The metagenomics of soil bacteria and fungi and the release of mechanical dormancy in hard seeds [PDF]

Frontiers in Plant Science, 2023
Persistence in the soil is a function of seed physiology, particularly non-germination and inherent lifespan. However, for seeds with mechanical dormancy, non-germination is also a function of the composition and activity of the soil microbiota.

Hard Seed Characteristics and Seed Vigor of Ormosia hosiei

Agriculture, 2023
The Ormosia hosiei is a secondary protected wild plant in China, and its seed has a hardness rate of 86%. To explore the characteristics of the hard seed and the difference in seed vigor between hard seeds and the non-hard seeds of O.

Multiple omics datasets reveal significant physical and physiological dormancy in alfalfa hard seeds identified by multispectral imaging analysis

Crop Journal, 2023
Physical dormancy (PY) commonly present in the seeds of higher plants is believed to be responsible for the germination failure by impermeable seed coat in hard seeds of legume species, instead of physiological dormancy (PD).

Germination control by a hard seed coat: insights from a tropical legume [PDF]

Scientific Reports
Classifying seed dormancy is an essential task for plant propagation; however, several plant species lack information about the kind of dormancy the seeds have or inaccurate reports are passed on without an in-depth investigation.

Can Seed Hardness Be an Ecological Filter in Seed Dispersal by Rodents?

Diversity
Seed hardness has been acknowledged as one of the most significant physical traits influencing seed consumption and caching by animals. From an evolutionary perspective, a hard seed shell should potentially be regarded as a dispersal and predator escape ...

Development of new methods for increasing the germination of licorice (Glycyrrhiza uralensis Fisch.) seeds: preliminary data [PDF]

E3S Web of Conferences, 2020
The licorice (Glycyrrhiza uralensis Fisch.) is cultivated as a valuable medicinal plant. It is grown from seeds, but 70-90% of its seeds are in deep physical dormancy (hard seeds) – do not swell and do not germinate without special treatment ...

Hardness of Optimal Spaced Seed Design [PDF]

Journal of Computer and System Sciences, 2005
Speeding up approximate pattern matching is a line of research in stringology since the 80s. Practically fast approaches belong to the class of filtration algorithms, in which text regions dissimilar to the pattern are first excluded, and the remaining regions are then compared to the pattern by dynamic programming.

Germination of the invasive legume Lupinus polyphyllus depends on cutting date and seed morphology [PDF]

NeoBiota, 2020
In semi-natural grasslands, mowing leads to the dispersal of species that have viable seeds at the right time. For invasive plant species in grasslands, dispersal by mowing should be avoided, and information on the effect of cutting date on the ...

Ensiling Reduces Seed Viability: Implications for Weed Management

Frontiers in Agronomy, 2021
Ensiling, a lactic acid fermentation process, is mainly used to preserve biomass. In addition, it has been shown to affect seed viability of some plant species.

Possibilities for improving the quality of alfalfa seed by applying temperature treatments before sowing [PDF]

Journal on Processing and Energy in Agriculture, 2018
In addition to normal seeds, hard seeds of alfalfa have often been found after harvest. Such seeds prevent the penetration of water and gases into the seed interior, causing the reduction in germination.
