Evaluation of the irradiated banana (cv. Dwarf Cavendish) expants to salinity tolerance under in vitro conditions
... In lisianthus, somaclonal variants such as dwarf, miniature, or branched compared to the parent that was a tall single stem cultivar were identified (23). On the other hand, tissue culture has provided a tool for the plant breeding by in vitro selection (20,36), polyploidy induction (28,34), mutation (21,35) and genetic engineering (32). The development of procedures for rapid in vitro clonal micropropagation of any plants may be a great commercial value to the industry (10,11,17,31). ...
Ornamental plants are produced primarily for their artistic value, thus the propagation and improvement of quality attributes and the creation of novel variation are important economic goals for floriculturists. Micropropagation is an alternative mean of propagation that can be employed in mass multiplication of plants in relatively shorter time. Recent modern techniques of propagation have been developed which could facilitate large scale production of true-to-type plants. Successful in vitro propagation of ornamental plants is now being used for commercialization. Factors such as medium, plant growth regulators, carbohydrate and gelling agent which substantially affected on the success of plant tissue culture have been reviewed.
... Agents of artificial mutations are called mutagens (16). The mutagens are applied on seed, seedlings, cuttings, any plant part and also on in vitro plantlets ( Figure 1) (7,16,20). The frequency and types of mutations are direct results of the dosage and rate of exposure or administration of the mutagen rather than its type (16). ...
Floriculture has become an important industry in many countries as a result of advanced scientific techniques and stable supply of improved varieties. Development of new varieties and their fast marketing are major challenges in floriculture trade. Along with the increasing demand of ornamental plants in the world and the change of consumer’s preference, mutation induction produced a large number of new promising varieties in ornamental species. Furthermore, mutation breeding is well suited for ornamental plants because many species can be easily vegetatively propagated, facilitating the production of spontaneous and induced mutants. Among mutagens, gamma rays have been commonly used effectively for development of new varieties in ornamental crops. Some of the important ornamental plants, both cut and potted plants, that have been used for mutation breeding for example are: chrysanthemum, orchids, rose, pelargonium, canna, and carnation. Appropriate strategies in mutation induction as application of fractionated doses and recurrent irradiation combined with in vitro culture techniques may lead to rapid success in ornamental species.
