Abstract:
Arbuscular mycorrhizal (AM) technology is a soil-based fertilization practice for sustainable crop productivity. We evaluated six indigenous Arbuscular mycorrhizal fungi (AMF) strains for their symbiotic response with Piper longum (long pepper), a non-timber forest product holding promise as a commercial crop for its medicinal fruits and roots. Piper saplings were raised in a 10 cm thick sand and soil mix inoculated with various AMF. Under field conditions, plants inoculated with AMF demonstrated better survival (≥80%) than non mycorrhizal plants (58%). Almost all the studied AMF strains increased the plant growth, biomass and nutrient content (N and P) over the uninoculated control. Mycorrhizal inoculation with four AMF species, viz: Glomus fasciculatum, G. clarum, G. etunicatum and G. versiforme greatly enhanced long pepper growth both in the nursery and field conditions.Keywords:

Under greenhouse conditions and Glomus mosseae as applied culture,the influences of growth mediums to the growth of arbuscular mycorrhizal fungi(AMF) and its host plant were studied in pot culture.The results showed that the influences of the black stone powder mixed with 1/3 amount of loam soil(J1) on the growth of AMF and its host plant were the highest.Comparing to other growth mediums treatments,the infection rates of AM fungus in J1 treatment increased by 24.6%～114.1%,number of spores by 12.9%～65.6%,total dry weight of corn by 15.6%～109.2%,and P concentrations by 9.1%～84.6%.The influences of sand mixed with 1/3 amount of loam soil(J5) on the growth of AMF and its host plant were the lowest.This research provided technical parameter for processing of the high quality AM production.

Inoculating with Glomus mosseae and G.versiforme of arbuscular mycorrhizal fungi(AMF) in three phosphorus levels of 20,40 and 60 mg/kg in acid red soil of south China to study the effects of AMF on maize plant growth.The results showed that the plant height and biomass increased.The mycorrhiza promoted the vegetative growth of maize plant.The mycorrhizal colonization rate was highest when phosphorus level was 20 mg/kg.Inoculated with G.mosseae,the plant height and biomass increased most significantly.

A green house study was carried out to investigate the effect of inoculation with four native Arbuscular mycorrhizal fungi (AMF), Glomus mosseae, Glomus fasciculatum, Glomus clarum and Glomus versiforme on growth performance of a medicinally important plant “Long pepper” (Piper longum L.). Inoculation with all AMF species enhanced plant growth, however, signifi cant variation in effectiveness of the four AMF species was observed in relation to both root and shoot growth. A signifi cantly higher total biomass (0.84g/plant) was observed in G. fasciculatum and G. clarum inoculated plants. The performance of G. fasciculatum, G. clarum and G. versiforme were statistically on par to each other in increasing the chlorophyll content over the control plants. The root colonizing capacity of G. fasciculatum was found to be signifi cantly higher, the next being G. versiforme.

Abstract The use of alternative technologies involving biological processes, with economic and ecological gains, is desirable for both the expansion of Musa spp. farming and the renovation of areas with low yields. Arbuscular mycorrhizal fungi (AMF) can stimulate plant growth, especially by increasing the absorption of phosphorus (P) and other nutrients. This study analyzes the influence of AMF on the growth and physiology of micropropagated Musaspp. plants submitted to doses of P. The experimental design was randomized blocks, in a 5 x 5 factorial arrangement, in which the factors were inoculation with AMF (Glomus clarum, Gigaspora margarita, , Gigaspora albida,Clareoideoglomus etunicatum, and the control without AMF) and five doses of P (0, 50, 100, 200, and 400 mg kg-1), with four replicates. The application of P doses increased growth in micropropagated Musaspp. seedlings, regardless of mycorrhizal inoculation. The highest rates of mycorrhizal colonization occurred at the lowest P doses, and the dose of 50 mg kg-1 P provided better conditions for mycorrhizal formation in all AMF species under study. The symbioses with AMF, as well as the use of P, increased photosynthesis rate, thus favoring the growth, development, and quality of Musa spp. seedlings. Species G. clarum, C. etunicatum, and G. margarita were the most promising for plant growth.

The potential for arbuscular mycorrhizal fungi (AMF) to influence the host species depends on their affinities and effects. Twenty three different AMF strains from nearby localities were evaluated for their symbiotic response with Piper longum (long pepper). Saplings were raised in 10 cm thick sand-soil mix inoculated with isolates of different AM fungi. Almost all the studied AMF strains showed increase in plant growth, biomass and nutrient content (NP Glomus fasciculatum, G. versiforme, G. clarum, Glomus sp. 2, G. mosseae and G. etunicatum appeared to be the most promising AM fungi for inoculating this medicinal plant.

一个壶实验被执行决定 arbuscular mycorrhizal 真菌(AMF ) 的效果土壤性质和在在一个温室被用于连续黄瓜单一经营 15 年了的降级的土壤的黄瓜幼苗的生长上的社区。在实验， AMF 社区(由联合被发现在自然农场土壤主导的各种各样的 AMF 种类创造了) 被接种进降级的土壤，然后土壤与黄瓜被种。有 AMF 社区的接种没影响土壤 pH，但是增加土壤总数稳定性并且减少在土壤的盐离子和电的电导率(EC ) 的集中。有 AMF 社区的接种增加了 culturable 细菌和放射菌类的数字，但是减少了真菌的数字。AMF 社区与 non-mycorrhizal 或单个 AMF 相比增加了植物生长，可溶的糖内容，叶绿素内容，和根活动种处理。土壤质量和植物生长的改进与下列二个社区是最大的：血管球 etunicatum + G。mosseae + Gigaspora margarita + Acaulospora lacunosa 和 G。aggregatum + G。etunicatum + G。mosseae + G。versiforme + G。margarita + A。lacunosa。结果建议某些 AMF 社区能实质地改进降级的土壤的质量。

This experiment was carried out to screen the aeroponically grown host plants suitable for the mass propagation of arbuscular mycorrhizal fungi (AMF) inoculum and clarify the effect of P levels in nutrient solution on the growth of aeroponically grown sweet potato (Ipomoea batatas L.), AMF infection, and mass propagation of mycorrhizal spores, etc. Amount of biomass of host plant became higher, as the P levels in nutrient solutions increased from 5 to 20 M. AMF infection rates in mycorrhizal roots increased in higher P levels in nutrient solution, and decreased in lower parts of mycorrhizal roots by about 18.6-26.0%. About 586 mycorrhizal spores per 1 g fresh root were formed at 16 weeks after inoculation of mycorrhizal inoculum. Total of 830,479 mycorrhizal spores were propagated in each plot.
