Fine mesh (2545 m) has been used to separate root systems and allow only hyphal penetration and linkages but no root contact between plants. In many studies, nitrogen from N2-fixing mycorrhizal plants transferred to non-N2fixing mycorrhizal plants (one-way N-transfer). In a few studies, N ...
Nitrogen nutrition has great influences not only on the yields, but also on the chemical components of the plants. Nitrate nitrogen is generally found to be superior to ammonium nitrogen as the nitrogen source for higher plants (1). As reported in the previous paper (2), young plants of sug...
as a dominant macronutrient for plant growth, can largely affect flowering time. A complex network integrates multiple environmental signals consisting of N status and photoperiod condition into internal regulation of flowering time in plants. So far,...
aSoil provides plants with nitrogen, potassium and phosphorous -- three macronutrients essential to plant life. Too much nitrogen, however, encourages rapid stem and foliage growth but does little for flowers because plants put their energy toward shoot development and fail to produce buds and flower...
(Smil, 1999). Nitrogen cannot be used in its natural state; it needs to be “fixed” first for humans to use it. The main process that “fixes” nitrogen is that when lightning strikes, a chemical reaction takes place, and the plants roots absorb the nitrogen. Animals (such as humans)...
Kjeldahl digestion and Dumas combustion have been used as reference methods for N determination in plants, but they are destructive and time consuming. By using spectroradiometers, reflectometers, imagery from satellite sensors and digital cameras, optical properties have been measured to estimate N in...
Current studies suggest that many plants are able to take up not only inorganic nitrogen (N) but also organic N. We used the novel tool of position-specific isotope labeling to improve the quantification of intact amino acid uptake and to deepen our understanding of the processes occurring at ...
Illumina’s RNA-sequencing platform was used for transcriptomic exploration of genes expression to investigate the response of nitrogen nutritional stress in plants. It has been reported that the amino acid transporters in wheat plants play important role to transport nitrogen for development and a ...
In the case of V-PHs, the final composition of biostimulants, as well as the results achievable in plants after their application, are strongly influenced by the botanical origin of the biomass used in the production process. This review aims to present the most recent research on the ...
Nitrogen is an essential nutrient for plant growth and development but is unavailable in its most prevalent form as atmospheric nitrogen. Plants instead depend upon combined, or fixed, forms of nitrogen, such as ammonia and nitrate. Much of this nitrogen is provided to cropping systems in the fo...
