An efficient, simple, and rapid regeneration system was established for bananas (Musa sp.) using sections of corm containing intercalary meristematic tissues as explants. Six different cultivars of banana (‘Mpologoma’, ‘Nakitembe’, ‘Mbwazirume’, ‘Pisang awak’, ‘Sukali ndiizi’, and ‘FHIA-17’) with...

Shoot regeneration via organogenesis was achieved from axenic cowpea [Vigna unguiculata subsp. unguiculata L. (Walp.) Verde.] hypocotyls and cotyledons of advanced breeding lines and varieties. Cotyledons and embryos were excised from green immature pods. The apical parts of the embryos were remo...

Medicinal plants are the most important source of life saving drugs for the majority of the world's population. The biotechnological tools are important to select, multiply and conserve the critical genotypes of medicinal plants. In-vitro regeneration holds tremendous potential for the production...

We discuss the main ecological factors that influence tree recruitment in neotropical moist-and wet forests within the context of timber management based on selective logging. We argue that setting aside protection areas in managed forests as a way to preserve ecological processes may not be suff...

Fire, grazing, browsing and tree cutting are major anthropogenic determinants of vegetation patterns in African savannas. In Burkina Faso forest management policies prohibit grazing while recommending annual early fire and selective tree cutting of 50% of the merchantable standing volume on a 20-...

This paper analyses the underlying causes of secondary forest formation and recovery in India, particularly the Western Ghats region of south India, from precolonial times to the present. In the pre colonial period, hunter gatherers, shifting cultivators and settled cultivators were the dominant ...

To determine the regeneration dynamics and growth rate of mahogany in the natural tropical forests of Quintana Roo, oral histories were used to find essentially even-aged stands that had become established naturally between 2 and 75 years ago, after a hurricane, forest fires, or mechanical distru...

To mimic catastropic disturbances which have favored the establishment of natural stands rich in mahogany (Swietenia macrophylla), two 5000 square meter clearings were established in each locations using each of three treatments: complete felling; slash and burn; machine-clearing with uprooted al...

In 2002, mahogany (Swietenia macrophylla) was listed on Appendix II of CITES (the Convention on International Trade in Endangered Species). This requires that all producing countries define and implement sustainable production systems for mahogany, the most commercially important neotropical timb...

Annual early fire, selective tree cutting and exclusion of grazing are currently used as management tools in the Sudanian savanna of Burkina Faso although their longterm effects on seedling recruitment are poorly documented. A factorial experiment involving fire, grazing and cutting, each with t...
