Forest tree improvement and seed technology are relatively neglected subjects as compared to forest management in general. Importance of forest improvement and seed technology has become important in recent years as forests have a significant role in maintaining climatic balance and conservation of biodiversity. The impending climate change may have a catastrophic effect on the ecological health of planet earth and may imperil the survival of life itself. This book is a modest effort in bringing out fundamental scientific information on forest tree improvement and forest seed science and technology in one compilation and therefore may prove useful to the researchers and students of forestry.
