The impact of water deficit on stilbene biosynthesis in wine grape (Vitis vinifera) berries was investigated. Water deficit increased the accumulation of trans-piceid (the glycosylated form of resveratrol) by 5-fold in Cabernet Sauvignon berries but not in Chardonnay. Similarly, water deficit significantly increased the transcript abundance of genes involved in the biosynthesis of stilbene prec...

I grant The Pennsylvania State University the nonexclusive right to use this work for the University's own purposes and to make single copies of the work available to the public on a not-for-profit basis if copies are not otherwise available. ABSTRACT Pressure to decrease reliance on surface-water storage has led to increased interest in aquifer storage and recovery (ASR) systems, where borehol...

We monitored dynamics of stem water deficit (ΔW) and needle water potential (Ψ) during two consecutive growing seasons (2011 and 2012) in a dry inner Alpine environment (750 m above sea level, Tyrol, Austria), where Pinus sylvestris, Picea abies and Larix decidua form mixed stands. ΔW was extracted from stem circumference variations, which were continuously recorded by electronic band dendromet...

a greenhouse experiment was performed in the framework of a completely randomized design and a factorial arrangement to evaluate the effect of arbuscular mycorrhizal fungi (amf) on growth and on root antioxidant enzyme changes of two citrus rootstocks (sour orange and rough lemon). the experimental factors were: mycorrhizal treatments at two levels (inoculation with glomus mosseae vs. control) ...

This research was carried out to study the effect of deficit irrigation and saline water on yield and yield components of maize (KSC-500) during different growth stages for Ahwaz climatic condition in the farming years 2010-2011. This research performed in three independent experiments according to a randomized complete block design with split plot layout in three levels of irrigation water and...

The climate unpredictability causes long periods of drought, becoming the main risk factor in soybeans production fields and consequent losses to farmers Brazil worldwide. As sessile organisms, plants are constantly challenged by a wide range environmental stresses, including drought. Growth constraints stress due these changes result reduced yield significant harvesting losses. response abioti...
