“…ABA may also cause alteration of tissue sensitivity to ethylene . In ‘Granny Smith’ apples, Lara and Vendrell suggested that an increase in endogenous ABA concentration may precede the increase in ethylene responsiveness, although it was not clarified how this ABA increase promoted sensitivity to ethylene.…”

“…Hass avocado has been shown to advance climacteric ethylene biosynthesis and respiration peak, causing more rapid ripening . Application of exogenous ABA also accelerated induction of ethylene biosynthesis and advanced the onset of ripening in peaches, apple and mango, possibly by enhancing tissue sensitivity to ethylene or stimulating 1‐aminocyclopropane‐1‐carboxylic acid (ACC) synthase (ACS) accumulation and activity . As yet, limited research has been directed in recent years to determine the relationship between endogenous ABA and ripening in avocado.…”

“…Therefore, the sensitivity of 'Feizixiao' to Ethrel appears lower than that of 'Nuomici'. Lara and Vendrell (2000b) suggested that endogenous ABA concentration may be closely linked with sensitivity to ethylene. In our study, the endogenous ABA concentration in 'Nuomici' pericarp was found much higher than that in 'Feizixiao' (Fig.…”

Two litchi cultivars, a well-coloured 'Nuomici' and a poorly coloured 'Feizixiao', were used to investigate changes in endogenous abscisic acid (ABA) concentration and ethylene production during fruit maturation and to test the effects of exogenous growth regulators on litchi fruit maturation. Abscisic acid concentration in both the aril and pericarp increased with fruit maturation. Transfusion of ABA into the fruit 3 weeks before harvest accelerated, whereas transfusion of 6-benzyl aminopurine (6-BA) retarded sugar accumulation and pigmentation. The effect of 6-BA was assumed to link with the resultant decrease in ABA. In contrast, 1-aminocyclopropane-1-carboxylic acid (ACC) concentration and ACC oxidase (ACO) activities in the aril remained relatively constant during sugar accumulation. Transfusion of aminooxyacetic acid (AOA) significantly decreased ACC concentration but had no effect on sugar accumulation in the aril. These results suggested that endogenous ABA, but not ethylene, was critical for the sugar accumulation. However, the roles of ABA and ethylene in pericarp pigmentation were rather complicated. Application of exogenous ABA promoted anthocyanin synthesis significantly, but had very little effect on chlorophyll degradation. Ethylene production in litchi fruit decreased with development, but a transient increase of endogenous ethylene production was detected just around the colour break in 'Nuomici'. Enhanced ACO activity in the pericarp was detected during pigmentation. Ethrel at 400 mg l À1 showed no effect on pericarp coloration, but accelerated chlorophyll degradation and anthocyanin synthesis at a much higher concentration (800 mg l À1 ). Fruit dipped in ABA solution alone yielded no effect on chlorophyll degradation, but the combined use of ABA and Ethrel at 400 mg l À1 enhanced both chlorophyll degradation and anthocyanin synthesis. These results indicated the possible synergistic action of ethylene and ABA during litchi fruit colouration. ABA is suggested to play a more crucial role in anthocyanin synthesis, while ethylene is more important in chlorophyll degradation. ABA can increase the sensitivity of pericarp tissue to ethylene.

“…Ethylene evolution rates measured in 'Valencia' fruitlets after harvest are high even when compared to the rates measured during the climacteric phase of ripening climacteric fruits. We measured ethylene production rates up to 350 nl g À1 h À1 compared to 2,8,15,30,90,150,270 and 400 nl g À1 h À1 measured in climacteric fruits such as banana (McMurchie et al 1972), peach (Bonghi et al 1997), tomato (Klee 1993), apple (Lara and Vendrell 2000), plum (Abdi et al 1998), avocado (Feng et al 2000), passionfruit (Mita et al 1998) and Japanese apricot (Mita et al 1999), respectively.…”

Mature citrus fruits, which are classified as non-climacteric, evolve very low amounts of ethylene during ripening but respond to exogenous ethylene by ripening-related pigment changes and accelerated respiration. In the present study we show that young citrus fruitlets attached to the tree produce high levels of ethylene, which decrease dramatically towards maturation. Upon harvest, fruitlets exhibited a climacteric-like rise in ethylene production, preceded by induction of the genes for 1-aminocyclopropane-1-carboxylate (ACC) synthase 1 (CsACS1), ACC oxidase 1 (CsACO1) and the ethylene receptor CsERS1. This induction was advanced and augmented by exogenous ethylene or propylene, indicating an autocatalytic system II-like ethylene biosynthesis. In mature, detached fruit, very low rates of ethylene production were associated with constitutive expression of the ACC synthase 2 (CsACS2) and ethylene receptor CsETR1 genes (system I). CsACS1 gene expression was undetectable at this stage, even following ethylene or propylene treatment, and CsERS1 gene expression remained constant, indicating that no autocatalytic response had occurred. The transition from system II-like behavior of young fruitlets to system I behavior appears to be under developmental control.
