“…Growth media supplemented with thidiazuron (TDZ) have been utilized only very occasionally, but this growth regulator is becoming more and more popular. The auxin incorporated most frequently into growth media to induce organogenesis is 1-naphthaleneacetic acid (NAA) at 2.7 µM (Pérez- Molphe-Balch et al, 1998;Mata Rosas et al, 2001;Moebius-Goldammer et al, 2003) followed by indole-3-acetic acid (IAA) at 0, 5.7, 11.4 and 22.8 µM, and indole-3-butyric acid (IBA). In general, 2,4-dichlorophenoxyacetic acid (2,4-D) is useful when the aim is to promote callus formation and/or somatic embryogenesis in different explants and plant species.…”

Cacti species are plants that are well adapted to growing in arid and semiarid regions where the main problem is water availability. Cacti have developed a series of adaptations to cope with water scarcity, such as reduced leaf surface via morphological modifications including spines, cereous cuticles, extended root systems and stem tissue modifications to increase water storage, and crassulacean acid metabolism to reduce transpiration and water loss. Furthermore, seeds of these plants very often exhibit dormancy, a phenomenon that helps to prevent germination when the availability of water is reduced. In general, cactus species exhibit a low growth rate that makes their rapid propagation difficult. Cacti are much appreciated as ornamental plants due to their great variety and diversity of forms and their beautiful short-life flowers; however, due to difficulties in propagating them rapidly to meet market demand, they are very often over-collected in their natural habitats, which leads to numerous species being threatened, endangered or becoming extinct. Therefore, plant tissue culture techniques may facilitate their propagation over a shorter time period than conventional techniques used for commercial purposes; or may help to recover populations of endangered or threatened species for their re-introduction in the wild; or may also be of value to the preservation and conservation of the genetic resources of this important family. Herein we present the state-of-the-art of tissue culture techniques used for ornamental cacti and selected suggestions for solving a number of the problems faced by members of the Cactaceae family.

Effect of substrate and rooting on acclimatization of in vitro propagated Melocactus glaucescens Buining & BrederooMelocactus glaucescens (Cactaceae) is endemic to Bahia and is included in the IUCN and MMA lists as endangered species. Transference of in vitro cultures to ex vitro environment is critical and can become limiting for the production of micropropagated scions. The main objective of this work was to examine the effect of different substrates and rooting during acclimatization of Melocactus glaucescens. The plants were in vitro propagated and kept in 100 % light, on daily cycles for 75 days. The results suggested that the best substrate should consist of 50 % soil and 50 % sand; plantlets should be at least 5mm in diameter and height before being transferred; and that both steps in vitro rooting and harding could be eliminated from micropropagation of M. glaucescens. Further studies are still needed on desiccation time of shoots above 5 mm so that the step of in vitro rooting can be completely eliminated.

“…In the last decades, tissue culture has been implemented to propagate many threatened and endangered cacti, e.g., Obregonia denegrii (Malda et al, 1999); Coryphantha elephantidens (Wakhlu and Bahu, 2000); Mammillaria elongata (Papafotiou et al, 2001); Pelecyphora spp. (Pérez-Molphe-Balch and Dávila-Figueroa, 2002); Ariocarpus kotschoubeyanus (Moebius-Goldammer et al, 2003); Turbinicarpus spp. (Dávila-Figueroa et al, 2005); Notocactus magnificus (de Medeiros et al, 2006); 10 different Mammillaria spp.…”

A rapid shoot multiplication protocol was established for the endangered cactus Mammillaria mathildae to reintroduce it to its natural habitat. In vitro-germinated seedlings were used as the source of explants. Three explant sources (apical, lateral, and basal excised from in vitro-germinated seedlings) were tested. Shoot multiplication was induced in Murashige and Skoog (MS) medium supplemented with different 6-benzylaminopurine/indole-3-acetic acid (BA/IAA) combinations (0, 22.19, 44.39 and 0, 1.43, 2.85, 5.71, respectively). Explants developed abundant callus in the presence of any BA/IAA concentration, whereas hormone-free media produced 0.59 ± 0.11 new shoots (with a 41% callus development) from basal explants. Apical and lateral explants produced 1.14 ± 0.07 and 4.09 ± 0.13 new shoots, respectively, without callus generation. Plantlets originating from lateral explants developed a vigorous rooting system after 2 months growing on MS medium supplemented with 30 g·L−1 sucrose. Under greenhouse conditions, 98% of micropropagated M. mathildae survived. Plantlets were reintroduced in an experimental plot near to Juriquilla's wild population of M. mathildae; over 52% of the outplanted M. mathildae lot declined after 5 months. Water availability was associated with the decline of outplanted populations during the first month (43%).
