An alternative protocol for in vitro propagation of Picrorhiza scrophulariiflora is described using bavistin and adenine sulphate. The explants differentiated into multiple shoot buds on MS supplemented with various concentrations of bavistin and adenine sulphate ranging from 0 - 400 mg/l either alone or in combination. Maximum number of multiple shoots were obtained on MS containing the combination of bavistin (100 mg/l) and adenine sulphate (100 mg/l). In this combination as high as 28 shoots per explant was achieved and also vetrification of the cultures were not recorded. This study also demonstrates that the bavistin has stronger cytokinin-like activity than adenine sulphate. For instance, it was observed that bavistin alone in the concentration of 300 mg/l produced as high as 24 shoots per explant, however, adenine sulphate (100 mg/l) could produce a maximum of 18 shoots per explant. Moreover, higher or lower concentration did not improve the shoot multiplication. The microshoots were separated from the multiple shoots and transferred to MS containing various concentrations of auxins. Among them, NAA (1 mg/l) produced as high as 6 roots per explant. The regenerated plantlets were hardened in plastic cups (6 x 8 cm) containing 9 : 1 virgin soil and soil at Kyongnosla nursery and acclimated for four weeks. A 90% survival rate of the plants was recorded after 60 days. D.O.I. 10.3329/ptcb.v19i2.5441 Plant Tissue Cult. & Biotech. 19(2): 237-245, 2009 (December)

Effect of Thidiazuron and Casein Hydrolysate on In Vitro Shoot Multiplication of Satoimo (Colocasia esculenta (L.) Schott var antiquorum)ABTRACTSatoimo (Colocasia esculenta (L.) Schott var antiquorum) is an alternative substitute of rice which has a big potential to be developed in Indonesia as an export commodity to Japan. Satoimo production needs to be increased to meet the demands for of the plant seeds. Plant propagation can be done using optimal media to stimulate the formation of shoots through, amongst others, the addition of thidiazuron (TDZ) and casein hydrolysate into the culture medium. This study aimed to determine the optimal concentration of TDZ and casein hydrolysate for in vitro multiplication of satoimo shoots. This research used RAL method with 2 factorials, namely the addition of TDZ at 0; 0.2; 0.6 mg/L concentrations, and of casein hydrolysate at 0; 150; 300; 450 mg/L concentrations. The results showed that the use of 0.6 mg/L TDZ and 150 mg/L casein hydrolysate resulted in the highest number of shoots, with the shoot average number of 6.9 per explant.Keywords: Casein hydrolysate, optimal medium, Satoimo, shoot multiplication, TDZ  ABTRAKSatoimo (Colocasia esculenta (L.)

In Vitro Propagation of Kepok Banana var. Unti Sayang Resistant to Blood Disease through Shoot ProliferationABSTRACTKepok is a popular banana variety but sensitive to blood disease caused by Ralstonia solanacearum (Smith). The discovery of a natural mutant of Kepok banana var. Unti Sayang from Sulawesi which male bud falls naturally, is a shortcut to bypass the chains of the spread of blood disease, since the disease is transmitted by insects through the wounds of the male buds. The superior mutant needs to be mass propagated and disseminated to endemic areas to inhibit the spread of blood disease. To achieve that goal, an efficient and effective techniques of in vitro shoot proliferation needs to be developed. Shoot proliferation was performed by addition of BAP, thidiazuron and adenine sulphate. The results showed that the best medium for shoot multiplication was B2T5A (MS+2 mg/L BAP+0,5 mg/L TDZ+20 mg/L adenine sulphate), and for shoot growth was B4A (MS+4 mg/L BAP+20 mg/L adenine sulphate). Rooting was induced on MS medium without hormones. Acclimatization of plantlets on mixed soil, compost and husks with a ratio of 1:1:1 resulted in 92,35% survival rate.Keywords: blood disease, in vitro shoot,  male budless, natural mutant, var. Unti Sayang  ABSTRAKPisang kepok merupakan varietas yang digemari tetapi sangat peka terhadap penyakit darah yang ditimbulkan oleh bakteri Ralstonia solanacearum (Smith).

