Changes in levels of growth regulating substances during fruit development and maturation and the effects of abscisic acid application on ripening of apricot fruits were investigated. The results showed that the levels of growth promoting substances were high, but started to decrease rapidly just before the end of stage Ⅱ and continued throughout stage Ⅲ. The promoting substances almost disappeared in fully ripe fruits. The ABA-like inhibiting substances first appeared during the end of stage Ⅱ, increased significantly in stage Ⅲ, and reached a maximum level in fully ripe fruits. Exogenous ABA application enhanced fruit respiration rate and accelerated the ripening process when applied to preclimacteric fruits but inhibited these processes when applied to post-climacteric fruits. The above results suggested that the ABA may play an important role in apricot fruit ripening. The interrelationship of ABA, ethylene, and fruit ripening was discussed. 相似文献

Experiments were carried out to evaluate the effect of glucose on ripening and ethylene biosynthesis in tomato fruit (Lycopersicon esculentum Mill.). Fruit at the light-red stage were vacuum infiltrated with glucose solutions post-harvest and changes in 1-aminocyclopropane-1-carboxylic acid (ACC) synthase, ACC, ACC oxidase, and ethylene production monitored over time. ACC oxidase activity was also measured in pericarp discs from the same fruits that were treated either with glucose, fructose, mannose, or galactose. While control fruit displayed a typical peak of ethylene production, fruit treated with glucose did not. Glucose appeared to exert its effect on ethylene biosynthesis by suppressing ACC oxidase activity. Fructose, mannose, and galactose did not inhibit ACC oxidase activity in tomato pericarp discs. Glucose treatment inhibited ripening-associated colour development in whole fruit. The extent of inhibition of colour development was dependent upon the concentration of glucose. These results indicate that glucose may play an important role in ethylene-associated regulation of fruit ripening. 相似文献
