Abstract

Maize crops experiencing water stress can experience cell damage, loss of turgor, closed stomata, plant leaf roll then wilt.  Germination and vegetative growth are thought to be a very sensitive phases in relation to the availability of water, because it can influence subsequent growth processes. This study aimed to determine the potential tolerance of Southeast Sulawesi’s maize genotypes to drought stress at different vegetative growth phases. This study was based on completely randomized design (CRD) with factorial pattern consisting of two factors: the first factor composed of 9 local maize genotypes of Southeast Sulawesi and 1 national variety (cv. Arjuna), while the second factor was drought stress at different vegetative growth phases, consisting of four levels ie:  C0 = plants irrigated with 100 % water availability during the growth phase, C1 = Stress for 5 days , at 21-26 days old (vegetative phase), C2 = Stress for 5 days starting at panicle emergence (early flowering stage), and C3 = Stress for 5 days starting 2 weeks after silking.  Research results showed that Genotype (G) treatment significantly influenced all observed growth variables (at age 21 and 42 days after planting, DAP), except for the variable of number of leaf, age 21 DAP. However, water stress treatment (C) only significantly affected plant height variable, at the age of 42 DAP.   In general, G6 and G7 genotypes tended to have a higher crop and trunk diameter than the other genotypes.  Contrary, G3 genotype tended to have shorter crop and smaller stem diameter than the other genotypes.  There are indications that the drought stress treatment (C) significantly inhibited the growth of maize crops. Keywords: drought strees, maize genotypes, tolerance, and vegetative phases

Abstract

Yam (Dioscorea hispida Dennst) is a tuber crop that belonges to food sources and has not been widely recognized by the public. Aside from being a food ingredient, it can also be used as a natural pesticide. Until now, efforts to use the potential of yam have not been handled well. This research was conducted at the In vitro Laboratory of the Faculty of agriculture, Haluoleo University, from May to July 2014. The purpose of the study was to obtain the proper concentration of BAP to induce yam plant shoots in vitro. The research design used was a completely randomized design with 5 replications. One segment of the stem explants were grown on MS basic medium with different concentrations of BAP (0.5-4 ppm), with 5 replications and each replication consisted of 1 bottle containing 2 explants. Data were analyzed using Duncan's Multiple Range Test (DMRT). The research results showed that the addition of various concentrations of BAP affected the span of the emergence of the first shoots but did not affect the percentage of explants alive and growing shoots. BAP concentration of 2 mg / L was the optimal concentration to induce shoots of yam (Dioscorea hispida) with a span began to shoot appearance at week 4 after planting.

Abstract

Bacterial leaf blight caused by Xanthomonas oryzae pv. oryzae (Xoo) is an important rice disease, and has caused significant economic losses.  This research aimed to determine the pathotype grouping and the distribution of Xoo isolates of South and Southeast  Sulawesi. In order to obtain the information, 61 Xoo isolates of South Sulawesi and 29 isolates of Southeast Sulawesi were evaluated for their pathotype grouping against 5 diffential varieties. Research results showed that in South Sulawesi there were 2 pathotype groups, namely pathotype IV (32.79%) and pathotype VIII(67.21%).  Pathotype VIII was widely distributed over the Western and Central areas of South Sulawesi, whereas pathotype IV was widely distributed over the Southern area.  In Southeast Sulawesi, it was found 5 pathotypes, namely pathotypes IV (27.58%), VI (10.34%), VIII (13.79%), IX (20.68%), and X (27.58%), with a limited and scattered distribution pattern on several areas. These results indicate that  Xoo pathotype groups in South Sulawesi and Southeast Sulawesi are varied and tend to sift to more virulent pathotypes. Keywords: bacterial leaf blight, pathotype group, Xanthomonas oryzae pv. oryzae

