<p>Propagation through tissue culture of plant<br />species with rich secondary metabolites such as Jatropha<br />curcas L. is difficult to obtain. However, once established, it<br />can be used as one of the alternatives to supply uniform<br />propagules. The effects of auxin and cytokinin on the<br />regulation of de novo woody plants shoot development have<br />been studied through shoot induction, differentiation and<br />development. The objective of this research was to identify<br />explant and suitable culture media for in vitro shoot induction<br />through indirect organogenesis. Factorial experiment<br />was arranged in a completely randomized design, replicated<br />20 times. The first factor was explants, i.e. cotyledons and<br />hypocotyls. The second factor was MS media containing<br />combination of plant growth regulator IAA (0, 0.05, and 0.1<br />mg/l) and BAP (0, 1.0, 2.0, 3.0 mg/l). The results of the<br />experiment showed that the fastest callus initiation was<br />achieved by MS + IAA 0.1 mg/l, i.e. 9.5 days after explants<br />were cultured. Shoots with leaves can be induced from both<br />cotyledons and hypocotyls. However, hypocotyls gave more<br />shoots and leaves than cotyledons when cultured in MS +<br />IAA 0.1 mg/l + BAP 3.0 mg/l. Shoots obtain from hypocotyls<br />and cotyledons were successfully rooted in MS medium<br />without any growth regulator.</p>

Dendrobium anosmum is one of natural orchids in Indonesia. Optimization of medium composition for orchid propagation through in vitro culture is necessary to enhance propagule multiplication capabilities and quality. This study was aimed to study the influence of concentration of coconut water in culture medium on in vitro growth and development of D. anosmum orchid species and to determine the optimal coconut water concentration in culture media.  The experiment were arranged in a Completely Randomized Design with four treatments and eight replications. The treatments consisted of the addition of coconut water with concentrations: 0 ml•l -1 (control), 50 ml•l-1, 100 ml•l-1 and 150 ml•l-1. The results showed that addition of coconut water in culture medium gave different effect on shoot growth and multiplication of D. anosmum orchids.  Coconut water concentration of 100 ml•l-1 was the best concentration for growth and multiplication of D. anosmum orchids, based on both shoots and roots growth, plantlet height and wet weight.

In olive, micro-propagation is an effective technique for mass multiplication of disease free, true to type plants, but shoot proliferation in mature tissues of olive is a major difficulty encountered during culture establishment. Thus an experiment was designed with an objective to study the effect of different cytokinins (BAP and Zeatin) on shoot proliferation of two olive cultivars (Earlik and BARI Zaitoon-2). In olive Rugini medium, BAP and Zeatin were added alone and in combination at a concentration of 1 mg L-1 and 2 mg L-1. Experiments were arranged according to completely randomized design (CRD) with three replications per treatment. Results showed that both the olive cultivars performed well when BAP + Zeatin were supplemented to the medium at 2+2 mg L-1 concentration. However, the cultivar “BARI Zaitoon-2” had the highest shooting percentage (90.67 %) and number of nodes per shoot (8.33) in treatment containing BAP (2 mg L-1) + Zeatin (2 mg L-1), whereas, “Earlik” at same concentration had more shoot length (9.10 cm) and number of shoots per explant (3.67). Thus, it was concluded that the findings of these results will help in the future for developing shoot proliferation protocols for other olive cultivars. Moreover, these protocols can also be further be used in other woody plants micro propagation

ABSTRACT: The objective of this paper was to evaluate the effects of different honey concentrations in culture media, in comparison to sucrose medium, for the in vitro development of the epiphytic Encyclea cordigera orchid, in order to improve the process of propagation of the species. The in vitro germination was prepared on a reduced Murashige & Skoog (MS) medium. After 90 days, the seedlings were divided into different treatments, where they remained for another 90 days. Six treatments were set up (30g L-1 of sucrose; 15, 30, 45, and 60g L-1 of honey; and absence of any carbohydrates) in a completely randomized design. Plants were removed from the vials 270 days after the start of the experiment, and the number of roots, length of the largest leaf, length of the longest root, number of leaves, and fresh and dry masses were evaluated. Data concerning the number of leaves and roots were (x+1)1/2 transformed and subjected to an analysis of variance (ANOVA); the means were compared by a Tukey's test set at 5% probability. Medium containing 60g L-1 of honey proved to be superior to the sucrose medium traditionally used, favoring the in vitro growth and development of Encyclea cordigera. This medium can therefore be recommended for the propagation of this species, which is usually cultivated as an ornamental plant.
