Steps Toward the Natural System of the Dicotyledons [PDF]

open access: yes, 1989
The value of vegetative anatomy in phylogenetic analysis is documented. Examples of the use of vegetative anatomy at different taxonomic levels show the continuing role of the anatomical method in building a more natural system of classification of the ...

Induced Systemic Resistance (ISR) and Fe Deficiency Responses in Dicot Plants

open access: yesFrontiers in Plant Science, 2019
Plants develop responses to abiotic stresses, like Fe deficiency. Similarly, plants also develop responses to cope with biotic stresses provoked by biological agents, like pathogens and insects. Some of these responses are limited to the infested damaged

Ultrasonic Measurements In Brazilian Hardwood

open access: yesMaterials Research, 2002
This paper reports on a study of the application of ultrasound waves in wood with the purpose of evaluating the latter's mechanical properties. The evaluation is based on the correlation between the speed of sound, modulus of elasticity and density.

Moderately inhibitory effects of N-dodecyloxymethylene-N-methylpiperidinium and N-dodecyloxymethylene-N-methylmorpholinium chlorides on seed germination

open access: yesActa Societatis Botanicorum Poloniae, 2014
N-Dodecyloxymethylene-N-methylpiperidinium chloride (DMMP) and N-dodecyloxyme-thylene-N-methylmorpholinium chloride (DMMM) retarded germination of seeds of 9 cultivated plant species when applied at a concentration of 10-3 M, and inhibited germination at

Phylogenetic analysis and expression profiles of jasmonate ZIM-domain gene family provide insight into abiotic stress resistance in sunflower

open access: yesFrontiers in Plant Science, 2022
Jasmonate ZIM-domain (JAZ) proteins act as inhibitory factors of the jasmonic acid (JA) pathway, which is involved in regulating plant development and defense responses.

Marine Anoxia and Ocean Acidification During the End‐Permian Extinction

open access: yesGeophysical Monograph Series, Page 325-340., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

The influence of cut Festuca rubra L. turf not removed from the lawn surface on the proportion of dicotyledons in the lawn

open access: yesActa Agrobotanica, 2012
The aim of the study was to assess how the proportion of dicotyledons in the lawn was influenced by aboveground biomass containing Festuca rubra, cv. ‘Areta’, ‘Nimba’, and ‘Olivia’, cut and left on the lawn surface.

Selection of Grids for Weed Mapping [PDF]

open access: yesPlanta Daninha, 2015
This study aimed to assess the degree of similarity presented by thematic maps generated by different sampling grids of weed plants in a commercial agricultural area of 7.95 hectares. Monocotyledons and dicotyledons were counted on the 2012/2013 and 2013/

Distribution and Evolution of Forms and Types of Sieve-element Plastids in the Dicotyledons [PDF]

open access: yes, 1991
Sieve-element plastids may contain any combination of protein crystals (c), protein filaments (f), and starch grains (s), or none of these. All structurally distinct combinations (=forms) possible (s, cs, cfs, c, cf, fs, f, o) are recorded among the 2100
