Effects of vesicular-arbuscular mycorrhiza on Tagetes erecta and Zinnia elegans

Contribución de fósforo al mejoramiento de calidad en Lilium y la relación con Glomus fasciculatum y Bacillus subtilis

“…These results are explained by the close correlations were observed between the variables identified by the root dry weight and dry weight ratio of root/shoot vegetative. These correlations also suggest further colonization by G fasciculatum in the presence of B. subtilis, as well as an improvement in the rate of photosynthesis, which is consistent with the observations of Aboul-Nasr (1996).…”

“…Aboul-Nasr (1996) states that it is essential to consider the changes that AMF have on photosynthetic activity. In this paper the inoculated plants photosynthetic rate reached 17.38% higher than in uninoculated plants.…”

“…Estos resultados se explican por las estrechas correlaciones que se observaron entre las variables señaladas con el peso seco de la raíz y la relación peso seco de raíz/parte aérea vegetativa. Estas correlaciones también sugieren una mayor colonización por G, fasciculatum en presencia de B. subtilis, así como una mejora en la tasa fotosintética, lo cual concuerda con lo indicado por Aboul-Nasr (1996). the flower expressed by (PE) and (DF), greater dry weight of this organ.…”

Application of arbuscular mycorrhizal fungi on the production of cut flower roses under commercial-like conditions

“…Disagreeing with the general idea of enhanced nutrition of mycorrhizal hosts (Estaún et al, 2002), mineral analysis of rose plants did not indicate a nutritional effect of mycorrhizal inoculation in leaves, probably due to the low root colonization percentages reached. Similarly, Aboul-Nasr (1996) found that the effect of mycorrhizal symbiosis in Tagetes and Zinnia was independent of changes in nutrient contents of plants, despite the average percentage of mycorrhizal root colonization was 50%. The strongest effect of AMF was found in flower yield.…”

“…Fresh samples from the middle root system were cleared and stained (Phillips & Hayman, 1970) and the flower production, arbuscular mycorrhizal fungi (AMF) can reduce the days to flower bud emergence (AboulNasr, 1996;Scagel, 2003Scagel, , 2004aScagel & Schreiner, 2006), increase number of flowers per plant (Aboul-Nasr, 1996;Scagel, 2003Scagel, , 2004aPerner et al, 2007;Meir et al, 2010) and/or enhance flower longevity (Besmer & Koide, 1999;Scagel, 2004b). Application of AMF in rose production system could play a key role in a sustainable management of flower yield that includes reduction of chemicals and water use.…”
