Abstract The concept of a geometric series (GS) plays an important role in mathematics. However, it has been neglected describing biological size series. Herein, we show that GS describes the nonreproductive (perianth) parts flowers four Magnoliaceae species and two Rosaceae leaves 60 Alangium chinense Shibataea chinensis shoots. sorted areas floral formed sequence was fitted by with mean quotients adjacent members as common ratio GS. absolute percent error (MAPE) used to measure goodness...
Abstract There is a lack of research on whether tree size affects lamina and petiole biomass allocation patterns, whereas the trade‐off between leaf allocated to significance when considering hydraulic mechanical function as whole. Here, Camptotheca acuminata Decne was selected for study because availability trees differing in growing under same conditions. A total 600 leaves two groups 300 per group height trunk diameter were collected. The fresh mass (LFM), dry (LDM), area (LA), (PFM),...
Measuring the inequality of leaf area distribution per plant (ILAD) can provide a useful tool for quantifying influences intra- and interspecific competition, foraging behavior herbivores, environmental stress on plants’ above-ground architectural structures survival strategies. Despite its importance, there has been limited research this issue. This paper aims to fill gap by comparing four indices measure ILAD, using household income that are commonly used in economics, including Gini index...
Stomatal pore area and density determine the capacity for gas exchange between leaf interior atmosphere. is given by profile formed two guard cells, cumulative stomatal characterizes of surface occupied stomata. The areas all stomata captured in a micrograph are sorted ascending order to form sequence, which referred as sequence here. In total, 360 leaves 12 Magnoliaceae species with 30 each were sampled. For leaf, 662 μm × 444 fields view (micrographs) on right width axis. micrograph,...
The “leafing intensity premium” hypothesis proposes that leaf size results from natural selection acting on different leafing intensities, i.e., the number of leaves per unit shoot volume or mass. scaling relationships among various above-ground functional traits in context this are important for understanding plant growth and ecology. Yet, they have not been sufficiently studied. In study, we selected four bamboo species genus Indocalamus Nakai measured total fresh mass culm, non-leaf mass,...
In nature, the two-dimensional (2D) profiles of fruits from many plants often resemble ellipses. However, it remains unclear whether these strictly adhere to ellipse equation, as natural shapes resembling ellipses are actually better described superellipses. The superellipse which includes an additional parameter n compared can generate a broader range shapes, with being just special case superellipse. To investigate 2D by or superellipses, we collected total 751 mature and undamaged 31...
The size of floral organs is closely related to the successful reproduction plants, and corolla is, some extent, indicative organs. Petals are considered be homologous leaves, so we also attempted estimate area a single petal using method that typically employed for estimating leaf (i.e., Montgomery equation). Additionally, estimated total per flower (AT; i.e., whole area) designed shoot Montgomery–Koyama–Smith equation (ME) estimates by assuming proportional product length width. (MKSE)...
Stomata are involved in transpiration and CO2 uptake by mediating gas exchange between internal plant tissues the atmosphere. The capacity for depends on stomatal density (SD), size, pore dimensions. Most published work quantification has assumed that distribution spatially homogeneous across leaf, but this assumption been seldom tested. We selected 32 leaves from a Photinia hybrid, × fraseri ‘Red Robin’, one of its parents, P. serratifolia. For each leaf surface was divided into three or...
In nature, the fruit shapes of many plants resemble avian eggs, a form extensively studied as solids revolution. Despite this, hypothesis that egg-shaped fruits are themselves revolution remains unvalidated. To address 751 Cucumis melo L. var. agrestis Naud. were photographed, and two-dimensional (2D) boundary coordinates each profile digitized. Then, explicit Preston equation (EPE), universal egg-shape model, was used to fit 2D obtain estimates EPE's parameters fruit. Under revolution,...
Abstract Cotyledons play an important role in early seedling establishment. However, relative to primary leaves, cotyledons tend have a different investment-on-return strategy. To detect the potential differences mass (M) versus area (A) scaling relationships between and leaves light environments, total of 75 Acer platanoides seedlings were sampled at open site (n = 52; availability: 74 ± 5 %) shaded 23; 4.2 1.2 %). Reduced major axis regression protocols used fit M A cotyledons. The...
Total leaf area per shoot (AT) can reflect the photosynthetic capacity of a shoot. A prior study hypothesized that AT is proportional to product sum individual widths (LKS) and maximum length (WKS), referred as Montgomery–Koyama–Smith equation (MKSE). However, empirical evidence does not support such relationship hypothesis, was found allometrically scale with LKSWKS, i.e., AT∝LKSWKSα, where α≠1, power law (PLE). Given there variation in total number leaves (n), little known about whether...
