Abstract

An experiment aimed in gaining information on morphological characteristics of Jatropha curcas (L.) containing high frequency of uninucleate microspores has been done. This was important due to the successful application of experiment in haploid technique through anther or microspore culture is strongly determined by the availability of information from basic research such as appropriate morphology of the flowers. This scientific article, in our knowledge, was an early explanation of the initial steps of whole procedures in the microspore culture of Jatropha curcas (L.).  Results of the research showed that the morphological features of flower that contained high frequency of mid- and late uninucleate microspores was that the flowers must be in the range of 2 to 3 mm in length. Such flowers contained yellowish anthers.Key words: Flowers length, mid- and late-uninucleate, morphology, physic nut, microspore

Abstract

The objective of this research was to evaluate the effect of seed invigoration on improving seed viability and vigor, and to overcome problems of postharvest physiological dormancy of upland rice seed. The research was conducted from February to June 2011 at Agrotechnology Laboratory, Faculty of Agriculture, Halu Oleo University. The experiment used randomized complete design which consisted of 13 treatments, i.e control (G0), Hidration-Dehidration (G1), Matriconditioning using ground brick (G2), Matriconditioning using ground burned-rice husk (G3), Bacillus CKD061 (G4), P. fluorescens PG01 (G5), Serratia CMN175 (G6), Biomatriconditioning using ground brick + Bacillus CKD061 (G7), Biomatriconditioning using ground brick + P. fluorescens PG01 (G8), Biomatriconditioning using ground brick + Serratia CMN175 (G9), Biomatriconditioning using ground burned-rice husk + Bacillus CKD061 (G10), Biomatriconditioning using ground burned-rice husk + P. fluorescens PG01 (G11), Biomatriconditioning using ground burned-rice husk + Serratia CMN175 (G12). Each treatment was replicated three times, therefore, overall there were 36 experimental units. Data obtained were analyzed using analysis of variance and followed with Duncan’s Multiple Range Test. The research results showed that bio-invigoration treatments integrated with rhizobacteria were effective to overcome the problems of postharvest physiological dormancy when local upland rice seeds were harvested. In addition, this treatment was also able to increase viability and vigour of the seed. Among treatments tested, the use of Bacillus sp. CKD061 or P. fluorescens PG01, either independently or integrated with matriconditioning using ground brick or ground burned- rice husk was more effective in improving viability and vigour of local upland rice seed compared to other treatments.

Abstract

The objective of this research was to evaluate and assess the level of run-off  and erosion on various types of land use in the Upper Jenneberang Sub Watershed. This research was conducted in the Upper Jenneberang Sub Watershed, Saluttoa Village, Sub Tinggimoncong, Gowa regency, South Sulawesi Province. Land use type (LUT) which was used as land units of observations was determined based on land use maps of upper Jenneberang sub watershed. Based on the analysis results of map and observation in the field, it was defined four types of land use as land units of observation: 1) Natural forest, 2) Gliricidia tree-dominated agroforestry, 3) Coffee tree-dominated agroforestry, and 4) Maize monoculture. Each LUT was given the observation plot size 30 m x 10 m and plot placement was determined randomly. All LUT had slope 26%, soil type of Brown Latosol at the same altitude and climate. The composition of the observation plot was based on Randomized Block Design (RBD). Collected data on LUT included: soil physical properties, infiltration rate, run-off and erosion. The result showed that changes in land use of natural forests into agroforestry and maize monoculture types resulted in decreased amount of woody vegetation that resulted in increased run-off and erosion. Keywords : run-off, erosion, agroforestry

Abstract

The study aimed to classify soybean genotypes that are tolerant, moderate and sensitive to drought and acidity. The results are expected to give a contribution in the development of Soyban on dry land and acid soil.  Increasing of genetic diversity was carried out through mutation induction by gamma ray in soybean seeds. The experiment was conducted in green house by using the method in the form of a two-factor factorial design laid out in the draft group. The first factor was the variety (V) which consisted of three kinds, namely soybean Menyapa varieties (v1), Orba (v2), and Tanggamus (v3). The second factor was the dose of gamma-ray irradiation (D) consisted of 4 doses of 0 Gy (d0), 25 Gy (d1), 50 Gy (d2), and 75 Gy (d3) at concentrations of PEG and Al which showed that the level of diversity the biggest concentration of 30 previous trials of PEG+10 ppm Al. The volume of nutrient solution (Hoagland's) maintained in accordance with the initial volume by adding distilled water, and the solution was maintained at pH 4 using NaOH and HCl 1N. The results showed that the grouping was based on drought tolerant and acidity as follows: genotypes tolerant were varieties Menyapa 50 Gy gamma irradiation, variety of Orba 25 Gy of gamma irradiation, gamma irradiation variety Tanggamus 0 Gy, 25 Gy, 50 Gy of gamma iradiation. Moderate genotype were varieties Menyapa 75 Gy of gamma irradiation, variety Orba 50 Gy, 75 Gy of gamma irradiation, variety Tanggamus 75 Gy of gamma irradiation; genotype susceptible were variety Menyapa 0 Gy, 25 Gy of gamma irradiation; variety Orba without gamma irradiation of 0 Gy.

Abstract

The success of foot rot disease control is largely dependent on information data of pepper cultivation conditions, distribution pattern of the disease, and the magnitude of the intensity of the disease. This study aimed to determine the condition of pepper cultivation, distribution pattern of pepper foot rot disease, the development of disease symptoms, and intensity of pepper foot rot disease in Southeast Sulawesi. Data cultivation conditions, distribution of the disease, progression of symptoms, and the intensity of the disease were obtained by means of surveys in pepper plantations and interviews with pepper farmers. The results showed that the pepper plantations in Southeast Sulawesi were cultivated on flat to hilly topography, and the cultivation method was very conventional but herbicide use was very intensive. The development of wilt symptoms on pepper plants was very quick in dry weather but slow in the wet. Pepper foot rot disease has patch distribution. The highest intensity of the pepper foot rot disease was in less weedy plantations with intensive use of herbicides. The intensity of the pepper foot rot disease in Southeast Sulawesi was 61,2% with the spread in each district namely South Konawe at 53,8%, Konawe at 63,7% and Kolaka by 61,2%.