In the present experiment an attempt has been made to optimize the effect of different medium, levels of sucrose, pH, adenine sulphate and light intensity for culture establishment and shoot proliferation in guava using nodal segment explants. Culture establishment was greatly influenced by media types. Maximum establishment ofexplants (74.57%) was recorded on MS medium supplemented with 2.0 mg/l BAP + 0.2 mg/l IBA. In proliferation study, the maximum shoot proliferation was observed in MS + 1 mg/l BAP + 0.25 mg/l GA3. Sucrose 3% was found to be more favorable for maximum proliferation and growth of shoots moreover, it was reduced gradually as increased or decreased levels of sucrose from 30 g/l. among the various pH levels tested, pH 5.5 recorded maximum number of shoots (8.08) and maximum length of shoots (3.75 cm).In proliferation medium the length of shoot, numbers of shoots and growth rate were increased as increased the adenine sulphate level in the medium. Maximum proliferation was observed on 160 mg/l adenine sulphate in the medium. High light intensity 3000 lux was found to be most suitable for proper growth of regenerated shoots. Low light intensity (1000 lux) resulted in stunted growth. All the above factors significantly influenced shoot multiplication and growth. Thus, optimization of these factors showed significantly increased number of shoots and rapid multiplication. This could be useful for the in vitro production of cost effective healthy planting material of guava

This study aims to investigate whether the in vitro-cultured L. pumila var. alata has higher antioxidant activity than its wild plant. An 8-week-old L. pumila var. alata nodal segment and leaf explants were cultured onto Murashige and Skoog (MS) medium supplemented with various cytokinins (zeatin, kinetin, and 6-benzylaminopurine (BAP)) for shoot multiplication and auxins (2,4-dichlorophenoxyacetic acid (2,4-D) and picloram) for callus induction, respectively. The results showed that 2 mg/L zeatin produced the optimal results for shoot and leaf development, and 0.5 mg/L 2,4-D produced the highest callus induction results (60%). After this, 0.5 mg/L 2,4-D was combined with 0.25 mg/L cytokinins and supplemented to the MS medium. The optimal results for callus induction (100%) with yellowish to greenish and compact texture were obtained using 0.5 mg/L 2,4-D combined with 0.25 mg/L zeatin. Leaves obtained from in vitro plantlets and wild plants as well as callus were extracted and analyzed for their antioxidant activities (DPPH and FRAP methods) and polyphenolic properties (total flavonoid and total phenolic content). When compared with leaf extracts of in vitro plantlets and wild plants of L. pumila var. alata, the callus extract displayed significantly higher antioxidant activities and total phenolic and flavonoid content. Hence, callus culture potentially can be adapted for antioxidant and polyphenolic production to satisfy pharmaceutical and nutraceutical needs while conserving wild L. pumila var. alata.

The use ofin vitroculture has been accepted as an efficient technique for clonal propagation of many woody plants. In the present research, we report the results of a number of experiments aimed at optimizing micropropagation protocol for tea (Camellia sinensis(L.) O. Kuntze) (clone Iran 100) using nodal segments as the explant. The effect of different combinations and concentrations of plant growth regulators (PGR) (BAP, TDZ, GA3) on shoot multiplication and elongation was assessed. The influence of exposure to IBA in liquid form prior to transfer to solid media on rooting of tea microshoots was investigated. The results of this study showed that the best treatment for nodal segment multiplication in terms of the number of shoot per explant and shoot elongation was obtained using 3 mg/L BAP in combination with 0.5 mg/L GA3. TDZ was found to be inappropriate for multiplication of tea clone Iran 100 as it resulted in hyperhydricity especially at concentrations higher than 0.05 mg/L. Healthy shoots treated with 300 mg/L IBA for 30 min followed by transfer to 1/2 strength MS medium devoid of PGR resulted in 72.3% of shoots producing roots and upon transferring them to acclimatization chamber 65% survival was obtained prior to field transfer.
