Symbiotic associations were established between nitrogen-fixing nonleguminous (actinorrhizal) snowbrush (Ceanothus velutinus Dougl.) seedlings and two categories of microorganisms: vesicular–arbuscular (VA) mycorrhizal fungi and a filamentous actinomycete capable of inducing nodule formation. The actinomycete is housed in nodules where fixation of atmospheric dinitrogen occurs and is made available to the host plant; the mycorrhizal fungus is both inter- and intra-cellular within the root tissue and may be found within the nodules. The two major nutrients, N and P, are made available and can be supplied to the host plant by these two symbiotic microorganisms. The root system of snowbrush seedlings was dually colonized by VA mycorrhizal fungi and a nitrogen-fixing actinomycete and the possibility of a direct interaction between the endophytes in the symbioses was investigated. Dually infected plants showed increases in total dry weight of shoots and roots, number of nodules, weight of nodular tissue, as well as higher levels of N, Ca2+, and P, and an increase in nitrogenase activity as measured by acetylene reduction.

Endemic plants of the Sonoran Desert of Baja California were sampled for mycorrhizal associations. Eight of the 10 plant species examined were colonized by vesicular–arbuscular (VA) mycorrhizal fungi. Soil sievings revealed chlamydospores of three VA mycorrhizal Glomus spp.; G. microcarpus, G. fasciculatus, and G. macrocarpus. At the time of sampling, the populations of VA fungal spores in the soil were low, with one to five chlamydospores per 100 g soil sample.

<p>ABSTRAK<br /><br />Pengembangan hijauan membutuhkan pupuk ramah lingkungan. Fungi Mikoriza Arbuskular (FMA) adalah asosiasi yang melibatkan jamur dan akar yang dianggap sebagai pupuk hayati untuk meningkatkan produktivitas tanaman dan toleran dari kondisi lingkungan. Ketersediaan FMA masih jarang, sehingga dibutuhkan produksi massal untuk dapat mendukung pengembangan hijauan. Tujuan dari penelitian ini adalah untuk menghasilkan inokulum AMF menggunakan sistem hidroponik dalam jumlah besar secara efektif. Penelitian ini dibagi menjadi 2 tahap. Rancangan Acak Kelompok Faktorial yang digunakan pada tahap pertama dengan faktor A adalah jenis sistem irigasi (Manual, Drip dan Nutrien Film Technique System (NFT)) dan B adalah larutan nutrisi (AB Mix dan Hyponex Red) dengan Pueraria javanica sebagai tanaman inang. Rancangan Acak Lengkap (RAL) dilakukan pada tahap kedua dengan menggunakan produksi inokulum FMA dari tahap pertama dengan Brachiaria decumbens var Mullato sebagai tanaman inang. Hasil penelitian menunjukkan bahwa interaksi antara sistem NFT dan AB Mix signifikan (P&lt;0,05) menghasilkan bahan kering tajuk, bahan kering akar dan spora paling tinggi. Semua tipe sistem irigasi dan nutrisi menunjukkan infeksi akar&gt;96%. FMA inokulasi di Brachiaria decumbes var Mulato signifikan(P &lt;0,05) pada bahan kering tajuk, kandungan N, kandungan P dan serapan P.</p><p><br />Kata kunci: Brachiaria decumbes, FMA, sistem Drip, sistem NFT, Pueraria javanica,</p><p><br />ABSTRACT</p><p>Forage mass production development requires environmental friendly fertilizer. Arbuscular Mycorrhizal Fungi (AMF) are mutualitic symbioses between plant and fungi that considered as natural biofertilizer with benefit to improve plant productivitity and environment stress tolerance. The availability of AMF is still low, so it takes mass production to be able to support forage development. The aim of the research was to produce AMF inoculum using hydroponic system in large quantities. This research divided into 2 stages. The factorial randomized block design was used for the first stage with A factor was type of irrigation system (Manual, Drip and Nutrient Film Technique System (NFT)) and B was the nutritional solution (AB Mix and Hyponex Red) using Pueraria javanica as host plant. Completely randomized design was conducted for the second stage by using AMF inoculum production from first stage using Brachiariadecumbens var Mullat as host plant. The best result was a combination beetwen NFT system and AB Mix significantly (P&lt;0.05) produce highest shoot dry matter, root dry matter and spore production. All type of irrigation system and nutrition showed root infection &gt;96%. AMF inoculation in Brachiariadecumbes var Mulato was significant different (P&lt;0.05) on shoot dry matter, N content, P content and P uptake.</p><p><br />Keywords: AMF, B. decumbes, Drip system, NFT system, P. javanica,</p>