Abstract

ABSTRAK Antosianin adalah senyawa fenolik yang bertindak sebagai antioksidan, dibutuhkan untuk tanaman itu sendiri dan nutrisi penting bagi kesehatan manusia. Pigmen antosianin menyebabkan warna merah atau biru, dan bahkan berwarna hitam ketika antosianin kandungan tinggi. Warna biru merah atau gelap terjadi tidak hanya pada pericarp dan tegmen, tetapi juga pada seluruh bagian padi. Penelitian ini bertujuan untuk menentukan kandungan antosianin pada padi gogo beras merah lokal Sulawesi Tenggara. Semua genotipe padi gogo yang digunakan dalam penelitian ini dikumpulkan dari beberapa daerah sentra penanaman padi di Sulawesi Tenggara. Analisis kandungan antosianin beras dihitung berdasarkan metode Shi et al., (1992). Analisis dilakukan di Laboratorium Analisis Pangan Fakultas Teknologi Pertanian, Universitas Udayana, Bali. Hasil analisis menunjukkan bahwa sembilan genotipe ("Paebiu Tamalaki, Paebiu Kolopua, Pae Tanta Mohalo, Paebiu Tamalaki Mataiwoi, Paebiu Sitoro, Paebiu Tamalaki Pewutaa, Paebiu Kolopua Kosebu, Ranggo Hitam, dan Hitam Lapodidi") memiliki kandungan antosianin tinggi, satu genotipe ("Ereke-1") memiliki kandungan antosianin sedang dan dua belas genotipe memiliki kandungan antosianin rendah. ABSTRACT Anthocyanin is a phenolic compound acting as an antioxidant that is necessary for plant itself and is important for human’s health. Anthocyanin pigment causes a red or blue colour, and even black when it is in a high content. Red or dark blue colour occurs not only on pericarp and tegmen, but also on all parts of paddy rice. This research was aimed to determine the variability of anthocyanin content on red up-land rice of Southeast Sulawesi. All up-land rice genotypes used in this research were collected from several up-land rice growing areas in Southeast Sulawesi. The rice kernels were analysed for their anthocyanin content based on the method of Shi et al., (1992). The analysis was conducted in the Food Analysis Laboratory of Agricultural Technology Faculty, University of Udayana, Bali. Analysis results showed that red rice of nine genotypes (“Paebiu Tamalaki, Paebiu Kolopua, Pae Tanta Mohalo, Paebiu Tamalaki Mataiwoi, Paebiu Sitoro, Paebiu Tamalaki Pewutaa, Paebiu Kolopua Kosebu, Ranggo Hitam, and Hitam Lapodidi”) had high anthocyanin content, one genotype (“Ereke-1”) had medium anthocyanin content and twelve genotypes had low anthocyanin content.

Abstract

Viability and Inhibition of Endophytic Bacteria Pseudomonas fluorescens 4RS1 Against Phytophthora palmivora in Flour Formula Pseudomonas fluorescens 4RS1 is an endophytic bacterium that has good inhibition against Phytophthora palmivora, and it has the potential to be developed as a biological agent for black pod rot disease in cocoa. It is necessary to have a formulation that can maintain viability and inhibition and facilitate its use and application, to apply this bacterial agent at the farm level. This study aimed to determine the ability of talc and tapioca flour as the ingredients of formulations that have strong solubility and maintain the viability and inhibition of P. fluorescens 4RS1. The results showed that the use of tapioca flour as the basis for the formulation of P. fluorescens 4RS1 was better than talc because it had high solubility and low precipitation. The addition of nutrients in the form of brown sugar, peptone, and CMC in the tapioca flour formulation was able to maintain the viability and inhibition of P. fluorescens 4RS1 for 12 weeks of storage.

Abstract

The  research was  conducted to  test  the  potency  of  several local  maize genotypes (landraces) of Southeast Sulawesi and to find the genotypes that were tolerant to less water conditions. The research was performed in  a  plastic house at  the  experimental farm of Agriculture Faculty, University of Halu Oleo.  The research was arranged in a Randomized Complete Design (RCD) with 2 treatment factors. The first factor was water availability level (A), consisted of 3 (three) levels (A0, A1 dan A2), and the second factor was maize genotype, consisted of 9 local maize and 1 national variety (Arjuna).  Research results showed that the less water conditions (A1 and A2) had negative effects on maize vegetative variables (plant height, plant diameter, leaf number and length of leaf tip).  On the other hand, the genotype treatment had significant effect on plant height, plant diameter, and length of leaf tip. Genotipe G7 dan G6 had the highest plant height, while G1 had the biggest plant diameter. Keywords: less water condition, local maize genotype, vegetative stage
