Stomatal responsiveness to evaporative demand (air vapour pressure deficit (VPD)) ranges widely between species and cultivars, and mechanisms for stomatal control in response to VPD remain obscure. The interaction of irrigation and soil moisture with VPD on stomatal conductance is particularly difficult to predict, but nevertheless is critical to instantaneous transpiration and vulnerability to...

Soil moisture is a spatially heterogeneous quantity in the McMurdo Dry Valleys of Antarctica that exerts a large influence on the biological community and on the thermal state of Dry Valleys permafrost. The goal of this project was to determine whether hyperspectral remote sensing techniques could be used to determine soil moisture conditions in the Dry Valleys. We measured the spectral reflect...

Temporal and spatial variations in the water status of walnut trees (Juglans regia L.) and the soil in which they were growing were traced by analyzing the differences in hydrogen isotopes during spring and summer in a 7-year-old walnut stand. Walnut root dynamics were measured in both dry and wet seasons. Walnut roots were mainly distributed in the upper soil (0-30 cm depth), with around 60% o...

A preliminary analysis of fields around 20 mainly radio– quiet QSOs (RQQs) at intermediate redshift is summarized. We find overdensities of faint sources around 50% of our observed QSOs suggesting that they are located in groups or even clusters of galaxies.

Ecohydrology 2017;e1825. https://doi.org/10.1002/eco.1825 Abstract Topography may mitigate drought effects on vegetation along a hillslope gradient through redistribution of soil moisture. We examined the interaction of topography, climate, soil moisture, and transpiration in a low‐elevation, mixed‐hardwood forest in the southern Appalachian Mountains. The effects of meteorological variation (w...

according to high importance of sodding for fast creating green beds in all seasons, this experiment carried out with aimidentifying suitable substrate and covering plant including two lawn genus and dichondra with blend seed. the trial carried out as factorial experiment with three factors based on complete block design in three replications. experimental factors consisted of planting networks...

The vigour and growth of seedlings of CRIC60 cultivar of coconut were studied in different irrigation treatments during the drought period, in a sandy soil in the dry zone. Nine irrigation treatments including a control with no watering were tested. Larger number of casualties were observed in the control while none in the irrigated plots. The best irrigation treatments in order of response wer...
