Descripción
In this study, we investigated the responses to water scarcity after the post-transplant shock in six sclerophyllous species established in a Mediterranean-type climate site severely burned by fire. Seedlings of the species Acacia caven, Lithraea caustica, Quillaja saponaria, Escallonia pulverulenta, Peumus boldus and Colliguaya odorifera were cultured in the nursery on 140 mL pots and then planted in the field under tree shelters and submitted to two irrigation treatments during summer (2 L-1 week-1 seedling-1 cf. no watering). Species differed by irrigation treatment in survival, stomatal conductance, and transpiration, with P. boldus and E. pulverulenta exhibiting the lowest values in the treatment with no watering. This suggests that young seedlings of both species have not the capacity to survive during dry summers in Mediterranean-type climates unless irrigations are increased in frequency and quantity.
