| Summary: | Comparative leaf anatomy of sugarcane (Saccharum officinarum ‘KK3’) was investigated under early drought stress condition
between 30-90 days of planting. Forty anatomical characteristics were studied using a light microscope with significance
evaluated by numerical analysis. Results indicated that some anatomical features of sugarcane leaf responded to drought
stress. Almost all the anatomical characteristics of unstressed treatments showed higher values than stressed treatments. A
total of 21 out of the 40 characteristics showed a significant difference. Leaf thickness, stomatal size and interstomatal adaxial
epidermal cell size of treated plants decreased while cuticle thickness of adaxial lamina and stomatal density significantly
increased. This is the first report detailing leaf anatomy response to drought stress conditions in Thailand of sugarcane (S.
officinarum ‘KK3’). Results will provide useful basic knowledge for a better understanding of the adaptation mechanisms of
tolerant sugarcane genotypes under early drought stress conditions. |
