Vegetative
reproduction is method of multiplication in which a somatic part of the plant
detaches from the body of the mother and develops into a new independent part
under suitable environmental conditions. In Bryophyllum, vegetative
reproduction occurs through leaves. Leaves of Bryophyllum have adventitious buds
which help in vegetative reproduction. The adventitious buds arise from the
notches present at margins of leaves. These buds then grow into a new plant.
