Abstract

The purpose of this research was to examine interaction effect between the different concentration of BAP hormone (Benzylaminopurine) and Kinetin hormone on the shoot induction of Jati (Tectona grandis L.) with in vitro method. This research used a completely randomized factorial design with 4x3 factorial pattern. The first factor was the concentration of BAP (B0 = 0 ppm; B1 = 1 ppm; B2 = 2 ppm dan B3 = 3 ppm). The second factor was concentration of Kinetin (K0 = 0 ppm; K2 = 0,75 ppm; dan K3 = 1,5 ppm). The parameters observed were time of callus appearance, callus length, time of shoot emergance, number of shoots, length of shoots, time of leaf development, number of leaves, percentage of growth, and percentage of contamination. The parameters obtained were analysed descriptively because the percentage of total growth was under 50%. The result showed that the concentration 1 ppm BAP and 0,75 ppm kinetin was better for stimulating the appearance of callus, shoots, leaves, and number of shoots. Callus diameter was better at concentration of BAP 3 ppm. The callus texture that was formed was included in the compact texture. The percentage of explants life was 33,30 – 66,60%. No contamination occurred in all explant samples.

Abstract

This research aimed to assess the effect of Naphthalene Acetic Acid (NAA) and nitrogen fertilizer on the growth of sugarcane (Saccharum officinarum L.) bud chip. The research was conducted using a 4 x 4 factorial design with the basis of a completely randomized design (CDR) of 3 replications. The first factor was the concentration of NAA which consisted of 0 ppm (without NAA), 50 ppm, 100 ppm, and 150 ppm. The second factor was the dose of nitrogen fertilizer which consisted of a dose of 45 kgN/ha, 90 kgN/ha, 135 kgN/ha, and 180 kgN/ha. The growth parameters observed included plant height, number of leaves, tillers, root dry weight, and shoot dry weight. The data were analyzed by analysis of variance and continued with Duncan’s test (Duncan’s Multiple Range Test) at a 5% level. The results showed that the application of NAA could not increase the growth of sugarcane bud chips on all parameters. Application of nitrogen fertilizer at a dose of 45 kg N/ha could increase plant height growth, number of leaves, root dry weight, and shoot dry weight. Nitrogen fertilizer with a dose of 180 kg N/ha reduced the growth of sugarcane bud chips. The higher dose of nitrogen fertilizer inhibited the growth of sugarcane bud chips.

Abstract

One of phosphate (P) fertilizer i.e. SP-36 is expensive and can be obtained by rock phosphate(RP). Rock phosphate combined with Vesicular Arbuscular Mycorrhizal fungus (VAM) could increaseP availability. VAM consists of many species, so it is necessary to test the role of VAM species oncherry tomato plant. This study aims to examine the effect of VAM species and phosphate fertilizationto improve cherry tomato production. The research use a Completely Randomized Design (CRD)which consisted of two factors with three replications. The first factor is the phosphate fertilization (P0=without P fertilizer, P1= SP-36, P2= rock phosphate) and the second factor is VAM species (M0=control without mycorrhizae, M1= Glomus etunicatum, M2= Glomus fasciculatum, M3= doubleinoculation of G. etunicatum and G. fasciculatum). The results show that mycorrhizae inoculationincreases plant height, fruit number, fruit weight and accelerates flowering age compared to withoutinoculation. BP fertilization increases fruit weight. BP+CMA produces number of fruit equivalent to SP36+CMA. BP+G. etunicatum treatment significantly increases fruit weight compared to SP-36+G.etunicatum. G. etunicatum inoculation gives the highest fruit weight compared to other inoculation.
