Synopsis (short abstract) Plants have two ways of reproduction, sexual by means of seeds, and asexually or vegetative by means of vegetative tissue. Both ways occur in living plants in nature. Genetically the two ways of reproduction differ. Seeds contain genes from the female parent-wherewe collect the seeds- and the male parent-which contribute the pollen and which is often unknown. There are four main uses of vegetative propagation in a Tree Breeding Programme: the establishement of clonal seed orchards, the establish ment of clonal banks, the propagation of special breeding material, and mass propagation of selected materials.

    Effect of cutting dimensions, rooting media and incubation on vegetative propagation of Prunus armeniaca
    XV World Forestry Congress, 2-6 May 2022

    Propagation through cuttings of Prunus armeniaca – a tree borne oilseed of mid hills and dry temperate regions in India was tested by using three treatments. Vegetative propagation provides the opportunity in multiplication by cuttings by providing true-to-its-type plant and producing superior individuals. Effect of length and diameter, type and concentration of auxin and incubation method and duration on rooting of cuttings in wild apricot was studied. The study concluded that the optimal condition for rooting percentage in P. armeniaca is maximum using the incubator for 18 days on cutting length of 15 cm and cutting diameter of 1.0-1.5 cm after the application of IBA @ 5000 ppm. The survival percentage was also enhanced from 50.00 % to 53.33 % when cutting length of 15 cm and cutting diameter of 1.0-1.5 cm with IBA @ 5000 ppm incubated for 18 days at 30oC.

    Mass Vegetative Propagation of Dipterocarp Species 1993
    Also available in:

    Dipterocarp species constitute about 70% of the commercial stock in the tropical forest of South Asia, which used to be the mainstay of the timber industry in the region. Dipterocarp wood made up 25% of the world trade in harwood until the end of the logging boom in the 1970s, and now the fragile ecosystem of the dipterocarp forest has been disturbed and their very existence has been threatened. It is of extreme urgency, therefore, to adopt sustainable measures to conserve, restore and enrich th e dipterocarp forest to make it more viable for economic and ecological considerations.
