Ecological effects on the flowering phenology of Cenchrus ciliaris L. collections from the arid and semiarid lands of Kenya
Flowering is critical in plant ecology. Through flowering, plants evolve into new plant species that are better adapted to environmental variations. Cenchrus ciliaris is an important forage grass in Kenya, which is drought tolerant but is increasingly becoming depleted in grazing areas requiring reseeding. To identify suitable germplasm for such initiatives, collections from varied ecologies were evaluated at Kiboko to...

Gas exchange and carbon metabolism in young plants of muruci (Byrsonima crassifolia L.) submitted to water deficit
The Byrsonima genus covers various fruit species known in the Brazilian Amazon as murucizeiro, which is considered as a species with good nutritional quality and features in its composition a variety of volatile compounds. The adaptation of plants to water stress is a complex physiological and biochemical phenomenon. Depending on the intensity and duration of stress, changes ranges from a rapid change in the flow of...

Carbon dioxide enrichment studies: Current knowledge and trends in plant responses
Atmospheric CO2 concentrations are increasing and studies about the impact on plant species’ responses are on the rise. Unfortunately the wide range of variations in the published data is a concern when it comes to usefulness and application. Simple descriptive analyses on the published results are needed to make sense of the overall trends in plant responses to CO2 enrichment. In the present report, 90 articles...

Physiological quality of habanero pepper (Capisicum chinense) seeds based on development and drying process
The objective in this research was to study the physiological and biochemical alterations in habanero pepper during the development and after the natural and controlled drying. The experiments were conducted at Seeds Laboratory and in the experimental area of Agriculture Department at Universidade Federal de Lavras (UFLA). The fruits were harvested in four stages of development, being these E1-49, E2- 56, E3- 63 and E4-...

Comparative study on cross-compatibility between Camellia sinensis var. sinensis (China type) and C. sinensis var. assamica (Assam type) tea
Tea has long been a well-known crop for its economic value and widening the genetic variability of tea family is often necessitated. Hybridization programs at intraspecific level have been greatly fascinated as potential and useful methods in tea plant breeding to widening the genetic diversity. This comparative study was intended to explore a new avenue to develop the tea plant breeding programs through evaluating...

Viability of maize pollen grains in vitro collected at different times of the day
The viability of pollen grains is the essential precondition for obtaining enhanced or hybrid vigor genotypes and a good fixation of the fruit. It is a matter of great importance, especially for genetic improvement programs, which are used in various types of controlled pollination. This study aimed to evaluate the viability of the maize pollen grain through in vitro germination and stainability tests, collected at...

Efficiency of optimal pheromone trap density in management of red palm weevil, Rhynchophorus ferrugineus Olivier
The red palm weevil (RPW), Rhynchophorus ferrugineus Olivier is an invasive, hidden pest of date palms causing significant economic losses in Middle East. Mass trapping of weevils with synthetic male aggregation pheromone and food baited traps has been an important component of Integrated Pest Management (IPM) program against RPW. As the viability of pheromone trapping system depends on the optimum trapping density,...

Optimization of culture media for Desmodium incanum micropropagation
Desmodium incanum DC., popularly known as pega-pega, is a wide spread leguminous plant in fields in the state of Rio Grande do Sul in Southern Brazil and is well accepted by the cattle as forage. However, its forage potential is currently threatened, due to the replacement of natural grasslands by agricultural crop and grazing lands and because of the poor pasture management associated with high stocking rate, making it...

Striga hermonthica reduction using Fusarium oxysporum in Kenya
The biological control agent Fusarium oxysporum f.sp. strigae isolate Foxy 2 had shown potential as a biological control in West Africa, however it failed to achieve the same results when used on Kenyan Striga hermonthica. A F. oxysporum isolate FK3 was obtained from infected S. hermonthica in a maize crop in Kenya and tested as a potential control agent of S. hermonthica in Kenya. Two pot trials were conducted where...
