Morchella, the true morels, belonging to Helvellaceae family of class Ascomycetes, are amongst the most highly priced fungi in the world. Their artificial production is still a challenge, even though patents for their cultivation do exist. The tissue of Morchella sp. was transferred aseptically to Potato Dextrose Agar medium (peeled, sliced and boiled potato, 200 g; dextrose, 20 g; agar, 20 g L-1) to grow hyphae. The mycelium showed fastest growth as compared to other edible mushrooms. It covered entire area of Petri plate (90 mm) within 4-5 days with the growth rate of 18- 22.5mm/day. A unique growth pattern i.e., vertically oriented mycelia were observed. Brown coloured pigmentation in the culture was also observed during the study. The basal media for spawn (wheat grains; Glucose, 1%, CaCO3, 2%; CaSO4, 1.5% and MgSO4, 1%) was aseptically inoculated with the mushroom culture. The spawn substrate was colonized by mushroom mycelium in 7-8 days. The sclerotia were formed in unused (old) spawn. Wheat straw was used as a substrate for mushroom cultivation. It was supplemented with wheat bran, 20%, Glucose (1%) and MgSO4 (1%). It showed prolific growth when it was seeded by mushroom spawn using jar method. Once substrate was fully covered with mushroom mycelium, casing was applied. Sclerotia were successfully obtained after 14 days of incubation in our experiment both in the substrate and casing soil but failed to give rise to fruiting primordial. Further research is going on to domesticate this species in our country.

Looking directly at the sun can lead to permanent eye injury due to damage of light-sensitive rod and cone cells within the retina. There are two ways to look at the Sun safely: by observing the sun directly through a suitable filter, or by projecting the Sun’s reflection onto a piece of paper via handmade pinhole camera/ telescope. The present correspondence shows the specification for the development of an optical instrument for the direct observation of sun. For this device, commonly available solar control glass plates can be used. The design of this filter is based on the fact that both visible and UV radiation comply with the law of Reflection and Refraction of light. As light rays appeared on the glass plate, most of the rays pass through the glass after refraction. A portion of the incident ray is mirrored and goes out to the next glass panel, where the same thing is going to happen. Through this way, multiple glass plates reflect the light ray before diffuse light is received. Owing to the fact that diffuse reflection is responsible for the ability to see most illuminated objects, we will be able to see the dull image of sun directly through this filter during the solar eclipse.

Aim: The efficient mushroom production involves many factors of which spawn production, culture methods and substrate selection are of prime importance. The research has, therefore, been carried out to standardize these aspects in present communication, for production of Pleurotus florida Strain P1. Materials and Methods: Various cereals (maize, oat, barley) and millets (Italian millets, Little millet, Pearl millet) were assessed against wheat grain spawn for enhancing yield and biological efficiency of mushroom. Most suitable wheat straw component among fine pieces of leaves and leaf sheath (0.2 cm), coarse pieces of leaves and leaf sheath (0.4 cm), small (1.0 cm) and large pieces of the stem (1.7 cm) were also evaluated for the manifestations above. Various culture methods viz., bag, column, wall and tray culture and few substrate mixtures (corncob + wheat straw, mango sawdust + wheat straw and rice husk + wheat straw) have also been taken to increase yield performance of mushroom. Results: The result showed that barley and oat grains produced good quality spawn in terms of quick mycelial running on the grain surface (14 days each). These spawn produced acceleration of spawn running and increased yield, as compared to other types of spawn. When different components of wheat straw were evaluated for the yield performance of mushroom, the course pieces of the stem (1.0 cm) proved the most appropriate component in relation to very low/zero contamination along highest yield (819 gm) and biological efficiency (163.8%). In contrast, wheat straw and corn cob were recognized as the best substrate combination with highest yield (707 gm) and biological efficiency (141.4%) of mushrooms. Among different culture techniques used, only the column method gave significant yield (930 gm) and biological efficiency (186%) with appropriate mushrooms sizes from packaging point of view. Conclusion: The results obtained during the study revealed that by adopting the composite approach, the growers enhance mushroom production in manyfolds. The mushroom is cultivated by following column method. The wheat straw devoid from pieces of leaf & leaf sheath should be utilized as a substrate with corncob combination. It should be inoculated with oat/barley spawn to higher yield.

