Clonal propagation of conifers
1991Conifers are the best known and most economically important of the gymnosperms, which make up approximately 60% of the forested areas of the world. There are about 50 genera and 300–500 species of conifers [24]. Pines (Pinus spp), spruces (Picea spp), firs (Abies spp), Douglas fir (Pseudotsuga), larch or tamarack (Larix spp), hemlock (Tsuga spp), bald ...

Rapid clonal propagation of Dioscorea zingiberensis
Plant Cell, Tissue and Organ Culture, 2003A protocol was developed for rapid in vitro propagation of Dioscorea zingiberensis Wright using stems as explants. MS medium with the macroelements at half strength and supplemented with 20.0 g l−1 sucrose and 8.0 g l−1 agar was used as basal medium.

TOWARDS THE CLONAL PROPAGATION OF COCONUT
Acta Horticulturae, 2002Past studies from our laboratory have shown that whole immature, or mature sliced, zygotic embryos are a very good starting explant for coconut somatic embryogenesis. The highest rate of somatic embryogenesis was obtained when certain polyamines were added into the culture medium as well as activated charcoal (AC) to absorb unwanted phenolics.

In spite of the many expectations on the application of tissue culture to plant improvement, clonal propagation is so far the only in vitro tissue culture technique widely used outside the research laboratories. Although most tissue culture techniques allowing plant regeneration have been proposed as suitable for clonal propagation, only axillary shoot

Clonal propagation of Leptospermum spp. by tissue culture
Plant Cell Reports, 1986Propagation by axillary and multiple axillary bud development was achieved in three native Leptospermum spp. when axillary buds derived from nodal tissues ex mature plants were placed in benzylaminopurine media (0.04-1.0 μM) containing macro- and micro-nutrients, sucrose (0.06 M) and a vitamin/amino acid supplement. Reduction of agar concentration from

Palm products, historically and currently, are important sources of economic revenues for sub-tropical and tropical countries (e.g. palm oil accounts for 15% of the world’s total vegetable oil) [20]. The only means of vegetative propagation in palms, being monocotyledons, is restricted to vegetative lateral bud outgrowths (offshoots) which are produced

Clonal Propagation of Primate Offspring by Embryo Splitting
Science, 2000Primates that are identical in both nuclear and cytoplasmic components have not been produced by current cloning strategies, yet such identicals represent the ideal model for investigations of human diseases. Here, genetically identical nonhuman embryos were produced as twin and larger sets by separation and reaggregation of blastomeres of cleavage ...

Ever since Knudson [3] developed a nonsymbiotic in vitro culture method for germination of orchid seeds, tissue (in vitro) culture has played an important and highly significant role in the cultivation, propagation, breeding and preservation of orchid species and hybrids.

The evolutionary ecology of clonally propagated domesticated plants
New Phytologist, 2010Summary While seed‐propagated crops have contributed many evolutionary insights, evolutionary biologists have often neglected clonally propagated crops. We argue that widespread notions about their evolution under domestication are oversimplified, and that they offer rich material for evolutionary studies.

Fruit tree species are generally heterogenous and elite selections have been usually propagated vegetatively to maintain their genetic makeup and superior characteristics. With the exception of species such as Betula, Populus and Prunus, regeneration of woody taxa in cell and tissue cultures has been rather elusive despite several years of research ...
