植株干重、总叶面积和总匍匐茎长度具有显著的基株间差异。
Additionally, genotypic (genet) variation of plant dry weight, total leaf area and total stolon length in the experimental plants was found.
结果表明，以垄栽覆盖地膜方式马铃薯的出苗率最高，成熟期最早，植株最高，分枝数最多；但茎粗、叶面积指数、匍匐茎长、产量和单株生物学产量则以浅旋耕覆盖稻草方式最高；
The results showed that, for all treatment, the seedling emergence rate and the stem length of ridge cultivation model was the highest and its mature date was the earliest.
