Species bearing recalcitrant seeds are generally confined to a large extent to the Tropical Belt of South East Asia, although, a number of species bearing such seeds have also been reported to occur in Temperate Forests. In the tropics, the ecosystems in which they strive are extremely diverse. In a natural stand these species are uneven in their age and are multilayered. They grow all year round under warm temperatures in the everwet moist conditions offered by the habitat in which they occur. With regards to the physiology and handling of such seeds, five important aspects need to be considered. These include the ecology/habitat in which the species occur, physiological state of the seed at the time of their harvest, germination physiology with regards to temperature, physiology effects of desiccation on such seeds and finally the physiological effect of storage on such seeds. This paper, therefore, sets out to discuss the present knowledge with regards to the ecology and physiology of such seeds and to identify the gaps in knowledge for research to better handle such seeds in the tropics.
