Key Metabolite Differences Between Korean Pine (Pinus koraiensis) Seeds With Primary Physiological Dormancy and No-Dormancy [PDF]
Frontiers in Plant Science, 2021 Pinus Koraiensis seeds have physiological dormancy. Cold stratification releases seed dormancy. The changes in metabolite profiles of dormant seeds and cold stratified seeds during shorter incubation time in a favorable condition for seed germination ...

Physiological quality and dormancy of rice seeds during storage
Revista Ciência Agronômica, 2021 Storage is a set of techniques adopted during the off-season, aiming at conditioning the seeds to maintain their quality for the next harvest. The study of effect by storage is important to know the performance of dormancy under different environments ...

Effect of Seed Position on Parental Plant on Proportion of Seeds Produced with Nondeep and Intermediate Physiological Dormancy. [PDF]
Front Plant Sci, 2017 The position in which seeds develop on the parental plant can have an effect on dormancy-break and germination. We tested the hypothesis that the proportion of seeds with intermediate physiological dormancy (PD) produced in the proximal position on a ...

Mechanisms of heat shock-induced germination in Suaeda glauca (Bunge) bunge: insights from endogenous hormonal regulation [PDF]
BMC Plant BiologyBackground Fire cues, such as heat and smoke, play crucial roles in seed germination, particularly in fire-prone ecosystems. A key challenge in understanding how fire cues affect the germination process is characterizing the complex and varied ...

Combined transcriptomic and metabolomic analysis of the molecular mechanism of seed dormancy release in Notopterygium incisum [PDF]
BMC GenomicsBackground Notopterygium incisum seeds have both morphological and physiological dormancy characteristics and require stratification to break seed dormancy, but the mechanism of seed dormancy release during stratification is still unclear. In this study,
