“…The soil-disturbance-induced reduction in P absorption may have heen mediated through some other facet of root morphology or physiology. Clarke & Mosse (1981) and Jensen (1982) demonstrated that visually determined percentages of VA mycorrhizal infection in barley roots did not necessarily correlate with beneficial growth eflects. Furthermore, Ali (1969) found that different hyphae ofthe same plantfungus association accumulated different amounts of^P .…”

Vesicular–arbuscular mycorrhizas and the soil‐disturbance‐induced reduction of nutrient absorption in maize

SUMMARYThis study was designed to test the hypothesis that disruption of the macrostrueture of a previously zero-tilled soil is capable of reducing vesicular-arhuscular (VA) mycorrhizal infection to a degree such that phosphorus (P) absorption is reduced. Undisturbed soil cores (within plastic cylinders) were excavated from long-term, zerotilled plots. Soil removed from these plots, which was first subjected to structurally disruptive forces and then packed into identical cylinders, formed the disturbed comparisons. Maize (Zea mays L.), wheat (Triticum aestivum L.), spinach (Spinacea oleracea 1>.) or rape (Brassica iiapiis L.) were grown in the cores and P and zinc (Zn) absorption patterns monitored.Soil disturbance significantly reduced P and Zn absorption by maize grown in soil originating from thtee sites differing in local geography and/or texture. Disturbance also reduced mycorrhizal infection in the three soils.A significant effect of disturbance upon the VA mycorrhizal infection of both maize and wheat roots (both mvcorrhizal) and also upon the P absorption by these species was observed. None was found with respect to spinach and rape comparisons (non-mycorrhizal).Injection of benomyl, a potent inhibitor of mycorrhizal fungi, into the soil surface significantly reduced the influence of soil disturbance upon P absorption. No significant difierences were found in VA mycorrhizal infection within fungicide-treated cores.We accepted our hypothesis based upon the above evidence.

SUMMARYSeveral vesicular-arhuscular mycorrhizal endophytes were inoculated separately on to onion plants in soils of low P status amended with five rates of Ca(H2PO4)2. HgO. Mycorrhizal infection was usually decreased by increasing additions of P, hut the rate of root colonization and the infection plateau varied with difTerent endophytes. Plant growth responses to mycorrhiza were large at low and medium P with Glomus mosseae and Glomus epigaeum and at medium P with Glomus macrocarpum and Gigaspora margarita. Glomus caledonium and Glomus sp. 'E3' were generally effective at low, medium and high P. Glomus clarum was ineffective at low P. The correlation between infection and growth response was higher for some endophytes than others. It was concluded that analysis of the VA symbiosis with any single endophyte cannot always be used as a basis for generalization about VA mycorrhizal fungi, and that tbe selection of field inoculants should take special account of endopbyte behaviour in soils given extra pbospbate.

“…Publications investigating the effect of AM symbiosis on this female function mostly report positive or neutral effects on flower, fruit and seed production, even though exceptions also exist (Table 2). Interestingly, the response observed seems to be dependent on the fungal species used (Jensen, 1982;Schenk and Smith, 1982;Oliveira et al, 2006; Table 1), as when the same plant was inoculated with different AM fungal species, a range of responses was observed.…”

Most plant species grow in association with arbuscular mycorrhizal fungi in their roots forming arbuscular mycorrhizal (AM) symbiosis. The positive effects of this type of symbiosis on plant's performance are well known and established. However, relatively little is known about how AM symbiosis affects plant reproduction, even though reproduction is probably the most important component of life history. This review begins with a summary of the existing data on plants with monomorphic breeding systems, as most of the research has been performed using hermaphroditic and monoecious plants. Later, the limited number of studies examining mycorrhizal effects on plants with dimorphic breeding systems is detailed. Finally, several key areas for future investigations are highlighted. These include examination of the incidence of sex-specific interactions in other plant species with dimorphic systems, the influence of AM symbiosis in seed germination and establishment in plants with different gender, or the study of the mechanisms behind the AM effects seen on plant reproduction. Evidence suggests that AM symbioses are beneficial for plants with monomorphic and dimorphic breeding systems, as AM symbioses improve both sexual and asexual reproduction. However, the effects observed strongly depend on both the plant and the AM fungus species involved. Plant interactions with AM fungi and the outcome of these interactions may further depend on the gender of the host: sex-specific patterns of root colonization and sex-specific benefits from AM symbioses have been reported in several plant species. However, the incidence and the importance of sex-specific relationships between AM fungi and plants are still largely unexplored.Additional key words: clonal growth, plant sexual dimorphism, plant-fungus interactions, sex-specific interactions, sexual reproduction. Resumen Revisión. Efecto de las micorrizas arbusculares en las características reproductivas de las plantas con dimorfismo sexualLa mayoría de plantas crecen en asociación con hongos micorrícicos arbusculares en sus raíces formando micorrizas arbusculares (MA). Los efectos positivos de este tipo de simbiosis para el desarrollo de plantas son bien reconocidos. Poco se sabe de los efectos de las MA sobre la reproducción; aunque sea probablemente el rasgo más importante de la estrategia vital de una planta. Esta revisión detalla los datos disponibles sobre los efectos de las MA en la reproducción de plantas con sistemas de reproducción monomórficos y dimórficos. Se presentan los datos existentes sobre los efectos en la reproducción en plantas con sistemas de reproducción monomórficos, dado que la mayoría de los estudios se han efectuado sobre plantas hermafroditas y monoicas; se detallan los estudios que examinan los efectos de las MA en plantas con sistemas de reproducción dimórf icos; y se proporcionan líneas de investigación futuras. Los datos sugieren que las MA son mayoritariamente beneficiosas tanto para plantas con sistemas monomórficos cómo dimórficos, ya que m...
