利用图像分析方法研究了烟草植株在离体驯化过程中的气孔形态，转移后45 d叶面积增加了15倍，单叶气孔总数增加了4倍。在驯化过程中，叶片两侧气孔密度显著降低，但气孔长度和气孔面积（保护细胞和气孔）的增加弥补了气孔密度的增加。气孔伸长增加，表明离体驯化植株的气孔由原来的圆形气孔变为椭圆形气孔。
Image analysis was used in studying stomatal morphology during acclimatization of tobacco plantlets to ex vitro conditions, 45 d after transfer leaf area was 15 times, and total number of stomata per leaf four times increased. During acclimatization stomatal density was decreased considerably on both leaf sides, and was compensated by an increase in stomatal sizes, e.g., in stomatal length and in stomatal area (both guard cells and pore). Elongation of stomata was increased indicating that the originally circular stomata of in vitro plantlets were changed into elliptical ones in ex vitro acclimatized plants.
