Influence of growth regulating chemicals on growth and flowering in Jasmine (Jasminum sambac.Ait.)

Jasmine is an important commercial flower crop in Tamil Nadu. The crop has a main floweringseason during March to October and an off-season from November to February. During thisoff-season, flowering is very poor or there is no flowering in many growing areas. In recentyears, growth regulators are valuable in floriculture for manipulating growth and flowering ofmany crops and hence and attempt has been made to induce flowering during off season usinggrowth regulators in Jasmine in the Floriculture unit of the Department of Horticulture, Facultyof Agriculture, Annamalai University, Tamil Nadu during November, 2016 to February, 2017.The treatment comprises of three concentrations of each of two growth promoting substancesviz., NAA and GA3 and two growth retardants (Cycocel and Maleic Hydrazide). The experimentwas laid out in randomized block design with three replications. Among the various treatments,application of NAA @ 75 ppm (T6) recorded the highest plant height (130.6 cm and 178.5 cm at90 and 180 DAP respectively), number of primary shoots (21.68 and 35.68 at 90 and 180 DAPrespectively), number of nodes (9.86 and 15.89 cm at 90 and 180 DAP respectively) and numberof leaves (1250.0 and 2689.5 at 90 and 180 DAP respectively). Earliness in flowering (26.38DAP) and maximum duration of flowering (171.00 days) was noticed in (GA3@ 150 ppm T3).From the above studies, it is inferred that application of GA3 @ 150 ppm could be recommendedfor enhanced growth and higher flower yield in Jasminum sambac

Effect of sprigging density and foliar nitrogen on the growth of Bermuda grass (Cynodon dactylon L. Pers. x Cynodon transvaalensis)

Turf grasses have been utilized by humans to enhance their environment for more than 10centuries. Aesthetically, lawns enhance the quality of life, contribute to social harmony andcommunity pride, increase property values and compliment other landscape plants. The beautyof any garden largely depends on the greenness of the lawn. The first and foremost criteria fora well establishment and a satisfactory lawn are selection of suitable grass species and methodsof its establishment. Hence, an experiment was laid out to study the effect of different spriggingdensity and foliar nitrogen on the growth and establishment of bermuda grass (Cynodon dactylonL. Pers. x Cynodon transvaalensis) in floriculture unit of the Department of Horticulture, Facultyof Agriculture, Annamalai University, Tamil Nadu during the year 2013-2015. Bermuda grasssprigs were planted in different spacing levels and foliar spray of urea with twelve treatmentcombinations comprising of different levels viz., 10 x 10 cm with 1%, 1.5% and 2%; 15 x 15 cmwith 1%, 1.5% and 2%; 20 x 20 cm with 1%, 1.5% and 2%; 25 x 25 cm with 1%, 1.5% and2%, in factorial randomized block design with three replications. From the results, it wasfound that the earliest spread and ground cover were observed in planting sprigs at closerspacing of 10 x 10 cm in combination with foliar application of nitrogen in the form of urea as2 % for two times at seven and fifteen days after planting

RESPONSE OF ORNAMNETAL ANNUALS TO SALINE WATER IRRIGATION

Availability of fresh water is meager in expansion of gardening in all the countries. In many gardens, farm ponds are utilized for irrigation without analyzing the quality of the water. Alternative sources like ponds can be used for irrigation, but salinity will be a problem. Keeping this in mind an experiment was laid out in completely randomized design with three replications. Salinity was induced by adding NaCl of four different concentrations viz., 0.4 , 0.8, 1.2 and 1.6 % and was irrigated on alternative days on two ornamental flowering annuals viz., Zinnia and Petunia. Twenty days old seedlings were subjected to treatments as per the schedule with a control. Phenological observations viz., plant height, number of branches, number of leaves, earliness in flowering, number of flowers, flower diameter are observed at Initial, 40 and 55 days after sowing. From the results, it was found that plant growth reduced with the elevated NaCl concentration. Saline treated plants had earlier blooming upto 1.2%  and with the incaresed salinity levels, the plants falied to initiate flowering and started withering

An Integrated TCGA Pan-Cancer Clinical Data Resource to Drive High-Quality Survival Outcome Analytics

For a decade, The Cancer Genome Atlas (TCGA) program collected clinicopathologic annotation data along with multi-platform molecular profiles of more than 11,000 human tumors across 33 different cancer types. TCGA clinical data contain key features representing the democratized nature of the data collection process. To ensure proper use of this large clinical dataset associated with genomic features, we developed a standardized dataset named the TCGA Pan-Cancer Clinical Data Resource (TCGA-CDR), which includes four major clinical outcome endpoints. In addition to detailing major challenges and statistical limitations encountered during the effort of integrating the acquired clinical data, we present a summary that includes endpoint usage recommendations for each cancer type. These TCGA-CDR findings appear to be consistent with cancer genomics studies independent of the TCGA effort and provide opportunities for investigating cancer biology using clinical correlates at an unprecedented scale. Analysis of clinicopathologic annotations for over 11,000 cancer patients in the TCGA program leads to the generation of TCGA Clinical Data Resource, which provides recommendations of clinical outcome endpoint usage for 33 cancer types

Investigation of keratinase activity by thermo-alkanophilic Nocardiopsis sp. SD6 isolated from feather waste soil / Subhasish Saha... [et. al.]

The aim of the study was to isolate keratinolytic actinobacteria from feather waste soil, poultry farm soil in Tiruchirappalli and Nammakkal District, Tamil Nadu, India and their keratinase activity were investigated by feather degradation. Totally 91 isolates were obtained from feather waste soil and poultry waste soil samples. Among the 91 isolates, 32 positive isolates were selected after grown on modified starch casein agar (SCA) medium with additional casein. All 32 proteolytic isolates were subjected for casein hydrolysis and four significant isolates were selected based on their growth on basal liquid medium containing chicken feather. The isolate SD6 was tentatively identified one of the best among 4 isolates. The isolate SD6 was characterized by morphological, biochemical and molecular property inducing 16s rRNA analysis based and has been identified as Nocardiopsis sp. SD6 (JF907189). The isolate was grown on modified starch casein broth (SCB). Supernatant from centrifuged culture was examined for protease and keratinase activity. The optimum temperature and pH for enzyme activity for both proteolytic and keratinolytic was found at 50°C, pH 8 respectively. Extracellular keratinase enzyme was separated from the culture supernatant by centrifugation and precipitated with ammonium sulphate (80% saturation) and followed by dialysis using dialysis membrane 150. Native PAGE was performed with the enzyme sample and visible bands were observed after de-staining. Zymogram gel electrophoresis was employed to identify the keratinase enzymes band and three bands in the gel were found with positive keratinase activity

Intramuscular hemangioma of the masseter muscle: a case report

Intramuscular hemangiomas are uncommon neoplasm's arising most frequently in the masseter and trapezius muscle. Due to it's location it is often mistaken for a parotid swelling and rarely is an accurate pre-operative diagnosis achieved clinically. The intra masseteric location also poses special problem in terms of proximity to the facial nerve and the post operative flattening following excision of the masseter muscle. A case of intramuscular hemangioma in a 17 year old girl is presented. Inadequacy of computed tomography scan and cytology in achieving a pre-operative diagnosis and also the treatment modalities are reviewed here. An estrogen receptor and progesterone receptor study has been done to verify the hormonal basis of this tumour
