Assessing the Genotypic Differences for Seed Set and Seed Abortion in Tomato Genotypes

Tomato (_Lycopersicon esculentum_ Mill.) is one of the most popular fruit vegetable around the world. Seed abortion where in only a small proportion of ovules in an ovary develops into matured seeds, is a wide spread phenomenon in multi-ovulated species. In agriculturally important crops such as chickpea, groundnut, Brassica, pigeon pea and field bean seed abortion substantially reduces their productivity. Tomato genotypes exhibited seed abortion where in only some proportion of ovules developed into matured seeds. Seed abortion in tomato cultivars would increase the cost of hybrid seed production. In this study, we have analyzed 19 genotypes for number of ovules, seed set and seed abortion. Tomato genotypes differed significantly for number of ovules per ovary, seed set per fruit and per cent seed abortion. The ovules, matured seeds and seed abortion ranged from 52 to 412 per ovary; 50.90 to 240.76 per fruit and 6.06 to 24.44 per cent respectively. Strong positive correlation was observed in genotypes with higher number of ovules showed higher percentage of seed abortion

Anthelmintic Activity of Trikatu Churna and its Ingredients

The alcoholic extract of Trikatu churna and its ingredients were evaluated for anthelmintic activity. The dried fruits of Piper nigrum L. (Piperaceae), Piper longum L. (Piperaceae) and rhizome of Zingiber officinale Roscoe. (Zingiberaceae) were powdered and mixed together in equiproportions to get a polyherbal formulation, Trikatu churna. All these three ingredients are spicy, commonly used in our daily diet, also well known for their tremendous therapeutic potential, since from the Vedic period. The alcoholic extract of Trikatu churna and its ingredients were screened for preliminary phytochemical studies and also tested for anthelmintic activity against Pheritima posthuma and recorded the time taken for induction of paralysis and death. Piperazine citrate (10 mg/ml) was included as standard reference and distilled water as control. The results demonstrated that, the extracts of Trikatu churna and its plant ingredients showed the presence of alkaloids, flavonoids, tannins, lignins and steroids, these test samples were also exhibited potent anthelmintic activity, but the highest activity was noticed in Trikatu churna, this might be due to the multifunctional effect of all the three plant ingredients of Trikatu churna. Based on the above results, it is confirmed that, combination of Piper nigrum, Piper longum and Zingiber officinale in Trikatu churna offered promising anthelmintic effect than using the ingredients alone

Magnetic resonance evaluation of intra dural spinal tumors with histopathology correlation

Background: Tumors of the spinal cord or canal constitute approximately 15% to 20% of central nervous system tumors. The differential diagnosis of spinal neoplasms is primarily based on location of the lesion relative to the spinal cord and the age, sex and clinical presentation. The aim and objective of the study was to determine the sensitivity of magnetic resonance imaging (MRI) in diagnosing intra spinal tumors and to correlate findings on MRI with histopathological diagnosis.Methods: This is a retrospective study. The study group included all the patients who presented to our hospital with progressive sensory or motor deficits, para or quadriperesis with or without bladder/bowel Involvement. Only patients with Intra dural lesions such as intradural extra medullary and Intra medullary lesions were included in the study. All the extra dural lesion cases such as vertebral tumors, degenerative/osteoporotic compressions and Trauma related cord compressions were excluded from the study.Results: Of the forty intradural tumors, 28 were extramedullary and 12 were intramedullary. Most of the tumors were located in the cervical and the dorsolumbar spine accounting for more than 50%. The most common tumor encountered in our study was schwannoma (22/40), followed by ependymoma (7/40), meningioma (4/40), astrocytoma (4/40), one each of Hemangioblastoma, Neuroentericcyst and Dermoid cyst. Ependymomas, Astrocytomas and hemangioblastoma were intramedullary lesions and the remaining lesions constituted Intra Dural extra medullary lesions.Conclusions: MRI was found to be a highly sensitive imaging procedure and the method of choice for intradural tumor evaluation and to differentiate extra medullary from Intra medullary lesions. It is not sensitive enough to differentiate the Intra medullary tumors. Nevertheless, definite diagnosis could be made by histopathology only.

