植物園의 野生植物 種子保全 戰略

Abstract

The need for conserving a broad range of genetic diveristy(seed) in botanic garden was emphasized. For effective conservation of genetic diversity, it is essential to build up banks of living seeds that are represented by their numbers and method of collection in the field throughout their distribution range. Storage methods were described, in which base(1ong term) and active(short term)methods were defined. The differences between seeds of orthodox and recalcitrant storage types were explained and testing and storage methods for dormancy type were suggested. General seed banking strategies in botanic gardens including a flow-chart of gene bank activities, problems of large quantities and size of seed and the need for duplicate collections were presented. Botanic gardens could be used very effectively for setting up wild plant seed banks with the aim of preserving rare or threatened plants, and of making available plant material for research and applied purpose. Creation of a seed bank in botanic garden is expected to be neither expensive nor difficult.
