It is composed of phanerophytes with leaf buds that are protected from drought by scales (cataphylls or hairs), having deciduous sclerophyllous or membranaceous adult leaves. The degree of deciduousness, i.e. leaf loss, is dependent on the intensity and duration of basically two reasons: minimum and maximum temperatures and water balance ...
Plant senescence is the process of aging in plants. Plants have both stress-induced and age-related developmental aging. [1] Chlorophyll degradation during leaf senescence reveals the carotenoids, such as anthocyanin and xanthophylls, which are the cause of autumn leaf color in deciduous trees.
Although "tree" is a common word, there is no universally recognised precise definition of what a tree is, either botanically or in common language. [ 1 ] [ 2 ] In its broadest sense, a tree is any plant with the general form of an elongated stem, or trunk, which supports the photosynthetic leaves or branches at some distance above the ground ...
Spring in temperate deciduous forests is a period of ground vegetation and seasonal herb growth, a process that starts early in the season before trees have regrown their leaves and when ample sunlight is available. Once a suitable temperature is reached in mid- to late spring, budding and flowering of tall deciduous trees also begins.