Bottle culture: A suitable method for oyster mushroom cultivation

Dr. siddhant

Two wastes from animal origin, viz., human hairs and egg shells were evaluated for different manifestations of white oyster mushroom, Pleurotus florida. The mushroom utilized both the substrates for their growth and sporophore formation. The mycelial growth was significantly (P=0.05) faster on egg shell (18 days) as compared to human hair (23 days). The crop of mushroom was harvested in four flushes where human hairs showed higher yield and biological efficiency of mushroom (165 gm, 33%) than egg shells (155 gm, 31%), respectively. In respect of yield parameters such as yield, biological efficiency, number of mushroom fruit bodies and average weight of sporophores, both the substrates were statistically at par to each other. Utilization of human hairs egg shells by P. florida reveals a new strategy for mycoremediation of these wastes.

Eight different kinds of papers, viz., glaze paper, brown paper, news paper, magazine paper, chart paper, kite paper, rough copy paper and A-4 size printing paper, and two types of cardboard viz., corrugated cardboard and card board were evaluated for different manifestations of white oyster mushroom Pleurotus florida Strain-P1. Among them news paper was later treated as a control. The mushroom was utilized all the substrates for their growth and sporophore formation. Majority substrates were taken almost equal time for spawn run, primordial development and fruiting bodies maturation. The measured parameters were net yield (Weight of fresh mushrooms), biological efficiency, number of fruiting bodies produced and average weight of sporophores varied among themselves. The crop of mushroom was harvested in three flushes where yield and biological efficiency ranged 190-495 gm, 38-99% for the substrate used. Magazine paper (450 gm; 90%) and card board (495 gm; 99%) produced significant (P=0.05) yield and biological efficiency over control. They also produced significant number of mushroom fruit bodies (56 and 64, respectively). Corrugated cardboard (10.29 gm) was found significant in terms of average weight per sporocarp. The percentage yield of different substrates was also evaluated. Among the substrates, card board contributed 14% of total mushroom production followed by magazine paper (13%) and news paper (12%).

Aims: Cultivation of oyster mushrooms has increased vastly in a global scale during last few decades. Contaminants and indigenous microflora present in the substrate may led to the low productivity of mushrooms. Keeping this in mind, the present study was under-taken with slight modification in substrate preparation technique to eliminate dust particles from the substrate and to assure contamination free mushroom production. Study Design: Comparative evaluation between modified approach and control beds. Place and Duration: The study was carried out in Shri Laxman Prasad Pyare Lal Agro Products, Ayodhya during 2017. Methodology: The wheat straw substrate was immersed in the drum containing tap water, mixing properly and allowed to stand for 10-15 min to settle down the dust particle in the bottom of the drum. After that, the floating substrate was transferred to the slant surface so that the extra water was decanted off. This substrate was put in to the steam sterilised gunny bag and steeped in the chemical solution consisting of Formaldehyde (500 ppm) and Bovistin (75 ppm) for 18 h. For the Short Communication Siddhant et al.; AJAHR, 2(2): 1-5, 2018; Article no.AJAHR.44907 2 control, fresh wheat straw was put in to the steam sterilised gunny bag and steeped directly in the chemical solution as suggested above. After removal of excess water, the substrate was used for spawning with inoculums of Pleurotus sajor-caju, Strain- Malaysia. Results: Beds with modified approach showed a complete absence of contaminants during entire crop cycle which showed the effectiveness of modified method while beds treated as control showed little incidence of various contaminants viz., Alternaria alternata, Aspergillus fumigatus, Curvularia sp., Penicillium sp., and Rhizopus stolonifer with 6.67-20.00 percent incidence. Conclusion: The results revealed that the modified method should be considered to contamination free mushroom production.

