Opis:
An experiment was carried out with endophytic fixing bacteria Azospirillum brasilense and Pseudomonas fluorescens isolated from brinjal, in different combinations with inorganic fertilizers by seed inoculation of brinjal to observe preliminary vegetative growth at 15th and 30th day and pigment contents in vegetable nursery bed (proplates). A total number of 28 endophytic bacteria isolated from brinjal from three localities (Annamalai University, Karaikal and Putthur). Further the isolates were subjected to various biochemical tests for their species level identification and nitrogen fixing ability was estimated. Based upon their N-fixing ability and IAA production, two strains, one Azospirillum sp. and one Pseudomonas sp. isolate was selected and tested for its performance in brinjal. The seeds treated with 75% Chemical fertilizer + Azospirillum brasilense + Pseudomonas fluorescens (T6) showed maximum plant vegetative characters, followed by others compared with control.

Opis:
A considerable number of bacterial species are able to exert a beneficial effect upon plant growth. Mostly they are associated with the plant rhizosphere, so they are called as rhizobacteria. Phosphorus is an essential element for plant development and growth making up about 0.2 % of plant dry weight. Several scientists have reported the ability of different bacterial species to solubilize insoluble inorganic phosphate compounds, such as tricalcium phosphate, dicalcium phosphate, hydroxyapatite, and rock phosphate. Detection and estimation of the phosphate solublization ability of microorganisms have been possible using plate screening methods. Phosphate solubilizers produce clearing zones around the microbial colonies in growth media. In the present investigation a total number of fifteen phosphate solubilizing bacterial colonies isolated from different paddy soils in Cuddalore district of Tamilnadu, India. The isolated PSB were identified and characterized for effective use in the field. All the PSB isolates were identified as Bacillus species and designated as P with serial number from 1 to 15. Among the fifteen isolates, the PSB isolate P6 showed highest amount of phosphate solubilization. The quantity of available phosphorus estimated in the P6 grown Sperber broth culture medium on 7th day was maximum of 321.7 μg/ml which was the highest value compared to other PSB isolates.

Opis:
In recent years, the demand of chilli has tremendously increased due to its attractive market price and multifarious used in cooked and processed forms. At present people are much concerned about the fruit quality and yield. Therefore, attention is being paid for development of genotypes having high yield potential with desirable fruit quality characters in a short period of time. For this purpose, seeds of chilli were mutagenised with ethyl methane sulphonate (EMS) and diethyl sulphate (DES) to determine their mutagenic sensitivity in M1 generation. The increasing concentration of EMS and DES decreased in morphological and yield characters. The spectrum of mutation and induced variability for various quantitative traits were observed in M1 generation such as germination (%), plant height, primary and secondary branches per plant, days to first flowering, fruit length (cm), fruit girth (cm), total number of fruits per plant, number of seeds per fruit, seed weight per fruit (g), 100 seed weight (g) and pericarp: seed ratio showed variability in chilli with the effect of EMS and DES. The percentage of chromosomal abnormalities in different mitotic stages was significantly higher than that of the control in all the treatment concentrations.

Opis:
The present study was under taken in order to analyze the chemical mutagenesis on Chilli germplasm. In this regard, K1 variety of chilli was subjected to different mutagenic concentration for inducing mutagenesis. The M3 plants exposed to EMS and DES to produce clear difference from the untreated control, thus indicating that mutagenic treatment produce polymorphic regions in the chilli. For extraction of genomic DNA was adopted an improved protocol of CTAB method with slight modification. A total of ten primers were used to screen the polymorphism among the treated populations line tall, tall with chlorophyll deficient, leaf, flower, GMS and DNA damages in maturity mutants were analyzed with control. Out of ten primers, four primers (PGF02, PGF03, PGF04 AND OP107) were successfully amplified in all the samples used for this study. The successful primers were amplified in to 93 products showing an average of 9.3 bands.

Opis:
The paper describes the noise monitoring data acquired from the pilot project on the establishment of National Ambient Noise Monitoring Network (NANMN) across seven major cities in India for continuous noise monitoring throughout the year. The annual average Lday (06–22 h) and Lnight (22–06 h) values observed in year 2011–2014 for the 35 locations under study in which 14 locations are in commercial zone, 5 in Industrial, 7 in residential and 9 in silence zones are described. The long-term noise monitoring shows that ambient noise levels have marginally increased for 29 sites (82.9%) since past four years. The present study is focused on evaluation and analysis of environmental noise pollution at 35 noise monitoring sites in seven major cities of India and shall be instrumental in planning for the noise abatement measures for controlling the noise pollution in these sites.
