Preliminary Evaluation of the Encapsulation Technology Used for Local Fruit Trees Germplasm Safeguarding

The encapsulation in a nutritive matrix is an effective technique which allows the conservation of vitro-derived explants and protects their viability. The encapsulated propagules are generated by submerging explants in a natural polysaccharide solution of sodium alginate and calcium chloride allowing to obtain uniform capsules. In this work, we present preliminary results of a study on the effect of an encapsulation protocol on any local fruit varieties, conserved in a Regional in vitro germplasm bank.

水质“风向标”

浮游藻类是水域生态系统中最重要的初级生产者,是水中溶解氧的主要供应者,对维持水环境的稳定起着极其重要的作用,同时对水域生态系统的功能性评价有着重要的指示作用。浮游藻类的种类组成、群落结构、丰度变化和空间格局,与水体的环境因子(如温度、光照、pH、矿物质等)之间关系密切。当水环境发生变化时,浮游藻类能够对水体状况的变化迅速作出响应。
