arbuscular mycorrhizal fungi in terms of symbiosis-parasitism continuum. | arbuscular mycorrhizal fungi are forming the most wide-spread mycorrhizal relationships on earth. mycorrhiza contributes to phosphorous acquisition, water absorption and resistance to diseases. the fungus promotes the absorption of nutrients and water from soil, meanwhile the host plant offers photosynthetic assimilates in exchange, like carbohydrates, as energy source. the plant benefits from the contribution of symbiotic partner only when nutrients are in low concentrations in soil and the roo ... | 2011 | 22702184 |
effects of tagetes patula on active and inactive stages of root-knot nematodes. | although marigold (tagetes patula) is known to produce allelopathic compounds toxic to plant-parasitic nematodes, suppression of meloidogyne incognita can be inconsistent. two greenhouse experiments were conducted to test whether marigold is more effective in suppressing meloidogyne spp. when it is active rather than dormant. soils infested with meloidogyne spp. were collected and conditioned in the greenhouse either by 1) keeping the soil dry (dry), 2) irrigating with water (irr), or 3) drenchi ... | 2012 | 23482862 |