Performance Enhancement of MIMO MC-CDMA System employing Cylically Rotated Complete Complementary Codes

Wireless communication needs very high data rate and throughput in order to meet increasing demand for multimedia applications. MC-CDMA technique along with multiple input multiple output (MIMO) technique is used to increase data rate and to reduce the channel impairments. Spreading code plays a major role in CDMA technique, Cyclically rotated complete complementary codes (CRCCCs) are used for spreading which have perfect auto-correlation and cross correlation properties. Bit error rate (BER) can be reduced and have other advantages like high data rate, high throughput, reduced inter symbol interference (ISI) and multiple access interference (MAI). MIMO MC-CDMA system employing CRCCCs is designed and simulation results are shown. DOI: 10.17762/ijritcc2321-8169.150614

Effect of chemicals treatment and fiber loading on mechanical properties of borassus (Toddy palm) fiber/epoxy composites

Abstract: The aim of the present study was to investigate and compare the mechanical properties of untreated and chemically modified Borassus fiber reinforced epoxy composites. Composites were prepared by hand lay-up process by reinforcing Borassus fibers with epoxy matrix. To improve the fiber-matrix adhesion properties, alkali (NaOH), and alkali combined with silane (3- aminopropyltriethoxysilane) treatments on the fibers surface were carried out. Examinations through Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM) were conducted to investigate the structural and physical properties of the Borassus fibers. Tensile properties such as modulus and strength of the composites made by chemically modified and untreated Borassus fibers were studied using a Universal Testing Machine (UTM). Based on the experimental results, it was found that the tensile properties of the Borassus reinforced epoxy composites were significantly improved, as compared with the neat epoxy. It was also found that the fiber treated with combination of alkali and silane exhibited superior mechanical properties as compared with alkali and untreated fiber composites. The nature of fiber/matrix interface was examined through SEM of cryo-fractured samples. Chemical resistance of composites was also found to be improved with chemically modified fiber composites

Effect of land configurations and Pongamia mulch on soil moisture content and yield of yellow pericarp sorghum during kharif

The present work aims to determine the effect of land configurations and Pongamia pinnata mulch on soil moisture content and yield of yellow sorghum during kharif, 2018-19 on sandy clay loam soils of Hyderabad. The experiment was conducted at the College of Agriculture, Professor Jayashankar Telangana State Agricultural University, Rajendranagar, Hyderabad. The treatments included land configurations (Flatbed, Ridge and furrow, Broad bed and furrow, Flatbed + Mulch, Ridge and Furrow + Mulch, Broad bed and furrow + Mulch) and yellow sorghum genotypes (PYPS 101, PYPS 102, PYPS 103 and PYPS 104). Mulch used in this investigation was Pongamia leaf mulch applied @ 6 t ha-1 uniformly at 20 DAS. Soil moisture played a vital role in increasing crop yields in the rainfed regions of the semi-arid tropics. During most crop growth stages, the availability of soil water was increased by Broad bed and furrow + mulch, resulting in increased grain yield by 37 % (1701 kg ha-1) of yellow sorghum over flatbed. Ridge and furrow + mulch were found to be the next best treatment, with a grain yield of 1590 kg ha-1. Mulched treatments of flatbed, ridge and furrow and broad bed and furrow increased the grain yield by 20%, 28% and 37%, respectively, compared to flatbed without mulch. The present study will help in recognizing profitable moisture conservation practices and the role of Pongamia mulch in soil moisture conservation and yield maximization of yellow sorghum

Non-sister Sri Lankan White-eyes (genus Zosterops) are a Result of Independent Colonizations

Co-occurrence of closely related taxa on islands could be attributed to sympatric speciation or multiple colonization. Sympatric speciation is considered to be rare in small islands, however multiple colonizations are known to be common in both oceanic and continental islands. In this study we investigated the phylogenetic relatedness and means of origin of the two sympatrically co-occurring Zosterops white-eyes, the endemic Zosterops ceylonensis and its widespread regional congener Z. palpebrosus, in the island of Sri Lanka. Sri Lanka is a continental island in the Indian continental shelf of the Northern Indian Ocean. Our multivariate morphometric analyses confirmed the phenotypic distinctness of the two species. Maximum Likelihood and Bayesian phylogenetic analyses with ~2000bp from two mitochondrial (ND2 and ND3) and one nuclear (TGF) gene indicated that they are phylogenetically distinct, and not sister to each other. The two subspecies of the peninsula India; Z. p. egregius of Sri Lanka and India and Z. p. nilgiriensis of Western Ghats (India) clustered within the Z. palpebrosus clade having a common ancestor. In contrast, the divergence of the endemic Z. ceylonensis appears to be much deeper and is basal to the other Zosterops white-eyes. Therefore we conclude that the two Zosterops species originated in the island through independent colonizations from different ancestral lineages, and not through island speciation or multiple colonization from the same continental ancestral population. Despite high endemism, Sri Lankan biodiversity is long considered to be a subset of southern India. This study on a speciose group with high dispersal ability and rapid diversification rate provide evidence for the contribution of multiple colonizations in shaping Sri Lanka’s biodiversity. It also highlights the complex biogeographic patterns of the South Asian region, reflected even in highly vagile groups such as birds
