Abstract

Vanda tricolor Lindl. var. suavis is an Indonesian wild orchid which is now extremely rare in nature due to its habitat destruction. Development of an appropriate method for propagation of this species through in vitro culture could be nessecary for conservation purposes. High phenolic content of plant tissue is a serious problem for V. tricolor research in the laboratory, which inhibits germination and growth of the embryo. To overcome this problem, seeds were sown in a medium with the addition of tomato extract as an antioxidant. The aim of this research is to find the most suitable concentration of tomato extract for germination and growth of the embryo of V. tricolor form Bali and Merapi in order to obtained healthy seedlings for conservation purposes. Orchid pods (7 months after polination) of V. tricolor Bali and Merapi were used as plant material. The treatment consisted of 5 concentrations of tomato extract which is 0, 50 100, 150, 200, 250 g L-1. Observation was done by counting the number of protocorms for each stage of growth at 4 weeks after seed sowing. The study concluded that V. tricolor Bali is more responsive to the tomato extract compared with Merapi. Concentration of 150 gL-1 tomato extract gave the highest percentage of protocorms for Bali form, whereas Merapi form did not give significant differences either with or without tomato extract added in the culture medium.

Abstract

Research concerning of propagation of a wild-extinct fern Lygodium circinnatum had been done at Faculty of Agriculture, Udayana University, Denpasar Bali Indonesia. At some places in Indonesia, as well as Bali, this species is used as materials for making handicraft. In Bali, the species grows wildly in the forest and it is almost extinct due to over gathering. This study aimed to find out method for domestication of L. circinnatum, therefore this wild species can be cultivated, provided materials for making handicraft and might solve the problem of extinction. Various media for growing spores of L. circinnatum in vitro and ex vitro were trialed. In conclusion, full strength of MS media without sugar was the most appropriate media for growth and development of spores of L. circinnatum in vitro. While for ex vitro, the appropriate media were paddy silt-soil and decomposed leaf either with or without addition of foliar fertilizer. However, we suggested ex-vitro cultivation was more appropriate, the technique was much easier and the spores grew faster compared to those of in-vitro.

Abstract

Propagule Induction of Node Culture of Grape (Vitis vinifera) varieties Prabu Bestari at Various Concentration of BA and NAA Propagation of grape seeds still uses conventional methods such as cuttings and grafting. In vitro culture technology can be a solution for plant propagation techniques that using small explants and in small quantities but capable to producing large amounts of seeds. Propagules are new formations that arise from explant tissue, can be in the form of shoots or callus that can occur through direct or indirect organogenesis. The aim of the research was to obtain the best culture medium in the formation of propagules. The research was conducted in two stages, the first was propagule induction and the second was subculture. The research used a Completely Randomized Design. Propagule induction was used a factor with combination of BA and NAA. The levels use of ZPT BA are: 2 ppm, 4 ppm, 6 ppm and the levels use of ZPT NAA are: 1 ppm, 3 ppm, and 5 ppm. The total combination treatment was 9 treatments and the addition of treatment K0 (control). Each treatment was repeated 3 times for a total of 30 experimental units. The subculture medium used was WPM + 1 ppm TDZ. The results showed that MS treatment with a combination of ZPT BA and NAA succeeded in forming propagules in the form of meristemoids and shoots. K3 (MS + 2 ppm BA + 5 ppm NAA) was the treatment that gave the best response to the percentage of meristemoid formation of 100%. K4 (MS + 4 ppm BA + 1 ppm NAA) was the treatment that succeeded in inducing 33.3% shoots.

Abstract

Fertilization outside the season of Siam Orange (Citrus microcarpa L.) with Induction of Flowering and Dormancy Breaking Substances. The Siam orange (Citrus microcarpa L.) produces seasonal fruit with the on-season harvest from July to August while the off-season harvest, i.e. from February to September there is hardly any fruit, or very limited supply. The purpose of this study was to examine the response of flowering induction and dormancy-breaking substances to produce off-season fruits of Siam orange. This research began in April to December 2016. The experiment was arranged factorially with two factors using a randomized block design (RBD), with nine combination treatments and six replications. Flowering induction factors consist of three levels, namely Ik = Control, IP = Paclobutrazol at a dose of 7.5 g/l, and Im = cutting the tip of dormant twigs. Dormancy-breaking substances factor consists of three levels, namely Dk = Control, Db = BAP 200 ppm, and Dn = KNO3 300 ppm. The results of the experiment showed that the highest fruit weight per tree at off-season production was obtained by induction with paklobutrazol (28.86 kg) and the lowest was in control (12.75 kg). Flowering induction treatments was not significantly different effect on fruit quality of Siam orange, represented by weight per fruits, fruit diemater, total soluble solid and vitamine C content was not siginificant different among levels of treatment. Dormancy-breaking substances treatment also not significantly effect on fruit quality of Siam orange. Based on this research it is recommended to induce flower for off-season produce of Siam orange by pruning the tips of dormant twigs or by using paklobutrzol.
