Effects of slash and burning on soil microbial diversity and abundance in the tropical rainforest ecosystem, Ondo State, Nigeria
This study was carried out to examine the effects of slash and burn on the diversity and abundance of soil microorganisms. Composite soil samples were collected from the study area before burning and two weeks after burning progressively for a period of three (3) months. The bacteria and fungi in the soil samples were isolated and identified. In addition, the pH, soil temperature and soil moisture content of...

Evaluation of cassava varieties for cassava mosaic disease resistance jointly by agro-inoculation screening and molecular markers
The whitefly-transmitted cassava mosaic disease (CMD) has become a potential threat to cassava (Manihot esculenta Crantz) cultivation in ASEAN countries because of its devastating impact on cassava and overgrowth of whitefly vector regionally. To reduce the risk caused by the disease, it is necessary to evaluate the capacity of major cassava germplasms for CMD resistance to guide local farmers in...

Effects of low cost drying methods on seed quality of Sorghum bicolor (L.) Monech
The effect of low cost drying methods on the seed quality of different genotypes of sorghum was investigated. Fresh seeds from five genotypes were subjected to three drying regimes, namely sun, shade and silica gel, and were compared to the standard recommended drying condition using a seed dryer (Munter seed dryer Model M120) as control. The effects of the drying regimes on seed moisture content, viability...

Response of some ornamental flowers of family Ranunculaceae to sucrose feeding
The effect of different concentrations of sucrose on some ornamental flowers of family Ranunculaceae was examined. Sucrose was found to enhance vase life in cut spikes of Aquilegia vulgaris and Consolida ajacis cv. Violet blue; besides it improves blooming, fresh and dry mass of flowers. A. vulgaris and C. ajacisexhibits abscission type of flower senescence, while senescence...

Seed germination and viability in two African Acacia species growing under different water stress levels
Acacia species are important in forestation programs and for producing non-timber forest products in arid and semiarid zones, but few studies have been carried out concerning the effects of drought in the germination in order to understand the regeneration process of the species. In this paper, we studied the morphology and the germination pattern under different water stress of Acacia...

Ecological distribution and feeding preferences of Iran termites
From nine province of Iran, surveyed for wood destroying termites carried out, in 2008 - 2009, sixteen species were collected. Out of the 1050 plants examined in the nine provinces, only 190 were infested by termites. Maximum infestation (22.41%) was recorded in province of Sistan and Baluchestan. Anacanthotermesvagans (Hagen) and Microcerotermes diversus (Silvestri) were more...

Determining genetic diversity based on ribosomal intergenic spacer length variation in Marama bean (Tylosema esculentum) from the Omipanda area, Eastern Namibia
Marama bean [Tylosema esculentum (Burchell) L. Schreiber] is an under-utilized non-nodulating legume, native to the arid and semi-arid areas of Southern Africa, including Namibia, South Africa and Botswana. Its primary benefit to man is based upon the high nutritional value of the seeds. The protein content is slightly higher than that of soybeans and the oil content is twice that of soybeans and...
