Tocopherol oil concentration in field-grown sunflower is accounted for by oil weight per seed
(Springer, 2004-12)
Tocopherols are natural antioxidants that increase the stability of fat-containing foods and perform important biological activities. Significant variations (389 to 1873 μg g oil-1) in the total tocopherol concentration ...
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 ...

Maize water use efficiency and evapotranspiration response to N supply under contrasting soil water availability
(Elsevier Science, 2015-07)
Water use efficiency (WUEg), the quotient between grain yield and crop evapotranspiration (ET), might be increased in maize crops (Zea mays L.) due to N supply. Most research has focused on understanding grain yield response ...
Land cover and precipitation controls over long-term trends in carbon gains in the grassland biome of South America
(Ecological Society of America, 2015-10)
Carbon gains are a key aspect of ecosystem functioning since they represent the energy available for upper trophic levels. Carbon gains (or primary production) are strongly correlated with other ecosystem attributes such ...
Efficiency of nitrogen sources and rates on growth and dry matter yield of tifton 85
(Universidade Estadual Paulista (UNESP), 2016)
Defoliation affects soybean yield depending on time and level of light interception reduction
(Southern Cross Publishing, 2012-07)
Light interception (mainly due to defoliation) during the critical growth periods of soybean may be a suitable index for calculating the economic injury level (ELI) rather than measuring the insect population or percentage ...

Eco-physiological processes underlying maize water use efficiency response to plant density under contrasting water regimes
(Elsevier Science, 2020-09)
This study quantified maize (Zea mays L.) water use efficiency for grain yield (WUEg) in response to plant density under contrasting water regimes; and focused on relevant eco-physiologial processes underlying the responses ...
