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。
