Evaluating Anatomical Characteristics Associated With Leaf Rolling in Northeastern Thai Rice Cultivars During Drought by Decision Tree

Leaf rolling is a common response to drought among members of the grass family. A detailed understanding structural changes that occur when rice leaves roll in may assist determining physiological mechanisms underlying this feature and its potential utility plant breeding. The anatomical characteristics cultivars native northeastern Thailand stress were evaluated study. Polyethylene glycol (PEG) treatments applied seedlings 28 two breeding for 10 d. When cultivated drought-prone environments, had leaf index between 4 7, which was classified as moderate high rolling. Rice anatomy exhibited profound drought, with smaller bulliform cells (36.8%), thicker epidermis (10.98%), vascular bundles (7.41%), bundle sheath (11.95%). Decision trees used explore association degree traits. According decision tree models generated on basis gain ratio, information gain, Gini index, epidermis, thickness, major factors root nodes, maximum accuracy 70.90%. Overall, indicated thin large cells, leaves, small are more likely display adaptations under conditions.
