1. A form of asexual reproduction in which a new individual develops as an outgrowth of a mature organism. Yeast cells exhibit budding and sometimes the new cells so produced can themselves give rise to further buds before the chain of individuals separates. Compare fission, fragmentation.
2. (bud grafting) A type of *grafting
in which a bud (the scion) of the desired variety, together with a small piece of bark, is removed and inserted into a slit made in the bark of the chosen root-stock (the stock), and secured with raffia or tape. The rootstock is usually cut back and any buds removed. The technique is widely used to propagate rosebushes. Bush roses are produced by inserting buds as near to the ground as possible while standard roses are produced by inserting buds higher up on the stem of the rootstock.
