( Alshammary et al., 2004 ). Salinity stress may cause changes in hormone metabolism in plants, including the promotion of ethylene production ( Morgan and Drew, 1997 ). Increases in the production of an ethylene precursor, ACC, have been widely reported to be

, cell growth stopped and dormancy was restored ( Petel et al., 1993 ). 2,4-dichlorophenylacetic acid has been shown to break dormancy in cultured H. tuberosus tuber cells ( Bennici et al., 1982 ). In potato tubers, ethylene and gibberellic acid have

Ethylene is important in plant growth, including germination through seedling, flowering, and fruit development to senescence ( Abeles, 1973 ). Ethylene production is enhanced by stimuli such as infection, mechanical stress, pollination, ripening

‘Bartlett’ pear is a climacteric fruit that is harvested at 80 to 89 N when the fruit is still green and firm but physiologically mature. After harvest, pears are conditioned with ethylene and marketed immediately or stored at low temperatures

Most European pears ( Pyrus communis L.) require a period of chilling exposure after harvest to produce autocatalytic ethylene, ripen properly, and synchronize the ripening ( Sugar and Basile, 2013 , 2014 ; Villalobos-Acuña and Mitcham, 2008

Exopolygalacturonase (exo-PG) (EC was investigated for ability to induce ethylene production in green cherry tomatoes (Lycopersicon esculentum Mill.). The fruit were vacuum-infiltrated with various levels of exo-PG from green tomato fruit, squash flower, or oak pollen and compared to boiled enzyme or salt controls for ethylene production. In all cases, fruit treated with active enzymes produced significantly higher levels of ethylene than did control fruit. The ethylene response was evident 2 hours after treatment and was transient in nature, returning to basal levels by 22 hours. The amount of ethylene produced did not appear to be influenced by the source of exo-PG.
