Estimating individual leaf area of potato from leaf length

The Journal of Agricultural Science, 1989
Measurements of the area of individual leaves in crops are useful in the analysis of canopy architecture as they allow determination of the structure of leaf area index in a vertical profile. This information may be of use in modelling leaf growth and the assessment of photosynthetic potential of different strata of the canopy with ontogeny (cf. Firman

Tree topology inference from leaf-to-leaf path lengths using Prüfer sequence

International Journal of Communication Networks and Distributed Systems, 2014
In this paper, we propose an algorithm to reconstruct the set of nodes and their topology relationships, particularly in case of a topological tree where all edge weights are 1, given the set of terminal vertices or leaves and their pairwise distances or path lengths.

Theory for Leaf Segment Lengths for Plant Canopies

Agronomy Journal, 1992
AbstractLeaves are considered the most important architectural components when studying the interaction of solar radiation with vegetation canopies. Models used in the study of solar radiation interaction with canopies generally assume randomly distributed leaves, with little or no attention to the arrangement of leaves and inter‐leaf gaps.

Length Measurement of Potato Leaf Using Depth Camera

IFAC-PapersOnLine, 2018
Abstract Leaf length is one of important parameters for crop growth estimation. In order to accurately obtain the plant leaf length, this paper proposes a slope linear hypothesis in which the leaf length could be measured in 3-D space with a right-angle model. A binocular stereo vision system was applied with RGB and depth image output.

Exploration of Genetic Selection in Rice Leaf Length and Width

Botany, 2018
Leaf length and width are two of the most important components of rice (Oryza sativa L.) plant architecture and directly contribute to yield. The genetic effects of leaf length and width are controlled by quantitative trait loci (QTLs). In this study, a double haploid (DH) population derived from a cross of O. sativa subsp. japonica cultivar ‘Maybelle’

A leaf sequencing algorithm to enlarge treatment field length in IMRT

Medical Physics, 2002
With MLC‐based IMRT, the maximum usable field size is often smaller than the maximum field size for conventional treatments. This is due to the constraints of the overtravel distances of MLC leaves and/or jaws. Using a new leaf sequencing algorithm, the usable IMRT field length (perpendicular to the MLC motion) can be mostly made equal to the full ...

Quantitative Trait Loci Mapping for Leaf Length and Leaf Width in Rice cv. IR64 Derived Lines

Journal of Integrative Plant Biology, 2010
Abstract The present study was conducted to identify quantitative trait loci (QTLs) for leaf size traits in IR64 introgression lines (INLs). For this purpose, selected F2 populations derived from crosses between recurrent parent IR64 and its derived INLs, unique for leaf length and leaf width, were used to confirm QTLs. A total of eight QTLs, mapped on

Modeling individual leaf area of ginger (Zingiber officinale Roscoe) using leaf length and width

Scientia Horticulturae, 2009
Abstract Leaf area estimation is an important biometrical observation one has to do for comparing plant growth in field and pot experiments. In this study, a leaf area estimation model was developed for ginger ( Zingiber officinale Roscoe), using linear measurements of leaf length ( L ) and maximum width ( W ).