Record of periconia byssoides on four o clock plant from india

Dr. siddhant

Periconia byssoides is known to parasite a number of plants in India but so far not reported on Capsicum annuum L. The small spherical to irregular spots of light brown colour gradually enlarged and merged subsequently to form continuous dark brown to black patches on stem, leaves and fruits. The whole plant were soon infected and ultimately dried within 20-25 days. The damage was about 70-85 per cent. The fungus was isolated on PDA medium by usual methods. The specimen has been deposited (No. RSK-142) in the herbarium of Botany Department, K.S.S. P.G. College, Faizabad. Cited this as: R.S. Kanaujia and R.S. Verma (1979): Periconia rot of Capsicum annuum in India. Indian Phytopathology. 32(3): 445.

In December 1978, the author observed the stored fruits of Citrus reticulata Blanco severely infected by a fungus causing soft rot in local fruit market of Faizabad. The entire fruit surface was densely covered by the fungus causing the rot. The fungus was isolated on PDA medium and identified as Trichoderma lignorum (Tode) harz. In India, T. lignorum has been found on various substrates, viz., soil, rhizosphere region of Pennisetum typhoides, paddy straw of mushroom beds, phyllosphere of Impatiens balsamina and Citrus crysocarpa but not on Citrus reticulata and the present association is a new record for India. Cited this as: R.S. Kanaujia (1979): Fruit rot of mandarin orange. Indian Phytopathology. 32(3):450.

Short hole disease of Alocasia indica Schott, caused by Phoma exigua Desm., earlier unknown to India has been reported from Faizabad. The infection was chiefly confined to the margins of lamina. It started as small nonchlorophyllous spots near the fronds. The spots gradually enlarged irregularly upto 2-3 cm sq. area of the leaf, merged and in final stage, necrosis and then short holes appeared within a month. The pathogenicity tests performed by standard methods proved pathogenic nature of the fungus.

Using deep archival observations from the Chandra X-ray Observatory, we present an analysis of linear X-ray-emitting features located within the southern portion of the Galactic center chimney, and oriented orthogonal to the Galactic plane, centered at coordinates l = 0.08◦ , b = −1.42◦ . The surface brightness and hardness ratio patterns are suggestive of a cylindrical morphology which may have been produced by a plasma outflow channel extending from the Galactic center. Our fits of the feature’s spectra favor a complex two-component model consisting of thermal and recombining plasma components, possibly a sign of shock compression or heating of the interstellar medium by outflowing material. Assuming a recombining plasma scenario, we further estimate the cooling timescale of this plasma to be on the order of a few hundred to thousands of years, leading us to speculate that a sequence of accretion events onto the Galactic Black Hole may be a plausible quasi-continuous energy source to sustain the observed morphology

In recent years, the growth of scientific data and the increasing need for data sharing and collaboration in the field of environmental chemistry has led to the creation of various software and databases that facilitate research and development into the safety and toxicity of chemicals. The US-EPA Center for Computational Toxicology and Exposure has been developing software and databases that serve the chemistry community for many years. This presentation will focus on several web-based software applications which have been developed at the USEPA and made available to the community. While the primary software application from the Center is the CompTox Chemicals Dashboard almost a dozen proof-of-concept applications have been built serving various capabilities. The publicly accessible Cheminformatics Modules (https://www.epa.gov/chemicalresearch/cheminformatics) provides access to six individual modules to allow for hazard comparison for sets of chemicals, structure-substructure-similarity searching, structure alerts and batch QSAR prediction of both physicochemical and toxicity endpoints. A number of other applications in development include a chemical transformations database (ChET) and a database of analytical methods and open mass spectral data (AMOS). Each of these depends on the underlying DSSTox chemicals database, a rich source of chemistry data for over 1.2 million chemical substances. I will provide an overview of all tools in development and the integrated nature of the applications based on the underlying chemistry data. This abstract does not necessarily represent the views or policies of the U.S. Environmental Protection Agency.

Parental care in fishes varies greatly depending on the species. Some species exhibit no parental care at all, with the eggs being left to develop on their own, while others display elaborate forms of care, such as guarding the eggs, fanning them to provide oxygen, or even carrying the eggs in their mouths. These behaviors can enhance the survival of the offspring by protecting them from predators, providing oxygen, and ensuring optimal conditions for development.
