The goal of this study was to determine the effects of atmospheric demand on both plant water relations and daily whole-tree water balance across the upper limit of a cloud forest at the mean base height of the trade wind inversion in the tropical trade wind belt. We measured the microclimate and water relations (sap flow, water potential, stomatal conductance, pressure-volume relations) of Met...
the world is facing a dwindling supply of water, therefore deficit irrigation is becoming more of a necessity than a choice. partial rootzone drying (prd) is a new water saving irrigation technique where at each irrigation time only one part of the rootzone is watered. the un-irrigated part is watered during the next irrigation. we explored the potential of prd for `petopride´ processing tomato...
Aquaporins are membrane channel proteins ubiquitously present in all kingdoms of life. Although aquaporins were originally discovered as water channels, their roles in the transport of small neutral solutes, gasses, and metal ions are now well established. Plants contain the largest number and greatest diversity of aquaporin homologs with diverse subcellular localization patterns, gating proper...
Spectral reflectance indices can be used to estimate the water status of plants in a rapid, non-destructive manner. Water spectral indices were measured on wheat under a range of water-deficit conditions in field-based yield trials to establish their relationship with water relations parameters as well as available volumetric soil water (AVSW) to indicate soil water extraction patterns. Three t...
Mathematical models of the plant root growth zone already exist, but there is a lack of experimental evidence to support the model results. It is our belief that these models, specifically the Osmotic Model presented by Silk and Wagner [7], need a component representing a pressure-driven bulk flow of water through the phloem to the region in the growth zone where phloem is just beginning to fun...
Aquaponic is a combination of fish and plant cultivated in recirculating systems. Fish culture in closed recirculating systems causes organic waste accumulation in the system. If these metabolites are used for plant nutrition, they are not mere waste, but have economical value and however benefit the fish production systems. Most aquaponic systems are designed as perlite-filled media, thin laye...
Successful management of forest systems requires a deeper understanding of the role of ecophysiological traits in enabling adaptation to high temperature and water deficit under current and anticipated changes in climate. A key attribute of leaf water relations is the water potential at zero turgor (πtlp), because it defines the operating water potentials over which plants actively control grow...
