Vegetative reproduction involves the production of a new plant from the vegetative part of the plant. In Bryophyllum, it takes place through leaf buds. The leaf of the Bryophyllum is broad and has several notches. The notch has buds which are known as epiphyllous buds which fall on the soil and germinates to form a new plant. It forms The bud has an adventitious root which helps in the anchorage.
Tissue culture involves the use of small pieces of plant tissue (explants) which are cultured in a nutrient medium under sterile conditions. Using the appropriate growing conditions for each explant type, plants can be induced to rapidly produce new shoots, and, with the addition of suitable hormones new roots.
