Over the last decades, most information on mechanisms underlying tolerance to drought has been gained by considering this stress as a single event that happens just once in life of plant, contrast what occurs under natural conditions where recurrent episodes are rule. Here we explored coffee (Coffea canephora) plants from broader perspective, integrating key aspects plant physiology and biochemistry. We show exposed multiple events displayed higher photosynthetic rates, which were largely...
Xylem embolism resistance varies across species influencing drought tolerance, yet little is known about the determinants of an individual conduit. Here we conducted experiment using optical vulnerability method to test whether conduits have a specific water potential threshold for formation and pre-existing in neighbouring alters this threshold. Observations were made on diverse sample angiosperm conifer through cycle dehydration, rehydration subsequent dehydration death. Upon after...
The resistance of xylem conduits to embolism is a major factor defining drought tolerance and can set the distributional limits species across rainfall gradients. Recent work suggests that proximity vessels neighbors increases vulnerability conduit. We therefore investigated whether relative vessel area correlates with intra- inter-generic variation in pairs or triplets from genera Acer, Cinnamomum, Ilex, Quercus Persea, adapted environments differing aridity. used optical method assess...
The overall coordination between gas exchanges and plant hydraulics may be affected by soil water availability source-to-sink relationships. Here we evaluated how branch growth mortality, leaf exchange metabolism are in coffee (Coffea arabica L.) trees drought fruiting. Field-grown plants were irrigated or not, maintained with full no fruit load. Under mild deficit, irrigation per se did not significantly impact but markedly reduced mortality fruiting trees, despite similar assimilate pools...
Abstract Xylem resistance to embolism is a key metric determining plant survival during drought. Yet, we have limited understanding of the degree plasticity in vulnerability embolism. Here, tested whether light availability influences leaves and stems. The optical method was used assess stem leaf Phellodendron amurense Ilex verticillata acclimated sun shade microenvironments within same canopy. In both species, found considerable segmentation xylem between stems, but only minor acclimation...
