Irises are perennial plants widely used as ornamental garden plants or cut flowers. Some species accumulate secondary metabolites, making them highly valuable to the pharmaceutical and perfume industries. Micropropagation of irises has successfully been accomplished by cul ...

Micropropagation is an important tool for rapid multiplication and the creation of genetic variability in African violets (Saintpaulia ionantha Wendl.). Successful in vitro propagation depends on the specific requirements and precise manipulation of various factors such as t ...

This protocol describes an efficient and rapid method for large-scale multiplication of Cordyline terminalis in a cost-effective manner. Actively growing shoot tips were selected as explants. Murashige and Skoog (MS) basal medium was supplemented with different plant growth reg ...

Helleborus genus, belonging to the Ranunculaceae family, has 20 species of herbaceous perennial flowering plants. The commercial exploitation of this plant is dependent on the selection and propagation of appropriate lines. High propagation rate could be accomplished by using a sui ...

Fraser photinia (Photinia � fraseri Dress.) is a woody plant of high ornamental value. The traditional propagation system for photinia is by rooting apical cuttings using highly concentrated auxin treatments. However, photinia micropropagation is an effective alternative to tra ...

Hydrangea (Hortensia) is a highly popular ornamental plant for garden decoration, and now it is commercially produced for cut flower branches. For in vitro culture, Murashige and Skoog medium supplemented with BA (0.25 mg/L) and sucrose (30 g/L) was used. Culture conditions were 23 � 1�C of tempera ...

Paradise tree (Melia azedarach L.) is a multipurpose ornamental and timber tree, and its extracts are used to make insecticides and fungicides. Conventional propagation is done by seeds; however, sexual reproduction results in wide genetic variability. Therefore, clonal propagati ...

Induction of somatic embryogenesis is described in common ash (Fraxinus excelsior L.). Embryogenic tissues are obtained from immature zygotic embryos and cultured on a modified Murashige and Skoog (MS) medium containing 8.8 μM 2,4-dichlorophenoxyacetic acid and 4.4 μM benzyl-aden ...

Acacia mangium and A. mangium � A. auriculiformis hybrids have gained an increasing interest in reafforestation programs under the humid tropical conditions, mainly for pulpwood production. This is due to their impressive growth on acid and degraded soils, as well as their capability to re ...

Lavandula species are some of the most popular ornamental and medicinal plants with great economic values. These species are vegetative propagated by stem cuttings. However, the poor rooting ability and vulnerability of plantlets to contamination are major limiting factors for pro ...

Peach (Prunus persica (L.) Batsch) is one of the most popular stone fruits, commercially produced largely in Mediterranean and, to a lesser extent, in continental climatic conditions. Several breeding programs with different aims release annually large numbers of new cultivars. Micro ...

Micropropagation is the most appropriate method for large-scale production of Rubus and Ribes spp. The proliferation rate of Rubus spp. differs in shoot tips and nodal segments. The culture media used for raspberry and blackberry propagation are MS-based supplemented with different c ...

The black chokeberry—aronia (Aronia melanocarpa Elliot) is a shrub native to North America although nowadays well known in Eastern Europe. The fruits are regarded as the richest source of antioxidant phytonutrients among fruit crops and vegetables. Chokeberries can be easily propag ...

Guava (Psidium guajava L.) is well known for edible fruit, environment friendly pharmaceutical and commercial products for both national and international market. The conventional propagation and in vitro organogenesis do not meet the demand for the good quality planting material ...

Persimmon (Diospyros kaki Thunb.) is a temperate fruit tree species diffused in all continents. The traditional propagation method adopted by the nursery industry is based on budding/grafting scion cultivars on seedlings from D. kaki, Diospyros lotus, and Diospyros virginiana, the mo ...

Peanut (Arachis hypogaea L.), also known as groundnut, is the most important species of Arachis genus, originating from Brazil and Peru. Peanut seeds contain high seed oil, proteins, amino acids, and vitamin E, and are consumed worldwide as edible nut, peanut butter, or candy, and peanut oil extract ...

Cherry tree micropropagation is limited to the production of healthy cultivars of Prunus avium and Prunus cerasus, and their rootstocks; mainly the dwarfing ones. By using meristem-tip (0.1 mm long) or healthy shoot tips/nodes, four successive steps are needed to obtain whole plants capable ...

Citrus spp., the largest fruit crops produced worldwide, are usually asexually propagated by cuttings or grafting onto seedling rootstocks. Most of Citrus genotypes are characterized by polyembryony due to the occurrence of adventive nucellar embryos, which lead to the production of ...

Garlic (Allium sativum L.) is a very important medicinal and spice plant. It is conventionally propagated by daughter bulbs (“cloves”) and bulbils from the flower head. Micropropagation is used for speeding up the vegetative propagation mainly using the advantage to produce higher numbe ...

The globe artichoke (Cynara cardunculus L. var. scolymus) is a perennial plant cultivated in the Mediterranean region and the Americas for its edible young flower heads. Although vegetative propagation by offshoots or by “ovoli” (underground dormant axillary buds) has been the primary m ...
