“…increase flower yield between 30 and 50%. Similar results have been reported in number of ornamental plants in response to mycorrhizal inoculation (Aboul-Nasr, 1996;Gaur et al, 2000;Sohn et al, 2003;Scagel, 2003Scagel, , 2004aNowak, 2004;Meir et al, 2010) even with commercial formulations (Perner et al, 2007). The enhancement of flowering in plants inoculated with G. mosseae was independent of foliar nutrient concentration, suggesting a non-nutritional basis of the effect of mycorrhizal association, as Aboul-Nasr (1996) explained in flower production of Tagetes and Zinnia after their inoculation with G. etunicatum.…”

“…On the other hand, the vase-life of cut flowers is a commercially important trait. AMF can increase flower longevity (Scagel, 2004b), induce early flowering (Gaur et al, 2000) or raise weight, width and height of flowers (Sohn et al, 2003). Higher nutrient uptake as N, K and Mn, and increased carbohydrates concentration due to AMF symbiosis seems to be crucial (Sohn et al, 2003;Scagel, 2004b).…”

The objective of this work was to study the influence of two arbuscular mycorrhizal fungi (AMF) -Glomus mosseae (Nicol. & Gerd.) Gerd. & Trappe, and G. intraradices (Schenck & Smith)-on cut flower yield of rose (Rosa hybrida L. cv. Grand Gala) under commercial-like greenhouse conditions. Flower production was positively influenced by G. mosseae inoculation. Both inocula tested caused low levels of mycorrhizal root colonization, with higher percentages in Rosa associated with G. mosseae. Significant improvement of plant biomass, leaf nutritional status or flower quality was not detected in inoculated plants probably due to the low symbiosis establishment. However, G. mosseae reduced by one month the time needed for 80% of the plants to flower and slightly increased number of cut flowers relative to non-mycorrhizal controls on the fourth, sixth and eighth months after transplanting. It is suggested that an altered carbohydrate metabolism could contribute to this positive effect. Low colonization of rose roots supports the idea that more effort is required to ensure successful application of AMF in ornamental production systems.Additional key words: Floriculture; Glomus intraradices; Glomus mosseae; phosphorus; Rosa hybrida. Resumen Aplicación de hongos micorrícico-arbusculares en el cultivo de rosas para corte bajo condiciones comercialesEl objetivo de este trabajo fue evaluar el efecto de los hongos micorrícico-arbusculares (MA) -Glomus mosseae (Nicol. & Gerd.) Gerd. & Trappe, y G. intraradices (Schenck & Smith)-en la producción comercial de rosas para corte (Rosa hybrida L. cv. Grand Gala) en invernadero. La inoculación con G. mosseae influyó positivamente en la producción de flores. Los resultados mostraron bajos niveles de colonización micorrícica de las raíces de rosa independientemente de la especie empleada, si bien las plantas tratadas con G. mosseae presentaron mayores porcentajes de colonización. El reducido establecimiento de la simbiosis muy probablemente fue la causa de que no se observara un aumento significativo de la biomasa vegetal o una mejora del estado nutricional y calidad de las flores en las plantas inoculadas. No obstante, la aplicación de G. mosseae redujo en un mes el tiempo requerido para que el 80% de las plantas estuviesen en floración y provocó un ligero aumento de la producción de flores en comparación con las plantas no micorrizadas, en el cuarto, sexto y octavo mes tras el trasplante. El metabolismo del carbono de estas plantas pudo haber contribuido al efecto positivo sobre la producción. La baja colonización micorrícica alcanzada por las raíces de rosa sugiere ajustar las condiciones de cultivo con el fin de mejorar la aplicación de las MA en los sistemas de producción ornamental.

“…AM fungi are also reported to influence traits that may affect pollinator behaviour. Not only do mycorrhizal plants produce more flowers (Table 2) or flowers which produce more pollen (Table 1), but AM symbioses may also cause plants to flower for a longer period of time (Koide et al, 1988); increase the quality as well as the quantity of nectar (Gange and Smith, 2005) or increase flower size (Sohn et al, 2003;. Mycorrhizal symbiosis has also been shown to increase plant height (Lu and Koide, 1994;, and elevating the flowers higher above ground may influence insect visitation (Lortie and Aarssen, 1999).…”

Effects of arbuscular mycorrhizas on reproductive traits in sexually dimorphic plants: a review

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.

“…Similar effects of AMF-inoculation on the time of shoot emergence of wild hyacinth (Scagel, 2004b) and Easter lily (Lillium longiflorumm) (Mora, 1990) have been reported. AMF have been shown to preferentially alter allocation to the symbiosis over flowering (Korhonen et al, 2004) and enhance early flowering (Sohn et al, 2003); however, flower initiation and development in the species used in these studies occurs during the growing cycle in which the plant produces flowers. With calla, flower buds are pre-formed prior to planting (Funnell, 1993) and floral differential occurs under conditions suitable for vegetative development (Funnell et al, 2002); therefore we hypothesized that AMF-inoculation would have little influence on flowering of calla during the first growing cycle after inoculation.…”

One-year old tubers of two hybrid calla lily (calla) cultivars (Zantedeschia 'Pot of Gold' and 'Majestic Red') were inoculated with the arbuscular mycorrhizal fungus (AMF), Glomus intraradices, or not, and grown at three different rates of phosphorus (P) supply to asses the effects of AMF-inoculation on plant development (time of shoot emergence and flowering), flowering (number, length and rate of flowering), and tuber biomass and composition over two growing cycles (2002, 2003). Tubers and flowers of calla responded differently to AMF inoculation. Differences in mycorrhizal responsiveness between cultivars was related to differences in P requirements for flower and tuber production, and the influence of P supply on resource allocation to different reproductive strategies. Inoculation increased shoot production and promoted early flowering, particularly in 2003. Inoculated plants also produced larger tubers than non-inoculated plants, but only increased the number of flowers per plant in 2003. High P supply also increased tuber biomass, but decreased the number of flowers per plant in 2002. Plants grown at a moderate P-rate, produced the most flowers in 2003. For 'Majestic Red', benefits from AMF were primarily in terms of tuber yield and composition, and AMF effects on marketable flower production could potentially have negative impact on production strategies for growers. Inoculation of 'Pot of Gold' primarily influenced flower production and aspects of tuber quality that caused detectable enhancement of tuber yield and flowering in the second growing cycle following inoculation (2003). The results of this study show that the responses of calla to AMF are partially a function of how nutrient supply alters resource allocation to sexual and vegetative reproduction. Whether AMF-induced changes in resource allocation to flowering and tubers significantly alters commercial productivity and quality of calla depends on the crop production goals (e.g. tubers, cut flowers or potted plants).
