Abstract

Guye, M. G, Vigh, L. and Wilson, J. M. 1987. Chilling-induced ethylene production in relation to chill-sensitivity in Phaseolus spp.-J. exp. Bot. 38: 680-690.Ethylene production from the primary leaves of six bean (Phaseolus spp.) cultivars known to differ in chill-sensitivity, was monitored at 23 °C following chilling of whole plants at 5 °C for 24 h. The more chill-tolerant cultivars produced greater amounts of chilling-induced ethylene than the chill-sensitive cultivars. The onset of maximum ethylene production rates and the following decline in rates was more rapid in chill-tolerant cultivars. This pattern of ethylene production was also similar when chill-tolerance was chemically enhanced by choline treatment. The low levels of ethylene production in chill-sensitive genotypes was also reflected by their poor ability to convert the exogenously applied ethylene precursor, 1-aminocyclopropane-l-carboxylic acid (ACC), to ethylene.Moderate levels of leaf water deficit induced by chilling chill-tolerant cultivars and choline treated plants appeared to stimulate chilling-induced ethylene production. High levels of leaf wilt, shown by more chill-sensitive cultivars, reduced this stimulatory effect. Ethylene production was slightly greater when warming was carried out in the light rather than in the dark.
