Abstract

Tomato is one of the important vegetable crops being cultivated throughout India. Rapid deterioration of stored vegetable seeds is a serious problem which occurs at an increasing rate in uncontrolled storage environment. The present study was aimed at investigating the effects of zinc oxide nanoparticles (nano-ZnO) on tomato seeds during aging. The experimental treatments included four concentrations of nano sized ZnO (400, 600, 800, and 1000 mg/kg), and control (without any ZnO ) on fresh and aged seeds. Results indicated that the highest and the lowest vigour index (1986 vs. 1521) were obtained in 600mg concentration of nano sized ZnO and control treatments,, respectively in fresh seeds. During aging, vigour index was maintained significantly as 995 with 600mg nano sized ZnO treated seeds when compared with control (495). This study shows that employing ZnO nanoparticles could reduce tomato seed deterioration during aging and promote the seed germination.

Abstract

An experiment was conducted to examine the magnitude of genetic diversity and characters contributing to genetic diversity among 35 core elite wheat germplasm from INDIA and CIMMYT under water deficit condition. Principal components (PC) analysis showed that three components explained 67.73 per cent of the total variation among traits. The first PC contribute 38.8 per cent, second PC contribute 17.17 per cent and third PC contribute 11.66 per cent of total variation between traits. The first PC was more related to LSR, DSI, SCMR, RWC, ear weight per plant, harvest index and grain yield. The second PC was more related to plant height, LSR, tillers per plant, biological yield, thousand kernel weight and RWC. Therefore, selection based on first component is helpful for a good hybridization breeding program. Genetic divergence was carried out and grouped genotypes into six genetically distinct clusters. Cluster II genotypes viz., CHIRYA7, HW2041 and PBW502 shows superiority for functional stay green trait by exhibiting low cluster mean for leaf and DSI, and high cluster mean for SCMR, photosynthetic rate, RWC, tillers per plant, ear weight, 1000 kernel weight, biological yield, harvest Index, grain yield per plant and in contrast Cluster IV genotypes are non-stay green and drought susceptible by exhibiting high cluster mean for LSR and DSI. A three dimensional (3D Plot) depicts maximum genetic divergence between HW2041 and CBW38 and CHIRYA7 and HW2033. Stay green trait and all yield attributing traits except plant height can be improved by intermating HW2041 with CBW38 and CHIRYA7 with HW2033 genotypes which result in a highly heterotic hybrid for these traits under water deficit stress in wheat.

Abstract

Flip-flops are the basic building blocks of any sequential circuits which occupy the maximum area in a circuit. So the robustness of the system greatly depends on the reliable operation of the flip-flop. In this work the PowerPC 603 flip-flop is simulated and analyzed to measure its reliability against variations in supply voltage and temperature. Performance analysis has been made by having Power, Delay and PDP as Figures of Merit. The acquired simulation results revealed the different sources of power consumption in different scenarios. The simulated results using finer technologies with Synopsys HSPICE prove that PowerPC 603 is a resilient flip-flop for all corners.

Abstract

Design of an analog circuit depends on several factors such as design methodology, good modeling and technology characterization. This work focuses on designing a high speed (1.6GHz) latched comparator with low power consumption suitable for ADCs in SoC applications. The latched comparator is designed with StrongArm latch as the primary decision and amplification stage followed by a latching element to drive the output load. The StrongArm latch is a proven circuit topology suitable for all seasons. The zero static power consumption of StrongArm latch is exploited to design a low power comparator. The output latch is used to hold the previous output value during the tracking time of the comparator. The designed comparator achieves zero setup time at a clock frequency of 1.6GHz and produces digital output with a maximum delay of 180ps.The comparator is implemented with SAED 32nm technology libraries. The performance has been analyzed using HSPICE simulator.

