Abstract

Odontoglossum ringspot virus (ORSV) is one of the viruses that are reported to infect the most orchids in Indonesia. Viral infections cause economic losses. This research was conducted to study the introduction of symptoms of infection that appear as the initial stages of disease control. The source of the virus is orchid leaves Phalaenopsis amabilis positively infected by ORSV collected from Magelang. Virus isolation was carried out by mechanical inoculation to indicator plants (Chenopodium amaranticolor and Nicotiana tabaccum). Furthermore, the results of inoculation were multiplied using various types of orchids (Dendrobium, Cymbidium, Chattleya, Phalaenopsis, Spatthoglotis, Liparis, and Pecteilis). Virus detection on orchid tissue was done trough the DAS-ELISA and observation of virus structure using TEM. The results showed that Pectelis sussanae (L.) Raf. was the only orchid plant that was immune against ORSV approached. Dendrobium sp., Cymbidium sp., Chattleya sp., Phalaenopsis sp., and Spathoglotis sp. showed a response of susceptible of ORSV severe infection symptoms, while Liparis sp. were resistant. The variation of resistance from several orchid plant against infection ORSV showed severe symptoms with the incubation periode was seen earlier. The observation of virus structure using TEM showed rigid road shape particle, 300 x 18 nm in size, which is general characteristic of Tobamovirus. This indicate an infection of ORSV is a dangerous disease and require serious control

Abstract

Fusarium oxysporum is a fungal pathogen that causes plant wilt which infects many horticultural crops, including red chili (Capsicum annum L.). The continual control of pathogenic fungus with synthetic pesticides can have a negative impact on the environment, so it is necessary to look for safe and environmentally friendly alternative pathogen control methods, one of which is by using natural pesticides. Bandotan (Ageratum conyzoides L.) is known as a weed, containing secondary metabolites with antifungal activity. This study aims to determine the effect of bandotan stem extract on the growth of Fusarium oxysporum in infected chili plants during the germination phase. The study was conducted using a Completely Randomized Design (CRD) with one treatment factor, namely the method of giving bandotan extract consisting of 5 replications. ANOVA results at α = 5% showed that 65% dry bandotan stem extract did not reduce Fusarium oxysporum growth on the red chili plants.

Abstract

Cayenne pepper (Capsicum frutescens L.) is a shrub plant of the Solanaceae family that is famous for its spicy taste and high demand in Indonesia. However, the growth of cayenne pepper plants requires optimal plant nutrients. One way to increase plant growth is through fertilization, either with organic fertilizer in the form of bean sprout extract (Vigna radiata L.) or the provision of Growth Regulators (ZPT) in the form of atonik. This study aims to determine the effect of bean sprout extract and atony on the growth of cayenne pepper, determine the most effective concentration of bean sprout extract and atony, and identify the interaction between the two. The research was conducted from February to April 2024 at the Botany Laboratory of FMIPA, University of Lampung, using a completely randomized design (CRD) with a factorial design. The first factor was the application of bean sprout extract with three concentrations (0%, 5%, and 10%), while the second factor was the application of atonic solution with two concentrations (0% and 10%). Each treatment was repeated five times, resulting in 30 experimental units. Parameters observed included plant height, root length, chlorophyll content, leaf visualization, fresh weight, dry weight, and relative water content. The data obtained were analyzed using Analysis of Variance (ANOVA) and Tukey's further test at the 5% level. The results showed that the application of 5% bean sprout extract and 0% atonik gave the best results in plant height, root length, and relative water content. The interaction between bean sprout extract and atony had an effect on the growth of cayenne pepper, but did not have a significant effect on chlorophyll content.
