Defoliation reconsidered?

open access: yes, 2015
Since the 1980s defoliation (often assessed by means of crown transparency) is the most used indicator of tree condition adopted in Europe. It has been criticized for its subjectivity and scarce relation with meaningful endpoints. Here we collated the results of three different studies carried out in France and Italy to investigate the relationship ...

Soybean tolerance to defoliation at the vegetative and reproductive stages as a function of water restriction

open access: yesActa Scientiarum. Agronomy, 2022
Water deficiency reduces leaf expansion and photosynthetic efficiency, potentially reducing the ability to withstand leaf area (LA) loss. This study aimed to evaluate the effects of water restriction on soybean tolerance to defoliation in the vegetative
