Evolutionarily stable germination strategies with time-correlated yield
Theoretical Population Biology, 2006We investigate the effect of auto-correlated yield on the evolutionarily stable germination fraction of dormant seeds. By using both analytics and numerics, we first show that in a regime of small fluctuations a positive correlation reduces dormancy and a negative correlation enhances dormancy.

Hydrothermal time as a tool in comparative germination studies.
2009Hydrothermal time (HTT) analysis is an effective method for quantifying germination response to temperature and water potential. Time course curves under any temperature and water potential conditions can be generated from knowledge of the HTT parameters mean base water potential, standard deviation of base water potentials, base temperature, and ...

Light and Heavy Turfgrass Seeds Differ in Germination Percentage and Mean Germination Thermal Time
Crop Science, 2004Seed weight is often related to germination percentage (GP) and mean germination time (MGT) within seed lots, but the relationships are poorly described. In this study, we described these relationships in the species slender creeping red fescue (Festuca rubra L. subsp.

Magnetic-time model for seed germination
2016Germination of seed depends on several physico-chemical factors like temperature, water potential, light, nitrate content, smoke, electric field and magnetic field. In the present work, effect of static magnetic field on black-gram seeds (Cicer arietinum L.) was described. Seeds of C. arietinum L. were exposed in batches to static magnetic fields of 0

PRECONDITIONING OF GERMINATION IN LETTUCE AT TIME OF FRUIT RIPENING
American Journal of Botany, 1962Koller, D. (The Hebrew U., Jerusalem.) Preconditioning of germination in lettuce at time of fruit ripening. Amer. Jour. Bot. 49(8): 841–844. 1962.—The effects of controlled environments during maturation on subsequent germination response of the seed were investigated with the light‐sensitive lettuce ‘Grand Rapids.‘ The plants matured under a variety ...

Starch structure-property relations as a function of barley germination times
International Journal of Biological Macromolecules, 2019Two varieties of barley samples were subjected to germination conditions to investigate the underlying mechanisms underpinning changes in molecular structure, chemical compositions and thermal properties of starch during this process. Starch thermal transitions were examined using differential scanning calorimetry, and the molecular fine structure of ...

Seeds and seasons: interpreting germination timing in the field
Seed Science Research, 2005This paper discusses how field and laboratory experiments, using a variety of genetic material, can be combined to investigate the genetic basis of germination under realistic ecological conditions, and it reviews some of our recent work on germination phenology ofArabidopsis thalianain the field.

Constraints on the timing of seed germination in a tropical forest
1986A community study of seed germination in light-gap and shaded understory habitats indicated that the timing of germination differed significantly between the two habitats. The number of seedlings germinating in light-gaps was greater than that in the understory and the time of maximum germination was earlier in the rainy season.
