A bud is a growing point, surrounded by small, partially developed leaves. Its is in reality a rudimentary stem in a state of dormancy or limited growth, protected by an envelope of scales. It may consist of a mass of meristematic cells or of several nodes and very short internodes. Close examination of a well- developed bud reveals leaves and buds in the same order as on a growing stem of the same plant. Several classifications of buds origin, position on stem, position on node, time at which they begin growth, and function.

Position on Stem :
In the growth of buds are formed at different positions, The principal kinds of buds, with regard to their location on the stem, are terminal, auxiliary and lateral. Terminal buds are those that develop from the terminal growing point at the end of a stem when growth cusses. In some kinds of plants, they are formed regularly; in others the growing point tends to about, leaving no bud does form, it is usually the one to engine growth firsts the following spring. A terminal bud is regard as being dormant or largely so; whereas a terminal growing point is regarded as being in a state of active growth and elongation. An maxillary bud is one that occurs in the axil of a leaf- the angle between the leaf and the stem. They are designated as as axillary’s buds even after the leaf has shed. These buds are also properly calls lateral buds, however may occurs jor where the leaf was rudimentary. Examples of the latter class are frequently observed on parts of pecan shots that are formed near the end of the growing seasons. The peach, tung tree, and less frequently the rose produce shoots with certain nodes and leaf axils at which no buds occur, These are commonly blind buds or blind nodes.
