Distribution of VA Mycorrhizal Spores in Sandy Beach Soils under Cashew
نویسنده
چکیده
Tanah berpasir dari horizon permukaan (0-15 em) di bawah tanaman gajus telah disampel dari kawasan-kawasan pantai di Besut dan Kuantan (Malaysia) untuk spora-spora mikoriza. Pengasingan sporaspora mikoriza telah dibuat daripada kedua-dua siri Rudua dan Jambu di Besut dan juga dari siri Rudua dan Baging di Kuantan. Sampel-sampel tanah dari Kuantan mengandungi lebih banyak spora mikoriza dari tanah-tanah di Besut. Keputusan kajian ini telah menunjukkan kaitan positif di antara bilangan spora mikoriza yang diasingkan dengan peratus kandungan bahan organan yang sedia ada di dalam sampel tanah itu. Pengasingan jumlah spora yang tinggi dari kawasan Kuantan (berbanding dengan bilangan spora dari Besut) berkemungkinan mempunyai kesan ke atas pengambilan baja fosforus oleh pokok-pokok gajus. Ini selanjutnya mungkin dapat menerangkan mengapa berlakunya perbezaan hasil yang diperolehi dari kedua-dua kawasan pantai ini.

Arbuscular Mycorrhizal Incidence and Infectivity of Crops in North West Frontier Province of Pakistan
Spores density and mycorrhizal colonization were studied in twenty-five rhizosphere samples of some selected soils and plant roots from fertile and marginal soils of North West Frontier Province of Pakistan. All tested plants are considered to be mycorrhizal plants. Highest number of mycorrhizal spores was found in Potatoes, Barley, rice and chickpea (>4000 spores kgG soil) in fertile soils. Fi...

Effects of the mycorrhizal fungus Glomus intraradices on establishment of subterranean clover (Trifolium subterraneum L.) seedlings in saline conditions were studied in a glasshouse experiment. Growth and nutrient uptake were determined 10, 20 and 30 days after transplanting of mycorrhizal and nonmycorrhizal matched seedlings into soils with five different levels of salinity. Mycorrhizal plants...
متن کاملThe mycorrhizal soil infectivity and arbuscular mycorrhizal fungal spore communities in soils of different aged fallows in Senegal
This work was carried out to determine the influence of the duration of fallow and of physico-chemical components of soils on the distribution of endomycorrhizal fungal spores and the mycorrhizal soil infectivity. The mycorrhization of indigenous plants from the fallows was examined and it was concluded that, except for Cassia obtusifolia, fungal colonization was poorly developed. No correlatio...

The spatial variation of arbuscular mycorrhizal fungal spores under the canopy of Acacia raddiana was studied in a desert system. Soils samples from the base of the stem, its canopy radius, and outside its canopy at four stations in the Negev desert were collected from a 0 to 50 cm depth at sections of 10 cm each. The mean spore density was found to fluctuate between 265 100 g 1 to 105 100 g 1 ...
