| 摘 要： | 香蕉果实采后过程中,脱落酸(ABA)首先生成并积累。当ABA达到—定水平后才明显出现乙烯生成。外源ABA处理果实促进呼吸作用和乙烯发生。在10~(-5)-10~(-2)mol/L浓度内,ABA对跃变前果实的呼吸和乙烯的促进作用与其处理的浓度呈正相关。外加Ag~+处理可抑制ABA对呼吸(60.3％-94.7％)和乙烯(55.2％-89.2％)的促进作用。结果表明,ABA对果实呼吸的促进作用主要是通过刺激乙烯的产生进行的。

| Abstract: | 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. |
