摘要： 为不同地区马铃薯优质高产栽培选择合适的品种，采用显微照相法和相对叶绿素含量测定仪SPAD-502plus，研究3个品种间马铃薯气孔密度和相对叶绿素含量。结果表明，马铃薯气孔密度随生育期而逐渐变大，在盛花期达到最大值后略有下降；马铃薯相对叶绿素含量（SPAD值）的变化趋势与马铃薯气孔密度基本一致；通过试验研究得出抗旱性高的品种为‘青薯168’，需氮量较高的为‘青薯2号’。

Abstract: For different areas potato high quality and high yield cultivation to choose appropriate variety, metallograph method and SPAD-502 plus were used to measure stomata density and relative content of chlorophyll in three varieties of potato. The research results showed that, potato stomata density gradually changed in growth period, and decreased in full-bloom stage; potato relative chlorophyll content (SPAD value) change trend were the same to potato stomatal density basically. Through the experimental study concluded that, drought resistance higher variety was ‘Qingshu 168’, nitrogen needed higher variety was ‘Qingshu 2’.
