Bud

the original body of a branch that is in a young state. It is a bag of many different sizes of young leaves, very short between sections, as yet undeveloped branches. Buds germinate as branches when climate and other conditions are appropriate. According to the nature of the organs to be formed by buds, it can be divided into three types: (
1
) buds, also known as leaf buds, in the nutritional growth stage of plants, the development of branches (including stems and leaves) buds, the shape is relatively thin and long. (
2
) buds, when the plant is reproductive growth, some stems or leaves are divided into
tissues
split and differentiate to form the original body of buds, stretching can form flowers or flower-order buds, the shape is bigger than leaf buds. (
3
) mixed buds, some plant buds, forming both flowers and branches at the same time.According to the location of buds in the plant can be divided into top buds and buds: (
1
) top buds, located at the top of the plant's main stem or side branches, the shape is generally larger than other buds, and the most active growth, after development can make the stem up (backland) growth. (
2
) buds, also known as side buds. Born in the main stem and side branches and leaves, the shape is small, after development can form a secondary side branch, its growth and development is often inhibited by the top bud. The position where the top buds and buds occur on the stems is fixed and collectively referred to as the buds. The occurrence of location is not fixed, such as occurring between the stems, old stems and old roots, leaves and healing tissue buds, are called indeterminate buds. In production, plant materials such as roots, stems and leaves are often used to produce the properties of indeterminate buds for nutritional reproduction.
