Effects of water deficit on the leaf water relations of pot-grown olive cultivars

An experiment was conducted to investigate the water relations of potted young olive trees (Olea europaea L.) cultivar ‘Biancolilla’, ‘Giarraffa’ and ‘Nocellara del Belice’ during water stress and after relief from stress. The aim was to highlight the different responses of the three cultivars and obtain a decision-making aid for planning an efficient watering schedule for potted plants grown in nurseries. Leaf water potential (Ψ), relative water content (RWC) and conductance to water vapour (gL) were measured in three-year-old plants. All three olive cultivars were able to survive the severe stress imposed by withholding water for three weeks, but gas exchange was strongly impaired and rec…

Water relations in young manna ash trees grown under drought conditions

ECOFISIOLOGIA DELLE OLEACEAE: EFFETTI DELLO STRESS IDRICO SULLE PRINCIPALI CULTIVAR DI OLIVO DEL PANORAMA AGRICOLO SICILIANO

Le specie e le cultivar che crescono in ambiente mediterraneo rispondono in maniera diversa alle condizioni di aridita', con differenti adattamenti ecofisiologici. Sono state misurate le variazioni in alcuni parametri quali potenziale idrico fogliare, conduttanza stomatica, attività di superossido dismutasi e perossidasi, contenuto di mannitolo in differenti specie di frassino da manna e cultivar di olivo cresciute in regimi irrigui differenti.

La fitodepurazione: esperienze di laboratorio e avviamento di un impianto pilota.

La fitodepurazione è una tecnologia sempre più utilizzata ai fini del risanamento ambientale. Sono stati misurati in laboratorio alcuni parametri fisiologici (accrescimento delle radici, contenuto di pigmenti fotosintetici, attività fotosintetica, enzimi antiossidanti, contenuto di metalli pesanti) di piante di papiro allevate in soluzioni contenenti metalli pesanti a diverse concentrazioni. Contemporaneamente è stato avviato un impianto pilota di fitodepurazione con vasche contenenti esemplari di Typha latifolia e Cyperus alternifolius.
