“…Higher yield and uptake of nutrients were also correlated with a higher number of bacteria in rhizosphere soils and colonization of roots by AM (Jones and Sreenivasa, 1993;Singh, 1993, Singh andKapoor, 1998). The results indicated a possible synergism between the organisms of two groups used in this study.…”

“…The results in this study showed significant differences when strains were used in dual combination treatment compared to single inoculations of AM fungus or PSB strains, BAM-4 and BAM-12. Singh and Singh (1993) attributed the enhancement of root colonization by AM fungi in the presence of Mussoorie Rock Phosphate and the microbial inoculants to changes in root morphology and physiology. Profuse proliferation and colonization of mycorrhiza in roots could be due to the synergistic effect with rhizobacteria.…”

The present communication is an attempt to explore the synergistic effect of two indigenous phosphate solubilizing bacteria (PSB) (Pseudomonas fluorescens BAM-4 and Burkholderia cepacia BAM-12) and arbuscular mycorrhizal (AM) fungus, Glomus etunicatum on growth, yield and nutrient uptake of wheat plants grown in nutrient deficient soils in pots amended with tricalcium phosphate (TCP). A significant increase in growth, yield and nutrient uptake of wheat plants was noticed and both strains of PSB interacted positively with AM fungus towards all growth parameters studied. A remarkable enhancement of seed yield was recorded notably by 92.8% and an increase in percent root colonization of AM and PSB population in soil was also recorded with time.

Abstract:In this study, plant growth-promoting rhizobacteria (PGPR) were evaluated as potential biocontrol agents against postharvest pathogens of apple fruits. In vitro bioassays revealed that, out of 30 isolates screened, isolates APEC136 and APEC170 had the most significant inhibitory effects against the mycelial growth of several fungal pathogens. Analysis of 16S ribosomal RNA (rRNA) sequences identified the two effective isolates as Paenibacillus polymyxa and Bacillus subtilis, respectively. The two strains showed greater growth in brain-heart infusion broth than in other growth media. Treatment of harvested apples with suspensions of either strain reduced the symptoms of anthracnose disease caused by two fungal pathogens, Colletotrichum gloeosporioides and Colletotrichum acutatum, and white rot disease caused by Botryosphaeria dothidea. Increased productions of amylase and protease by APEC136, and increased productions of chitinase, amylase, and protease by APEC170 might have been responsible for inhibiting mycelial growth. The isolates caused a greater reduction in the growth of white rot than of anthracnose. These results indicate that the isolates APEC136 and APEC170 are promising agents for the biocontrol of anthracnose and white rot diseases in apples after harvest, and suggest that these isolates may be useful in controlling these diseases under field conditions.

“…It has frequently been shown that mycorrhizal plants are much more efficient than nonmycorrhizal plants in utilizing rock phosphate fertilizers applied to soil (Singh and Singh, 1993;Graham and Timmer, 1985). It is also well established that application of soluble phosphate fertilizers to soils reduces the growth benefits from arbuscular mycorrhizal fungal infection (Powell and Daniel, 1978;Mosse, 1973).…”

The effects of a superphosphate (SP) and a rock phosphate (RP), with equal total P contents, on the growth and mineral nutrition responses of mycorrhizal and nonmycorrhizal cowpea, pigeon pea and groundnut were investigated in a pot experiment using an air-dry gamma ray-sterilized (1.5Mrad) Andisol subsoil. Adequate amounts of micronutrients were added to the pot soils as supplements. The plants were inoculated with surface-sterilized 100 spores/pot of Glomus etunicatum or none and with Rhizobium strains. At their maturities, dry weights of plant parts and nodule number, root length, arbuscular mycorrhizal fungal (AMF) colonization of roots and AMF spore production were also measured. Shoot nitrogen and phosphorus concentrations were determined by the Micro-Kjeldahl distillation and ammonium-molybdenum blue methods, respectively. Shoot copper and iron concentrations were measured by the atomic absorption spectrophotometry. Mycorrhiza formation was greater with superphosphate than with rock phosphate treatments. Rock phosphate enhanced mycorrhization in cowpea and pigeon pea but it decreased it in groundnut. Superphosphate-treated cowpea and pigeon pea plants were larger than RP-treated plants whether mycorrhizal or not but in groundnut growth increased only when the plant was treated with SP and inoculated with AMF. Mycorrhizal enhancement of shoot growth in superphosphate-fertilized groundnut could be a direct consequence of improved P nutrition resulting from increased hyphal uptake and/ or enlarged absorptive root surface due to increased root fineness. There were similarities in shoot dry matter yields as well as shoot P uptakes of both mycorrhizal and non-mycorrhizal RP-treated plants suggesting that the legumes were so unresponsive to the RP that even mycorrhization could not trigger any response in them. The increased contents of N, Cu and Fe in the shoots of mycorrhizal SP-fertilized plants were observed to be the result of larger shoot sizes except with Fe in groundnut shoot whose enhancement could be related to a good mycorrhiza formation and a concomitant improvement in P nutrition which may further have been influenced by its fine root structure. There was a very close interdependency of fine root structure, AMF colonization, AMFspore production and improved P and Fe nutrition in groundnut as a result of soluble phosphate application.
