TLDR
The initial water uptake rate was found to decrease as the external water poten tial decreased, due to reduced diffusivity to water of the seed coats, but the final water gained by imbibition was sufficient to ensure full germination.Abstract:
Water uptake patterns and germination rates of chickpea (Cicer arietinum L.) and vetch (Vicia faba L.), as affected by constant and changing external water potential, were studied experimentally. The initial water uptake rate was found to decrease as the external water poten tial decreased, due to reduced diffusivity to water of the seed coats, but the final water gained by imbibition was sufficient to ensure full germination. Germination rate decreased with a decrease in the external water potential. The data presented suggest that more work should be directed toward a better understanding of the effects of external water potential changes on the enzymatic activity during and after the imbibition stage.read more

Germination ecology of halophytes
TL;DR: Several studies have shown that seeds of many halophytes remain dormant when exposed to low water potentials, and seed germination in saline environments ordinarily occurs during the spring or in a season with high precipitation.

Water Stress Effects on Leaf Growth and Chlorophyll Content but Not the Grain Yield in Traditional Rice ( Oryza sativa Linn.) Genotypes of Assam, India II. Protein and Proline Status in Seedlings under PEG Induced Water Stress
TL;DR: The results indicated that plant height and seed number have significant genotypic coefficient of variability (GCV) and heritability and Verities like Laodubi, Leserihali, Beriabhanga and Borah were screened out as the best drought sustaining variety.

The germination of seeds
TL;DR: In his Friday evening discourse at the Royal Institution on November 3, Sir Arthur Hill discussed the many ingenious devices for the protection of the seed and equally ingenious arrangements for the escape of the embryo on germination, which are found in plants.

Physical aspects of soil water and salts in ecosystems
TL;DR: In this article, a model for the water and salt economy in frozen Soil Water Systems is presented, based on the D-6 function derived from Numerical Analysis. But, the model is not suitable for the case of water flow in fields.
