Predictive dormancy occurs when an organism enters a dormant phase before the onset of adverse conditions. For example, photoperiod and decreasing temperature are used by many plants to predict the onset of winter. Consequential dormancy occurs when organisms enter a dormant phase after adverse conditions have arisen. This is commonly found in ...
Latent buds – axillary buds whose development is inhibited, sometimes for many years, due to the influence of apical and other buds. Also known as dormant buds. Lateral buds – a bud located on the side of the stem, usually in a leaf axil. Late wood – the portion of the annual ring that is formed after the formation of earlywood has ceased.
The protective external layer of tissue on the stem s and root s of woody trees and shrubs; includes all of the living and non-living tissue external to the cambium. basal Situated or attached at or close to the base (of a plant or a phylogenetic tree diagram). basifixed Something attached by its base, e.g. an anther attached to the filament.
Understory reinitiation: Trees die from low-level mortality, such as windthrow and diseases. Individual canopy gaps start to appear and more light can reach the forest floor. Hence, shade-tolerant species can establish in the understory. Old-growth: Main canopy trees become older and more of them die, creating even more gaps.
The definition of a specific vegetation type may include not only physiognomy but also floristic and habitat aspects. [15] [16] Furthermore, the phytosociological approach in the study of vegetation relies upon a fundamental unit, the plant association, which is defined upon flora. [17]
Dendrology (Ancient Greek: δένδρον, dendron, "tree"; and Ancient Greek: -λογία, -logia, science of or study of) or xylology (Ancient Greek: ξύλον, ksulon, "wood") is the science and study of woody plants (trees, shrubs, and lianas), specifically, their taxonomic classifications. [1]
Hardwoods are produced by angiosperm trees that reproduce by flowers, and have broad leaves. Many species are deciduous. [ 2 ] Those of temperate regions lose their leaves every autumn as temperatures fall and are dormant in the winter, but those of tropical regions may shed their leaves in response to seasonal or sporadic periods of drought.
In the fields of horticulture and botany, the term deciduous (/ d ɪ ˈ s ɪ dʒ u. ə s /) [1] [2] means "falling off at maturity" [3] and "tending to fall off", [4] in reference to trees and shrubs that seasonally shed leaves, usually in the autumn; to the shedding of petals, after flowering; and to the shedding of ripe fruit.
