maintained turgor by rapidly closing stomata and reducing transpirational water loss. Although s-ABA effectively delays drought-induced wilting in a variety of floriculture crops, applications can result in leaf abscission and senescence symptoms that reduce
leaves through the transpiration stream ( Taiz and Zeiger, 2010 ). When ABA reaches guard cells, it binds to ABA receptors that activate an ion efflux, which reduces turgor pressure in the guard cells. Due to loss of turgidity, the guard cells become
Remote monitoring of leaf turgor pressure of grapevines subjected to different irrigation treatments using the leaf patch clamp pressure probe Aust. J. Grape Wine Res. 16 405 412 Saha, U.K. Papadopoulos, A.P. Hao, X. Khosla, S. 2008 Irrigation strategies
less water stress during midday sampling in 2010. The –40 kPa treatment irrigated at a much greater frequency (44 events) than all others in 2010 ( Table 1 ). Leaf RWC, which measures water in leaves relative to a state of full turgor, may remain stable
Overhead mist revolutionized the propagation industry by providing reliable means to manage transpirational water losses by leafy stem cuttings. This system slows transpiration of cuttings primarily by decreasing leaf temperatures through
plotted to the corresponding amount of ethylene biosynthesis measured each day. Each point represents the data determined for one specific day of the shelf life period. Considering the change in ethylene production in relation to the daily I AD , it is
morphology and physiology. However, the capacity to adapt to drought stress is highly variable among plant species ( Taiz et al. 2015 ). Plants may respond to drought stress by reducing leaf area to restrict transpirational water loss. For instance, carnation
Botrytis ( Botrytis cinerea ), a necrotrophic plant pathogen, infects more than 200 hosts worldwide, causing significant losses within agricultural systems ( Williamson et al. 2007 ). Bedding plant producers experience problems with Botrytis
began 1 week after inoculation. The number of trees with initial (loss of turgor on leaves, “green-wilting”) or advanced external symptoms (leaves showing desiccation, “brown wilting”) in the inoculated branch was recorded every 2 or 3 d up to 1 month
and Dufault, 2001 ), often resulting in plant loss due to chilling injury (CI) ( Loy and Wells, 1983 ; Waterer, 1993 ). Although high-tunnel production of warm-season crops has increased in the northeastern United States, Vescera and Brown (2016
