Rauwolfia serpentine [L] Kurz ex Benth is a valuable plant yielding alkaloid of reserpine. The aim of this study was to find the most effective way of reserpine production. Growth regulators {naphthalene acetic acid [NAA] and Kinetin}were applied to promote and to regulate the growth of explant of R. serpentine cultured in vitro. The study was conducted at the laboratory of Bandung Institute of Technology [ITB]. Nine formulations of NAA and Kinetin were the treatments that were repeated twice in completely randomized design. Weight of callus was measured at one, two, three and four weeks after induction of explant. Reserpine analysis was performed by High Performance Liquid Chromatography [HPLC]. The result showed that the best callus induction was the treatment of 2.5 ppm NAA + 2.5 ppm Kinetin, and the highest content of reserpine was in root organ [0.0021 g / L], and in callus [0.0021 g / L] at the age of 4 weeks after induction. There was revealed that in vitro culture method was more productive in producing reserpine compound than the conventional plantation of R serpentine.  Production of reserpine by callus culture was more effective and may be the basic for recommended further effort.

Conventionally, cultivations of Nepenthes are conducted by using seeds, cutting, and filial separation. However, there are many obstacles come both from time and technical aspect. In vitro culture is an alternative way for cultivating  N. ampullaria (Jack,). One of a technique of in vitro culture is micro cutting. BAP (6-benzyl amino purine) growth regulator could be added to optimize the growth of  N. ampullaria microcutting. The purpose of this research was to determine the effect of  BAP on the growth of Nepenthes microcutting. This research was done experimentally using Completely Randomized Design (CRD). BAP treatment consisted of 5 concentrations: 0; 0.5; 1; 1.5; 2 (ppm), each treatment were multiplied 4 times. The parameters observed were: a time of bud initiation, time of root initiation, total of leaves, total of new buds, total of roots, length of leave, length of root, and height of bud. The data obtained were analyzed with ANOVA (Analisis of Variance) and continued with 5% and 1% LSD (Least Significant Different)  test. The result showed that addition of BAP affected the growth of  N. ampullaria microcutting in total leaves, length of leave, and total of buds. LSD test proved that 0.57 ppm of BAP was optimal concentration to increase total buds, whit the value reached of 3.86. Here, we found that BAP can be utilized to enhanche N. ampullaria growth on in vitro culture. The benefit of this study is to conserve N. ampullaria in vitro using BAP at  0.57 ppm.

ABSTRACT Wild piquin pepper fruits are consumed and traded because of their flavor, nutritional and pharmaceutical properties. The heterogeneous germination of its seeds has caused pregermination treatments to be unstandardized. Because of that, our goal was to evaluate pregermination treatments of piquin pepper seeds from a wild plant from the municipality of Victoria, Tamaulipas, Mexico, consisting of immersion for different periods (2, 24, 48 h) in solutions with variable concentrations of the growth regulators naphthalene acetic acid (NAA; 0.1, 1.0, 2.5 mM), salicylic acid (SA; 1.0, 5.0, 10 mM), gibberellic acid (GA3, 1.0, 5.0, 10 mM), indole-3-butyric acid (IBA; 1.0, 2.0, 3.0 mM), the commercial product Biozyme (Bioz) containing minerals and growth regulators (Bioz; 0.5, 1, 2%), and sulfuric acid (H2SO4; 2, 5, 10%) in a completely randomized design, using distilled water as the control. For each treatment, we measured the imbibition ratio, germination percentage, time to obtain 50% germination (T50), and coefficient of variation of germination time (CVt). Our results showed that the imbibition was similar in the control and the treatments, but it differed between treatments. The highest imbibition recorded in 48 h was 87%. The highest germination percentage (79.2%) was achieved with 2 h immersion in 2% Bioz, followed by 1 mM NAA (62%) and 5 mM SA (56%). T50 and CVt were 10-26 d and 0-39%, respectively. According to our results, we concluded that the pregermination treatments we assayed improved the physiological potential for the germination of piquin pepper seeds.

Mangosteen is considered as fruit of many benefits with great popularity, rendering it valuable as an export commodity. Unfortunately, it has a relatively slow growth  and long early fruiting time. Generative propagation of mangosteen by seed result in low-yielding productionof qualified seedswith recalcitrant nature which means it cannot be stored for a long time. Whereas the result of vegetative propagation using grafting, branch cuttings and budding has difficulty rooting out. Tissue culture method requires growth regulators to control organogenesis and morphogenesis so it can accelerate the growth of the mangosteen explants. This study was arrangedintwo- factor completely randomized design (CRD). The observed variables werethe strength of the medium (½ and 1 MS) and GA3 concentrations (0 ppm; 0.25 ppm; 0.5 ppm; 0.75 ppm and 1 ppm). The variatonson GA3 concentration (0 ppm; 0.25 ppm; 0.5 ppm; 0.75 ppm; 1 ppm) on  different strength MS medium (½ MS and 1 MS) did not significantly affect the growth of radicle and sooth in the  in vitro seeds germination of Mangosteen (Garcinia mangostana).
