Labisia Pumila

Labisia pumila or locally known as ‘Kacip Fatimah’ is an herbaceous plant commonly used for dysentery, flatulence, dysmenorrhoea and gonorrhoea. A study was undertaken to investigate the effect of different plant growth regulators at various concentrations on adventitious root induction from the leaf explants of Labisia pumila. Murashige and Skoog (MS) medium supplemented with auxins; indole-acetic acid (IAA), indole-butyric acid (IBA) and naphtaleneacetic acid (NAA) each at the concentrations of 0, 1, 3, 5, and 7 mg/L were evaluated for their effects on adventitious root induction. No adventitious roots formed in the control medium devoid of any PGRs. Among the plant growth regulators (PGRs) used, IBA showed the best adventitious roots formation for all explants, followed by NAA and IAA. Leaf explants cultured on MS medium supplemented with 5 mg/L of IBA showed the best rooting ability. In this treatment, 72.4 ± 9.3 % of rooting, 17.8 ± 9.4 roots per explants and 0.123 ± 0.096g of dry weight were recorded. NAA and IAA showed ability to induce adventitious roots from leaf however the rooting ability was relatively lower that IBA treatment. The highest rooting ability for NAA and IAA was achieved in 7 mg/L and 3 mg/L with (71.2 ±10.9 % and 10.6 ± 3.6%) of rooting, (14.9 ± 0.669 and 1.60 ± 0.179) roots per explants and (0.044 ± 0.002g and 0.014 ± 0.001g) of dry weight, respectively.

Lulo is a species of great importance to the fruticulture of Colombia, but has significant phytosanitary problems that require an aggressive breeding program oriented toward the production of genotypes with tolerance to phytopathogens. These programs need to establish highly efficient mass plant propagation protocols, such as somatic embryogenesis. This study focused on research on the somatic embryogenesis of lulo using kinetin, naphthalene acetic acid-NAA (Plant Growth Regulators, PGRs), and different sucrose concentrations in a MS medium. Two lulo varieties, Solanum quitoense var. septentrionale and S. quitoense var. quitoense, and two explant types (hypocotyl and cotyledon) were used, incubated in dark conditions at 25±2°C. The highest production percentage of the embryos was obtained when 50 mM of NAA were added to the medium with sucrose (50.0 and 263.1 mM) for the two explant types used. In lulo with spines, the highest percentage of embryonic structures (50%) was observed with cotyledonary leaf explants and 50 mM of NAA ; while in the spineless lulo, the embryonic structures were observed in the same type of explant with 50 mM of NAA + 263.1 mM of sucrose (32%).

Step Procedure

A method for micropropagation of the endangered <em>Rubus chamaemorus</em> L. (<em>Rosaceae</em>) from shoot tips was developed. Murashige and Skoog (MS) medium supplemented with BA and IBA in different concentrations was used for axillary shoot development. The most effective was MS medium containing 0.88 µM BA and 0.49 µM IBA with value of pH = 4.0. Cultures of microshoots (up to 12 shoots from a single explant) developed into regular shoots on the same medium or after transferring them onto MS media with 0.44 µM BA, 0.49 µM IBA and 434 µM SA. The rooting of initiated axillary shoots proved extremely difficult. A two-step procedure for root induction was adopted. Auxin- treated shoots were put to medium devoid of plant growth regulators. Rooted shoots were then transferred to pots and grown in the greenhouse until planted in the ground of the Botanical Garden.

<p class="IsiAbstrakIndo"><em>Justicia gendarussa </em>Burm.f., a medicinal plant, is Acanthaceae that has many functions. Furthermore, the compounds in gendarussa must be produced in high quantity and quality by applying callus culture method. Accordingly, it is important to study the effects of plant growth regulators (2,4-D, IBA, and BAP) on callus induction of gendarussa leaves. This research design utilized a factorial design with two factors (2,4-D and IBA: 0.5, 1, 1.5 mg/L and BAP: 0.5, 1, 1.5, 2 mg/L). The experiment consisted of 24 treatments, each of which was repeated 3 times. Observation was carried out in 6 weeks. Data on the time of callus formation, percentage of explants formed callus, and callus morphology were analyzed descriptively,while data on fresh and dry weight were analyzed by Two-Way ANOVA (<span>α</span> = 0.5). Interestingly, the results showed that various concentration of plant growth regulators (2,4-D, IBA, and BAP) affected callus induction from leaf explants of gendarussa. We concluded that the most optimal treatment combination of concentration of plant growth regulators in inducing callus from leaf explants of gendarussa is 1.5 mg/L 2,4-D and 2 mg/L BAP with a relatively long period of callus formation at the earliest, i.e. on day 5, 2.247 g of fresh weight, 0.108 gof dry weight, white callus translucent, and friable. <span lang="EN-GB">Moreover, t</span>he optimum treatment will be used to produce secondary metabolite and seed s<span lang="EN-GB">y</span>nthetic by cell suspension culture.</p>

