Drought stress in provenances of Lupinus elegans from different altitudes

The response of plants to altitudinal gradients depends on several factors and might differ among life strategies. Understanding these responses is highly relevant for management of forest species, particularly under climate change scenarios. We explored the response to drought of different provenan...

We explored the response to drought of different provenances of Lupinus elegans, obtained from an altitudinal gradient.

Survival among provenances presented an altitudinal pattern, where those belonging to higher sites exhibited greater survival. Provenances from lower altitudes, coming from drier and warmer sites, exhibited poorer survival against drought stress. Overall, our results indicate that there are differences among provenances, but since this species is a short lived perennial (five years on average), it is more sensitive to microclimate than to conditions determined for large scale patterns such as altitudinal gradients.
