QTL analysis of leaf architecture

Journal of Plant Research, 2009
Leaf size and shape define the photosynthetic capability of a plant and have a significant impact on important agronomic traits, such as yield, quality, disease resistance and stress responses. Cultivated varieties of many plant species show remarkable variations in leaf morphology.

Fractal analysis of leaf shapes

Canadian Journal of Forest Research, 1986
An application of fractal mathematics to the analysis of leaf shapes is presented. Six leaves randomly selected from nine tree species were used in the study. A video imaging method together with microcomputer-based image processing was used to generate leaf outlines.

Analysis of Circadian Leaf Movements

2016
The circadian clock is a molecular timekeeper that controls a wide variety of biological processes. In plants, clock outputs range from the molecular level, with rhythmic gene expression and metabolite content, to physiological processes such as stomatal conductance or leaf movements.

An automatic leaf analysis system

2013 IEEE International Symposium on Consumer Electronics (ISCE), 2013
In this paper, we proposed an automatic vision-based leaf analysis system. The proposed system is composed of two units: image acquisition unit and image analysis unit. To evaluate the proposed scheme, several images containing different species of leaves are captured by using low-cost webcam.

Leaf analysis for plant recognition

2016 7th IEEE International Conference on Software Engineering and Service Science (ICSESS), 2016
Plants are essential resources for nature and people's lives. Plant recognition provides valuable information for plant research and development, and has great impact on environmental protection and exploration. This paper presents a leaf analysis system for plant identification, which consists of three main components.

Fatigue Analysis of Leaf Springs

2023
This study aims to design leaf springs, also known as scissor springs, with the help of SolidWorks 2018 program in computer environment and then analyze them with the help of Ansys Workbench 18.1 program in computer environment. In this study, we designed the parabolic leaf spring sample, which was actually produced (Type - 1), in a computer ...

Spectrochemical Analysis of Leaf and Biological Material

Analytical Chemistry, 1953
The role of hydrogen, carbon, nitrogen, oxygen, phosphorus, potassium, calcium, and magnesium as major nutrients, with iron as a secondary element of importance to plant life, has long been recognized. Recent studies have shown that the micro-nutrients, manganese, copper, boron, zinc, and in specific instances molybdenum, vanadium, and aluminum, play a

Analysis of leaf CO2 assimilation

1994
Canopy photosynthesis can be calculated by integrating individual leaf photosynthesis over the entire leaf canopy. The value of leaf photosynthesis at each point in time and each point in the leaf canopy is a function of the local environmental conditions, operating on the leaf response curve. Here, some characteristics of the leaf response curve shall

Genetic Analysis Of Leaf Development

1991
Abstract Plant development and the processes that control it have interested botanists for centuries. The traditional techniques of histology and plant morphology have been used for many years to generate a large body of knowledge on the generation of plant form.

Leaf Contamination by Atmospheric Pollutants as Assessed by Elemental Analysis of Leaf Tissue, Leaf Surface Deposit and Soil

Journal of Plant Physiology, 1996
In order to evaluate the influence of air pollutants influx on leaf elemental composition, the concentration of N, S, Cu, Fe and Pb were analyzed in the surface deposit and tissue of Quercus ilex L. leaves from 8 sites of the urban area of Naples. The soil from the trunk base area of Q.
