Association of carbon isotope discrimination with leaf gas exchange and water use efficiency in maize following soil amendment with superabsorbent hydrogel

Plant, Soil and Environment, 2018
The correlation of carbon isotope discrimination (△13C) with photosynthetic gas exchange and water use efficiency (WUE) in maize was investigated under low rainfall conditions with or without superabsorbent polymer (SAP).

Functional imaging of plants: A nuclear magnetic resonance study of a cucumber plant [PDF]

, 2002
Functional magnetic resonance imaging was used to study transients of biophysical parameters in a cucumber plant in response to environmental changes. Detailed flow imaging experiments showed the location of xylem and phloem in the stem and the response ...

A systematic review on the combined effects of deficit irrigation and soil amendment with super-absorbent polymer on crop yield and water productivity

Frontiers in Agronomy
Deficit irrigation (DI) and soil amendment with super-absorbent polymer (SAP) are viable strategies to reduce agricultural water demand. This review paper aims to discuss the status quo of research studies on this topic focusing on their effects on yield

BOUND WATER IN PLANT SAP AND SOME EFFECTS OF TEMPERATURE AND NUTRITION THEREON [PDF]

Plant Physiology, 1941
Most plants developing under very favorable conditions for growth are tender and exhibit little resistance to frost damage. Certain plants, however, are capable of developing the capacity to resist freezing and are then said to be hardened. While exposure to low temperature is the principal natural and artificial agency producing such an effect ...

Preparation and Characterization of Supramolecular Bonding Polymers Based on a Pullulan Substrate Grafted with Acrylic Acid/Acrylamide by Microwave Irradiation

ChemEngineering
A microwave technique was used to prepare a superabsorbent polymer (SAP) by grafting two hydrophilic monomers onto a polysaccharide substrate. The monomers used were acrylic acid (AA) or acrylamide (AM) and were grafted onto a pullulan (PUL) substrate to

Limitations to using phloem sap to assess tree water and nutrient status

Tree Physiology, 2018
Rapid, reliable tools are needed to infer physiological and nutritional health for managing forest systems. Understanding the processes governing tree health is central to the development of these tools. Non-foliar approaches such as the collection of phloem sap reflect processes governing both the use and acquisition of plant water and nutrients at a ...

SAP raktárkezelő rendszer

, 2023
Ismertettem, hogy honnan hova fejlődött az SAP, mire használják, és milyen nagyobb cégek használják igazán az SAP-t. Bemutattam az SAP különböző részeit és későbbiekben részleteztem a dolgozatomra kihatással lévő MM modulra és az EWM rendszerre ...
