Effects of Arbuscular Mycorrhizal Fungi on Spores Density and Root Colonization of Four Hybrids of Sunflower (Helianthus annuus L.) at Different Rock Phosphate Levels

Sayeda Sarah and Muhammad Ibrar

...her P doses declined the sporulation and colonization. There was total seven AMF species that were observed and recorded. The dominant genus was Acaulospora which was followed by Glomus, Sclerocystis and Gigaspora. The average AMF spore density ranged from 56-260 spores/100g soil while root colonization ranged from 32-100%. Mycorrhizal enhancement regarding AMF spores density and root colonization ranked asRP0>RP1>RP2>RP3 in all hybrids i.e 0%>25%&...

... minimum spots per leaf, sporulation, and product of spots per leaf and sporulation, spots per leaf and percent area diseased per leaf and spots per leaf and defoliation indices. Correlation between defoliation and spots per leaf are negative in Virginia (-0.12 to 0.22) and Spanish (-0.39 to 0.01), whereas positive in Valencia (0.17 to 0.78) were calculated. While positive correlation between multiple of spots per leaf and <...

Arbuscular Mycorrhizal Fungal Spore Density and Root Colonization in Weeds of Carrot field at Charsadda, Pakistan
...was investigated for the sporulation and root infections types. From the recorded results the highest spore density was found in Melilotus indica having spore number 276 which is followed by Malva neglecta and Sonchus asper having spore number 244, 214 respectively. The lowest spore density was recorded in Pao annua having spore number 35. The maximum Glomus density was found in Melilotus indica having mean value (83.67±1.65) whereas the maximum spore d...

...;m). The best growth and sporulation of P. infestans revealed on Rye agar media compared with other media, while the minimus growth was observed on carrot agar media across most isolates. Therefore, the determination of morphological characteristics for plant-pathogen may add knowledge of the taxonomic behavior of pathogen. The usage of various growth media is providing a useful pattern of the growth that can be utilized in determining the best possible contro...
Synthesis, Characterization and Investigation of the Anticoccidial Activity of New formulation Curcumin - Olive Oil Nano-Composite

... and 36 h. Percentage of sporulation inhibition in oocysts and comet assay were used to investigate the C-Oo.Nc destructive effects. The infectivity of sporulated oocysts exposed to LC50 & LC90 were evaluated by In vivo inoculation of broiler chicks. The results demonstrated that the increase in the rate of sporulation inhibition is directly related to the increase in C-Oo.Nc concentrations and exposure time. Analyzing t...
Proteolytic activity analysis in germination defective spores of Bacillus

Uqba Mehmood

... Bacillus species during sporulation and germination. The hydrolysis of spore proteins to free amino acids, is accomplished by proteases, in first 20 minutes of spore germination. The analysis of Spo mutants (strains which lack Sporulation (Spo) gene or have its inactive form) revealed that many of these strains did not produce extracellular proteases. Some evidence for the involvement of serine proteases in
Optimization of sporulation conditions of Bacillus sublilis as potential probiotics strain

MUHAMMAD SHRAFAT ALI1, UZMA HAMEED2* & IKRAM-UL-HAQ3

...tudy, conditions for the sporulation of Bacillus subtilis, a probiotic strain, are optimized. Overnight grown inoculum (1%) was used for the cultivation of B. subtilis in NB medium followed by 24-48 hours incubation in a shaking incubator at 30°C. Spore staining and microscopy were performed at different time intervals to find out the sporulation status and time required for the completion of spo...
Reaction and Diversity Analysis to Identify Novel Genetic Resources for Exserohilum turcicum Resistance in Maize

...in yield, while PC4 with sporulation (spores/ml). Inbred lines were divided into three groups using cluster analysis, with 27 inbred lines being placed in cluster II. The mean values of the disease parameter were found to be the lowest in Cluster II, while the grain yield was the greatest. Cluster analysis showed the highest inter-cluster distance between cluster II and cluster III (4.19) and the lowest between cluster I and cluster III (2.24). Clusters I and ...
