Diversity and efficiency of arbuscular mycorrhizal fungi in soils from organic chili (Capsicum frutescens) farms

The peppers business is an important segment of the Brazilian agricultural market, with strong expression in the food, pharmaceutical and cosmetic industries. The objective of this work was to determine the mycorrhizal colonization rate, spore density and mycorrhizal fungi genotypes associated with the rhizosphere of ten lines of chilli peppers (Capsicum frutescens). The experimental design was completely randomized, with 10 treatments and 4 replicates, with the ten strains of Capsicum frutescens: IFET-1121; IFET-1109; IFET-1129; IFET-1119; IFET-1117; IFET-1137; IFET-1131; IFET-1127; IFET-1125 and IFET-1111. The spores of arbuscular mycorrhizal fungi (AMF) will be extracted from the soil using 50 cm³ of each composite sample, using the wet sieving technique. The determination of the percentage of mycorrhizal colonization occurred through the technique of intersection of the quadrants. The identification of mycorrhizal fungi species was by morphological comparison based on the descriptions of the reference cultures present in the International Culture Collection of Arbuscular and Vesicular-Arbuscular Mycorrhizal Fungi. The spore number and mycorrhizal colonization data will be submitted to classical statistical analysis using the Assistat program (2016). The genus Acaulospora, Claroideoglomus, Diversispora, Scutellospora, Sclerocystis, Glomus, Funneliformis and Gigaspora associated with the rhizosphere of the Capsicum frutescens strains were identified. The genera Glomus, acaulosporand Claroideoglomuswere found in all strains analyzed. The IFET - 1127 strain presented higher spore density values when compared to the other strains studied. No significant difference was found in the values of mycorrhizal colonization rate among the investigated strains

Fusarium oxysporum Schlecht et Fr. merupakan patogen tular tanah yang dapat menyebabkan layu fusarium pada cabai rawit. Penggunaan Fungi Mikoriza Arbuskula (FMA) sebagai simbion dapat meningkatkan ketahanan tanaman terhadap infeksi jamur pathogen F.oxysporum. Penelitian ini bertujuan untuk mengetahui pengaruh FMA sebagai biokontrol pertumbuhan tanaman cabai rawit terhadap infeksi F. oxysprum serta efektivitas pemberian FMA untuk menurunkan intensitas serangan penyakit layu fusarium. Bibit cabai rawit ditumbuhkan pada media tanah steril (kontrol negatif), tanah steril dan 10 ml patogen (kontrol positif), tanah steril dan FMA 100 g, FMA 100 g dan 10 ml patogen, tanah steril dan 200 g FMA, FMA 200 g dan 10 ml patogen, tanah steril dan 300 g FMA dan 10 ml patogen. Hasil penelitian menunjukkan bahwa pemberian 200 g spora FMA menunjukkan pengaruh berbeda nyata pada tinggi tanaman, jumlah daun, berat kering akar dan berat kering tajuk tanaman cabai rawit berumur tiga bulan. Sedangkan inokulasi 300 g FMA memberikan hasil terbaik pada buah cabai dan persentase kolonisasi FMA sebesar 84, 45%. Inokulasi 300 g FMA menurunkan infeksi F. oxysporum saat 30 Hari Setelah Tanam (HST) sebesar 3.36%. Kesimpulan dari riset ini menunjukkan inokulasi FMA Glomus spp. mampu meningkatkan tinggi tanaman, jumlah daun, berat kering akar dan berat kering tajuk, kecepatan berbunga dan ketahanan tanaman terhadap infeksi jamur F. oxysporum.
