Saffron production will be increased in arid regions by providing sufficient water through appropriate agronomic strategies. Therefore, in this investigation the impact of different rates of super absorbent polymer (SAP) including 0,10, 20, 30, 40 and 50 kg ha-1 was studied on saffron flowering traits during two growth cycles. Results showed that the influence of experimental factor was signifi...

Vascular plants transport energy in the form of sugars from the leaves where they are produced to sites of active growth. The mass flow of sugars through the phloem vascular system is determined by the sap flow rate and the sugar concentration. If the concentration is low, little energy is transferred from source to sink. If it is too high, sap viscosity impedes flow. An interesting question is...

Automatic model generation, the consequential reduction of problem solving cycles and the need for a higher degree of data integration have long been characterized as significant challenges in the field of simulation of manufacturing systems. Especially operationally used manufacturing simulation models require a high degree of modeling detail and thus depend on a significant amount of input da...

Hardy plants can maintain their normal physiological metabolism in cold winter and against the cold weather by regulating themselves. Around this natural phenomenon, a large number of researchers conducted researches on cold resistance of hardy plants and the mechanism of cold resistance respectively from the point of cell membrane structure and characteristics, physiological metabolism, growth...

INTRODUCTION Several major changes in sap collection equipment and methods have occurred over the past 10-15 years. The introduction of small spouts, a transition in composition from polyvinyl chloride (PVC) tubing to polyethylene (PE) tubing, and improvements in fittings have occurred. These changes, along with continued modifications in tubing system design, installation, and maintenance as w...

Climate modelling studies predict that the rain forests of the Eastern Amazon basin are likely to experience reductions in rainfall of up to 50% over the next 50-100 years. Efforts to predict the effects of changing climate, especially drought stress, on forest gas exchange are currently limited by uncertainty about the mechanism that controls stomatal closure in response to low soil moisture. ...

We measured diel patterns of stem surface CO 2 efflux ( E s , m mol m 2 s 1 ), sap velocity ( v s , mm s 1 ) and xylem CO 2 concetration ([CO 2 ]) ( X s , %) in 8-year-old loblolly pine trees during the spring to determine how v s and X s influence E s . All trees showed a strong diel hysteresis between E s and stem temperature, where at a given temperature, E s was lower during the day than at...

enterprise resource planning (erp) has become the most strategic tool for an organization to employ. a leading erp solution is sap®. it has been employed by organizations to enable them to collaborate on different projects and to integrate all aspects of operations. just as organizations have adopted erp solutions, they employed quality initiatives that are designed to help organizations maximi...
