Abstract

Arbuscular mycorrhiza (AM) characteristics of citronella grass in the field have not been reported. This research aimed to study the AM characteristics of citronella grass grown in unshaded and shaded fields. The roots of citronella grass were collected from citronella grass plantations in Cianjur, West Java. The root samples were analyzed for AM structures, namely entry points, intercellular hyphae, arbuscules, and vesicles. The results showed that the citronella grass form AM colonization. The quality of root colonization differed between the two cultivation systems. The unshaded citronella grass had higher root colonization compared to shaded citronella grass. In the unshaded citronella grass, the number of arbuscules was 7 per cm of root length, whereas in the shaded citronella grass was 4 per cm of root length. The types of arbuscules observed were arum and intermediate. There were no differences in the number of entry points in the two cultivated systems, which was 3,5 entry points per cm of root length. The numbers of vesicles and internal hyphae in unshaded citronella grass were lower than that of in the shaded citronella grass. In the unshaded citronella grass, the number of vesicles and intracellular hyphae were 1,5 and 8,5 per cm root length, whereas in the shaded citronella grass were 3,5 and 11 per cm root length, respectively. Shading plants grown in the field were bamboo, banana, coffee, tea, and sugar palm. All the shading plants formed AM symbiosis with a colonization value of 7 to 30%. This research indicates that arbuscular mycorrhiza is an important component in the citronella grass cultivation in unshaded and shaded fields. Keywords: Arbuscule, entry point, intercellular hyphae, root colonization, vesicle

Abstract

Viability and vigor are components of seed quality assessment which are influenced by internal and external factors of the seed, i.e., salinity and temperature. Salinity is related to the interaction between osmotic pressure and seed germination. This study used 3 types of seeds, they are peanuts (Arachis hypogaea L.), mung bean (Vigna radiata (L.) R. Wilczek), and corn (Zea mays L.). The purposes of this study were to determine seed viability by using Triphenyl tetrazolium chloride (TTC), to analyze the effects of different osmotic pressures and temperatures on seed viability and vigor. Peanut seed viability test was conducted by using 1% TTC solution. Testing the effect of osmotic pressure on seed viability and vigor was conducted by using various concentrations of NaCl (0.01 M; 0.05 M; 0.5 M; 0.1 M; 1 M). The germination test of the three seeds was conducted by using temperatures of 30°C and 35°C, each with three replications. The test parameters measured included germination, germination rate, germination speed index, vigor index, simultaneous growth, and the speed of seed growth. The results showed that TTC solution was effectively used to determine seed viability. Mung bean had the highest germination rate, LP, IKP, IV, simultaneous growth, and speed of seed growth compared to the other tested seeds in all salinity and temperature treatments. The 30 ⁰C temperature treatment resulted in the best viability and seed vigor for the three tested plants. Treatments of temperature and salinity affect the quality of the three plant seeds which can then be used to determine the quality of peanut, mung bean, and corn seeds. Keywords: germination, salinity, triphenyl tetrazolium chloride, viability, vigour

Abstract

The study aims to isolate and test the effectiveness of mutualistic root symbiont fungi isolates from the roots of rubber plants grown in marginal acidic soil plantations in increasing the growth of food crops and forestry plants. The fungal were isolated by root surface sterilization methods. We obtained 19 fungal isolates consisting of 8 genera, namely Alternaria, Aspergillus, Cladosporium, Curvularia, Fusarium, Penicillium Paecilomyces, Trichoderma, and mycelia sterilia. All isolates were subjected to a pathogenicity test on the Centrosema pubescens plant. Five out of the 19 fungal isolates increased plant growth and showed no disease symptoms, and the Aspergillus section Nigri FKK 3 isolate showed the best response. The isolate was further analyzed to assess the growth response of food crops (rice and corn) and forestry plants (Acacia auriculiformis and Paraserianthes falcataria). The treatments consisted of 3 phosphate (P) concentrations, namely 20%, 50%, and 100% of the recommended field applications. The combination of mutualistic fungal inoculation of Aspergillus section Nigri FKK 3 and 50% P concentration exhibited the highest biomass growth response compared to other treatments. This finding can provide basic information for developing fungal-based fertilizers to increase the productivity of food crops and forestry plants on sub-optimal land. Keywords: food crops, phosphate fertilizer, forestry trees, plant growth improvement, root mutualistic fungi

