Center of genetic diversity and dissemination pathway in adzuki bean deduced from seed protein electrophoresis

Genetic diversity center plays important roles in collection of germplasm resources. To better understand the genetic diversity of adzuki bean (Vigna angularis L.), seed protein of 198 local strains collected  throughout China and Japan were analyzed by SDS-polyacrylamide gel electrophoresis. Four protein types were identified and the frequency of each protein type strain showed a clear geographical cline. The...

Supply response of beef farmers in Botswana: A Nerlovian partial adjustment model approach

In this study, an attempt has been made to examine the supply response of beef farmers in Botswana by using the Nerlovian partial adjustment model. The short run price elasticity was 1.511 while the long run elasticity was 1.057. This is a clear sign that price policies in Botswana are effective in obtaining the desired level of output for beef. Moreover, in the future, price increase need to be adopted as a strategy...

Effects of nitrogen and light intensity on tomato (Lycopersicon esculentum Mill) production under soil water control

Light, water and nitrogen supply are important factors affecting crops production and growth. To evaluate the effect of different light intensities and nitrogen supply levels with different soil water content on the production of tomatoes, a pot experiment was conducted on the Zijingang campus of Zhejiang University in Hangzhou, China, during the tomato-growing season in 2009. Results showed that the higher the light...

Comparison of a gas fired hot-air dryer with an electrically heated hot-air dryer in terms of drying process, energy consumption and quality of dried onion slices

Onion slices were dried in either a gas-fired hot air dryer or an electrically heated hot air dryer at air temperatures of 50, 60 or 70°C, and at air flow velocities of 0.5, 1.0 or 2.0 m/s. Records of the drying rates and energy consumption were kept by using electronic weighing balances and an electric metering device. The results showed that the drying rate and final product quality in the two dryer were not...

Acute toxicity and histological changes in gills, liver and kidney of catfish, Heterobranchus bidorsalis exposed to cypermethrin concentration

Fingerlings of Heterobranchus bidorsalis (mean weight 11.88 g) were exposed to various sub-lethal concentrations of cypermethrin (0.032, 0.034, 0.036, 0.038 and 0.040 ml/L), a toxicant, and the histological effects were recorded. The 96 h bioassays were also conducted to determine the lethal concentration (LC50) of cypermethrin on the test fish. The 96 h LC50 of H. bidorsalis exposed to...