Abstract

The vulnerability of Cloud Computing Systems (CCSs) to Advanced Persistent Threats (APTs) is significant. So a cloud architecture reference model that incorporates a wide range of security controls and best practices, and a cloud security assessment model - Cloud-Trust - that estimates high level security metrics to quantify the degree of confidentiality and integrity offered by a CCS or cloud service provider (CSP) is used. Cloud-Trust is used to assess the security level of four multi-tenant IaaS cloud architectures equipped with alternative cloud security controls and to show the probability of CCS penetration (high value data compromise) is high if a minimal set of security controls are implemented. CCS penetration probability drops substantially if a cloud defense in depth security architecture is adopted that protects virtual machine (VM) images at rest, strengthens CSP and cloud tenant system administrator access controls, and which employs other network security controls to minimize cloud network surveillance and discovery of live VMs.

Abstract

Trust and security have prevented businesses from fully accepting cloud platforms. To protect clouds, providers must first secure virtualized datacenter resources, uphold user privacy, and preserve data integrity. It is suggested using a trust-overlay network over multiple data centers to implement a reputation system for establishing trust between service providers and data owners. Data coloring and software watermarking techniques protect shared data objects and massively distributed software modules. These techniques Safeguard multi-way authentications, enable single sign-on in the cloud, and tighten access control for sensitive data in both public and private clouds.

Abstract

An experiment was conducted to study the variability and association between characters in rice. 36 genotypes of rice were evaluated and obtain information on variability parameters and correlation analysis for 18 characters. Analysis of variance revealed high significant differences for all the 18 characters studied. Phenotypic co-efficient of variation (PCV) was higher than genotype co-efficient of variation (GCV) for all the characters indicating the little influence of environment on the characters. Number of unfilled grains per panicle had maximum GCV followed by grain yield per plant, harvest index, biological yield per plant, number of filled grains per panicle and grain L/B ratio. All the qualitative characters depicted high estimates of heritability, which indicates preponderance of additive gene action in the inheritance of these characters. High to moderate degree of genetic advance was observed for number of filled grains per panicle followed by biological yield per plant. Grain yield per plant showed positive and significant correlation with number of filled grains per panicle followed by harvest index, biological yield per plant and panicle length at phenotypic and genotypic level. Thus, these characters may serve as effective selection parameters during breeding programme for crop improvement.

Abstract

In this study, a total of eight Burkholderia isolates obtained from rhizosphere soil of maize, cotton, rice, sugarcane, groundnut and soybean and tested for the N fixation, phosphate solubilisation and antagonistic activity against Rhizoctonia solani. All the eight isolates produced the band for the nifH gene in the polymerase chain reaction confirmed the presence of nifH gene. Among the 8 isolates, RMS1 produced clear halo zone around 7 mm on surface of HAP medium. CMS1, RMS1 and SMS1 are inhibited the growth of Rhizoctonia solani for 43, 40 and 35 per cent, respectively. An isolate RMS1 possessed all the three plant growth promoting traits viz., higher phosphate solubilizing ability, antagonistic activity and presence of nifH gene selected for molecular characterization with amplifying and sequencing of 1.46 kb 16S rRNA gene. Based on the BLASTn homology it was found that 16S rRNA sequence of isolate RMS1 having 93 per cent identity with showed 97 per cent homology with Burkholderia thailandensis.

Abstract

Blackgram (Vigna mungo) is fourth important pulse crop of India. Major constraints in achieving higher yield of blackgram are absence of suitable ideotypes for different cropping systems, poor harvest index and susceptibility to pests and diseases. Genetic maps can be constructed based on mapping population. Among the mapping populations, Recombinant Inbred Lines (RIL) is more advantages than others. In the present study, an inter sub specific RIL population was developed by crossing VBN (Bg) 4 x Vigna mungo var. silvestris 22/2 by single seed decent method. A total of 195 RILs were evaluated for 11 biometrical traits. RIL 113 recorded the highest mean for single plant yield (9.90 g) along with more number of pods plant (42.84). RIL 125 recorded the maximum yield of 8.93g per plant along with more number of clusters per plant (17.50) and RIL 131 had single plant yield of 7.99 g along with more number of pods per plant (34.00). RILs with high yield and yield attributing traits can be used to develop high yielding varieties. RILs isolated with specific traits could be used as pre breeding material for the improvement of blackgram.
