Diversity Arbuscular Mychorrizal Fungi from Desmodium spp. PT. Cibaliung Sumberdaya, Banten KEANEKARAGAMAN FUNGI MIKORIZA ARBUSKULA (FMA) PADA RHIZOSFER Desmodium spp. ASAL PT. CIBALIUNG SUMBERDAYA, BANTEN

Abstract

Ecosystem damage as a result of mining activity is very harmful to the environment. One of the strategy repairing the condition of post-mining land is to use legume cover crops, one type of legume cover crops is Desmodium spp., that has ability to form a symbiosis with AMF and rhizobium. The aim of this study was to determine the diversity of AMF from the four types of rhizosphere Desmodium spp. from PT. Cibaliung Sumber Daya, Banten with different types of host plants. The sampling technique of soil and roots were done by non propotional method. Soil samples were trapped with some types of host plants. Spores were isolated by wet-seaving and decanting technique, then the density of spores was measured and identified. The results showed an increasing number of spore and diversity of AMF. The number of spore before trapped was 10-89 spores per 20 g soil then increased to 16-114 spores per 20 g soil. While the AMF diversity before trapped found only 9 type of spores, consists of 8 type Glomus and 1 type Acaulospora. After trapped increased to 26 spores type AMF consists of 23 type of Glomus and 3 type of Acaulospoara. The root colonization was in range of 22.2 - 95.5%.Key word: Desmodium spp. , Cibaliung, Cover crops.

Effectiveness of inoculation types and dosages of arbuscular mycorrhizal fungi (AMF) on the growth of perintis chili variety (Capsisum annum L.) on entisol soil

“…The association between AMF and root plans can be identified by the presence or absence of structures produced by the AMF, including hyphae, mycelia, vesicles, arbuscles, and spores. The form of mycorrhizal infection seen in the roots of chili plants in this study was based on the image inspired by the study Muryati et al, [6] namely in the form of small dark round spots called vesicles. Vesicles are bulging structures formed by swelling of the main hyphae which serves as the storage of organs.…”

Arbuscular mycorrhizal colonization of pioneer mangrove species in Mahakam Delta, East Kalimantan

“…The Root samples were washed with tap water until they were clean of dirt and adhering soil. Roots staining was conducted using the method described by [17] with modification. Roots were stained with 0,05% trypan blue for analysis colonization percentage of AMF.…”

Aplikasi Fungi Mikoriza Arbuskula (FMA) pada pembibitan untuk menekan kejadian penyakit busuk pangkal batang kelapa sawit

“…Semakin tinggi jumlah spora FMA maka tingkat koloni mikoriza pada akar tanaman yang ada di dalam tanah akan semakin banyak pula. Selanjutnya menurut Muryati et al (2016) jenis tanaman inang berpengaruh terhadap persentase kolonisasi FMA, hal ini karena kemampuan infeksi dan efektivitas FMA yang berbeda pada setiap inang. Inang yang disukai oleh FMA akan memberikan tanggapan simbiotik dan kolonisasi yang maksimal.…”
