Variability in leaf and crown morphology correlated with light availability in five natural populations of Quercus castaneifolia C.A. Mey

open access: yesJournal of Forest Science, 2017
In this study, we investigate seedlings of Quercus castaneifolia C.A. Mey, from five different provenances for the research on leaf and crown morphological variations in relation to a light gradient under controlled conditions in a greenhouse.

Leaf area index of potato crop under three nitrogen fertilization treatments

open access: yesAgronomía Colombiana, 2017
Nitrogen fertilization has considerable effects on growth and yield of the potato crop. Additionally, leaf expansion is one of the most important growth parameters that can be used to optimize the management of agroecological resources.

The Effects of Water Stress on Cotton Leaf Area and Leaf Morphology

open access: yesKahramanmaraş Sütçü İmam Üniversitesi Tarım ve Doğa Dergisi, 2023
The most important effect of water stress on plants is that it reduces leaf area and leads to changes in leaf morphology. Decreased leaf area results in reduces crop yield through the reduction in photosynthesis. This study investigates the effects of the decrease in leaf area on seed cotton yield, evapotranspiration (ET), water use efficiency (WUE ...

Joint Estimation of Leaf Area Density and Leaf Angle Distribution Using TLS Point Cloud for Forest Stands

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
The foliage density $(u_l)$ and the leaf angle distribution (LAD) are important properties that impact radiation transmission, interception, absorption and, therefore, photosynthesis.

A Rapid Method of Leaf Area Determination [PDF]

open access: yesNature, 1951
RECENT physiological studies on nutrition and growth have shown that leaf area is a reliable index of growth factors determining dry matter accumulation, carbohydrate metabolism, yield and quality of crops1–9,12. Various methods have therefore been devised for measuring the total leaf surface on a growing plant.
