Abstract

The purpose of this research is to know the effect of moisture content of field capacity on the growth of several mutant genotypes of 3rd generation (M3) Kipas Merah soybean varieties. The research was conducted at Screen House and Soil Chemistry Laboratory  Faculty of Agriculture Syiah Kuala Universtity from May to Jun 2015. The experimental Randomized Block Design (CRBD) factorial was used, consisting of two factors and three replications. The first factor was based on the field capacity level, consisting of 100%, 80%, 60%, and 40%, and the second factor consisted of 14 mutants of 3rd generation Kipas Merah and the original Kipas Merah variety as control. The results showed that the interaction between field capacity and soybean genotype significantly affected the growth of soybean crops. In a 40% field capacity treatment of almost all the parameters tested the genotype showed no significant difference, howeverKM300-38 showed the highest plant among the genotypes tested. In a 60% of field capacity, genotype KM200-18 and KM200-37 showed better growth on all parameters tested, although not significantly different from genotype KM200-9, KM200-41, and KM300-9. Genotypes of mutant soybean that can survive and provide good growth in water shortage are KM200-18, KM200-37, KM200-9, KM300-9, and KM200-41.Selection of drought-tolerant genotypes can be performed under 40% of the field capacity.

Abstract

In an effort to increase the productivity of cocoa in Aceh, the government has carried out a cocoa plantation revitalization program for plants aged 25-30 years. The revitalization effort was constrained by the unavailability of quality seedlings. Alternatively, cocoa seedlings can be made available through vegetative propagations or through tissue culture techniques. Based on those facts, we have studied the inducing of callus and somatic embryos of cacao clones that were adaptive and highly productive in Aceh. The experiment was arranged in a completely randomized design, consisted of two factors. The first factor was the cacao genotype, having red and green fruits skin. The second factor consisted of six combinations of growth regulators 2,4-D and kinetin. The results showed that genotype of explants origin from cocoa red flowers responded very well in the formation of callus and somatic embryo formation. There was a significant interaction between genotype and growth regulator combinations on the explants in the number of somatic embryos formed. The best combination of concentrations growth regulator in response to somatic embryo in SCG (Secondary Callus Growth) medium was 3 mgL-1 2,4 D and 1 mgL-1 kinetin for explants from cocoa red flowers, and 1 mgL-1 2,4 D and 0 mgL-1 kinetin for explants origin from cacao green flowers.

Abstract

In order to fulfill the cocoa revitalization program, relatively large quantities of seedling are needed. Tissue culture is one of the alternative techniques for vegetative propagation that produce the large numbers of seedlings and uniform in a relatively short time, and also does not depend on the season. A preliminary study to induce callus and embryo somatic cocoa clones adaptive in Aceh has been carried out using immature flower parts of cocoa. The result showed that picloram was able to produce somatic embryos of staminode of various explants. Callus growth began to appear after two weeks on staminode, and then were subcultured into the same medium to produce secondary somatic embryos.

Abstract

Screening genotypes of Aceh cacao to obtain resistant genotypes to Black Pod Disease (Phytopthora palmivora) is a key step. This study was conducted on basis of screening natural infection in the field and artificial infection in laboratory. The research was conducted in the field (Saree Aceh and East Aceh) and in the Plant Pathology Laboratory, Agriculture Faculty, Syiah Kuala University. The study started from March to November 2013. Results from the field and laboratory, based on artificial inoculation, showed that three genotypes originated from Saree Aceh i.e. SR 26, SR 40 and SR7 were resistant, indicated by the characters of long incubation period (more than five days), a small diameter of spot, slow growth of the spot, and low percentage of symptoms. The three genotypes had both a good wounded post-penetration and unwounded pre-penetration resistance. Conversely, cacao genotypes originated from East Aceh did not show a significant difference of post-penetration resistance.
