The Concepts of Seed Germination Rate and Germinability: A Re-Evaluation for Cool-Season Grasses

open access: yesAgronomy, 2022
Temperature is one the most influential environmental factors for the germination and establishment of grass species. The specific objective of this study was to determine the effects of low constant temperature on the time needed to express the full germination capacity of nondormant seedlots. Fifteen accessions, comprising seven of Lolium perenne L.,

Enhancement of Germination Rate of Aged Seeds by Ethylene [PDF]

open access: yesPlant Physiology, 1971
Naturally and artificially aged seeds of rape, Brassica napus L., produced less ethylene than freshly harvested seed during the early stage of germination. With freshly harvested seeds one peak of ethylene production was observed during germination, which coincided with the emergence and elongation of root and cotyledon, accompanied by splitting of the

Germination Protein Levels and Rates of Germination of Spores of Bacillus subtilis with Overexpressed or Deleted Genes Encoding Germination Proteins [PDF]

open access: yesJournal of Bacteriology, 2012
ABSTRACT Deletion of Bacillus subtilis spores' GerA germinant receptor (GR) had no effect on spore germination via the GerB plus GerK GRs, and loss of GerB plus GerK did not affect germination via GerA. Loss of one or two GRs also did not affect levels of GRs that were not deleted. Overexpression of GRs 5-

Mesocotyl elongation in Digitaria sanguinalis during seedling development [PDF]

open access: yes, 2016
The mesocotyl is an embryonic organ present in Poaceae that plays an important role in seedling emergence. The elongation of this first internode contributes decisively to the coleoptile reaching the soil surface.

A Water Relations Analysis of Seed Germination Rates [PDF]

open access: yesPlant Physiology, 1990
Seed germination culminates in the initiation of embryo growth and the resumption of water uptake after imbibition. Previous applications of cell growth models to describe seed germination have focused on the inhibition of radicle growth rates at reduced water potential (Psi).

Germination Rate and Emergence Success in Bluebunch Wheatgrass [PDF]

open access: yesJournal of Range Management, 1994
Development of plant materials adapted to the demands of a harsh environment and conditions created by standard planting practices has resulted in improved seedling establishment for some species. Bluebunch wheatgrass (Pseudoroegneria spicata [Pursh] Love) is an important native bunchgrass often planted in the Intermountain and Pacific Northwest ...

Use of ultrasonication to increase germination rates of Arabidopsis seeds [PDF]

open access: yesPlant Methods, 2017
Arabidopsis thaliana is widely used as model organism in plant biology. Although not of agronomic significance, it offers important advantages for basic research in genetics and molecular biology including the availability of a large number of mutants and genetically modified lines.

Stratification requirements for seed dormancy alleviation in a wetland weed. [PDF]

open access: yes, 2013
Echinochloaoryzicola(syn.E. phyllopogon) is an exotic weed of California rice paddies that has evolved resistance to multiple herbicides. Elimination of seedlingsthroughcertain weed control methods can limit the spread of this weed, but is contingent on ...
