Effect of perforated foil and polypropylene fibre covers on assimilation leaf area of early potato cultivars

open access: yesPlant, Soil and Environment, 2007
This paper presents the results of a three-year research on the effect of perforated polyethylene foil and polypropylene fibre covering at various lengths of plant cover period (2 and 3 weeks after plant emergence) on the assimilation leaf area of early ...

Allometric Relations in Leaves of Erythroxylum pauferrense: Endemic Species of Alto-Montana Forest in the Northeast Region, Brazil

open access: yesFloresta e Ambiente, 2020
Studies of leaf surface are important for the ecophysiological context. We tested 12 allometric equations to estimate the leaf area of the endemic species Erythroxylum pauferrense Plowman, using different morphometric measurements (n = 600). The analysis

Assessments of CO2 Assimilation on a Per-leaf-area Basis are Related to Total Leaf Area [PDF]

open access: yesJournal of the American Society for Horticultural Science, 2007
Net photosynthetic rates often are dependent on leaf size when expressed on a leaf-area basis (CO 2 assimilation as μmol·m −2 ·s −1 ).

Is an Apple an Orange? A Large Language Model Benchmark for Candidate Term Extraction and Subclass Decisions Against Upper Ontologies in Engineering and Materials Science

open access: yesAdvanced Engineering Materials, EarlyView.
Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Influence of the amount of water on the growth of one species and four hybrids of Paulownia in the first year of cultivation in Central Europe

open access: yesJournal of Forest Science
A lack or, conversely, an excess of water during the first growing seasons can bring about a slowdown in the growth of plants, their stagnation or even death. The necessary amount of water is not known for most hybrids of Paulownia.
