Abstract

Study of Differences in Entres Saving Media on the Success of Grafting Wani Ngumpen Bali (Mangifera caesia Jack.Var. Ngumpen Bali) Wani (Mangifera caesia Jack.) is a local fruit plant that has a fairly high diversity of 22 cultivars in all wani production centers in Bali. One of the cultivars, namely Wani Ngumpen Bali, has the advantage of producing fruit that does not contain seeds as much as 90% of the total fruit. Due to constraints in generative seed production, wani are propagated vegetatively by means of grafting. Due to the limited time and the number of grafted seedlings, efforts are needed to maintain the freshness of the shoots through storage. The purpose of this study was to determine the best entres storage media for female grafting. This experiment used a Randomized Block Design (RAK), with five treatments, namely no media, sawdust, wet newspaper, wet cloth, and banana fronds. Each treatment was repeated five times and each unit consisted of three plants so that there were 75 experimental units. The data obtained were analyzed descriptively. The treatment of various storage media gave different responses to the success rate of grafting of Wani Ngumpen Bali plants. The best media for storing buds was wet newsprint with a success rate of 26.6% of live seedlings, supported by the number of leaves as many as 15 parameters.

Abstract

Shoot Induction of Sandalwood (Santalum album L.) With GA3 Treatment In Vitro Sandalwood (Santalum album L.) is a woody plant with high economic value whose population is decreasing due to overexploitation. Propagation of sandalwood generatively and conventionally has been carried out but the success rate is still low due to the difficulty of obtaining quality adult individuals. This study aims to find the best concentration of GA3 in inducing sandalwood shoots in vitro. This research used Completely Randomized Design with 5 levels of treatment concentration of GA3 hormone, E0: WPM without GA3 (control), E1: WPM + 1 ppm GA3, E2: WPM + 2 ppm GA3, E3: WPM + 3 ppm GA3, E4: WPM + 4 ppm GA3. The results showed that the addition of GA3 concentration succeeded in inducing sandalwood shoots. The best 1 ppm GA3 for the variable when the fastest shoots were formed, which was 2.6 (DAT), and the variable number of shoots was (10). The best GA3 concentration of 2 ppm was on the number of explants that grew shoots (2.4), the percentage of explants sprouted (0.2%) and shoot length (1cm). GA3 1 ppm and 2 ppm succeeded in growing leaves.

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.
