A Rapid Method of Leaf Area Determination [PDF]

Nature, 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.

Allometric models for estimating the leaf area of lisianthus (Eustoma grandiflorum) using a non-destructive method

Revista Ceres, 2022
Lisianthus (Eustoma grandiflorum) is a cut flower grown due to the wide diversity of colors and longevity in the post-harvest. The leaf area measurement is fundamental in plants because the leaves are directly related to several processes such as ...

Canopy Architecture and Sun Exposure Influence Berry Cluster–Water Relations in the Grapevine Variety Muscat of Alexandria

Plants
Climate-change-related increases in the frequency and intensity of heatwaves affect viticulture, leading to losses in yield and grape quality. We assessed whether canopy-architecture manipulation mitigates the effects of summer stress in a Mediterranean ...

Conversion of total leaf area to projected leaf area in lodgepole pine and Douglas-fir [PDF]

Tree Physiology, 1998
Three definitions of leaf area index (LAI) in the literature have no predictable relationship with each other. Factors were derived for converting total LAI to projected LAI of horizontal leaves and to projected LAI for inclined leaves of lodgepole pine (Pinus contorta Dougl. var. latifolia Engelm.) and coastal Douglas-fir (Pseudotsuga menziesii (Mirb.)

Relationships between leaf traits and morphological attributes in one-year bareroot Fraxinus angustifolia Vahl. seedlings

Annals of Forest Research, 2014
Leaf traits were investigated as morphological attributes for quality estimation of one-year-old bareroot seedlings of Fraxinus angustifolia Vahl. Leaf traits (number of simple – NSL and compound leaves – NCL, leaf average – ALA and total area – TLA and ...

Convergence in leaf size versus twig leaf area scaling: do plants optimize leaf area partitioning? [PDF]

Annals of Botany, 2016
Background and Aims Corner’s rule states that thicker twigs bear larger leaves. The exact nature of this relationship and why it should occur has been the subject of numerous studies. It is obvious that thicker twigs should support greater total leaf area (Atwig) for hydraulical and mechanical reasons.

Functional traits of tree saplings and adults in a tropical cloud forest restoration context

Botan‪ical Sciences, 2020
Background: The use of tree species’ functional traits is a promising approach in forest restoration. However, some traits may change during ontogeny. Questions: Does intraspecific variation in functional traits occur between sapling and adult stages?

Effects of mildew (Erysiphe graminis) on green leaf area of Zephyr spring barley, 1973

, 1976
A single spray of tridemorph on 1 June almost doubled leaf area index of Zephyr barley during much of the second half of June. Increases in leaf area duration before ear emergence seemed important in these plots, because they yielded much better than ...
