dormancy

Woke up and fell asleep: "(He is resting on the sofa on the 邋 sofa, his mouth is open, and the glasses are soft on the swollen nostrils" (Steven Heighton)

2. It is not active at the moment, or the performance may be so. "Painful experience, ... is a dormant state but it is still threatening" (Charles Jackson). Synonyms are also not active

4. Biological dormancy or inactivation characterized by growth or development arrest, many metabolic processes are paused: dormant buds; dormant bacteria

Dormancy - quiet (but temporary) hibernation, "hibernating volcano erupts for centuries of dormancy" hibernation - especially during the summer months of deceleration or deceleration during the summer months of animals In activity, new activities decrease or activity slows down; especially in some animals, the metabolism of some animals slows down during hot or dry periods.

Many plant species that exhibit dormancy have a biological clock that slows activity during freezing or water shortage and indicates when to prepare soft tissue. On the other hand, you can cause dormancy after the normal growing season by lowering the temperature, shortening the length of the day, and / or reducing the amount of rain. Chemical treatment of dormant plants has proved to be an effective way to break dormancy in woody plants such as grapes, berries, apples, peaches and kiwis, among others. In particular, cyanamide stimulates cell division and growth of dormant plants and causes germination when plants are at the limit of breaking dormancy. Mild damage to cells may play a role in the mechanism of action. Damage is thought to result in increased permeability of the cell membrane. Damage is associated with inhibition of catalase, which in turn stimulates the pentose phosphate cycle

If mature viable seeds can not germinate under favorable conditions, it is said to be in a dormant state. Seed dormancy is known as embryonic dormancy or internal dormancy and is caused by the intrinsic characteristics of the embryos that prevent germination (Black M, Butler J, Hughes M. 1987). Dormancy should not be confused with seed coat dormancy, external dormancy or hard shell caused by hard seed covering and seed coat that prevents water and oxygen from reaching and activating the embryo. It is a physical barrier to germination and not a real form of dormancy (Quinliven, 1971; Quinliven and Nichol, 1971)

Morphologic physiological sleep includes seeds with undeveloped embryos and also has dormant physiological components. Therefore, these seeds require dormancy dormancy treatment and the development of well-grown embryos for a period of time. Plant families experiencing morphological and physiological dormancy include navel leaves, golden flower family, lily, magnolia, poppy and Ranunculaceaceae. Some plants in morphologically physiological dormancy like Asarum and Trillium have multiple types of dormancy state. One affects root (root) growth, and the other affects embryo (bud) growth. The terms "double dormancy" and "2 year seed" take two years to complete germination, or at least two winter and one summer species. Bud dormancy was broken in the second winter, but the bud dormancy was destroyed in the first winter after spraying.
