fang Zhang Donglin Li Yuebiao Liu Shuxian( South China Institute of Botany, Academia Sinica, Guangzhou 510650 )  
Banana fruits ( Musa acuminta "Dwarf cavendish" ) were harvested mature and determined in terms of respiratory rate, ethylene production rate and ABA content, ABA appeared first and accumulated in the fruits, and only when ABA reached a certain threshold level, was the obvious ethylene evolution triggered, Ethylene evolution peak preceded respiration peak, Treatment with exogenous ABA promoted ethylene evolution and respiration of banana fruits, and such promotion effects on. the preclimacteric fruits were positively correlated with ABA concentrations within the range of 10-5 -10-8 mol/L, In the presence of Ag+, stimulation of respiration ( 60.3%- 94.7% ) and ethylene ( 55.2% - 83.2% ) by ABA were inhibited, Results showed that the effect of ABA on promotion of respiration could mainiy be due to the ethylene evolution.