Adventitious Root Culture

Andrographolide is the principal bioactive component of the medicinal plant Andrographis paniculata, to which various diverse pharmacological properties are attributed. Traditionally, andrographolide was extracted from the leaves, stems and other parts of the plant. Leaves have the highest andrographolide content (2–3%) in comparison with the other plant parts. Adventitious root culture of leaf explants of A. paniculata was studied using different strength MS medium supplemented by different concentrations of auxins and a combination of NAA + kinetin for growth and andrographolide production. Among the different auxin treatments in adventitious root culture, only NAA was able to induce adventitious roots. Adventitious roots grown in modified strength MS medium showed the highest root growth (26.7±1.52), as well as the highest amount of andrographolide (133.3±1.5 mg/g DW) as compared with roots grown in half-and full-strength MS medium. Growth kinetics showed maximum biomass production after five weeks of culture in different strength MS liquid medium. The produced andrographolide content was 3.5- 5.5 folds higher than that of the natural plant, depending on the medium strength.

P. vietnamenseO. Gruss & Perner is one of the endemic lady’s slipper orchids in Vietnam that has been known as an endangered species threatened with extinction due to over-collection. To protectP. vietnamensespecies,In Vitropropagation method needs to be established for producing plantlets that can be introduced back in wild, as well as commercialized. In this study, we examined the effect of basal culture medium, plant growth regulators, and AC on the micropropagation ability ofP. vietnamense, which were collected from wild population in Thai Nguyen province, Northeastern Vietnam. We determined that the 0.2% HgCl2can be used in within 5 to 10 min for sterilizing axillary buds ofP. vietnamense, resulting in 65.55% of disinfected samples. Moreover, the 1/2 MS medium supplemented with 2.0 mg 1-1BA and 1.0 mg 1-1NAA, which gave about 2.85 shoots/sample, was the most suitable for shoot regeneration and multiplication. In addition, the result also indicated that 0.5 mg 1-1NAA and 1.0 g 1-1AC gave the best results (88.89%) for root induction and plantlets

Ginger (Zingiber officinale Roscoe) var. Bentong is a monocotyledon plant that belongs to the Zingiberaceae family. Bentong ginger is the most popular cultivar of ginger in Malaysia, which is conventionally propagated by its rhizome. As its rhizomes are the economic part of the plant, the allocation of a large amount of rhizomes as planting materials increases agricultural input cost. Simultaneously, the rhizomes’ availability as planting materials is restricted due to the high demand for fresh rhizomes in the market. Moreover, ginger propagation using its rhizome is accompanied by several types of soil-borne diseases. Plant tissue culture techniques have been applied to produce disease-free planting materials of ginger to overcome these problems. Hence, the in vitro-induced microrhizomes are considered as alternative disease-free planting materials for ginger cultivation. On the other hand, Bentong ginger has not been studied for its microrhizome induction. Therefore, this study was conducted to optimize sucrose and plant growth regulators (PGRs) for its microrhizome induction. Microrhizomes were successfully induced in Murashige and Skoog (MS) medium supplemented with a high sucrose concentration (>45 g L−1). In addition, zeatin at 5–10 µM was found more effective for microrhizome induction than 6-benzylaminopurine (BAP) at a similar concentration. The addition of 7.5 µM 1-naphthaleneacetic acid (NAA) further enhanced microrhizome formation and reduced sucrose’s required dose that needs to be supplied for efficient microrhizome formation. MS medium supplemented with 60 g L−1 sucrose, 10 µM zeatin and 7.5 µM NAA was the optimum combination for the microrhizome induction of Bentong ginger. The in vitro-induced microrhizomes sprouted indoors in moist sand and all the sprouted microrhizomes were successfully established in field conditions. In conclusion, in vitro microrhizomes can be used as disease-free planting materials for the commercial cultivation of Bentong ginger.

Amygdalus Communis

The Almond (Amygdalus communis) is one of the most important and oldest commercial nut crops, belonging to the Rosaceae family. Almond has been used as base material in pharmaceutical, cosmetic, hygienically and food industry. Propagation by tissue culture technique is the most important one in woody plants. In the current research, in vitro optimization of tissue culture and mass production of almond was investigated. In this idea, explants of actively growing shoots were collected and sterilized, then transferred to MS medium with different concentrations and combinations of plant growth regulators. The experiment was done in completely randomized blocks design, with 7 treatment and 30 replications. After 4 weeks, calli induction, proliferation, shoot length and number of shoot per explants were measured. Results showed that the best medium for shoot initiation and proliferation was MS + 0.5 mg/l IAA (Indol-3-Acetic Acid) + 1 mg/l BA (Benzyl Adenine). Autumn was the best season for collecting explants. The shoots were transferred to root induction medium with different concentrations of plant growth regulators. The best root induction medium was MS + 0.5 mg/l IBA (Indol Butyric Acid).
