All terrestrial plants face the trade-off between water loss and carbon gain. Avoiding excessive water loss via stomatal closure during drought inevitably leads to reduced photosynthesis and carbohydrate production, which reduces source strength. Also, the turgor-related reduction of growth is one of the first drought … Visa mer Recent forest mortality events (Allen et al., 2010), combined with climate predictions of increasing drought severity and frequency in many areas (Allison et al., 2009), have motivated a new focus area of plant mortality … Visa mer The currently most accepted theory of phloem transport, the Münch hypothesis (Münch, 1930; see also Knoblauch and Peters, 2010) states that carbohydrates needed for … Visa mer The classical impermeable conduit model predicts that phloem transport could cease during drought even with active sources and sinks because of viscosity blockage in the … Visa mer The Hagen–Poiseuille law was originally developed to describe laminar flow in cylindrical tubes of impermeable walls (Bird et al., 2002) and the classical view of phloem transport, … Visa mer Webb12 feb. 2024 · Abstract We report drought impacts on phloem transport have attracted attention only recently, despite the well-established, and empirically verified theories on drought impacts on water transport in plants in general. This is because studying phloem transport is challenging.
