“…These types of carry-over effects of AMF are important to consider with perennial crops where growth and development in one growing cycle depends upon plant history from the prior growing cycles and on current growing conditions. Arbuscular mycorrhizas have been shown to enhance uptake of nutrients other than P (Clark and Zeto, 2000). The ability of AMF to enhance P in tubers without influencing tuber growth for 'Pot of Gold' suggests that AMF inoculation enhanced P uptake, but other nutrients still limited tuber growth.…”

“…For example, Clemens et al (1998) found that high nitrogen (N) reduced tuber size and subsequent flowering performance in the following growing cycle, while moderate to low N, P, and potassium (K) increased flower production and reduced time to harvest. Since AMF can increase the efficiency of uptake and use of different nutrients, especially P (Clark and Zeto, 2000), the potential effects of AMF on nutrient and carbon allocation patterns of calla could influence vegetative multiplication, flowering, and ultimately impact crop productivity and product quality. Most prior studies assessing the influence of AMF on floral geophytes (Scagel, 2004a, b;2003a, b) have not addressed whether mycorrhizal response of the plants was a result of altered P nutrition.…”

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).

“…AM is significant for improving growth of various crop plants particularly in low fertility soil (Clark & Zeto, 2000;Smith & Read, 2008). Through their fungal external hyphae help plant roots to explore and absorb water and nutrients from bulk soil beyond depleted root zone resulting in increased P uptake, and other nutrients such as Ca, Cu, Mn and Zn.…”

A pot experiment was conducted under glasshouse conditions to evaluate response of some cowpea genotypes to Arbuscular Mycorrhiza. It was a 2 x 6 factorial experiment comprising factors of mycorrhizal inoculation (M) with AM fungal inoculum (M 1 ) and without AM fungal inoculum (M 0 ), and of plant genotypes (G) with G f (a cowpea inbred line), G m (a mung bean inbred line), G h1, G h2 , G h3 and G h4 (the 1 st , 2 sd , 3 rd and 4 th generation of cowpea hybrids, derived from cross-breeding G f x G m as female and male parents, respectively), and arranged in a completely randomized design with 9 replicated pots, where plants were grown up for 14, 28 and 42 days before harvested serially. Responses of cowpea genotypes to colonization and contribution of mycorrrhizal symbiosis varied greatly. The intensity of plant roots colonized by mycorrhizal fungi was highest on G f , and it was descent on the cowpea hybrids following their generation order. On the other hand, the highest in plant growth response to mycorrhizal function was on G m , followed by G h1 and G h2 . These results indicated that the cross-breed of cowpea and mung bean lines has generated cowpea hybrids that tend to benefit less from mycorrhizal symbiosis for their growth.

“…AMF improve the absorption of P and other nutrients by plants increasing the contact surface and the explored soil volume (Clark and Zeto 2000) and possibly facilitating nutrient transport among plants (Chen et al 2005). Moreover, plants colonized by AMF have alternative mechanisms to meet their nutritional demands and to maintain their physiological functions under abiotic stress conditions, such as drought stress (Ruiz-Lozano et al 2001) and salinity (Azcón and El-Atrash 1997).…”

Communities of P-solubilizing bacteria, fungi and arbuscular mycorrhizal fungi, were evaluated in two different ecosystems. Samplings taken from two areas of Atlantic forest, in Paraty -RJ, Brazil, one with a secondary forest and the other with a grass pasture were studied. Four growth media: GL (glucose and yeast extract), GES (glucose, soil extract, KNO 3 , CaCl 2 , MgSO 4 , NaCl, FeEDTA and micronutrients solution), GAGES (glucose, soil extract, arabinose, glycerol, CaCl 2 , MgSO 4 and NaCl) and GELP (glucose, soil extract, yeast extract, peptone, CaCl 2 , MgSO 4 and NaCl) were evaluated for the isolation of P-solubilizing microorganisms. The identification of P-solubilizing bacteria was based on 16 S rDNA sequence analysis, while the identification of P-solubilizing fungi and arbuscular mycorrhizal fungi was based on morphology. The greatest number of P-solubilizing bacteria was isolated using GL and GELP growth media. The greatest number of P-solubilizing fungi was isolated using GAGES and GES. The bacteria were identified as Enterobacteriaceae and Bacillus sp., while the P-solubilizing fungi were identified as Aspergillus sp. Glomus macrocarpum and Glomus etunicatum were the dominant mycorrhizal fungi in the secondary forest and grass pasture area, respectively.
