Stress ethylene production in seed and fruit of Sechium edule Swartz

Summary

The intact fruit and isolated seed and fruit tissues of Sechium edule Swartz were analysed for ethylene production, ACC content and activity of the enzymes involved in ethylene biosynthesis (ACS and ACO) in consequence to wounding. Stress ethylene production follows different patterns according to which the different tissues of the fruit and seed are concerned. On the whole the data obtained indicate that the seed teguments are the only tissue that is characterised by an increase in ACS activity and in ethylene production in relation to stress.
