Dust Capturing Capacity of Woody Plants in Clean Air Zones throughout Taiwan

open access: yesAtmosphere, 2021
To exploit the ability of vegetation to capture particulate matter (dust) from the air and improve air quality, 546 clean air zones (CAZs) consisting of various types of urban green space have been established in Taiwan.

Long-term effects of red- and blue-light emitting diodes on leaf anatomy and photosynthetic efficiency of three ornamental pot plants [PDF]

open access: yes, 2017
Light quality critically affects plant development and growth. Development of light-emitting diodes (LEDs) enables the use of narrow band red and/or blue wavelengths as supplementary lighting in ornamental production.

Non-Destructive Estimation of the Leaf Weight and Leaf Area in Common Bean

open access: yesAgronomy, 2022
Regression models to predict leaf area and leaf weight in common bean (Phaseolus vulgaris) were fitted using the three leaflets of the leaves. A total of 1504 leaves from 40 genotypes were collected, covering a large range of leaf sizes.

Morphological Differences among Apple Leaf Types [PDF]

open access: yesHortScience, 1992
Leaf characteristics of mature `Sturdeespur Delicious'/MM.106 apple trees (Malus domestica Borkh.) were studied in two experiments. In 1989 canopy foliage on fruiting trees was divided into shoot leaves, leaves on nonfruiting spurs, and leaves on fruiting spurs.

Which morphological characteristics are most influenced by the host matrix in downy mildews? : A case study in Pseudoperonospora cubensis [PDF]

open access: yes, 2012
Before the advent of molecular phylogenetics, species concepts in the downy mildews, an economically important group of obligate biotrophic oomycete pathogens, have mostly been based upon host range and morphology.
