Origanum acutidens(HAND.-MAZZ.) IETSWAART is a promising ornamental plant that can be widely used in landscape management. It is endemic to Eastern Anatolian region of Turkey. Tissue culture has not been used to micropropagate it. The study reports stem node explants from one-week-old seedlings of the plant for successful micropropagation. The stem nodes were cultured on MS medium containing 0.6, 1.2, 1.8, and 2.4 mg/L BAP with 0.2 mg/L NAA. Visible effects of culture media on shoot proliferation were recorded. Shoot regeneration rate was maximum on MS medium containing 1.80 mg/L BAP-0.2 mg/L NAA. The micropropagated shoots were rooted on MS medium containing 0.2 mg/L NAA. All microrooted plantlets survived during acclimatisation on peat moss. It was concluded thatO. acutidenscan be successfully micropropagated underin vitroconditions.

Complete Procedure

Abstract The goal of this work was to look at the propagation of Reseda lutea L. by organogenesis in tissue culture. Explants from in vitro grown seedlings were taken from the axillary bud. After seven days of culture on MS medium supplemented with 1.0 mg/l BA, the adventitious buds developed. After three weeks of culturing on MS medium supplemented with 1.5 mg/l BA, the maximum multiplication of shoots (16.12 shoots/explant) was discovered, with an average (7.37 cm) shoots/explant. These shoots were sub-cultured on MS media with varying concentrations of NAA and IBA for root initiation. The MS medium combined with IBA produced the greatest percentage of root development (92%) and the greatest number of roots (7.37 roots/plant). In MS media supplemented with 0.5 NAA, the longest roots (3.08 cm) were found. After 17 days in a glasshouse, the plantlets were acclimatized in pots containing Peat moss and pearlite, 98 percent of the plantlets were acclimatized. To get a plant in a pot, the complete procedure took about 75 days. The technique proposed could aid in the preservation of the plant both in vivo and in vitro.

Tissue Culture Propagation

Three spineless phenotypes of Acacia wrightii G. Bentham ex A. Gray were identified with aesthetic landscape potential. Experiments in seed, cutting, grafting, and tissue culture propagation were undertaken to perpetuate this desired spineless phenotype. Germination percentages for mechanically scarified seeds ranged from 33% to 94%, however yield of spineless seedlings was low (0% to 34%). Sulfuric acid scarification for 10, 20, 30, or 60 minutes hastened and unified germination compared to nontreated seeds by 7 to 8 days. Vegetative propagation was successful for softwood cuttings. Rooting measures increased with auxin (2:1 indole butyric acid to naphthalene acetic acid) concentrations from 0 to 15000 mg·L–1, with maximum rooting percentage (70%), root number (9.2), and root length (12.4 cm) per softwood cutting at 15000 mg·L–1 auxin 8 weeks after treatment. Rooting was not successful for semi-hardwood or hardwood cuttings. Whip-and-tongue or T-bud grafting was not successful. Tissue culture of shoots from in vitro germinated seedlings indicated that shoot proliferation was greatest in Murashige and Skoog (MS) medium with 15 μm zeatin. The number of shoots that rooted in vitro increased with increasing concentrations of indole-3-butyric acid from 0 to 25 μm.

The Cost

The main obstacles in the commercialization of seedlings mass propagation through tissue culture techniques is the high cost of the culture media component. therefore, the production of lowcost tissue culture is required. This study aims to develop low cost in-vitro media for the production of the seedlings of Barangan banana. The research was composed following Factorial Completely Randomized Design, the first factor was Terra Novalgro liquid fertilizer with three concentrations, namely 1, 2, and 3 ml L-1, while the second factor was Gandasil with 3 concentrations namely 1, 2, and 3 mg L-1, so obtained nine treatments, each treatment was repeated 10 times, so that there were 90 experimental units. MS media was used as control. The parameter observed was number of shoots, number of leaves and number of roots. The results of this study exhibited that the treatment of 1 ml L-1 liquid fertilizer + 2 mg L-1 foliar fertilizer produced 9.30 shoots/explant and 1.90 leaves/explant, that no significantly different from MS medium (control) which produced 9.0 shoots/explant and 0.3 leaves/explants. Therefore, the using completed liquid fertilizers and foliar fertilizers as medium in vitro propagation of barangan bananas can become an alternative replace MS medium, as well as reduced the cost of culture media as 91% -93% compared to MS media.

This study describes a simple and promising for in vitro multiplication of Tabernaemontana fuchsiaefolia, a species abundantly found in southern Brazil utilized for medicinal purposes and as a source of compounds that may be used to develop new synthetic drugs. Apical and hypocotyl explants were cultured in MS medium containing different concentrations of the cytokinins benzylaminopurine (BA) and 6-furfurylaminopurine (kinetin), supplemented with phloroglucinol (1, 3, 5-hydroxybenzene) to stimulate growth and shoot proliferation. Cytokinin added to the culture media positively influenced the micropropagation of T. fuchsiaefolia.and kinetin induced more shoots per explant than BA cytokinin. A favorable effect of phloroglucinol on apical and lateral buds from hypocotyls was also achieved in medium containing no kinetin or in all kinetin concentrations tested. Short pulses of auxin 3-indolebutyric acid (IBA) 5.0 mg/l resulted in satisfactory rooting in apical microcuttings. The addition of phloroglucinol to MS medium induced rhizogenesis in 29% of the nodal segments transferred to MS medium in the absence of IBA and in 50% of the nodal segments transferred to MS medium containing 0.5 mg/l IBA and in nodal segments previously submitted to short pulses of IBA.

