Sap flux and stem radius variations in mature Cedrus libani trees during the growing season

Variations in sucrose,total free amino acids and nitrates of sugarbeets during the growing season under high nitrogen untritional conditions

Historical changes of temperature and vapor pressure deficit during the crop growing season in Iran

Climate change variables have rarely been analyzed specifically for the growing season of crops. In this study, changes in minimum (Tmin) and maximum temperature (Tmax), daily maximum saturated vapor pressure (VPsat) and estimated daily VPD weighted for transpiration (VPDtran) were examined at five locations in Iran over 40 years during the growing seasons of chickpea and maize. The results of ...

Influence of environmental factors on the sap flux density of mango trees under rain-fed cropping systems in West Africa

Xylem sap flux density (Fd) was measured, on a 43-year-old (mature) and three 4-year-old (young) mango (Mangifera indica L.) trees, using Granier-type probes. The relative influences of environmental variables were examined under well-watered condition. Circumferential variation in Fd was also investigated by placing sensors on the north, south-west and south-east sides of the mature tree. Sap ...

Spatial and Temporal Variations in Temperate Forest Soil Carbon Dioxide during the Non-growing Season

In the Whitehall Forest of Georgia during the 1985-86 non-growing season soil CO, varied with soil depth, varied spatially at constant depth, and varied temporally with changing environmental conditions. Variations with depth in the upper 1.4 m of the soil were of greater magnitude than temporal variations and spatial differences at 30 cm depth were of lesser magnitude. Mean soil CO, in evergre...

Temporal Variations of Runoff and Sediment Generation during the Growing Season in Rain-Fed Lentil: A Case Study in Tikmehdash Region of Eastern Azerbaijan

Extended abstract 1- INTRODUCTION The contribution of crop cover to reducing runoff and erosion depends on the type, height, density and stage of plant growth. The literature review indicates that because of the different life forms, the effect of plants on the reduction of runoff and erosion are different at different growth stages [13]. However, no comprehensive studies have been conduc...