Abstract

Environmental conditions and fish stocking density in tilapia cultivation (Oreochromis niloticus) are important factors in determining the success of the cultivation process and supporting optimal fish growth. This study used four treatments, namely A, B, C, and D, for 3, 5, 7, and 9 fish, respectively. The purpose of this study was to determine the effect of raccoon tail plants (Ceratophyllum demersum) and genjer plants (Limnocharis flava) on tilapia mortality, determine the ratio of feed conversion and the effect on ammonia concentrations, determine the effect of ammonia concentrations on the productivity of genjer plants, determine the warning system modeling on ammonia concentrations, as well as calculate mass and energy balance in the cultivation system of tilapia and genjer. The result is that the planting of raccoon tails and genjer in the system significantly affects tilapia mortality. The average value of feed conversion ratio from treatments A, B, C, and D were 1.75; 1.36; 3.51; and 2.87, respectively. The effect is significant and directly proportional to ammonia concentration and genjer productivity. The ammonia warning system modeling is in the form of linear equations, namely y = 0.2085x - 0.0193 with R2 = 0.9692. This system's balance of mass and energy can be divided into three subsystems, namely, fish acclimatization, fish cultivation, and genjer cultivation. Keywords: ammonia, genjer, modelling, tilapia

Abstract

The number and type of microorganisms in the soil indicate soil fertility. The use of fertilizers can affect the growth of microorganisms in the soil. Quantitative tests are conducted to evaluate how fertilizers affect the presence of bacteria, fungi, and algae. The number of bacteria and fungi is calculated using the standard plate count method, while the number of algae is calculated using the most probable number method. The highest number of bacteria found in urea-phosphate-potassium (UPK) applications of zeolite polymers is 50%, which is 3.4 × 106 CFU/mL; the most fungi are found in 25% of applications, which is 2.5 × 104 CFU/mL. In contrast, the highest algae population was in control soils, 2.7 × 104 CFU/mL. However, for treatment, an enormous amount is found in the administration of 50% zeolite polymer UPK as much as 1.4 × 103 CFU/mL, so it can be concluded that the administration of UPK zeolite polymer affects the number of microorganisms on the cornfield. Keywords: soil microorganism, polyacrylate, UPK, zeolite

Abstract

Ornamental plants give beauty to the surrounding environment. Fresh air is created around the plant. It is concerned with transpiration which relates to the distribution and extent of stomata. The study measured the distribution and extent of stomata in monocot plants used as houseplants. The experimental design used a complete randomized design (RAL) factorial with five replications. The main factors were six types of monocot plants and three parts of plants (top, middle, and bottom). The interaction between plant types and parts was a combination factor. The distribution and area of the stomata were measured using replica methods and micrometers. The data was analyzed using the factorial RAL model statistical analysis system and followed up with the smallest real different test for significant treatment. The distribution of stomata was correlated with the stomata area to observe the relationship between the two. Plant types, plant parts, and combinations of both have a noticeable effect on the stomata distribution and area. The Paris lilies (Chlorophytum comosum (Thumb) Jacq.) have the highest stomata distribution (20.53%) compared to others, with a stomata area of 291.89 μm2. Meanwhile, the top part of the plant has the highest distribution and differs from the middle and bottom. The highest stomata distribution is at the top of the plant (15.02%) and lowest at the bottom (11.96%), while the smallest stomata area is at the top of the plant (687.62 μm2) and the widest is at the bottom (813.88 μm2). The stomata distribution correlates inversely with the stomata area of both plant types, plant parts, and a combination of both. Keywords: ornamental plants, monocotyledon, stomatal area, stomatal distribution

Abstract

Horticultural plants are branches of agriculture that are associated with crop cultivation such as vegetables, fruit, various ornamental plants, and medicinal plants that require compounds to accelerate the formation of roots which can be done by using growth regulators. One of the growth regulators needed for plants is auxin or Indole Acetic Acid (IAA). The presence of bacteria that act as producers of IAA can be used to stimulate the growth of horticultural plants. Therefore, the exploration of bacteria that have the potential to produce auxin in the future can provide an important and significant role in increasing agricultural production. This study aims to isolate, select, measure the value of IAA, and characterize IAA-producing bacteria. Isolation of auxin-producing bacteria using general media of growth bacteria, i.e., Nutrient Agar (NA) and Nutrient Broth (NB). The location for sampling of rhizosphere soil was Prafi SP 1 Plantation, Manokwari, Indonesia. The results showed that as many as 9 bacterial isolates were obtained from the rhizosphere of horticultural plants. After selection of auxin-producing bacteria, 2 bacteria isolates (IBPA 3 and IBPA 5) were obtained which were able to produce IAA. IAA concentration value in IBPA 3 isolate is 42.178 ppm and in IBPA 5 isolate is 27.65 ppm. The characteristics of IBPA 3 isolate refer to the genus Bacillus and IBPA 5 isolate refer to the genus Pseudomonas. Keywords: agriculture, bacteria rhizosphere, indole acetic acid
