Seed dormancy prevents an intact, viable seed from successfully germinating under ideal circumstances. In order for germination to occur when conditions are likely be favourable forming a new plant generation, this barrier has developed differently among species through adaptation the local environment. Although there is still gap between biochemistry and morphogenesis, it being bridged in many...

Seeds are a vital component of the world’s diet. Cereal grains alone, which comprise -90% of all cultivated seeds, contribute up to half of the global per capita energy intake. Not surprisingly then, seed biology is one of the most extensively researched areas in plant physiology. Even in relation to the topics reviewed here, a casual perusal of the Agricola database reveals that well over 5000...

Annual growth cycles of perennial horticultural and forest woody plant species temperate boreal regions can be divided into two phases, namely the dormancy phases. During phase, vegetative reproductive meristems undergo to withstand subzero winter temperatures. The dormant state organs defined classically as a non-growing latent state, where no visible occurs in meristem containing plants struc...

In order to find the most effective method to overcome seed dormancy in Teucrium chamaedrys  L. medicinal plant species the effect of some chemical and physical breaking methods including: cold stratification (5 °C), scarification with sandpaper, stratification with needle, concentrated sulfuric acid, gibberellic acid and combination of these methods were investigated. Treated seeds along with ...

Many weeds produce dormant seeds that are unable to complete germination under favourable conditions. There two types of seed dormancy: primary dormancy (innate dormancy), in which a state upon release from the parent plant, and secondary (induced develops through some experience after plant. Mechanisms categorized as embryo coat-imposed dormancy. In dormancy, control resides within itself, it ...

Background: Bulbs of the ornamental flower Lilium pumilum enter a period of dormancy after flowering in spring, and require exposure to cold for a period of time in order to release dormancy. Previous studies focused mainly on anatomical, physiological and biochemical changes during dormancy release. There are no dormancy studies of the northern cold-hardy wild species of Lilium at the molecula...
