The Genotype of the Endosperm and Embryo as It Influences Vivipary in Maize [PDF]

open access: yes, 1952
The development of the maize seed is dependent on the orderly unfolding of events in which each component of the developing caryopsis has a particular role to play.

Effect of Attractants and Micronutrient Biofortification on the Yield and Quality of Red Clover (Trifolium pratense L.) Seeds

open access: yesAgronomy, 2021
The aim of the research was to develop an innovative technique in the seed production of red clover. The research was carried out in 2013–2016, in Felin (51°22′ N, 22°65′ E), in a dependent arrangement (split-split-plot) in four replications.

Germination capacity of some halophytic plants species under increasing salinity [PDF]

open access: yesAfrican Journal of Agricultural Research, 2016
In Tunisia, more particularly in semiarid and arid areas, the drought accentuated by the surface evaporation of water lead to gradual increase in salinity of the soil which a major hurdal in development of vegetation. In these highly salted ecosystems, some plants are growing naturally; however, various species show different tolerance levels to ...

Storage behavior and improving seed and seedling quality of the endangered tree species, Agathis borneensis Warb., using biopriming treatments

open access: yesForest Science and Technology
Agathis borneensis Warb. propagation, an endangered tree species with high conservation and economic value, is often hampered by a rapid decline in seed quality.

Impact of pre-sowing treatment and sowing season on Douglas fir emergence rate in a specific seed lot

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2013
Not only in the Czech Republic there is a problem with low yield of Douglas fir seedlings in forest tree nurseries. It can be caused mainly by two factors: the type of pre-sowing treatment and the temperature at the time of sowing.

Can species richness be maintained in logged endemic Acacia Heterophylla forests (Reunion Island, Indian Ocean) ? [PDF]

open access: yes, 2007
It is assumed that forests can serve multiple uses, including wood production and maintenance of high biodiversity level. We tested this hypothesis by studying eradication methods of invasive plants currently implemented in exploited endemic Acacia ...

Effect of Plant Growth-Promoting Rhizobacteria on Salicornia ramosissima Seed Germination under Salinity, CO2 and Temperature Stress [PDF]

open access: yes, 2019
In a scenario of climate change and growing population, halophyte root microbiota interactions may be a sustainable solution to improve alternative crop production while combating abiotic stress.

A Vascular Microphysiological Model of Lung Fibrosis Reveals That Myofibroblasts and IPF Patient‐Derived Fibroblasts Impair Angiogenesis and Vasculogenesis

open access: yesAdvanced Functional Materials, EarlyView.
A microphysiological lung fibrosis model recapitulates myofibroblast–vascular interactions. Induced myofibroblasts and patient‐derived IPF fibroblasts impair angiogenesis and increase vascular permeability via TGF‐β1–driven signaling. Pharmacological interventions with SB 431542 and VEGF supplementation restore vascular morphology and barrier function.

Improvement of seed germination of Fagus orientalis Lipsky [PDF]

open access: yes, 2003
This thesis was seeking two main approaches for improvement of seed germination of oriental beech, a timber producing species in Hyrcanian forests in northern Iran. Germination behavior of beechnuts was enhanced either by decreasing the dormancy breakage

Region‐to‐Region Unidirectional Connection In Vitro Brain Model for Studying Directional Propagation of Neuropathologies

open access: yesAdvanced Functional Materials, EarlyView.
A unidirectional cerebral organoid–organoid neural circuit is established using a microfluidic platform, enabling controlled directional propagation of electrical signals, neuroinflammatory cues, and neurodegenerative disease–related proteins between spatially separated organoids.
