Improving Irrigated and Dryland Agriculture Via Xylem, Stomata, and Leaf Traits

Irrigation Dryland Agriculture

United States Department of Agriculture (USDA) Agricultural Research Service (ARS)

Titre : Improving Irrigated and Dryland Agriculture Via Xylem, Stomata, and Leaf Traits

Identification : 3012-13000-010-17-S

Pays : Etats Unis

Durée : Start Date : Sep 1, 2020 // End Date : Aug 31, 2021

Location : Water Management and Systems Research : Fort Collins, CO

Objectifs
The long-term goals of this cooperative research project are : 1) Determine what internal (xylem conduit) and external (branching, venation patterns) water transport traits allow plants to operate at lower water potential and/or improve water transport efficiency. 2) Determine the optimal coordination of xylem, stomata, and leaf traits that will maximize either seasonally-integrated water use efficiency, or soil water extraction, which are the cornerstone traits of drought tolerance and drought avoidance. 3) Determine the physiological costs and risks (i.e., tradeoffs) that arise when xylem, stomata, and leaf traits are manipulated to improve water use efficiency or soil water extraction.