There are few reports in literature on the in vitro behavior of cambui tree (Myrciaria tenella O. Berg) and acclimatization conditions. The aim of this study was to evaluate the effect of culture media on in vitro germination and the effect of different substrates on the acclimatization of two Myrciaria tenella types. The study was carried out at the Embrapa Tabuleiros Costeiros Laboratory of Plant Tissue Culture, Aracaju, SE. Seeds were extracted from fruits of two Myrciaria tenella types: Orange and Purple Types. The seeds were inoculated in the following culture media: T1 - MS medium + 30g L -1 sucrose, T2 - 1/2 MS medium + 15g L -1 sucrose and T3 - control without MS salts. To study the effect of substrates on acclimatization, seedlings were transferred to plastic containers with capacity of 300cm 3 containing the following sterilized substrates: S1 - soil and powdered coconut husk - SPC (1:1 by volume); S2 - soil, washed sand and powdered coconut husk - SAPC (1:1:1 by volume) and S3 - Biomix (r) commercial substrate - SC. The medium without MS salts promoted 100% in vitro germination and 1/2 MS medium greater development of seedlings. All substrates studied are suitable for acclimatization of seedlings germinated in vitro. Myrciaria tenella of yellow type showed greater vigor during acclimatization.

The objective of this study was to investigate the possibility of optimizing routine tissue culture methods to proliferate two sweet cherry cultivars Karešova and Rivan. Shoot tips of two genotypes were successfully established <i>in vitro</I>. Six proliferation MS media containing 1, 2 and 4 mg/l BAP (6-benzylaminopurine), 0.5 and 1 mg/l TDZ (thidiazuron) or 10 mg/l 2iP (6-(&gamma;, &gamma;-dimethylallylamino)purine) were tested. The highest proliferation rate (3.0 ± 0.1) was obtained for Rivan on MS medium containing 2 mg/l BAP. In the case of cultivar Karešova, any of the cytokinins tested did not promote satisfactory proliferation. The highest proliferation rate (1.6) achieved on MS medium with 2 mg/l 2iP is not sufficient for a larger scale <i>in vitro</i> shoot production. It was proved that different genotypes of sweet cherry do not respond in the same way during proliferation <i>in vitro</i>. Future research and testing of other media and plant growth regulators will be carried out.

In this study, several methods have been used to facilitate shoot formation from nodal explants of local almond ecotypes known as “Beldi” grown in Eastern Morocco. Nodal segments of divers old local genotypes were cultured on various concentrations of auxin (indole-3-butyric acid (IBA)) and cytokinins (6-benzyl-aminopurine (BAP), thidiazuron (TDZ), and kinetin (KIN)) added to two different media (Murashige and Skoog (MS) and Heller medium). The results showed that TDZ was more effective than the other tested hormones for in vitro proliferation of the “Beldi” ecotype. TDZ at the concentration of 1 mg/L significantly improved the nodal shoot proliferation rate, with the highest percentage (63.6% ± 0.63) and number of regenerated shoots (13 ± 0.54) recorded for S1 genotype inoculated on MS medium, while the most significant rooting rate (60.41% ± 0.81) of proliferated shoots and number of roots per shoot (7.3 ± 1.36) were achieved for S2 genotype on 1 mg/L of IBA incorporated to a half-strength MS medium. With 80% of plantlets survival, the rooted shoots were successfully adapted to the in vivo conditions and were grown vigorously in the greenhouse without any morphological abnormalities.

The objective of this study was to establish cell suspension culture and plant regeneration via somatic embryogenesis of a Brazilian plantain, cultivar Terra Maranhão, AAB. Immature male flowers were used as explant source for generating highly embryogenic cultures 45 days after inoculation, which were used for establishment of cell suspension culture and multiplication of secondary somatic embryos. Five semisolid culture media were tested for differentiation, maturation, somatic embryos germination and for plant regeneration. An average of 558 plants per one milliliter of 5% SCV (settled cell volume) were regenerated in the MS medium, with 11.4 µM indolacetic acid and 2.2 µM 6-benzylaminopurine. Regenerated plants showed a normal development, and no visible somaclonal variation was observed in vitro. It is possible to regenerate plants from cell suspensions of plantain banana cultivar Terra using MS medium supplemented with 11.4 µM of IAA and 2.2 µM of BAP.

A high frequency of bulblet regeneration was achieved for the endemic and endangered ornamental plant Muscari azureum using immature embryos. Immature embryos of M. azureum were cultured on a callus induction medium consisting of N6 mineral salts and vitamins, 400 gL-1 casein + 40 gL-1 sucrose + 2 mgL-1 L-proline, 2 mgL-1 2,4-D and 2 gL-1 Gelrite. Then the embryogenic callus clusters were transferred to a bulblet induction medium consisting of MS mineral salts and vitamins containing different concentrations and combinations of BAP, KIN, TDZ, Zeatin, IAA, NAA, 30 gL-1 sucrose and 7 gL-1 agar. Prolific bulblet multiplication (over 13 bulblets/embryo) was achieved from immature embryos after 5-6 months of culture initiation. Well-developed bulblets were excised and individually rooted on ? strength MS medium supplemented with 1 mgL-1 IBA, 0.5 gL-1activated charcoal, 20 gL-1sucrose and 6 gL-1agar and acclimatized. <br><br><font color="red"><b> This article has been retracted.
