生态型地

The results showed that there were significant differences among fungal species or ecotypes in all above index,which varied with soil types.First,six fungi could colonize maize root on three soils,and the fungal colonization rate was higher on soil collected in the region that had been screened for cinnamon soil and brown soil.

结果表明，6种菌株在上述指标上存在显著的种间或生态型差异，土壤与菌株间存在显著的交互作用。6种菌株在3种土壤上都能与玉米形成菌根，在褐土和棕壤上大多数菌株在分离地所在地区土壤类型上的菌根侵染率较高，说明其对该土壤条件的适应性较强；在红壤强酸性土壤条件抑制了菌根真菌的侵染。

The results showed that liquorices in five different habitats differentiated into at least two ecotypes, which was significantly correlated with their habitats, MG liquorice and JG liquorice grew in habitats with higher aridity falling into one type and their young seedlings had high drought-tolerating capability, but DG liquorice and SG liquorice and NG liquorice belonged to the other type and their seedlings had lower drought tolerance than the former seedlings; of all climatic factors in liquorice habitats, water was probably the dominating factor affecting the differentiation of liquorice ecotypes.

同时，对种植在相同生境下的2年生子代植株的地上部形态特征进行了观测。结果表明，5种生境的甘草至少已分化为2种生态型，且与它们的生境有显著的相关性，生长在生境干燥度较大的民勤甘草和酒泉甘草为一类，其幼苗的耐旱能力较强，而生长在干燥度相对小的大兴甘草、沙坡头甘草以及内蒙甘草归为另一类，幼苗的耐旱能力也低于前者，甘草生境中气候因素的水因子可能是影响其生态型分化的主导因子。
