Morphology and histochemistry of the glandular trichomes of Lippia scaberrima (Verbenaceae).

abstract：BACKGROUND AND AIMS:Extreme water stress episodes induce tree mortality, but the physiological mechanisms causing tree death are still poorly understood. This study tests the hypothesis that a potted tree's ability to survive extreme monotonic water stress is determined by the cavitation resistance of its xylem tissue....
