When the first edition of this book was published in 1950, it predated the publication of the double-helical structure of DNA by three years.

The study of solute transport in plants dates back to the beginnings of experimental plant physiology, but has its origins in the much earlier interests of humankind in agriculture.

The Monograph deals with the conception, planning, implementation, results and conclusions of the International Witches' Broom Project (IWBP), which was set up in 1985 with the aim of producing an economic management system for witches' broom disease of cocoa.

Towards the Balance and Management of the Carbon Budget of the Biosphere The current state of misunderstanding of the global C cycle and our failure to resolve an issue that has been debated for 100 years (Jones and Henderson-Sellers, 1990) speaks loudly about the limitations of modem science when faced with the complexity of the biosphere.

Agroforestry reserach and development in Australia has been largely fragmented and many of the research results have never been published and are unknown.

Any scientific discipline needs a theoretical framework to guide its development and to sharpen the questions its researchers pursue.

This is the first detailed analysis of the complex and rich vegetation of the mountainous Korean peninsula, which ranges from arctic-alpine to subtropical in character, and in which more than 4500 vascular-plant species have been recorded, including many endemics.
