<p>Vegetative<br />propagation through in vitro culture has been carried out as<br />a technology that has the potential for obtaining seedling in<br />significant amounts and relatively faster. This activity can be<br />done through the multiplication of adventitious shoots and<br />lateral shoots (organogenesis). The goal of this research was<br />to find the method of cashew micropropagation through<br />organogenesis. This study consisted of 4 main activities.<br />They were shoot induction, shoot multiplication, shoot<br />elongation, and root induction. The results showed the best<br />medium composition for shoot induction was MS + BA 0.7<br />mg/l. The suitable media for shoots multliplication was MS +<br />thidiazuron 0.5 mg/l + zeatin 1 mg/l and for shoots<br />elongation was MS + GA 1 mg/l + zeatin + 3 mg/l. The best<br />methods for root induction was by submerging in vitro<br />shoots in a solution of IAA 100 mg/l.</p>

Vitro Production

This study investigated in vitro production of diploid (AS2) and tetraploid (AS4) cytotypes of snowdrop anemone. The effect of plant growth regulators (PGRs) on in vitro shoot multiplication and rooting was investigated. The effect of activated charcoal (AC) on root induction was also studied. Ploidy level affected growth characteristics during multiplication and rooting. Shoot induction in AS4 was higher on medium supplemented with cytokinin (3.2–3.6), while the AS2 clone formed the most shoots on PGR-free medium (3.6). The highest rooting percentage was achieved on PGR-free medium in both genotypes (AS2 clone, 100% and AS4 clone, 93.3%). The addition of AC to the PGR media largely increased root induction and root length. Rooted plantlets were successfully acclimatised in the greenhouse with 100% survival. Thus, the described micropropagation protocol represents a rapid and effective in vitro propagation method for utilisation in horticulture and conservation programmes of snowdrop anemone.

Shoot Cultures

An efficient micropropagation protocol of Cyclopia genistoides (L.) Vent., an indigenous South African shrub of economic importance, was established. In vitro shoot cultures were obtained from shoot tip fragments of sterile seedlings cultured on solid Schenk and Hildebrandt (SH) medium supplemented with 9.84 μM 6-(γ,γ-dimethylallylamino)purine (2iP) and 1.0 μM thidiazuron (TDZ). Maximum shoot multiplication rate [(8.2 ± 1.3) microshoots/explant)] was observed on this medium composition. Prior to rooting, the multiplied shoots were elongated for 60 days (two 30-days passages) on SH medium with one-half sucrose concentration, supplemented with 4.92 μM indole-3-butyric acid (IBA). The rooting of explants was only possible in the case of the elongated shoots. The highest root induction rate (54.8%) was achieved on solid SH medium with one-half sucrose and one-half potassium nitrate and ammonium nitrate concentration, respectively, supplemented with 28.54 μM indole-3-acetic acid (IAA) and 260.25 μM citric acid. The plantlets were acclimatized for 30 days in the glasshouse, with the use of peat/gravel/perlite substrate (1:1:1). The highest acclimatization rate (80%) was obtained for explants rooted with the use of IAA-supplemented medium. The phytochemical profile of the regenerated plants was similar to that of the reference intact plant material. HPLC analyses showed that C. genistoides plantlets obtained by the micropropagation procedure kept the ability to produce xanthones (mangiferin and isomangiferin) and the fl avanone hesperidin, characteristic of wild-growing shrubs.

