Ornamental plants are essential
object of environmental aesthetic beautification and management; they make up
the component of urban green spaces, public parks and houses more for
relaxation and enjoyment . They are grown for the display of aesthetic features
including flowers, leaves, scent and overall foliage texture- fruit, stem and
bark. They are a valuable tool for the harmonious and practical resolution of
many physical site problems, and they provide durable aesthetic satisfaction.
Generally, most perennial
ornamental plants are multiplied and propagated through asexual means of
reproduction such as cuttings, layering or grafting.
The cuttings from stems, leaves,
roots or terminal buds were the commonly used techniques, due to their ability
to retain the characters of the parent and also, for breeding seedless hybrid.
Success of rooting ornamental plant cuttings depend on their growth responses,
based on nutrient present with the aid of growth promoting substances before
planting.
Euphorbia milii, Adenium obesium,
and Murraya paniculata were known as ‘difficult to root’ ornamental plants,
this difficulty led to research on propagating their stem cuttings in different
growth promoting substances to observe their responses. Studies have shown that
physiological state of the mother plant, the prevailing environmental
conditions in the nursery i.e., light, temperature and humidity play important
role in rooting and developmental stages of cuttings.
