An efficient protocol was established for in vitro shoot multiplication of the biodiesel plant, Jatropha curcas L. (Euphorbiaceae) through direct organogenesis using shoot tip and nodal explants. Best shoot induction was observed on MS basal medium supplemented with 1.5 mg/l BAP + 0.5 mg/l NAA, in which 86.2% of nodal explants responded to produce maximum number (7.2 ± 0.68) of shoots per culture. In vitro raised shoots rooted on half strength MS medium with 1.0 mg/l IAA. The survival rate of regenerated plantlets was 85%. DOI: http://dx.doi.org/10.3329/bjsir.v49i1.18854 Bangladesh J. Sci.

The effects of four types of explants removed from 10-cm flower stalks of Doritaenopsis Purple Gem ‘Ching Hua’ (immature apical flower buds, immature lateral flower buds, flower stem nodes, and flower pedicel sections) and combinations of two plant growth regulators [naphthalene acetic acid (NAA) and thidiazuron (TDZ)] on direct in-vitro shoot induction and multiplication were studied. Immature apical flower buds were the only explants that showed induction and multiplication of shoots in vitro. NAA at 5.4 and 10.7 μm combined with either 4.5 or 9.1 μm TDZ provided the fastest and greatest percentages of shoot induction (27% to 40%) and the greatest numbers of shoot multiplication (111–160 shoots per explant). In vitro–induced shoots were rooted on medium containing 5.4 μm NAA and developed into plantlets with normal vegetative and reproductive morphology. Regenerated plantlets were acclimatized, showing 100% survival and establishment in greenhouse. Plantlets were grown to maturity and showed normal flower morphology. No floral off-types were observed. The high rates of shoot multiplication obtained offer a means for mass clonal propagation of this and possibly other related Doritaenopsis hybrids.

Andalehis the local name of  MorusmacrouraMiq. in West Sumatra, Indonesia. Nowadays, this dioeciously speciesis in endangered situation. The aim of the research is to find out the appropriate combination of plant growth regulator to induce shoot multiplication of explants from male and female trees of andaleh. The plantlets from this research will be used in the next future to conserve this endangered species in vitro and in vivo, especially in preparing parental material in breeding program. Young buds from male and female trees were used as an explants in basal medium Murashige and Skoog supplemented with BAP (0.5, 1.0, 1.5 and 2.0 mg.L-1) in combination with NAA (1.0 mg.L-1 for each).  The frequency of bud break was 50 % in MS medium supplemented with BAP (0.5 mg.L-1) and NAA 1.0 mg.L-1 for both source of explants (female and female trees of andaleh) after 3 weeks of culture. Generally, the number of shoot induction was very low. On the other hand, the rate of callus formation was high (100%) in highest BAP concentration (2.0 mg.L-1).

In vitro culture is a promising technique for mass propagation of high-value species. Study of propagation for Acacia hybrid (A. mangium x A. auriculiformis) through this technique has been conducted using single node stem from seedlings as explants. Growth medium used was modified Murashige and Skoog (MS), basal medium Woody Plant Medium (WPM), and Gamborg (B5) supplemented. The study was conducted in two stages, namely shoot induction and shoot multiplication. The treatment tested was the Benzyl Adenine (BA) supplementation at the concentration of 0.3; 0.7; and 1.0 mgL-1 of. Observation was conducted on the frequency of shoot induction, number of shoot, shoot length and visual performance of the culture. The result showed that treatment of BA 0.7 mgL-1 on modified MS medium is the best for shoot induction, shoot multiplication and visual performace of the culture. The average of number of shoot was 2.6; 5.0 and 7.7 shoots on the first three consecutive subcultures. Changing to different basal medium on the fourth subculture showed that the treatment of BA 0.7 mgl-1 is the best condition for shoot regeneration (12.60 shoots) and shoot length (6.97 cm). The culture from this treatment showed the best visual morphological performance.Keywords:Acacia hybrid; multiplication; subculture; in vitro; BA. ABSTRAKKultur in vitro merupakan suatu teknik yang menjanjikan untuk perbanyakan massal spesies-tanaman bernilai tinggi. Penelitian perbanyakan akasia hibrid (A. mangium x A. auriculiformis) melalui kulturin vitro telah dilakukan dengan menggunakan eksplan berupa batang satu buku yang berasal dari anakan. Media tumbuh yang digunakan adalah media dasar Murashige dan Skoog (MS) yang sudah dimodifikasi, media dasar Woody Plant Medium (WPM), dan Gamborg (B5). Penelitian dilakukan dalam dua tahap yaitu induksi tunas dan perbanyakan tunas. Perlakuan yang diuji adalah penggunaan Benzyl Adenine (BA) dengan konsentrasi 0,3; 0,7 dan 1,0 mg L-1. Pengamatan dilakukan terhadap waktu induksi tunas, jumlah tunas, tinggi tunas dan penampilan biakan secara visual. Hasil penelitian menunjukkan bahwa penggunaan BA 0,7 mg L-1 pada media MS modifikasi merupakan perlakuan terbaik untuk induksi tunas, perbanyakan tunas, tinggi tunas, dan kondisi biakan secara visual. Jumlah rata-rata tunas yang dihasilkan dari perlakuan ini adalah 2,6; 5,0 dan 7,7 tunas pada subkultur pertama, kedua dan ketiga. Pada penggunaan media dasar berbeda pada subkultur keempat menunjukkan bahwa perlakuan BA 0,7 mg L-1 merupakan perlakuan terbaik dengan jumlah tunas sebanyak 12,60 tunas dan rata-rata tinggi tunas 6,97 cm. Biakan yang dihasilkan dari perlakuan tersebut mempunyai penampilan yang baik dan normal.