<p>Micropropagation Efficiency of Banana cv Kepok<br />Amorang through Modifications of Culture Media and<br />Incubation Temperature. Yati Supriati. The budless<br />banana cv Kepok Amorang is potentially commercialized<br />due to its sweet taste and does not have flower bud, hence<br />reduced the potential of being infected by the blood disease<br />pathogen. Enhancement of banana industry needs continuous<br />supplies of large number banana seedlings. In vitro<br />culture enable the production of seedlings in a large scale,<br />uniform, quick. The research aims: (1) to formulate an<br />efficient medium for in vitro multiplication of cv Kepok<br />Amorang shoot, (2) to identify efficient growth environment<br />for in vitro culture of cv Kepok Amorang, and (3) to formulate<br />an efficient culture medium for roots inductions of cv<br />Kepok Amorang. The plant material used was in vitro culture<br />of Kepok cv Amorang, 2 cm in height without leaf and root.<br />The media formulation for shoot multiplication were full<br />strength, half strength, one fourth strength MS media,<br />supplemented with either 1, 3, or 5 ppm IBA. On optimization<br />step, the media tested were MS, Knop, Knop and<br />Heller, Hyponex N, Growmore N, and Rosasol N containing<br />of 1 ppm BA. The explants were incubated in culture room<br />with 8, 12, and 16 hours photoperiod with temperatures 30oC<br />(non air conditioned) and 25oC (air conditioned). The root<br />induction trial was done using MS, Knop, Knop and Heller,<br />Hyponex N, Growmore N, and Rosasol N media containing<br />of 1 ppm and 3 ppm IBA. The results showed that the best<br />medium formula for shoot multiplication was ¼ MS + 1 ppm<br />IBA. The best incubation condition was 16 hours photoperiods<br />at 30oC. The best media for root induction was<br />Hyponex 2 g/l + 1 ppm IBA. This culture method reduced<br />cost by Rp 261.7 per plantlet through efficiency of media<br />formulation and electricity use.</p>

The highest percentage (96.6) of multiple shoot induction and number of shoots (9.0) per culture were found on MS supplemented with 2.0 mg/l Kn. The induced shoots were excised and inoculated on to MS contains different concentrations of IBA or NAA for rooting. The highest percentage (90.0) of root induction and the highest number of roots per shoot (12.0) was found on MS having 1.0 mg/l IBA.

Physalis Angulata

Physalis angulata L. is an important medicinal herb. An efficient direct adventitious plant regeneration protocol was developed for large scale propagation using leaf disc as explants. The explants were cultured on MS basal medium supplemented with 0.25-3.0 mg/L 6-benzyl amino purine (BAP) for primary shoot proliferation. Inclusion of indole-3-acetic acid (IAA) and gibberellic acid (GA3) in the culture medium along with BAP promoted a higher rate of shoot multiplication. The maximum number of shoots was produced in MS + BAP (1.0 mg/L) + IAA (0.5 mg/L) + GA3 (0.20 mg/L) after the third subculture. An average of 152.8 ± 0.40 shoots were produced from each leaf disc. For root induction the shootlets were transferred to MS medium supplemented with different concentrations of indole-3-butyric acid (IBA). The highest percentage of root induction was observed in 1.0 mg/L (IBA). Rooted plants were successfully established in the soil after hardening. The survival percentage of rooted plants on soil was found to be 85%. This result will facilitate the conservation and propagation of the important medicinal herb Physalis angulata L.

Set Up

Papaya is a popular fruit and is grown commercially in many subtropical and tropical countries. Papayas are generally grown from seeds; therefore the offsprings are not true-to-type and could come in three sexes, female, male, and hermaphrodite. Clonal propagation is required to obtain to grow true-to-type hermaphrodite papayas. In this research, we developed an in vitro protocol for shoot multiplication from lateral shoots from in vitro germinated papaya seedlings. The in vitro propagated plant materials could potentially be used as a source of papaya micro cuttings, or as scion for papaya grafting. The experiment was set up as a factorial experiment with NAA at 0, 0.1 and 0.5 mg.L-1, and BAP at 0, 0.1, 0.5, and 1.0 mg.L-1 in a completely randomized block design. BAP interacted with NAA in affecting the shoot production per explant. The optimum BAP and NAA concentration to produce lateral shoots was 0.54 mg. L-1 and 0.1 mg.L-1, respectively. Media without NAA reduced the number of lateral shoots and number of leaf per explant at any BAP concentration.Keywords: hermaphrodite, seeds, true to type, clonal propagation, micro cuttings.
