The physiological responses of desert moss crusts under four artificial media (Beneck, Part, BG11, and Hogland) were investigated to evaluate the function of culture media during different culture periods. The results showed that the value of malondialdehyde (MDA) was at a maximum at 11d, on the contrary, chlorophyll-a, soluble protein, and soluble sugar were at a minimum. As the time increased, the value of MDA and soluble protein decreased faster in the Hogland, while the value of chlorophyll-a and soluble sugar increased. At the end of the culture period, the value of chlorophyll-a and soluble sugar was at a maximum in the Hogland, while the value of MDA and soluble protein was at a minimum. The results suggested that the Hogland medium had a promoting effect on the growth of desert moss crusts. The selected artificial cultivation medium towards wider and larger scale field applications of cultural desert biocrust was widely anticipated.

通过生理反应评估沙漠苔藓结皮的培养基

研究了沙漠苔藓结皮在四种人工培养基（Beneck、Part、BG11 和 Hogland）下的生理反应，以评估培养基在不同培养时期的功能。结果表明，丙二醛(MDA)在11d时达到最大值，相反，叶绿素-a、可溶性蛋白和可溶性糖含量最低。随着时间的增加，霍格兰MDA和可溶性蛋白的值下降得更快，而叶绿素-a和可溶性糖的值则增加。培养结束时，叶绿素a和可溶性糖在霍格兰的值最高，而MDA和可溶性蛋白的值最低。结果表明，Hogland培养基对沙漠苔藓结皮的生长有促进作用。
