“…However, it has been reported that high ODC activity is assollated with fruit growth and active cell divisions, as in tcmmato (Heimer, 1979), tobacco (Slocum and Galston, 1985), and avocado (Kushad et al, 1988). Similar patterns for ODC and ADC were found in pear by Biasi et al (1991), and values ranging between 2 and 8 were reported for ADC/ODC ratio in mandarin orange in early fruit growth (Nathan et al, 1984). Biasi et al (1991) and Teitel et al (1985) also associated low ADC and/or ODC activity with lack of cell division and with fruit growth due to cell enlargement.…”

Enzymatic activities involved in putrescine metabolism in ovaries of /%um sativum 1. during ovary senescence and fruit set were investigated. Accumulation of putrescine was observed during incubation of extracts from gibberellic acid-treated unpollinated ovaries (young developing fruits) but not in extracts from untreated ovaries (senescent ovaries). Extracts from pea ovaries showed arginine decarboxylase (ADC) activity, but ornithine decarboxylase and arginase activity were not detected. ADC activity decreased in presenescent ovaries and increased markedly after induction of fruit set with gibberellic acid. lncreases in ADC activity were also observed with application of other plant growth substances (benzyladenine and 2,4-dichlorophenoxyacetic acid), after pollination, and in the slender (Ia cry") pea mutant. By contrast, putrescine oxidase activity increased in presenescent ovaries but did not increase during early fruit development. All of these results suggest that ADC and putrescine oxidase are involved in the control of putrescine metabolism. Ovary senescence is characterized by the absence of putrescine biosynthesis enzymes and increased levels of putrescine oxidase and fruit development by an increase in ADC and a constant leve1 of putrescine oxidase.

“…Decrease in polyamines at the late stage of fruit development has been regarded as a signal for fruit ripening 13 . However, during fruit maturation and ripening an increase in polyamine titers was also detected in citrus 54 and tomato 72 .…”

Polyamines, including putrescine (Put), spermidine (Spd) and spermine (Spm), are polycationic compounds of low molecular weight that are widely distributed in living organisms. They are implicated in a variety of plant processes, such as floral and fruit development. In addition, correlation between polyamines and flower gender or fertility is reported in some plant species. Since polyamines, especially Spd and Spm share a common precursor, S-adenosylmethionine (SAM), with ethylene, they demonstrated competitive effects on functions in fruit development and ripening in many plants. Exogenous polyamines have been employed to regulate floral and fruit development and ripening in a lot of plants. Besides, polyamines have shown their potential for postharvest fruit management. Therefore, in this review, we focused on the involvement of polyamines in floral and fruit development along with perspectives of polyamine research.

“…In avocado (13,26), apple (6), pear (25), and tomato cv Rutgers (4) fruits, free polyamine levels decline during fruit development. An increase is observed in the fruits of mandarin (16), Shamouti orange (11), and tomato landrace Alcobaca containing the recessive allele alc (7) during fruit maturation and ripening. Infusing polyamines into pear fruits delayed fruit ripening (25).…”

Fruits of tomato, Lycopersicon esculentum Mill. cv Liberty, ripen slowly and have a prolonged keeping quality. Ethylene production and the levels of polyamines in pericarp of cv Liberty, Pik Red, and Rutgers were measured in relation to fruit development. Depending on the stage of fruit development, Liberty produced between 16 and 38% of the ethylene produced by Pik Red and Rutgers. The polyamines putrescine, spermidine, and spermine were present in all cultivars. Cadaverine was detected only in Rutgers. Levels of putrescine and spermidine declined between the immature and mature green stages of development and prior to the onset of climacteric ethylene production. In Pik Red and Rutgers, the decline persisted, whereas in Liberty, the putrescine level increased during ripening. Ripe pericarp of Liberty contained about three and six times more free (unconjugated) polyamines than Pik Red and Rutgers, respectively. No pronounced changes in spermidine or cadaverine occurred during ripening. The increase in the free polyamine level in ripe pericarp of Liberty may account for the reduction of climacteric ethylene production, and prolonged storage life.A regulatory role for polyamines in plants is suggested by their ubiquity, their abundance in actively growing tissues and their decline in senescing tissues, the regulation of their production by factors that affect plant growth and development, and their effects on plant growth and development when applied to plants (9,10,22). Little is known about the role of polyamines in fruit development. In avocado (13, 26), apple (6), pear (25), and tomato cv Rutgers (4) fruits, free polyamine levels decline during fruit development. An increase is observed in the fruits of mandarin (16), Shamouti orange (11), and tomato landrace Alcobaca containing the recessive allele alc (7) during fruit maturation and ripening. Infusing polyamines into pear fruits delayed fruit ripening (25). These findings suggest that free polyamines serve as endogenous antisenescence agents.Ethylene is a senescence-promoting hormone and accelerates fruit ripening (1, 27). Free polyamines inhibited ethylene production in a variety of tissues (2,5,8,24) opposite effects in relation to fruit ripening and senescence (3,5,9,22,26). Because of this, polyamine and ethylene physiologies may be linked during fruit development. This paper describes the changes in free polyamine levels and ethylene production during fruit development in pericarp from normal and slow ripening tomato cultivars. MATERIALS AND METHODS Plant MaterialFruits at various stages ofdevelopment were harvested from greenhouse-grown plants oftomato (Lycopersicon esculentum Mill.) cv Liberty, Pik Red, and Rutgers. Fruits were graded for maturity and ripening stages (12,17). The six fruit stages used were immature green, mature green, breaker, pink, light red, and red. Polyamine AnalysisPolyamine analyses were performed as described elsewhere (23). Because free, but not conjugated, polyamines have been implicated as endogenous antisenescenc...
