Bud:-

A bud is a condensed young shoot with underdeveloped leaves. Cabbage is the largest bud.

There are three types of buds- (i) vegetative (ii) floral (iii) modified

According to position buds can be Lateral or terminal.

Lateral Buds: These are of four types:

• Axillary:- Present in the axil of leaf
• Accessory:- Additional buds occurring either on the side or above the axillary bud.
• Extra axillary:- Developing on the node but outside the leaf base.
• Adventitious buds:- Formed from places other than nodes of stem or branches. These can be:

• Cauline buds: These buds arise directly from the stem. e.g. jackfruit (Artocarpus)
• Radical buds: These buds develop on the roots; e.g. sweet potato, Ipecac, Dalbergia, Ipomoea
• Foliar buds: These are the buds which develop on the leaves; e.g. Bryophyllum, Begonia
