explain vegetative propagation in bryophyllum/?
Vegetative reproduction (vegetative propagation, vegetative multiplication, vegetative cloning) is a form of asexual reproduction in plants. It is a process by which new individuals arise without production of seeds or spores. It can occur naturally or be induced by horticulturists.
Although most plants normally reproduce sexually, many have the ability for vegetative propagation, or can be vegetatively propagated if small pieces are subjected to chemical (hormonal) treatments. This is because meristematic cells capable of cellular differentiation are present in many plant tissues. Horticulturalists are interested in understanding how meristematic cells can be induced to reproduce an entire plant.
Success rates and difficulty of propagation vary greatly. For example willow and coleus can be propagated merely by inserting a stem in water or moist soil. On the other hand, monocotyledons, unlike dicotyledons, typically lack a vascular cambium and therefore are harder to propagate.
Vegetative Reproduction is a type of asexual reproduction in which new plants are produced from the vegetative parts i.e. roots, stems, leaves and buds of the parent plant. Since, reproduction is through the vegetative parts of the plant, it is called vegetative propagation.
In some plants like Bryophyllum (sprout leaf plant) the leaf has many buds on its margins. A new plant arises from these buds when the leaf falls on the moist soil. This is known as vegetative propagation by leaves.
