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

This study aims to investigate the effect of combining Kinetin and IAA on the growth of kepok banana shoots in vitro. The research was conducted at the In Vitro Laboratory, Agrotechnology Unit, Faculty of Agriculture, Halu Oleo University, from January to April 2023. The study utilized a Completely Randomized Design (CRD) with six treatments: P1 = (Kinetin 1 mg L⁻¹ + IAA 2 mg L⁻¹), P2 = (Kinetin 3 mg L⁻¹ + IAA 4 mg L⁻¹), P3 = (Kinetin 5 mg L⁻¹ + IAA 6 mg L⁻¹), P4 = (Kinetin 2 mg L⁻¹ + IAA 1 mg L⁻¹), P5 = (Kinetin 4 mg L⁻¹ + IAA 3 mg L⁻¹), and P6 = (Kinetin 6 mg L⁻¹ + IAA 5 mg L⁻¹). Each treatment had five replicates, resulting in 30 experimental units, with four Kepok banana shoot explants per culture bottle. The observed variables included shoot emergence time, number of shoots, shoot length, and shoot growth percentage. Results indicated that the combination of Kinetin and IAA concentrations significantly affected the number of shoots and shoot emergence time and shoot length, but did not significantly affect the shoot growth percentage. The best treatment was P2 = (Kinetin 3 mg L⁻¹ + IAA 4 mg L⁻¹) for in vitro growth of Kepok banana shoots.

Abstract

Abstract Citrus Vein  Phloem Degeneration (CVPD) is  one  of  the  most important diseases of citrus. Worldwide and national yield losses of citrus production due to this disease infection have been very significant.   This research ultimately aimed at producing citrus stocks through in-vitro culture, and free of CVPD.  Citrus seeds were used as explant and cultured on MS and WPM in-vitro media, supplemented with malt extract. Citrus plantlets were tested for the presence of  CVPD DNA using CVPD specific primers in PCR reactions.   Research results showed that MS basal medium supplemented with malt extract was quite good for in- vitro production of citrus plantlets. Plantlets were negative for CVPD infection based on PCR tests.  CVPD-free seedlings (Citrus reticulata) have been grafted with citrus rootstock (Citrus sinensis).  Grafted citrus seedlings were also proven to be negative for CVPD infection based on similar PCR tests.  Citrus seedlings/stocks produced by in-vitro culture, and free of CVPD, are now available for further growth. Keywords: Citrus Vein Phloem Degeneration (CVPD), in-vitro culture, PCR

Abstract

This study aims to determine the genetic diversity of several local cayenne pepper cultivars from Southeast Sulawesi and to find out which local cayenne pepper cultivars from Southeast Sulawesi show the best growth and yields. This research was carried out at the Agricultural Extension Center (BPP) Pilot Land located in Langkoroni Village, Maligano District, Muna Regency. The research implementation time starts from October 2021 to February 2022. Data analysis using variety fingerprints, if it shows a real and very real influence then continued Duncan multiple range test (DMRT) with the help of statistical product and service solution (SPSS) application facility and calculate genetic diversity value. The results showed that quantitative characters with high diversity were found in the characters of flowering age, harvest age, number of fruits, fruit weight, fruit length and fruit diameter. Somewhat high is found in the character of plant height and leaf area. Slightly low was found in the character of the number of leaves and low was found in the character of the length of the fruit stalk. The qualitative characters observed were uniform because there were no differences in the observed local cayenne pepper cultivars from Southeast Sulawesi. The local cayenne pepper cultivar from Southeast Sulawesi that showed the highest growth and fruit yield was found in the cultivar from Kolaka (145.96 grams/plant), followed by North Buton-2 (125.71 grams/plant), then South Konawe (121.93 grams/plant) compared to other local cayenne pepper cultivars.

