有四种石花菜(Gelidium spp.)分布在智利中部的岩礁海岸。一般认为,质量最佳的琼脂,特别是用作微生物培养基的琼脂是用石花菜生产的。智利每年出口用于生产琼脂的三种石花菜达100吨(干重)。有关智利石花菜生态生理学和生产生态学的研究已经表明:舌状石花菜(G.lingula-tum)、智利石花菜(G.chilense)和未鉴定的石花菜(Gelidium sp.)的成体生长速度缓慢,再生能力也很低。这表明仅仅依靠野生种群来增加产量是困难的。虽然石花菜某些
There are four kinds of seaweed (Gelidium spp.) Distributed in central Chile’s rocky coast. It is generally accepted that the best quality agar, particularly agar for use as a culture medium for microorganisms, is produced from seaweed. Chile exports 100 tons (dry weight) of three sea buckthorn products for agar production each year. Studies on ecophysiology and production ecology in Lithospermum chilensis have shown that the adult growth rate of G. lingula-tum, G. chilense and unidentified Gelidium sp. Slow, regenerative capacity is also low. This shows that it is difficult to rely solely on wild populations to increase production. Although some of the stone cauliflower
