In a natural situation, seedling development starts with skotomorphogenesis while the seedling is growing through the soil and attempting to reach the light as fast as possible. During this phase, the cotyledons are tightly closed and form the apical hook to protect the shoot apical meristem from damage while pushing through the soil. In many ...
Seed dormancy is an evolutionary adaptation that prevents seeds from germinating during unsuitable ecological conditions that would typically lead to a low probability of seedling survival. [1] Dormant seeds do not germinate in a specified period of time under a combination of environmental factors that are normally conducive to the germination ...
Many plants and seeds recognize this and enter a dormant period in the fall to stop growing. The grain is a popular example in this aspect, where they would die above ground during the winter, so dormancy is favorable to its seedlings but extensive domestication and crossbreeding has removed most dormancy mechanisms that their ancestors had.

Germination is usually the growth of a plant contained within a seed resulting in the formation of the seedling.
Etiolation / iː t i ə ˈ l eɪ ʃ ən / is a process in flowering plants grown in partial or complete absence of light. [1] It is characterized by long, weak stems; smaller leaves due to longer internodes; and a pale yellow color . The development of seedlings in the dark is known as "skotomorphogenesis" and leads to etiolated seedlings.

Just because the growing season is coming to an end doesn’t mean that your work in the garden is through. Many plants, trees, and shrubs require pruning during different times of the year so ...
In reference to an inflorescence (a shoot specialised for bearing flowers, and bearing no leaves other than bracts), an indeterminate type (such as a raceme) is one in which the first flowers to develop and open are from the buds at the base, followed progressively by buds nearer to the growing tip. The growth of the shoot is not impeded by the ...
