In the initial analysis, we assumed that the ground-truth data obtained through lab-based leaf tissue analysis accurately reflected the foliar N content across the entire canopy. However, further consideration of the ground-truth data suggests that it likely contains significant noise, which could st...

Introduction Monitoring grapevine canopy architecture is critical for the assessment of growth, vigor and light transmission through the canopy and water requirements of plants. ...
27,28. Investigations of canopy nitrogen retention or release have mostly focused on the passive role of foliar surfaces to retain nitrogen compounds from the atmosphere (particularly the dry forms), which affects the input of these compounds to the soil. However, next-generation sequencing analyses...
One index that explicitly aims to separate canopy cover and CNC is CCCI, which uses a planar domain approach and employs one index (e.g. NDVI) to control for canopy cover and another index (e.g. NDRE) to capture the CNC signal, essentially using four wavebands. Despite this nuanced ...
In fact, trade-offs in vascular epiphytes have been found between allocation to traits that promote foliar water uptake and traits that promote water storage [22], indicating that vascular epiphytes can either hold onto water in leaves or readily uptake water via leaf surfaces—probably not both...
In general, fire stimulates plant growth through removing the standing dead litter aboveground and increasing the light interception in the canopy [5,6,7], while simultaneously eliminating substantial sources of foliar nitrogen pools available to herbivores [8]. Increased soil temperature in recently ...
If red SIF retrieval is needed, the spectrometer can be customized to cover the red region (650–730 nm). If the retrieval of both oxygen bands is intended, then the spectrometer can be customized to cover both O2A and O2B (centered around 687 nm) bands Sensors 2018, 18, 2063 4 of ...
During this time, known as the 'red' phase of attack, ACF, CBD and CBH remain unchanged, with reduced foliar moisture possibly causing an increase in crown fire potential [54,55]. However, few studies have documented the effects of beetle-caused tree mortality on fire behavior during this ...
