Plants used in traditional medicine in Bukoba Rural district in Tanzania were evaluated for their in vitro antimicrobial activities. Plant materials from eight plant species (Harungana madagascariensis (Lam) Poir., Jatropha curcas L., Lantana trifolia L., Plectranthus barbatus Andr., Pseudospondias microcarpa Engl., Psorospermum febrifugum Spach, Teclea nobilis Del. and Vernonia adoensis [Warp....

The leaf essential oils of six members of the Annonaceae from Monteverde, Costa Rica (Desmopsis bibracteata, Desmopsis microcarpa, Guatteria costaricensis, Guatteria diospyroides, Guatteria oliviformis, and Unonopsis costaricensis) have been obtained by hydrodistillation and analyzed by GC-MS in order to compare and contrast the volatile chemical compositions of these species. The essential oil...

This study was conducted in the laboratories and greenhouses of Eastern Mediterranean Transitional Zone Agricultural Research Institute between 2018 2020 to identify botanical characteristic PCPM (Prunus cerasifera X Prunus microcarpa), which is natural hybrid (PC) microcarpa (PM), investigate slip production opportunities it at different IBA 1000 mg L-1, 2000 3000 4000 L-1. noticed its environ...

The application of Cd inhibited the development of mycelia of the saprobe fungi Fusarium concolor and Trichoderma koningii and the hyphal length of the arbuscular mycorrhizal fungi Glomus mosseae and G. deserticola in vitro. The application to soil of 25 and 50 mg l–1 of Cd decreased the shoot dry weight, the percentage of AM root length colonization and the succinate dehydrogenase activity of ...

Background Eucalyptus is grown in around 3.9 Mha in India. Leptocybe invasa Fisher & La Salle (Hymenoptera: Eulophidae) has emerged as a serious pest in Eucalyptus causing considerable loss of quality planting materials besides loss in productivity and quality of timber. Current strategies for its control include selected deployment of Eucalyptus clones tolerant to the pest resulting in several...

A small but intense eucalyptus research effort began in Florida in 1961 with the private, nonprofit Florida Forests Foundation dedicated to investigating the commercial forestry potential of exotic hardwoods in south Florida. By 1965 we had established numerous eucalyptus experiments, including 14 screening trials testing a total of 156 seed sources representing 67 eucalyptus spe­ cies. The Fou...

The kinematics of an arresting-hook unit are studied in order to determine, within the limits of the assumption of a perfectly rigid hook unit, the damper force necessary to control hook bounce. The necessity for a smooth deck and the desirability of small trail angle for the hook unit are demonstrated from several aspects. The design requirements for a hook damper unit are discussed in all the...

Subsurface hook formation during initial solidification in the continuous casting mould degrades the quality of steel slabs owing to the associated entrapment of argon bubbles and non-metallic inclusions. To minimise hook depth and to improve slab quality, extensive plant experiments were performed and analysed to quantify the effect of casting parameters on hook characteristics using the no. 2...

BACKGROUND AND AIMS Plastic responses to stress in components of reproduction can have important effects on plant fitness and can vary both within and between species. Responses may also depend on when in the life cycle stress occurs. Here, it is predicted that the timing of initiation of a stress, defoliation, would affect the pattern of plastic responses. These differences should occur becaus...
