Propagation of Tuberose

Propagation of Tuberose

Tuberoses are propagated by bulbs, bulblets, and seeds. Multiplication by bulb-segments and in vitro micro propagation from scale stem-sections is also practiced.

 

Propagation by bulbs

A most common method practiced for the commercial multiplication of tuberoses is through propagation by bulbs. The bulbs remain dormant during the winter months in places where the temperature is low. The dormancy of the bulbs can be successfully broken by dipping the bulbs in 4% Thiourea solution for one hour of early planting is desired. Ethylene chlorohydrins can also be used for breaking the dormancy of bulbs. The bulbs are separated from the clumps by rubbing off the loose scales, and the long roots should also be removed. Selection of suitable bulbs is very important for successful cultivation. In general, spindle -shaped bulbs free from diseases having a diameter between 1.5 and 3.0 cm are suitable for planting. About 1.25 – 1.5 lakh bulbs (8 to 9 tons of bulbs) are required for planting one hectare.

 

Propagation by bulb segments

Propagation through mature bulbs is expensive. Therefore, multiplication of growing stock can be done by the division of bulbs. Large sized bulbs having 2.1 cm or more diameter are suitable for planting purpose. If the bulbs are very large, they are cut into 2 to 3 vertical sections, each containing a bud and part of the basal plate. Each of these sections is treated with copper fungicide and planted vertically in a rooting medium with its tip just showing above the surface. A moderately warm temperature should be maintained. New bulblets along with roots develop from the basal plate. At this stage, bulblets are transferred to the ground.
