Growth responses of nine provenances of Pinus brutia Ten. (Turkish red pine) to different levels of herbaceous competition and soil water
… cylindrica</i> L.) under either high or low soil water availability for two growing seasons. The study consisted of two separate experiments started at times with varying microenvironmental conditions and Turkish red pine (TRP) provenances. Diameter and secondary needle, stem, and root biomass …

Vines of different capacity and water status alter the sensory perception of Cabernet Sauvignon wines
… the effectiveness with which vine capacity and water status could be regulated as well as if they related to fruit quality and wine sensory perception. The treatments regulating vine size and water status were under-trellis groundcover, root manipulation, rootstocks, and irrigation. Treatments …

The influence of bed cover type (gravel vs plastic) on container-grown plants
… plant canopy temperatures; evapotranspiration, stem water potential, and plant widths were also determined. The objective of Expt. 2 and 3 was to determine the amount of water retained by the container substrate following irrigation and drainage on gravel or plastic bed covers. Pine bark-filled …

INVESTIGATION OF THE HYDRAULIC CHARACTERISTICS OF COASTAL REDWOODS THROUGH ANALYSIS OF WATER DYNAMICS
… during the climate change disturbs the global water cycle and harms the earth ecosystem. Because trees provide critical ecosystem services, it is important to understand how they respond to the changing environment to gauge the negative impact of the climate change on the ecosystem. Water is …

Stress Physiology of Phytophthora-canker Pathogens in Landscape Trees: impacts, mechanisms, and mitigation through biochar amendment
… benefits to plants including induction of systemic resistance to plant pathogens. Pathogens in the genus Phytophthora cause damaging diseases of woody species throughout the world. The objectives of the experiments described in the following chapters were to determine 1) what are the …

Effect of reduced irrigation on grapevine physiology, grape characteristics and wine composition in three Pinot noir vineyards with contrasting soils
The effect of water stress on grapevine performance has been extensively studied in different wine producing regions around the world, but little has ocurred in New Zealand. Pinot noir is the second most planted variety in the country and the most planted in Waipara. An improved understanding of …

Root restriction, under-trellis cover cropping, and rootstock modify vine size and berry composition of Cabernet Sauvignon
… the ability to reduce vegetative growth and vine water status. In the first experiment fruit-zone photosynthetic photon flux density (PPFD) was increased by 234% in RBG vines. Timed canopy management tasks indicated that RBG canopies required about half the labor time of NRM canopies. Anthocyanin …
