Jumlah Spora dan Genus Endomikhoriza pada Tanah Monokultur dan Tumpangsari Jeruk Siam (Citrus nobilis Tan.) dengan Tanaman Sayuran di Desa Sekaan Kecamatan Kintamani
Abstrak: Endomycorrhiza is a
wide spread fungi that develop symbiotic association with numerous plant types
except for Brassicaceae and Chenopodiaceae. Endomycorrhizal fungi colonized
plants through spore or hypha propagation. The spore number of endomycorrhiza
was studied in the soil of orange orchard in the Bali’s center of orange fruit
production located in Sekaan Village, Bangli District during November 2015 –
January 2016. The orange plants were cultivated in monoculture and intercropped
with the following vegetable crops : cucumbers (Cucumis sativus L), tomatoes (Solanum
lycopersicum), mustard greens (Brassica rapa subsp. Pekinenshis), and cabbage (Brassica
oleracea var. capitata). Three replications of soil samples were taken
purposively and separately proceed for laboratory analysis. The following
parameters were measured: total spore number and genus types of endomycorrhiza,
the content of soil available-P, soil pH, and soil organic-C. The experiment result
showed that monoculture system had significant higher number of VAM spores (347
spores) compared to intercropping (178 – 224 spores). Most of VAM spore had
small size ranging on 45 – 105 µm (60,80%) followed by106 – 249 µm (33,82%) and
the least were ≥ 250 µm spores. There were two MVA genus present in the soil of
both cropping patterns which grouped to Acaulospora (3 morphotypes)and Glomus
(11 morphotypes). The highest number of VAM spores belongs to Glomus.The soil
properties that closely related to VAM spore number was soil pH ( =0.66**).
