Number of bands amplified using five MSAP selective primer combinations in the 11 materials used in this study.

*The names of primer combinations are abbreviations and their corresponding full name are listed in Table 1.**The band pattern that absent for Hpa II but present for Msp I was regarded as full-methylation and the numbers of this kind of band pattern amplified by each primer pairs were scored in each material.***The band pattern that for present Hpa II but absent for Msp I was regarded as hemi-methylation and the numbers of this kind of band pattern amplified by each primer pairs were scored in each material.

引物组合的名称采用缩写形式，其对应完整名称详见表1。
仅限制性内切酶Hpa II未扩增出条带、而Msp I可扩增出条带的条带类型，被判定为完全甲基化；针对每份试验材料，统计每对引物扩增得到的此类条带的数目。
仅限制性内切酶Hpa II可扩增出条带、而Msp I未扩增出条带的条带类型，被判定为半甲基化；针对每份试验材料，统计每对引物扩增得到的此类条带的数目。
