Genetic Architecture of Leaf Ecophysiological Traits in Helianthus [PDF]

Journal of Heredity, 2007
We investigated quantitative trait loci (QTLs) for several leaf chemistry traits in early-generation hybrids between Helianthus annuus and Helianthus petiolaris, the parental species of the ancient diploid hybrid sunflower species Helianthus anomalus, Helianthus deserticola, and Helianthus paradoxus. We grew individuals of a second-generation backcross

Decline of Leaf Hydraulic Conductance with Dehydration: Relationship to Leaf Size and Venation Architecture     [PDF]

Plant Physiology, 2011
Abstract Across plant species, leaves vary enormously in their size and their venation architecture, of which one major function is to replace water lost to transpiration. The leaf hydraulic conductance (K  leaf) represents the capacity of the transport system to deliver water, allowing stomata to remain open for photosynthesis ...

Descrição do padrão de venação foliar em Spathicarpa Hook. (Araceae) Description of leaf venation pattern in Spathicarpa Hook. (Araceae)

Acta Botânica Brasílica, 2007
O estudo e a caracterização da venação foliar representam uma possibilidade de auxílio no reconhecimento de grupos taxonômicos identificados, predominantemente, com base em caracteres reprodutivos como o gênero Spathicarpa Hook. (Araceae).

An image dataset of cleared, x-rayed, and fossil leaves vetted to plant family for human and machine learning [PDF]

PhytoKeys, 2021
Leaves are the most abundant and visible plant organ, both in the modern world and the fossil record. Identifying foliage to the correct plant family based on leaf architecture is a fundamental botanical skill that is also critical for isolated fossil ...

Architecture Based Classification of Leaf Images

CoRR, 2018
Plant classification and identification has so far been an important and difficult task. In this paper, an efficient and systematic approach for extracting the leaf architecture characters from captured digital images is proposed. The input image is first pre-processed in five steps to be prepared for feature extraction.

Refining the genetic architecture of flag leaf glaucousness in wheat [PDF]

Theoretical and Applied Genetics, 2020
AbstractKey messageThe cuticle is the plant’s barrier against abiotic and biotic stresses, and the deposition of epicuticular wax crystals results in the scattering of light, an effect termed glaucousness. Here, we dissect the genetic architecture of flag leaf glaucousness in wheat toward a future targeted design of the cuticle.AbstractThe cuticle ...

Contributions of leaf distribution and leaf functions to photosynthesis and water-use efficiency from leaf to canopy in apple: A comparison of interstocks and cultivars

Frontiers in Plant Science, 2023
Grafting has been widely used in horticulture to induce dwarfing and avoid stress-derived limitations on plant growth and yield by affecting plant architecture and leaf functions.

Leaf architecture, lignification, and tensile strength during vegetative phase change in Zea mays

Acta Societatis Botanicorum Poloniae, 2011
Background and Aims: Leaf morphology, anatomy, degree of lignification, and tensile strength were studied during vegetative phase change in an inbred line of Zea mays (OH43 x W23) to determine factors that influence mechanical properties during ...

Artificial Neural Network Performance on Pakcoy Leaf Fresh Weight Model

Jurnal Ilmu Dasar, 2022
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
