Plant propagation in a plants nursery

Plant propagation is the process of creating new plants from a variety of sources like seeds, cuttings, bulbs and other plant parts. It is mainly two types as sexual propagation and asexual propagation. Mostly asexual propagation is practiced by the company, while sexual propagation is limited for the palm varieties.

Asexual propagation

Mainly two types of asexual propagation methods are practiced by the company, which are cuttings and layering.

Cuttings

A plant cutting is a piece of a plant that is used in horticulture for vegetam To-sexual propagation. A piece of the stem or root of the mother plant is placed in a Jo medium and if the conditions are suitable, the plant piece will begin to grow plant. A stem cutting produces new roots and a root cutting produces new stem. However plants can be grown from leaf pieces, called leaf cuttings, which produce stems and roots (Anon, 2017).

Most ornamental plants are propagated by stem cuttings as it is a quick, easy and reliable method of propagating. Some of the ornamental plants that are propagated by stem cuttings are

Cuttings Continued……

Generally the cuttings of 10-15 cm in length, which includes 3-4 buds are made with a straight cut on top and a slant cut on the bottom. Straight cut on top of the cutting minimizes transpiration and the slant cut at the bottom increases nutrient uptake and surface area for rooting. These cuttings should be made using a sharp disinfected knife to minimize the wounding and infections. After the cuttings are prepared, rooting hormones should be applied in the lower surface of the cutting using a clean brush.

However, Then they are planted in a well irrigated basin type propagator which consists sand and half burnt paddy husk in 1:1 ratio. After that the propagator is covered with a polythene, tied well using a rope to prevent evaporation of water and date of the propagation is marked on the polythene. After 21 days the propagator is opened and healthy rooted cuttings are transplanted in pots and reared under net houses.

Adenium obesum and Zamioculcas zamifolia have a bit different methods of propagating cuttings. Adenium obesum soft wood cuttings of about 6 inches are made with the upper end straight and lower end slanted. Then they are kept under sunlight for few hours to dry out the latex before applying rooting hormones. The potting mixture should consist half burnt paddy husk, sand and chip stones in 1:1:1 ratio.
