Ground cover and leaf area index of maize and sugar beet crops
, 1997 Leaf area index (L) is an important variable characterizing the development of a crop and its exchanges with the atmosphere. Direct measurements are destructive and tedious.

Journal of Forest ScienceA lack or, conversely, an excess of water during the first growing seasons can bring about a slowdown in the growth of plants, their stagnation or even death. The necessary amount of water is not known for most hybrids of Paulownia.

Why does low intensity, long-day lighting promote growth in Petunia, Impatiens, and tomato? [PDF]
, 2008 Numerous reports demonstrate that low intensity, long-day (LD) lighting treatments can promote growth. However, there are conflicting suggestions as to the mechanisms involved.

A study of stomatal patterns in Plantago lanceolata L. Acer pseudoplatanus L. Sesleria caerulea L. in relation to environmental parameters [PDF]
, 1991 A baseline study of leaf stomatal density, stomatal indices, guard cell length and leaf area was made in three species; a grass, Sesleria caerulea L., a herb, Plantago lanceolata L., and a tree, Acer pseudoplatanus L.

Future atmospheric CO2 leads to delayed autumnal senescence
, 2007 Growing seasons are getting longer, a phenomenon partially explained by increasing global temperatures. Recent reports suggest that a strong correlation exists between warming and advances in spring phenology but that a weaker correlation is evident ...

Design and evaluation of multispectral LiDAR for the recovery of arboreal parameters [PDF]
, 2014 Multispectral light detection and ranging (LiDAR) has the potential to recover structural and physiological data from arboreal samples and, by extension, from forest canopies when deployed on aerial or space platforms.

Leaf economics and plant hydraulics drive leaf : wood area ratios
New Phytologist, 2019 Summary Biomass and area ratios between leaves, stems and roots regulate many physiological and ecological processes. The Huber value Hv (sapwood area/leaf area ratio) is central to plant water balance and drought responses. However, its coordination with key plant functional traits is poorly understood, and prevents developing trait‐based prediction