Abstract

Ginger (Zingiber officinale Rosc.) is one of the spices and medicinal plants which has many benefits and usefulness. Currently ginger production in Indonesia is still very low, du e to limited sources of genes possessed by plant breeders (narrow genetic stock), therefore it is  necessary to  obtain new  genetic diversity. The  purpose of  this  study was  to  conduct exploration activities to collect local ginger germplasm in Southeast Sulawesi to get information in the form of (a) genetic diversity of accessions, (b) determination that can be used to identify germplasm genetic diversity of ginger of Southeast Sulawesi, (c) description of the collected ginger types, for the benefit of ginger crop improvement through breeding programs. This study began with exploration activities, then planting accessions for collection and conservation which will be utilized in various ginger breeding programs. The results of exploration obtained as many as 18 accessions from Kendari, Konawe, Bombana, Muna and Buton regencies. Results of the collection of some areas of Southeast Sulawesi showed that ginger genetic diversity was quite high, seen from the morphological appearances of the rhizome.  Based on the size, shape and color of the rhizome, the ginger accessions of Southeast Sulawesi can be classified into three major groups, i.e. large white/yellow ginger, small white/yellow ginger, and red ginger. White ginger was large and more attractive than red ginger, but less spicy aroma due to its low essential oil content, and less disease resistant, but high productivity. Keywords: ginger, Zingiber officinale, genetic diversity

Abstract

This research was conducted in a factorial pattern of split plot design, with three factors.  The first factor (as main plot) was acidity (pH), with two treatment levels: pH 4.5 (P1) and pH 6.5 (P2); the second factor (as sub plot) was aluminium concentration, with four treatment levels: 0 ppm Al (A1), 50 ppm Al (A2), 100 ppm Al (A3), and 150 ppm Al (A4); and the third factor (as sub-sub plot) was variety, with eight treatment levels: SU-025 (V1), ST-028 (V2), ST-050 (V3), ST-070 (V4), ST-079 (V5), SE-081 (V6), SE-090 (V7), and SU-094 (V8). Each treatment was repeated twice, resulting in 128 experimental units. The objectives of the research were: (1) to study the effect of acidity, aluminium concentration and their interactions on the growth of several maize varieties, (2) to obtain maize varieties which were tolerant to acidity and high aluminium concentration. Research results showed that acidity influenced leaf area and size.  Aluminium influenced stem diameter, leaf area, total leaf weight, plant height, and  dry weight of  top  plant parts (stem  and  leaves).    Variety influenced   all   growth   characters,   except   leaf   size.   Interaction   between   acidity   and aluminium concentration influenced seminal root length.   Interaction between acidity, aluminium and variety influenced lateral root length, whereas interaction between acidity and variety had no influenced on all plant growth characters.  Concentration of 50 ppm Al gave a better effect compared to the concentration of 150 ppm Al.   The growth of maize variety ST-028 (V2) and SU-025 (V1) gave a better yield, compared to other varieties. Keywords: acidity, aluminium, maize, in vitro

Abstract

The soil quality of Ultisol, which is indicated by its chemical properties, arbuscular mycorrhizal fungi (AMF), and root nodules, is important for soybean growth. Cogongrass biochar enriched with N fertilizer solution using solvent from seaweed extract can change the soil quality. Using various seaweed extract solvents, this study sought to (i) test the impact of cogongrass biochar enriched with N fertilizer solution on the soil chemical quality and (ii) examine the effects of soil chemical changes on AMF, root nodules, tissue nutrient content, and soybean yield. The treatments consisted of (i) without biochar (B0), (ii) cogongrass biochar without enrichment (BN0), (iii) cogongrass biochar enriched with urea solution using solvent from extract of Kappapychus alvarezii (BNK), (iv) cogongrass biochar enriched with urea solution using solvent from extract of Sargassum sp. (BNS), and (v) cogongrass biochar enriched with urea solution using solvent extract of Ulva lactuca (BNU). In a randomized block design, each treatment was carried out three times. With or without fertilization, cogongrass biochar improves the chemical fertility of the soil. The increase in NH4+-N and nitrate-N content of the soil in enriched cogongrass biochar was greater than in unenriched. The AMF spores density and root nodules were reduced following enrichment. When biochar was added, there were more pods, pod dry weight, total seeds, and regular seeds per plant. In conclusion, the impact of increasing soil ammonium content led to decreased density of AMF spores, root infections, and root nodules. The level of available P greatly affected the components of soybean yield in Ultisol.
