The more common methode for planting moringa plant is using seed, because this plant produces a lot of seeds. However, the resulting seeds have a hard enaugh seed coat so that. These conditions can affect and even thwart germination, vigor and growth of the plant. This Study aims to determine the proper dosage of young coconut water to be used in growing moringa seeds, so that later it become a recommendation for formers in the development of moringa plants. This research was conducted using a green house and laboratory scale method with the media that had been prepared for germination obsevations were carried out for two weeks to obtain data according to the observed parameters which included capacity, Vigority and dryweight of moringa plants. The result of the analysis of variety showed that the concentration of young coconut water had no significant effect (P>0.05) on the germination, vigor and dryweight of moringa plants. Likewise, the interaction between immersion time and coconut water concentration had no significant effect (P>0.05) on the observed variables. This situation is due to the fact that not all moringa seeds undergo the imbibition process properly so that they effect the observed variables.

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.

The purpose of this research is to determine the concentration of young coconut water that is appropriate for the growth of orchid plantlets (Dendrobium sp.) In vitro. This study used an experimental method, descriptive data analysis to compare several different concentrations of coconut water. The design of this study uses a completely randomized design (CRD). The treatments consist of 0% coconut water concentration (as a control), 15%, 30% and 60%. Each concentration was carried out 5 replications and each repetition consisted of 5 Dendrobium sp plantlets in each culture bottle conducted for 40 HST, for observing the root length carried out for 50 HST. The highest number of shoots and leaves were produced at the same concentration, namely 150 ml / L coconut water treatment (15% concentration) with an average of 2.8 shoots and the average number of leaves 10.8 leaves. The average number of roots and the longest root length was produced at a concentration of 600 ml / L coconut water (60% concentration) with an average of 6 roots, and the longest root length was 0.5 cm.Keywords: Young coconut water, (Cocos nucifera L.), Dendrobium sp., in vitro, growth.ABSTRAKTujuan penelitian ini ialah menentukan konsentrasi air kelapa muda yang tepat untuk pertumbuhan planlet anggrek (Dendrobium sp.) secara in vitro.

The study was undertaken with a view to investigate the effects of different basal media and organic extracts on organogenesis of Dendrobium orchid. Protocorm like bodies (PLBs) were cultured in Knudson C (KC), Vacin and Went (VW), half strength Murashige and Skoog (½MS) and New Phalaenopsis (NP) media supplemented with Sabri banana pulp (Sb), Charcoal (C) and Coconut water (Cw) organic extracts. KC, VW, ½MS and NP media significantly influenced the plantlet regeneration of Dendrobium orchid. Among the media, ½MS showed better performance on fresh weight, number PLBs, shoots and leaves per plantlet, The longest shoots were found in KC medium and maximum length of leaves was found in both KC and ½MS media. In case of different organic extracts Sb showed significantly better performance on fresh weights of PLBs, number of shoot and leaves per explant, length of shoots and leaves.

Seed coat impermeability to water occurs in many species, including Schizolobium amazonicum Huber ex Ducke. To promote germination in seeds with coat impermeability the use of sulphuric acid (H2SO4) is recommended. The objective of this study was to identify a better time for the scarification with sulphuric acid for S. amazonicum seeds. The effect of scarification with sulphuric acid for 20, 40 and 60 min on germination and speed germination was studied for seeds that were either sowed immediately after scarification or after a 24-hour period of immersion in water. Seeds were sown on a mix of sand and sawdust (1:1). The experimental design was completely randomized with four replications of 50 seeds. The statistical analysis of germination was carried out at six, nine, 12, 15, 18, 21 and 24 days after sowing, in a factorial scheme. For speed germination the means were compared by the Tukey test. There was an interaction between treatments to overcome dormancy and immersion time after scarification in most evaluations. Immersion in water accelerated the beginning of germination. All treatments to overcome dormancy promoted seed germination. However, scarification for 60 min, showed better germination, 92% when immediately sown and 86.5% when sown after 24 hours. Speed germination index was highest for scarified seeds for 60 min followed by immersion in water. Scarification for 60 min was the most efficient treatment to promote germination in S. amazonicum seeds.

Chryssanthenum is ornamental plant with variety of shape and color which are unique and appealing. So that, it is in great demand in the community. The production of Chrissanthenum conventionally hampered by availability and quality of seeds. Thus, it needs research through tissue culture. The aim of this research is to know interaction between coconut water and thiamine and to determine the best coconut water and thiamine concentration toward Chryssanthenum micro cuttings. This research used laboratory experimental method by using completely randomized design with two factor. The 1st factor was coconut water concentration consisted of three level which were 5%, 10% and 15%. The 2nd factor was thiamine concentration consisted of three level which were 1mg/L, 2 mg/L and 3 mg/L. From the two factors, those were found that, there were nine combination of treatments and repeated 3 times. The variety  of data was analyzed by using Analysis of Variance (ANOVA) with level of α=5%, and continued by examining Duncan’s Multiple Range Test (DMRT) with level of α=5%. The result indicated that the interaction of coconut water concentration was 5% and thiamine was 1 mg/L on the parameters when growing shoot. There was also interaction on coconut water concentration which was 10 % and thiamine was 1 mg/L on the parameters in the number of shoots. interaction of coconut water combination was 15% and thiamine was 2 mg/L on  fresh weight. The addition of 10% coconut water and 1 mg/L thiamine showed the best result on shoot length.

Abstract In this study, several concentrations of benzyl amino purine (BAP) and coconut water (CW) were investigated along with the interaction between two factors to the growth of in vitro propagated fig shoots. The investigated factors consisted of BAP concentration: 0, 1, 3, 5 mg L−1 and coconut water concentration: 0, 100, 200, 300 ml L−1. A total of 16 treatment combinations with 6 replications resulting in 96 experimental units consisting of a single fig shoot explant per culture medium. The observed parameters including living explant rate, contamination rate, browning rate, day of first shoot emergence, shoot formation rate, explant height addition, number of leaves, callus formation rate, and number of roots were conducted every week from 1 to 8 weeks after proliferation (WAP). The result indicated that in 8 WAP, the living explant rate reached 23.95%. The combination of concentration 200 ml L−1 CW and 3 mg L−1 BAP + 200 ml L−1 CW-induced early emergence of new shoots at 7 days after proliferation (DAP). The highest shoot formation rate (100%) was observed at a concentration of 300 mL L−1CW. The highest explant height addition (7.10 cm) was observed at a concentration of 200 mL L−1 CW. The highest number of leaves (5.80) was observed at a concentration of 1 mg L−1 BAP + 200 mL L−1 CW. The highest callus formation rate (50%) was observed at a concentration of 100 ml L−1CW and 300 ml L−1 CW. The highest number of roots (17) was observed in the control.
