What are 3 examples of vegetative propagation?

Answer 1

B12Ph8_Natural MethodsVegetative reproduction by natural methods is very common among seed plants. Vegetative organs such as roots,

stems & leaves bear adventitious buds & bring about the formation of new plant s .

1) Vegetative reproduction by roots: The roots of some plants develop adventitious buds on them. E.g;

Daldergia (Shisham), Guava, Murraya, Albizzia lebbek, etc. Some tuberous adventitious roots besides

possessing adventitious buds also contain sufficient quantities of food, e.g; Dahlia & sweet potato. These

buds sprout under suitable conditions. These sprouts may be separated & planted. In Shisham (Tahli) young

fast growing shoots will arise from the roots around the cut stumps of trees.

Example: Sweet potato (Ipomoea batatas): It is a

modification of adventitious roots. These roots grow

from the nodes of a running stem & they are

irregularly swollen due to the storage of food, hence

they are called tuberous roots. They are called simple

tuberous because they arise singly (one at each node)

& not in clustures. They even give rise to

adventitious buds which when detached, can give

rise to new plants, thus performing the function of

vegetative propagation.

2) Vegetative reproduction by stem: Aerial weak

stems (runner, stolons) when they touch the ground,

give of adventitious roots. Thereafter, if connection

breaks from the parent plant, the portion with newly formed roots develops into an independent plant.

Stolon is also a weak aerial shoot which helps in vegetative propagation. E.g; Vallisneria. Straggling &

branched rhizomes also reproduce by vegetative propagation. E.g;Banana, Ginger, Turmeric. Decay of

older parts isolate the newly formed branches. The latter henceforth leads an independent life. Corms like

Colocasia (Kachalu), Freesia, Crocus etc. have sufficient stored food & also bear many adventitious buds.

A bulb also bears a number of buds E.g; Garlic & Narcissus. The buds are separated & develop into new

plants.

· Stem Tuber: Tuber of potato is a swollen apical part of an underground stem branch & bears number

of nodes or eyes. Each eye bear one or many buds. New plants are produced from the buds present on

the eye. The suckers of Mint & Chrysanthemum also serves as organ for vegetative multiplication.

Bulbils are small, fleshy speacialized buds. They fall on the ground & produce new individuals. E.g;

Agave (Century plant), Dioscorea & Pineapple. In agave flower buds develop into bulbils which drop

on ground to produce new plants thus doing vegetative propagation from reproductive organs.

Underground stem of potato, Onion & Zamicand are used for vegetative propagation. The plants with

subaerial modification like in Pistia, Eichhornia & Pineapple are used for multiplication of plants.

Runner *: The runner is a slender prostate branch with a short & long internodes. It rises from the base

of the plant. It creeps on thr ground & roots at nodes. Runner arises from the axillary bud & creeps

away some distance from the parent plant. It produces roots & grow into new plant. It may break off

the parent plant.Many runners are produced from a mother plant. They spread on the grounds on all

sides.On getting detached from the parent plant, the shoot develops as independent plants. The runner

is meant for vegetative propagation. E.g; Cynodon, Strawberry, Grasse etc.

3) Vegetative propagation by Leaves: In some plants adventitious buds are developed on their

leaves. E.g; Bryophyllum, Begonia, Streptocarpus, Kalanchoe & Saintpaulia. In Bryophyllum notched

margins of succulent leaves bear adventitious buds. These buds usally remain dormant,when the leaf is

attached with the plant. However when the leave come in contact with the soil,develop new plantkets along

the margins. However in some species of Bryophyllum, plantlets develop along the margins of intact

leaves. In Begonia & Sensevieria adventitious buds are produced at the place of injury
