A Hydrothermal After-ripening Time Model of Seed Dormancy Loss in Bromus tectorum
<p>After-ripening, the process of seed dormancy loss in dry storage is associated with a decrease in the mean base water potential, one of the parameters of hydrothermal time. The rate of change of the mean base water potential is assumed to be a linear function of temperature above a specific base …

Studies on the Plasticity of Dormancy and on Aging in Switchgrass Seeds
… be broken by a variety of treatments, including after-ripening and stratification. This study was conducted to investigate and characterize more systematically factors affecting both after-ripening and stratification effectiveness, and the aging that can occur concomitantly with after-ripening. …

Wild lettuce as a source of natural rubber
… were found to have the power of germinating soon after ripening. Seeds ripened in the fall were found to have between 49 and 68 percent germinating power.

Evaluation of alpha-amylase activity and falling number for soft white and soft red wheat varieties adapted to Michigan
… both responses at PM in all misting treatments. After-ripening period had a significant effect on breaking dormancy for some lines, and an effective protocol for PHS screening at MSU was identified. `Jupiter', `Lowell' and `Caledonia' were highly susceptible, while `MSU E5024' and AgriPro `W1062' …

WET PROCESSING OF FIBRE BLENDS CONTAINING PRE HARVEST RETTED FLAX
… two weeks alter mid-point of flowering and (b) after ripening of the seeds. Infra red analysis of extracted lignin led to the suggestion that a lower lignin content in the middle lamella of early-desiccated crops permits retting to proceed further, to give smaller (finer) bundles of fibres after …

Development of native species of Crete in the urban landscape: an investigation of systems and plant reproduction, adaptability and fitness of wild species in commercial horticulture
… species, Other factors were important including after-ripening for P. chamaepence and S. petiolata, scarification for P. majus and C. dorycnium and imbibition in 20°C for C macrophyllum and S. sicula. Propagation by stem cuttings was influenced by mist, addition of IBA, the season and the …

Seed dormancy and germination niches of Mediterranean species along an altitudinal gradient in Sardinia
… (cold and warm stratification and dry after ripening) and hormones (gibberellins) on the thermal requirements for seed dormancy release and germination of the target taxa was assessed. To study and monitor the annual trend of local soil temperatures, close to the study species, 24 …

Effect of lauric acid and monolaurin on the multiplication of Listeria monocytogenes and Listeria innocua at 10°C in bi-phasic systems.
… of the cheese were less at 10[5] cfu g[-1] after ripening for 28 d at 10 °C. Addition of 0.9 mM monolaurin reduced the count to 10[5] cfu g[-1] after 28 d ripening at 10 °C on the surface of the cheese. The effect of increasing the initial draining time at ambient temperature from 24 …

Seed ecophysiology and plant population ecology of Cynoglossum officinale L. and Tragopogon spp.
… dormancy could be released by stratification and after-ripening in T. pratensis, but not by light. Seeds germinated over a range of temperatures with 15 C as the optimumin both weeds. A seed burial study showed that increased seeding depth had no effect on seed germination, but reduced seedling …

Influence of probiotic organisms on proteolytic pattern, release of bioactive compounds and sensory attributes of cheddar cheese
… viability at > 7.5 log10 cfu g-1 at the end of ripening at 4oC for 24 wk. The counts of lactococci in the cheeses decreased by one to two logs at the end of ripening, but counts were not significantly different (P > 0.05) between the control and probiotic cheeses. Addition of probiotic organisms …

Seed germination requirements and salt stress tolerance of coastal rare species in Sardinia
To survive to adverse factors that characterize coastal environments, plant species often require special physiological or metabolic adaptations to overcome environmental stresses. Stress may be physical (e.g. temperature) or chemical (e.g. salinity). Many communities comprise highly specialized …
