Abstract:

Abstract Background and Aims Leaf size has considerable ecological relevance, making it desirable to obtain leaf size estimations for as many species worldwide as possible. Current global databases, such as TRY, contain leaf size data for ~30 000 species, which is only ~8% of known species worldwide. Yet, taxonomic descriptions exist for the large majority of the remainder. Here we propose a simple method to exploit information on leaf length, width and shape from species descriptions to robustly estimate leaf areas, thus closing this considerable knowledge gap for this important plant functio

Abstract:

This study aimed at determining the leaf area in Liquidambar styraciflua L. and at characterising the relationship between leaf area and leaf descriptors. The biological material was the species Liquidambar styraciflua L. We determined leaf area in 100 leaves (Figure 1) based on the size of median rib (L), leaf width at higher (W1) and lower (W2) lobe level, and on area constants (KA). The size of elements L, W1 and W2 were found by measuring with a precision of ±0.5 mm. Area constants in the species Liquidambar styraciflua L. were KA1 = 0.63, determined depending on leaf width at upper lobe w

The leaf area, as an important leaf functional trait, is thought to be related to leaf length and width. Our recent study showed that the Montgomery equation, which assumes that leaf area is proportional to the product of leaf length and width, applied to different leaf shapes, and the coefficient of proportionality (namely the Montgomery parameter) range from 1/2 to π/4. However, no relevant geometrical evidence has previously been provided to support the above findings.

Abstract:

SUMMARYLinear measurements of the length and maximum width of terminal leaflets of mungbean (Vigna radiata (L.) Wilczek) were made to estimate the whole trifoliate leaf area. The linear measurements were compared with the areas of leaflets and whole trifoliate leaves, determined using a leaf area meter. Five varieties were used in the study. Varieties differed in leaf shape and size, and equations were generated for each of the varieties to estimate the leaf area as a function of the product of the length and maximum width of the terminal leaflets, thus providing a means of nondestructive esti

Abstract:

Climate change is driving adaptive shifts within species, but research on plants has been focused on phenology. Leaf morphology has demonstrated links with climate and varies within species along climate gradients. We predicted that, given within-species variation along a climate gradient, a morphological shift should have occurred over time due to climate change. We tested this prediction, taking advantage of latitudinal and altitudinal variations within the Adelaide Geosyncline region, South Australia, historical herbarium specimens ( n = 255) and field sampling ( n = 274).

Abstract:

ABSTRACT The recent exploration of yacon demands scientific information for improving the crop production technology. This study aimed to set a leaf area estimate model for yacon plants, using non-destructive measurements of leaf length (L) and/or width (W). Sixty-four representative yacon plants were randomly selected in an experimental field during the full vegetative growth. One thousand leaves of various sizes were taken from those plants for setting and validating a model. The logarithmic model best fitted this purpose, the result of multiplying length by width being used as independent v

Abstract:

The shape of the rice flag leaf affects rice yield. Therefore, the detection of quantitative trait loci (QTLs) and alleles related to rice flag leaf shape is of great significance for rice yield improvement. Therefore, in 2019 and 2020, we carried out a genome-wide association study of flag leaf length (FLL), flag leaf width (FLW), flag leaf length–width ratio (FLR), and flag leaf area (FLA), considering 1.3 million single-nucleotide polymorphisms (SNPs) in 173 rice accessions, in order to investigate the effects of various genes on flag leaf shape.

Data for the predictor variables, length (L) and width (W) of leaf blades of BRS Zuri grass tillers, were collected in May 2018 in the experimental area of Embrapa Gado de Corte, Mato Grosso do Sul, Brazil. The predictor variables had high correlation values (P<0.001). In the analysis of adequacy of the models, the first-degree models that use leaf blade length (Model A), leaf width × leaf l

Differences in the shape of ribs can be observed in transverse sections of leaf blades of Italian ryegrass (<i>Lolium multiflorum</i> Lam.) var. 'Szelejewska', a diploid, has ribs similar to triangles, and 'Kroto', a tetraploid, has ribs which are more rounded, dome-like. A coefficient expressing width and surface increase of the leaf blade in relation to unribbed leaves has been determined. This coefficient (W) was calculated from the ratio of upper, wavy part of the leaf blade (g), to its width W=g/l. For Italian ryegrass the coefficient is from 1.5-1.46 and thus the width and th

The growth of leaf biomass can be predicted from an increase in the surface area and thickness of the leaves. Measurements of leaf biomass are approached with the fresh weight of the leaves. The relationship between biomass and leaf surface area commonly performed by regression analysis. The analysis requires assuming linear relationship between dependent variables and independent variables. Artificial Neural Network (ANN) is alternative that can be used to analyze the relationship of leaves and leaf biomass without requiring linear relationships.

Leaves are the nutritive organs of rice. Leaf shape influences rice photosynthesis, subsequently impacting yield. Gibberellins, GAs, are important hormones, but the way in which GAs regulate leaf width is largely unknown. This study focuses on the d18 mutant with broader leaves due to defective GA biosynthesis. Statistical analysis indicates broader leaves in the d18 mutant compared to the wild-type group. An examination of leaf cell morphology shows a higher count of secondary vascular bundles in d18 than in the wild-type group. RNA-seq analysis demonstrates significantly higher expression of
