Exogenous application of salicylic acid to control coffee rust

open access: yesActa Scientiarum: Biological Sciences, 2021
The exogenous application of salicylic acid can induce plant resistance against pathogens. However, little is known about the potential uses of this bioregulator for controlling coffee diseases.

Morphogenetic and structural characteristics of signal grass in response to liming and defoliation severity [PDF]

open access: yesPesquisa Agropecuária Tropical, 2018
ABSTRACT The control of soil acidity through liming and the adoption of adequate management are essential to the maintenance of pastures productivity. The morphogenetic and structural characteristics of Urochloa decumbens cv. Basilisk, in canopies with (0.7 t ha-1 and 1.0 t ha-1) or without liming and subjected to severe or lenient cuttings (stubble ...

Relationship between defoliation and disease severity in citrus canker.

open access: yesJapanese Journal of Phytopathology, 1979
The relationship between disease severity and leaf abscission was analysed with leaves of Natsudaidai (Citrus Natsudaidai) infected by Xanthomonas citri. When young shoots were inoculated by spray method under field conditions, defoliation occurred on more than 80% of leaves when lesions covered as much as 10% of leaf surface area.

Environmental Impact of Silicic Magmatism in Large Igneous Province Events

open access: yesGeophysical Monograph Series, Page 133-151., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Root production in a subtropical pasture is mediated by cultivar and defoliation severity [PDF]

open access: yes, 2019
Abstract Background Grasslands occupy significant land area and account for a large proportion of the global soil carbon stock, yet the direct effects of grazing and genotypic composition on relationships between shoot and root production are poorly resolved.

Defoliation Dynamics on Grazing Horizons in Pastures Intercropped by Panicum maximum, Brachiaria brizantha, and Brachiaria decumbens

open access: yesTropical Animal Science Journal, 2020
The aim of this study was to quantify and verify the defoliation dynamics process of the Panicum maximum, Brachiaria brizantha, and Brachiaria decumbens intercropping during the formation of four grazing horizons in lenient grazing intensities and high ...

Sex-specific responses of Populus deltoides to defoliation

open access: yesActa Societatis Botanicorum Poloniae, 2017
There has been an increasing interest in understanding the differential effects of sexual dimorphism on plant stress responses. However, there is no clear pattern in the responses of the sexes to defoliation.
