发菜(Nostoc flogelliforme)系一种陆生食用蓝藻,迄今不能人工栽培。实验室培养发菜获得初步成功,是最终解决该难题迈出的重要一步。水份是影响发菜生长的重要限制因子之一。直接原因是在水份条件好的情况下,由于微生物的大量繁殖,最终导致发菜个体解体而死亡。在基本了解并掌握有关发菜生态学特性和生物学特性的基础上,改进培养技术,就可使发菜在常规培养基上正常生长,培养14天,平均生长0.7—1厘米。 Nostoc flogelliforme is a terrestrial edible cyanobacterium that has so far not been cultivated artificially. The initial success of the laboratory cultivation of Chinese spinach is an important step toward finally solving this problem. Moisture is one of the important limiting factors that affect the growth of hairy vegetables. The direct reason is that in the case of good water conditions, due to the proliferation of microorganisms, eventually leading to the death of individual individuals disintegration. On the basis of understanding and mastering the ecological characteristics and biological characteristics of the hairy mustard, the improved cultivation technique can make the hairy root grow normally on the conventional culture medium for 14 days with an average growth of 0.7-1 cm.
