Abstract

To find out the best sources of nutrients for the fungal growth, different solid media were tested. Maximum radial growth was recorded on PDA and Czapek's agar with mean colony diameter of 90mm and on par with each other compared to other media tested. Carrot agar recorded maximum number of sclerotial production (48 per microscopic field) followed by PDA (46 per microscopic field) and the minimum sclerotial production was observed in Czapek's agar (39.33 per microscopic field). PDA and carrot media supported good mycelial growth and sclerotia production. The maximum sclerotial size was observed in PDA (0.5×0.4 μm) whereas Czapek's agar recorded minimum size of sclerotia (0.3×0.2 μm). Ellipsoidal shape of sclerotia was observed in Czapek's agar whereas, irregular shaped sclerotia were observed in other media. Maximum dry mycelial weight was recorded eighth day of incubation (150mg).

Abstract

An experiment was carried out to assess the crop loss due to sunflower leaf curl virus (SuLCV) disease. The crop loss assessment in terms of growth and yield components was recorded at first appearance of symptoms of SuLCV at 30 days to 90 days during the crop growth. The SuLCV disease infection in sunflower significantly affected the plant height (72.60 to 157cm), size of the head (8.60 to 18.78cm), 100 seed weight (2.20 to 6.32g), oil content (31.24% to 38.26%), and weight of seeds/10 heads (77.20 to 372.2g) as compared to the healthy control plants. In the plants, first appearance of symptoms at 30 DAS was recorded the seed yield loss of 79.25 per cent.

Abstract

In earlier days, the customer retrieved library materialized structured information are difficult due to enormous database acted in particular location. This paper deals the privacy and security concern includes threats, attacks, data integrity, data leakage, data availability, loss of control, vulnerability and flaws during distribution of services, resources and information. This technique verifies customer verification and validation between cloud clients and cloud providers. Storing the library information system in digital manner is essential through cloud technologies. As an outcome, library consumers can access resources from outside of physical library using cloud methods. This proposed method enforces the use control and access log technique to reduce the data leakage, improve the efficiency and user privacy of the confidential information. It evaluates the several challenges and issues of cloud such as user authentication, data availability, data confidentiality in a cloud environment. This paper depicted the various investigation reports and reviews of various researchers on electronic digital information based library and its resources by cloud methods and storages. This system provides a scheme of a cloud storages functional construction for building knowledge based digital library. Client’s confidential data are stored in global data center storage and numerous local data centers through redundant array of independent disk method in this cloud environment that leads to recovery from the user control and data leakage. This new innovative flexible system delivers the combination of methods like multi-level security with data availability on dissimilar storages, encryption and decryption technique with customer verification and validation method. The electronic digital library resources and services create novel development in scheme of multiple storages with respect to information access and distribution of confidential data in cloud. The multiple cloud storage architecture for digital electronic library offers data handling, speedy transmission of information and linking of communication among library patrons and cloud providers. It will endorse the maturity level from official level members to higher administrate that meet user request and identify the defensible development of knowledge based digital library system. This capable digital library system maintains the cloud computing environment with better performance evaluation. This functional structure progressively established electronic digital library knowledge management by means of user participation. This digital library using multiple cloud storage implementations creates well organized data integration, reduced cost, accessible any-where at any time of services and resources, scalability, elasticity and portability. Furthermore, cloud security and privacy enquiries know the ability of the adaptable digital library system using cloud computing techniques and extent abundant effectiveness with protected cloud environment.
