EVALUATION OF THE EXTINCTION COEFFICIENT OF THE ABTS DERIVED RADICAL CATION
(Sociedad Chilena de Química, 2002)
Characterization of genetic coefficients of durum wheat (Triticum turgidum L. ssp. durum) ‘Llareta-INIA’ and ‘Corcolén-INIA’
The genetic coefficients, representative of a crop, are necessary to use growth models; in many cases the range of the species is known, but there are no specific values for varieties. Durum wheat (Triticum turgidum L. ...
Use of lignin extracted from different plant sources as standards in the spectrophotometric acetyl bromide lignin method
(Amer Chemical Soc, 2011)
A nongravimetric acetyl bromide lignin (ABL) method was evaluated to quantify lignin concentration in a variety of plant materials. The traditional approach to lignin quantification required extraction of lignin with acidic ...
In Field Assessment on the Relationship between Photosynthetic Active Radiation (PAR) and Global Solar Radiation Transmittance through Discontinuous Canopies
(Instituto de Investigaciones Agropecuarias, INIA, 2011)
Measurement method of high spectral resolution lidar with a multimode laser and a scanning Mach-Zehnder interferometer
(OSA - The Optical Society, 2017-07)
A simple high spectral resolution lidar technique using a multi-longitudinal mode laser is proposed for measuring aerosol extinction and backscattering coefficients. A scanning interferometer having the same free spectral ...
Tropical forest light regimes in a human-modified landscape
Light is the key energy input for all vegetated systems. Forest light regimes are complex, with the vertical pattern of light within canopies influenced by forest structure. Human disturbances in tropical forests impact ...
Phenomenon of primary and secondary extinction in textured material
(Revista Mexicana de Física, 2009)
Relações radiométricas no terço superior da copa de cafeeiro
(Instituto Agronômico de Campinas, 2010-01-01)
Com o objetivo de obter os coeficientes de transmissão e de extinção da radiação fotossinteticamente ativa determinou-se o índice de área foliar e mediu-se a radiação fotossinteticamente ativa transmitida no terço superior ...
