MAKING NEW PLANTS BY CLONAL PROPAGATION

Growers want to produce new plants that are exactly like the mother plants that are found in the home, garden, nursery or greenhouse. To produce a plant which is genetically identical to the mother plant clonal (vegetative) propagation is needed. Propagation by the rooting of cuttings (adventitious root formation), root cuttings and division, stooling, layering, grafting and budding, and similar techniques can produce the desired clonal results. The selection of the method is dependant upon the plant variety. Propagation from seed while suitable for many plants, especially annual plants, often produce variable results. In-vitro propagation (micro-propagation), a relatively new technique, requires specialized equipment and many times does not produce new plants as expected.

Plants propagated from cuttings have the same characteristics as the parent plant. The rapid generation of new adventitious roots is necessary for the plant to transport water and essential nutrients from the media. Hortus IBA Water Soluble Salts rooting hormone treatment helps the plant to rapidly develop new roots when propagating from cuttings.

THE FINISHED PLANT

The most attractive plant is a symmetric plant. Using Hortus IBA Water Soluble Salts root stimulation takes place all around the basal end of the cuttings. Hortus IBA Water Soluble Salts products have unique formulas which induce uniform absorption of the active ingredients. After early and symmetric root formation the plant stands solid in the soil, it absorbs water and nutrients, develops uniform shoot, stem and leaf growth and superior total growth.

WHY TO USE ROOTING HORMONES

For adventitious rooting, all plants need plant growth regulator rooting hormones in order to produce roots on cuttings. To some extent these regulators are produced by the plant itself. Cuttings from different plant varieties and species have different ability to root. Some cuttings root easily, some are difficult to root, and some plants can not produce roots from cuttings. Hortus IBA Water Soluble Salts rooting hormones act with the plants own natural rooting regulators to aid root formation. The concentration of the induced regulator hormone should be adequate to induce root development and below the threshold to inhibit growth. Successful root formation helps the cutting to take up water and nutrient substances faster.
