Bud in the context of "Pruning"

In plant morphology, a cataphyll (sometimes also called a cataphyllum or cataphyll leaf) is a reduced, small leaf. Many plants have both "true leaves" (euphylls), which perform most of the photosynthesis, and cataphylls, which are modified to perform other functions.

Cataphylls include bracts, bracteoles and bud scales, as well as any small leaves that resemble scales, known as scale leaves. The functions of cataphylls, such as bud scales, may be short-lived, and they are often shed after their function is fulfilled.

The artichoke (Cynara cardunculus var. scolymus), also known by the other names: French artichoke, globe artichoke, and green artichoke in the United States, is a variety of a species of thistle cultivated as food.

The edible portion of the plant consists of the flower buds before the flowers come into bloom. The budding artichoke flower-head is a cluster of many budding small flowers (an inflorescence), together with many bracts, on an edible base. Once the buds bloom, the structure changes to a coarse, barely edible form. Another variety of the same species is the cardoon, a perennial plant native to the Mediterranean region. Both wild forms and cultivated varieties (cultivars) exist.

Cloves are the aromatic flower buds of a tree in the family Myrtaceae, Syzygium aromaticum (/sɪˈzɪdʒiːəm ˌærəˈmætɪkəm/). They are native to the Maluku Islands, or Moluccas, in Indonesia, and are commonly used as a spice, flavoring, or fragrance in consumer products, such as toothpaste, soaps, or cosmetics. Cloves are available throughout the year owing to different harvest seasons across various countries.

Spruce beer is a beverage flavored with the buds, needles, or essence of spruce trees. Spruce beer can refer to either alcoholic or non-alcoholic beverages.

A number of flavors are associated with spruce-flavored beverages, ranging from floral, citrus, and fruity, to cola-like flavors to resinous and piney. This diversity in flavor likely comes from the choice of spruce species, the season in which the spruce ingredients are harvested, and the manner of preparation.

A lignotuber is a woody swelling of the root crown possessed by some plants as a protection against destruction of the plant stem, such as by fire. Other woody plants may develop basal burls as a similar survival strategy, often as a response to coppicing or other environmental stressors. However, lignotubers are specifically part of the normal course of development of the plants that possess them, and often develop early on in growth. The crown contains buds from which new stems may sprout, as well as stores of starch that can support a period of growth in the absence of photosynthesis. The term "lignotuber" was coined in 1924 by Australian botanist Leslie R. Kerr.

Plants possessing lignotubers include many species in Australia; Eucalyptus marginata (jarrah), Eucalyptus brevifolia (snappy gum) and Eucalyptus ficifolia (scarlet gum) all of which can have lignotubers 3 m (10 ft) wide and 1 m (3 ft) deep, as well as most mallees (where it is also known as a mallee root) and many Banksia species.

Underground stems are modified plant parts that derive from stem tissue but exist under the soil surface. They function as storage tissues for food and nutrients, facilitate the propagation of new clones, and aid in perennation (survival from one growing season to the next). Types of underground stems include bulbs, corms, rhizomes, stolons, and tubers.

Plants have two structures or axes of growth, which can be best seen from seed germination and growth. Seedlings develop two axes of growth: stems, which develop upward out of the soil, and roots, which develop downward. The roots are modified to have root hairs and branch indiscriminately with cells that take in water and nutrients, while the stems are modified to move water and nutrients to and from the leaves and flowers. Stems have nodes with buds where leaves and flowers arise at specific locations, while roots do not. Plants use underground stems to multiply by asexual reproduction and to survive from one year to the next, usually through dormancy. Some plants produce stems modified to store energy and preserve a location of potential growth to survive a cold or dry period which normally is a period of inactive growth, and when that period is over the plants resume new growth from the underground stems.

Sprouting is the natural process by which seeds or spores germinate and put out shoots, and already established plants produce new leaves or buds, or other structures experience further growth.

In the field of nutrition, the term signifies the practice of germinating seeds (for example, mung beans or sunflower seeds) to be eaten raw or cooked, which is considered more nutritious.

In agricultural sciences, thinning is the removal of some plants, or parts of plants, to make room for the growth of others. Selective removal of parts of a plant such as branches, buds, or roots is typically known as pruning.

In forestry, thinning is the selective removal of trees, primarily undertaken to improve the growth rate or health of the remaining trees. Overcrowded trees are under competitive stress from their neighbors. Thinning may be done to increase the resistance of the stand to environmental stress such as drought, insect infestation, extreme temperature, or wildfire.
