注意植物迁地保护中的遗传风险Pay Attention to Genetic Risks in Plant Ex Situ Conservation
植物园 迁地保护 遗传风险 遗传管理
2008/1/6
摘要稀有濒危植物迁地保护的长期目标之一就是要保护物种的遗传多样性和进化潜力。介绍了稀有濒危植物在植物园迁地保护过程中存在的一系列遗传风险。由于引种或取样的不足，容易导致被保存的物种缺乏足够的遗传代表性；盲目的引种、不合理的定植以及材料的来源不清则会导致稀有濒危植物的遗传混杂、近交衰退或杂交衰退；人为选择和生长环境的改变也容易造成濒危物种对迁地保护的遗传适应。在实际的迁地保护工作中，这些遗传风险往往...
