From: Stomata variation in the process of polyploidization in Chinese chive (Allium tuberosum)
Stomal length and width of Chinese chive cultivars with different ploidy levels. a Stomatal length—measured in the longitudinal stoma axis; stomatal width—measured as the largest distance found between outer guard cell walls perpendicular to the longitudinal stomatal axis. b Boxplots of stomatal length to compare different ploidy levels of Chinese chive. c Boxplots of stomatal width to compare different ploidy levels of Chinese chive. d Comparison between length and width of GCs in the process of polyploidization
