متن کاملPrior hydration of Brassica tournefortii seeds reduces the stimulatory effect of karrikinolide on germination and increases seed sensitivity to abscisic acid.
BACKGROUND AND AIMS The smoke-derived compound karrikinolide (KAR(1)) shows significant potential as a trigger for the synchronous germination of seeds in a variety of plant-management contexts, from weed seeds in paddocks, to native seeds when restoring degraded lands. Understanding how KAR(1) interacts with seed physiology is a necessary precursor to the development of the compound as an effi...
متن کاملSeeds of Brassicaceae weeds have an inherent or inducible response to the germination stimulant karrikinolide.
BACKGROUND AND AIMS Karrikinolide (KAR(1)) is a smoke-derived chemical that can trigger seeds to germinate. A potential application for KAR(1) is for synchronizing the germination of weed seeds, thereby enhancing the efficiency of weed control efforts. Yet not all species germinate readily with KAR(1), and it is not known whether seemingly non-responsive species can be induced to respond. Here ...
متن کاملDormancy and germination response of Galbanum seeds (Ferula gummosa) under different hormonal pre-treatments and cold stratification
Extended Abstract Introduction: Galbanum is one of the most important native medicinal plants in Iran, and nowadays the use of its products and derivatives has become widespread in various industries. Thus, the excessive harvest of this species within its natural habitats has increased. Therefore, the species is enlisted as prone to extinction. Due to the lack of information about germination ...
متن کاملThe effect of climate on water content, dormancy and dehydrins expression pattern in pistachio seeds
The environmental conditions which the parent plant has undergone during seed development can affect many properties of the seeds such as degree of dormancy, weight and the amount of their compounds. In this study, mature pistachio seeds of Ahmadaghaei cultivar, collected from the two cities of Rafsanjan and Shahrbabak located in Kerman Province (Iran), were compared. It was found that the seed...
