The effect of smoke teatment on the germination on four species of Mesembryanthemum: some preliminary observations
… only one to be covered by a waxy cuticle. Seed dormancy was a feature of the species in which seed was improved by germination, whereas the seeds of the unresponsive species, R. macowanii and D. stokoei were non-dormant. Hence, smoke appears to act as a dormancy release cue, having no, or little …

Root growth potential and bud dormancy of three northern pines with emphasis on eastern white pine
… Potential (RGP) in a hydroponic system and Dormancy Release Index (DRI) in one-year-old (1-0) and two-year-old (2-0) eastern white pine (Pinus strobus L.), red pine (Pinus resinosa Ait.), and Scotch pine (Pinus sylvestris L.) seedlings with emphasis on eastern white pine. During 1985-86 all …

A novel system to study seed recalcitrance and dormancy - comparative proteomics between two Spartina species
… three aspects of S. alterniflora: recalcitrance, dormancy release by cold stratification and the effect of drying temperature on the critical water content. Comparative proteomics between S. alterniflora and orthodox, desiccation tolerant Spartina pectinata seeds identified 83 heat-stable (soluble …

Relationship between seed dormancy and persistence of seeds of annual ruderal species in the soil seedbank
… species. Although the relationship between seed dormancy and persistence in soil has received previous attention, it has not been well characterized. In order to quantify the relationship between seed persistence and dormancy, a five-year seedbank dynamics field study was conducted in Savoy, IL, …

Meccanismi fisiologico-molecolari di germinazione in specie spontanee
Seed dormancy provides a mechanism for plants to delay germination until conditions are optimal for survival of the next generation. Knowledge of dormancy release and dormancy induction requirements is important to increase our understanding about the entire process. Furthermore, to assess the …

Flowering Gene Homologs Regulate Seasonal Growth Changes in Poplar
… molecular mechanisms that regulate growth and dormancy transitions. Photoperiod and temperature regulate both vegetative and floral phenology. FLOWERING LOCUS T (FT) and FLOWERING LOCUS D (FD) are key regulators of flowering time in Arabidopsis and other plants. The distinct functions of three …

Unraveling Molecular Mechanisms Regulating Dormancy and Bloom Time in Apple (Malus × domestica Borkh)
Bud dormancy is an essential characteristic of deciduous woody perennials, including apple, to cope with the low temperatures during winter. The release from dormancy and subsequent budburst in apple can only occur after fulfillment of chilling and heat requirements. In the Mid-Atlantic region, …

Seed dormancy and germination niches of Mediterranean species along an altitudinal gradient in Sardinia
… it is also considered responsible for changes in dormancy states of seeds. Seed dormancy has probably evolved differently across species, through adaptation to various habitats and prevailing environments. Under a Mediterranean climate, characterised by a considerable unpredictability of …

Germination niche of Sardinian endemic species in mountain riparian deciduous forests
… soil and, also is responsible for changes in dormancy states of seeds. Seed dormancy prevents germination in a specified period of time, under any combination of environmental factors that otherwise favour germination and it is mediated, at least in part, by the plant hormones abscisic acid …

GENOMIC TOOLS TO IMPROVE PEACH (P. PERSICA L. BATSCH) RESILIENCE TO CLIMATE CHALLENGES
… to inadequate chill satisfaction and incomplete dormancy release. Dormancy is a finely regulated mechanism developed by temperate fruit trees to synchronize their vegetative and reproductive phenology with the cyclic availability of favourable temperature conditions in the growing environment. …
