إنجليزي. The research was conducted in 1998 and 1999 in a natural reserve located in North-Western Sardinia (Italy). Two typical species of Mediterranean maquis were studied, Pistacia lentiscus L. and Cistus monspeliensis L.. From March to November, the wound ethylene produced by the leaves of both species was measured by gas chromatography. During the trial, plant phenology and environmental conditions were monitored. From May to July, a period characterised by severe drought and soil moisture values constantly lower than the wilting point, ethylene production increased in both years for Cistus monspeliensis and in 1998 for Pistacia lentiscus. The amount of ethylene produced dropped sharply as soon as rainfall occurred. Significant relationships between ethylene production and Canopy Drought Stress Index were found

إيطالي. Lo studio è stato condotto durante il 1998 e il 1999 e ha riguardato due specie tipiche della macchia mediterranea, Pistacia lentiscus L. (lentisco) e Cistus monspeliensis L. (cisto). Periodicamente, da marzo a novembre, è stata misurata la concentrazione di etilene da ferita prodotto dalle foglie delle due specie per mezzo di un gascromatografo. Durante la prova sono state osservate le principali fasi fenologiche delle due specie e sono stati registrati i principali parametri meteorologici. Durante il periodo caratterizzato da condizioni di aridità molto elevate, è stato osservato un aumento significativo della produzione di etilene endogeno per il lentisco nel 1998 e in entrambi gli anni per il cisto. La quantità di etilene prodotto diminuiva nettamente non appena si verificava un evento piovoso. Correlazioni significative sono state osservate fra la quantità di etilene prodotto dalle due specie e l´indice di stress da aridità della vegetazione
