Plant Propagation

ASEXUAL OR VEGETATIVE PROPAGATION

Asexual propagation is used to produce a plant identical in genotype with the source (mother) plant. It is the propagation of plants using plant parts. e.g. stems, buds, leaf, roots through different methods: - cuttings - layering - budding - grafting The main advantage is that plants grown by asexual propagation methods will be the same ...

BASIS OF PROPAGATION BY CUTTINGS

In propagation by stem and leaf-bud cuttings (single-eye cuttings), it is only necessary that a new adventitious root system be formed, since a potential shoot system (a bud) is already present. Adventitious roots form naturally on various kinds of plants. Preformed roots, wound roots, wound roots. Herbaceous Plants, Woody Perennial Plants...

GERMINATION OF SEEDS

Seeds have everything required to form a new plant enclosed within themselves, so they wait until three vital environmental conditions have been met: an ample supply of water,optimum temperature, and situated in a well-aerated location. Stages and types of germination. Germination is the growth of the embryo into a young plant or seedling, Warmth, ...

GERMINATION STAGES OF SEEDS

Equipped with everything needed to make a new plant, a seed simply waits until three vital environmental conditions have been met: An ample supply of water, optimum temperature, situation in a well aerated location. The process of germination involves several stages. First stage the seed must take in water so that cells in its various structures be...

LEAF CUTTINGS

Basically, this method of propagation capitalises on the ability of leaves to initiate roots from primary or secondary meristem that has developed in the lamina or petiole. Development of shoots follows. Usually, the leaf (section or whole) originally prepared, forms no part of the new plant(s) - the part used for propagation disintegrates in tim...

MARCOTTING

Marcotting is the recognised international horticultural term for aerial layering from the French word 'marcotte' that means 'to aerial layer'. The basic principle is to cincture the branch by completely removing a section of bark right around the branch to a width of 1 - 4cm depending on branch diameter. A suitable rooting med...

METHODS OF SOWING SEED

Mechanical seeders: Hand sowing. Small home made seed shakers. Fertispray sowing. Fertiliser spreaders. Hydromulching. Mulching over planted seeds: -stops seed drying out. -reduces temperature fluctuations. -stops washing/blowing away. -prevents birds. -prevents weeds. -stops crusting of the soil....

MOTHER PLANTS OR STOCK PLANTS

Mother plants are best grown in large containers, where they can be looked after carefully and protected by regular spraying. Ensure excellent drainage around and beneath the containers. Maintain the area so that soil or water does not splash onto the plants. Water Stress, Temperature, Light, Stock Plant Etiolation, Carbon Dioxide Enrichment, Carbo...

PLANT PROPAGATION TERMINOLOGY

Grafting is the art of connecting two pieces of living plant tissue together in such a manner that they will unite and subsequently grow and develop as one plant. Budding is similar to grafting except that the scion is reduced in size to usually contain only one bud. Stock(rootstock, understock)is the lower portion of the graft, which develops into...

PROPAGATION MEDIA

The material or combination of materials that you use as a propagation media should have the following properties: The media should provide good physical support to the plants.Propagation media should have the following chemical properties: It should be chemically stable during use. For most plants it should have a pH in the range of 4-6 (some pla...
