Abstract

This study aimed to determine media compositions supplied with BAP and IBA suitable for the growth of black grape shoots. This research was conducted at the Laboratory of Plant Biotechnology, Faculty of Agriculture, University of Tadulako, during April to September 2016. The study used a factorial completely randomized design. Two factors were tested, the concentrations of BAP i.e. 1.50 ppm, 2.00 ppm and 2.50 ppm; and the concentration of IBA i.e. 0.00 ppm, 0.25 ppm and 0.50 ppm. There were nine treatment combinations and each combination treatment was replicated three times to obtain 27 experimental units. Each experimental unit using an explant. Data were analyzed using analysis of variance and followed by Honestly Significant Difference test at level of 5% if the treatment effects were significant. The results showed that the composition of the culture media supplied with 2.00 ppm BAP without IBA is able to stimulate the formation of black grape leaves at the earliest, at an average of 18.67 days per explant, while the media added with 2.00 ppm 0.25 ppm BAP together with IBA can lead to longest shoot growth, at an average of 2.13 cm per bud. The culture media applied with 2.50 ppm BAP can trigger earliest shoot growth and highest number of leaf formation which were 11.11 days after culture and 2.44 leaves per explant. Earliest formation of black grape shoots of 11.89 days after culture is stimulated by the addition of 0.25 ppm IBA.

Abstract

Several studies have revealed a wide range of beneficial effects of seaweed products applications on plants growth and development. Seaweeds may cause different effect in plant responses because there are a range possible factors acting in concert. These factors may include to the amount of plant growth regulator (PGR) and nutrients present in the products. PGR activity in two seaweed products (Maxicrop® and Seasol®) was investigated using Radish (Raphanus sativus). Treatments included a control, standard concentrations of the seaweed Products (SS1 and MC1), 2 and 4 times the recommended rates (SS2, SS4, MC2 and MC4) ashed seaweed products (SS-ash and MC-ash), and equivalent amounts of N, P and K to that found in seaweed products (SS-NPK and MC-NPK). The results obtained show that both Maxicrop® and Seasol® can significantly increase crop performance. Maxicrop® increased chlorophyll content and root and shoot growth, while Seasol® only increased the chlorophyll content

Abstract

Cacao is one of important plantation crops grouped in the Sterculiaceae family.  Sulawesi is the main area of cacao production and has a number of superior clones, such as Sulawesi 1 and Sulawesi 2.  Based on data in 2012/2014 cacao production to consumption reached 174,000 tons, while in 2013/2014 was projected a deficit of 115,000 tonnes. Nonetheless, cacao agribusiness in Indonesia is still facing complex problems, among others gardener productivity is still low due to borer attacks cacao, the quality of products and the number is still low and still not optimal development of cacao products and providing superior amount of cacao seedlings. The primary problem of cacao production recently is low productivity.  The main cause of low cacao productivity in Central Sulawesi is the use of inferior clones.  To enhance cacao productivity, it is crucial to use cacao clones having high genetic potential via tissue culture or micropropagation techniques.  The aim of this experiment was to assess the effect of different concentrations of 2,4-D and coconut water on the growth of cacao callus via in vitro culture.  This experiment used Completely Randomozed Block Design in factorial patteren with treatments tested namely 2,4-D and coconut water concentrations.  The concentrations of 2,4-D tested including 1 ppm, 2 ppm and 3 ppm, whilst coconut water concentrations tested consisting of 10%, 15% and 20%, and therefore there were 3 x 3 = 9 treatment combinations.  Each treatment utilized 4 replications; and each unit combination used 5 explants (staminodia).  Results of this experiment indicated that the addition of 3 ppm 2,4-D and 10% coconut water had a highly significant effect on the callus color 4 weeks after culture.  The addition of 3 ppm 2,4-D in culture media showed a significant effect on callus color 4 weeks after culture, but had an insignificant effect on the callus formation, callus color 8 weeks after culture an callus texture.  Supplementation of 20% coconut water had a significant effect on callus texture 8 weeks after culture, whilst the addition of 10% coconut water showed a significant effect on callus color 4 weeks after culture.
