The present study deals with the succession of fungi on the root regions of living Pennisetum typhoides (Burm f.) Stapf. et Hubb. from July to November of 1970 and 1971. A clear succession of fungi from nonrhizosphere - rhizosphere - cortical portion of rhizoplane - steler portion of rhizosplane has been observed. The fungal population and number of species in the crown, middle and distal regions of roots in above mentioned four regions also exhibited a definite pattern. The presence and amount of amino acids and sugars in root exudates (July to October)...

Studies on certain aspects of root surface fungi II. Succession of fungi on decomposing Pennisetum typhoides (Burm. f.) Stapf et Hubb.
Sixty seven fungal species from the nonrhizosphere (NR), rhizosphere (RS) and cortical (RPC)and steler (RPS) parts of rhizosphere of crown (RC), middle (RM) and distal (RD) regions of decomposing roots of Pennisetum typhoides (Burm.f.)Stapf. et Hubb. were isolated during December to June, 1970-72. The number of fungal species gradually decrease from NR-RPS in horizontal and RC-RD in vertical regions. The fungal population was always higher in RS of different depths than in corresponding NR region. The amino acids and sugar component of the roots showed a direct correlation with the fungal population. The...
Studies on certain aspects of root surface fungi. III. Effect of Harvesting
The effect of harvesting of above ground part on the succession of fungi on crown, middle and distal regions of decomposing roots of Pennisetum typhoides (Burm f.) Stapf et Hubb. was investigated for a period of six months (January to June 1971). The number of fungal species was generally lower in harvested plants than in standing plants whereas the fungal population exhibited reverse trend. The amino acids, sugars, cellulose, hemicellulose and lignin components of the root in different vertical regions were assessed and a correlation was established between the above factors and fungal succession...
Survey of Fungi from Archaeological Digs at Faizabad
A study of the fungi from the soil of 8.5 m deep archaeological digs- differentiated into 18 strata- at Katra in Ayodhya of Faizabad district (U.P.) has been made. A total of 23 different fungal species were isolated from 18 different strata of the digs. The upper stratum (0.0-0.23 m) was found to harbour a greater number of fungi, which decrease in quality and quantity towards the lower profiles up to 4.5-5.35 m and finally to nil. The greater no of fungi in upper strata may actually be attributed to organic matter content governing...
Parasitic Fungi of Faizabad, Alternaria
Thirty four species of Alternaria have been recorded on different plants at Faizabad. Several plants were parasited by the same species, on the other hand more than one species have been observed on the same host. Amongst total species, Alternaria tenuis was harboured by 46 plants, A. tenuissima, A. brassicae, A. cucumerina and A. solani had their lesser number whereas 23 species were restricted to only one host separately.

Distribution of Fungi, Bacteria and Actinomycetes in relation to cropping pattern
Eight soil samples from closely situated cultivated field with varying cropping patterns have been assayed for fungi, bacteria and actinomycetes. The microbial population in different plots differed to a considerable extent. Plot with thick coverage and short term cropping pattern gave high fungal counts. The availability of substrates for microbial growth seems to be an important factor in governing the soil microbial population. A marginal difference in moisture content and pH plays a negligible role in the determination of soil microflora. (PDF at Slideshare.net) Cite this as- Kanaujia R.S. and Singh C.S.

Somaclonal Variation: A new dimension for sugarcane improvement
Plant tissue culture or micropropagation technique is the rapid method to multiply newly released cultivar in limited time. Crop improvement by conventional method in vegetatively propagated crops like sugarcane is very difficult due to its narrow genetic base and other limitations. Somaclonal variations are easily achieved in asexually propagated crops like sugarcane and banana. Tissue culture derived variations are known as somaclonal variation. These variations play an important role in crop improvement program. Genetic variations are heritable in next generation and important for crop improvement, epigenetic changes are temporary ultimately reversible. Mutation breeding...

बासी गन्ने मे शर्करा क्षरण को कम करने मे उपयोगी रसायनों पर अध्ययन
गन्ने से अधिक से अधिक मात्रा मे चीनी प्राप्त करने के लिए गन्ना वैज्ञानिकों द्वारा अनवरत प्रयास किये जा रहे हैं। कटाई के उपरान्त, कटाई तथा पेराइ के मध्य के अन्तराल (स्टेलिंग) के कारण गन्ने की गुणवत्ता मे कमी आती है जो शर्करा के इंवर्जन के फलस्वरूप होती है। अतः स्टेलिंग के कारण चीनी परता मे होने वाली हानि से बचने के लिए गन्ने की जल्दी से जल्दी पेराई कर लेनी चाहिए। इस प्रकार की हानि से चीनी उद्योग पर विपरीत प्रभाव पड़ता है। यदि स्टेलिंग से 0.1 यूनिट चीनी कम बनती है...

BRACKET FUNGI: A GROWING MEDIUM FOR OYSTER MUSHROOM
According to a worldwide survey, about 90 kinds of wastes have been proven to be useful for oyster mushroom growing, among these, wastes such as cereal straw, saw dust and wood logs can be re-divided into at least 100 individual type of waste linked to different plant species. It means that in fact a range about 200 different wastes are available as oyster mushroom substrates (Poppe, 2004). Most of these wastes have a C/N ratio between 32 and 600 and a pH 5.0 and 7.5 (Poppe, 2000). A lot of work has been...

Successful cultivation of Blue oyster mushroom in Faizabad, Uttar Pradesh
Blue Oyster mushroom often grows in clusters on living elm trees or elm logs in forest and thus also called elm oyster. Its scientific name is Hypsizygus ulmarius where "Hypsi means "High" or "on high" and "zygus" means a "yoke" thus Hypsizygus ulmarius referring to the position of this mushroom often high in the tree. The fruiting body of elm oyster are larger, heavier and white to bluish grey in colour. It has a stipe that is off center to nearly central. Its gills are attached to stipe but unlike oyster mushroom it...
