Comparative Response of Salt Tolerant and Salt Sensitive Maize (Zea mays L.) Cultivars to Silicon

[Abstract] [Full-Text PDF] [html]

Abstract: Salinity stress is one of the most devastating stressful environments for plant growth and production. Two Zea mays cultivars, salt sensitive (Trihybrid 321) and salt tolerant (Giza 2), were grown in a complete nutrient solution in a growth room, to investigate the effect of silicon treatment, as Na2SiO3 (2.5 mM) on plants grown at two levels of salinity, 0.0 (Control), 150 mM of NaCl (S) which are equivalent to 15.5 dS m-1 , and supplied to the nutrient solution. Maize plants (Giza 2 and Trihybrid 321) grown at 15.5 dS m-1 show a decreased in the chlorophyll (a+b), carotenoids, total protein contents, transpiration rate, relative water content (RWC), enzyme activity of ribulose-1,5-bisphosphate-carboxylase/oxygenase (RuBPCase), photosynthetic activity ( 14CO2-assimilation) and macronutrient level (N, P, and K) as compared to the control plants. The results indicated that silicon (Si) treatment at 2.5 mM partially offset the negative impacts and increased tolerance of maize (Giza 2 and Trihybrid 321) to salinity stress by enhancing the above parameters. In contrast, salt stressed maize plants considerably increased proline content, Na+ and Clˉ levels, H2O2, malondialdehyde (MDA), and electrolyte leakage (EL). Application of silicon (2.5 mM) decreased significantly these parameters as compared to salt stressed maize plants. Salt tolerant (Giza 2), treated with silicon at 2.5 mM showed better performance than salt sensitive (Trihybrid 321). Salt tolerant (Giza 2), exhibited lower accumulation of Na+ and Clˉ levels, H2O2, MDA, and EL more than salt sensitive (Trihybrid 321). Overall, exogenously applied Si was found beneficial for improving salt tolerance of maize plants.

E-Voting security system through Biometric Cloud Computing Integration with virtual server application

[Abstract] [Full-Text PDF] [html]

Abstract: Today, biometric cloud security creates a new explosion in technology. With the advent of Cloud Computing biometric security and reliability plays important role in national and international e-governments. In e-voting system, if we incorporated cloud based computing through biometrics then it will create more authentication, transparency and security in voting system. To operate e-voting management system requires vast cloud database applications and Big data application to store massive biometric data. In this method helps user to access remotely the voting system through biometric authentication device. Migrating the massive amount of biometric data is difficult. So Virtual server plays important role to reduce the hazards. Cloud computing helps to reduce workload and provide efficient streamlined of security. We will propose a system that reduces the security risk in cloud by various Biometric recognition systems. Physiological and behavioral feature of a person are required in biometrical systems. Physiological biometric includes Fingerprint scan, face recognition, geometry of hand, Iris scan and retinal scan .The main advantage of Biometrics integration with Cloud provide on demand services so organization or Government purchase or rent the infrastructure as required and install it.

Comparison of Heat Retention in Fresh Water and Salt Water Samples

[Abstract] [Full-Text PDF] [html]

Abstract: Heat retention in salt water and fresh water was compared with a view to identifying the one that is best at retaining heat. To achieve this, 150 ml and 100 ml of distilled water at room temperature (29oC) were heated separately to 100 oC (boiling point). Measured values (5g, 10g and 15g) of table salt were each added to 100 ml and 150 ml of distilled water to reach a level of salinity and the solution was heated to boiling point. A cooling system was set up to continuously mix the solution during cooling process to maintain uniform temperature and mercury-in-glass thermometer was used to record the temperature drop at every 10 minutes interval. The graphs of the temperature against time were plotted using Matlab to obtain the cooling rate. The results showed that the salt water has the capacity to retain more heat than the fresh water, and the concentration of salt in salt solution also determines the heat retention ability.

Drip Irrigation Flow Ratio Influence of the Spatiotemporal Distribution of Moisture, Salts and Temperature Related to Root Zone in Sandy Soil Model

[Abstract] [Full-Text PDF] [html]

Abstract: The trials were conducted to estimate the influence of the drip irrigation flow ratio of the spatiotemporal distributions of moisture, salts and temperature related to the root zone, experiments is being designed as a randomized complete block (R.C.B.D), beside three repeats, conducted by applying equal amounts of irrigation water (4 liters) using three flow ratio of drip irrigation systems (F1 = 0.8, F2 = 4 and F3 = 8 l/h) on the sandy soil section model using plexiglass box. And the obtained results are there are significant differences of the spatiotemporal distribution of soil moisture contents, and the more positive significant is F1 = 0.8l/h more over their influence on the spatiotemporal salts distribution clearing the happened leaching of biggest flow F3 = 8l/h according the more applied water amount per time beside, the vertical velocity of water to bottom taking nutrients to drainage conversely, with reducing of flow ratio, flows ratio don’t effect on the spatiotemporal soil temperature distribution. And these are basic considerations must be taken into account when designing and drip irrigation system in the sandy lands of different plants.

Studies on Ethyl Methane Sulphonate induced Desynapsis in ViciafabaL

[Abstract] [Full-Text PDF] [html]

Abstract: Cytological and genetical behaviors of two desynaptic plants induced in Viciafaba L. var. minor by Ethyl methane sulphonate treatment have been studied. Analysis of chromosomal behavior at different stages of meiosis has been thoroughly accomplished in the desynaptic plants. At diakinesis in one plant univalents and bivalents were present while in other multivalents along with univalents and bivalents were also noticed. Bivalents were randomly distributed in one plant while non-random in the other. Abnormalities like univalents, irregular distribution of chromosomes, laggards, stikiness, bridges and micronuclei were also observed at metaphase, anaphase and telophase respectively. Meiotic studies revealed that sterility was due to irregular chromosome pairing but the genetic data indicated that sterility was because of single recessive gene in homozygous condition. The desynapsis obtained during the present investigation fit into the medium strong type.
