Background: Rooting of pineapple from Sipahutar in vitro is an alternative to obtain superior seeds in large quantities to meet the needs of farmers and consumers.Objective: The purpose of this study was to investigate the effect of Myo-inositol and IBA on pineapple rooting (Ananas comosus L.) from Sipahutar in vitro.Methods: The research method used a completely randomized factorial design with two factors: Factor I: Myo-inositol consisted of [4] treatment concentrations: M0 = 0 g/l, M0.02 = 0.02 g/l, M0.04 = 0.04 gr/l, M0.06 = 0.06 gr/l. Factor II: IBA growth regulators consisted of [3] treatment concentrations: IB0 = 0 ppm, IB1.5 = 1.5 ppm, IB3 = 3 ppm. The parameters observed were time of root emergence, number of roots, number of leaves, time of leaf emergence, number of tillers, and time of its emergence observed each week, while the height of tillers, shoots, and whole shoots, root length, leaf width and leaf length were observed 12 weeks after planting (WAP).Results: The result of the research showed that root time appeared on [3] WAP. The increasing number of leaves and timing of the puppiesin 1 WAP. Myo-inositol had significant effects on root counts in the 0.06 gr/l and root length on Myo-inositol treatment in the 0.04 g/l. IBA did not have a real effect on the entire observation parameters. The interactions of Myo-inositol and IBA had significant effects on root number, number of leaves, leaf length and tiller height.Conclusions: Myo-inositol and IBA had significant effects on root number, leaf number, leaf length and shoot height of pineapple’s explant from Sipahutar.

In vitro cultivation is a highly important biotechnological method widely used for the production of orchid seedlings, but it is necessary to study the suitability of the nutrients used in different kinds of formulation, as the nutritional requirement varies according to the species. The objective was to evaluate different concentrations of iron in the in vitro cultivation of Schomburgkia crispa Lindl seedlings. Seedlings were obtained from seeds germinated in vitro. Modified MS culture medium was used with half of the macronutrient concentration. The micronutrients were added according to the original formulation, except for the iron which was added from a stock solution of FeEDTA (FeSO4.7H2O: 5.6 g L-1 and EDTA: 7.48 g L-1) at 0.0; 2.5; 5.0; 7.5; 10.0 and 12.5mL L-1. At 200 days after seedling transplantation, shoot height, root length, number of leaves, shoot number, leaf length, leaf width, aerial and root dry mass, chlorophyll a, b and carotenoids content were evaluated. A completely randomized design was used, with six treatments and ten replicates of five seedlings. Regression analysis was performed at 5% of significance. The increase in iron concentration caused a reduction in root length and an increase in the number of leaves and shoots. The concentration of 4.13 mL L-1 of FeEDTA was the one that provided the best in vitro growth of S. crispa plants. High concentrations of iron caused a reduction of initial development, but stimulated an increase in the number of shoots.

The use of foliar fertilizers and coconut water is potential; foliar fertilizer is the alternative medium and coconut water is the plant growth regulator (PGR) in the banana tissue culture. This study aimed to examine the ability of foliar fertilizer to substitute Murashige and Skoog (MS) media and coconut water as the main source of cytokine. There are two factors in this research. The first factor is the media, which consist of three levels, i.e. fully MS, ½ MS + ½ foliar fertilizer and fully foliar fertilizer. The second factor is the coconut water with four levels of concentration i.e. 50, 100, 150 and 200 ml l<sup>-1</sup>. The results show that fully formulated foliar fertilizer had not been able to substitute or even compete with a fully MS media, but conversely foliar fertilizer was used to substitute ½ MS media. This can be seen from the parameters of shoot length, leaf length, root number and root length with the highest yield that was found in MS media (8.7, 4.66, 3.33 and 3.23 cm). The 50-100 ml l<sup>-1 </sup>concentrations of coconut water showed the best results by giving a significant effect on the number of roots and root length. The acclimatization of plantlets in this study was nearly 100%, indicated by the formation of a complete organ.

To improve the growth of Grammatophyllum scriptum (Lindl.) Bl. in vitro plantlet, a photoautotrophic micropropagation system (PMS) was developed by growing in vitro plantlet on VW medium with varying concentration of sucrose (0, 5, 10, and 20 g/L) and additional carbon dioxide from the air (bottle covered with cap or filter). The result showed that the leaf length would increase up to 6.5 cm with PMS and it would keep growing by the adding of 5 g/L sucrose. Average number of leaves increased by 6.7 strands with PMS and the addition of sucrose increased the average quantity of leaves up to 7.7 strands. Average number and root length would increase with PMS and would even increase more with 5 g/L sucrose addition. PMS with 5 g/L sucrose can increase chlorophyll a and b concentration. The number of stomata per unit area in PMS was lower than closed culture. This shows that PMS can increase the growth of G. scriptum in vitro plantlet and the growth increase would be effective if it is combined with sucrose addition.
