Influence of AM fungi inoculation on Capsicum annuum L. plant grown in microwave-sterilized media

Abstract

The presence of arbuscular mycorrhizal in soil may affect growth and yield of chili (Capsicum annuum L.). This experiment was done to know the effect of arbuscular mycorrhizal inoculation on growth of chilli. Microwave soil sterilization was used to reduce the number of microbes in the media, enabling to observe the interaction between chili peppers and arbuscular mycorrhizal fungi. A single culture products (A) and mixed culture products (B) were used as arbuscular mycorrhizal spores. In contrast to product A, the spore counted calculation reported that product B had the most spores, with 51 spores / 50 g soil. The treatment of arbuscular mycorrhizal fungi and microwave sterilization against the height of chili plant had no significant effect, according to a two-factor ANOVA (α: 0.05) analysis of agronomic characteristics. Inoculation of mycorrhizae had a significant effect on chili plant height. Arbuscular mycorrhizal fungi inoculation and microwave sterilization had significant effect on the root length of chili plants. Arbuscular mycorrhizal fungi in single and mixed cultures could colonize roots by forming internal hyphae, vesicles, and spores. The best way to support the growth of chili plants is to use planting media that has not been sterilized and contains mycorrhizal fungi.
