| Title : | MORPHOLOGY AND ANATOMY OF INDIGENOUS RICE LANDRACES IN KHON KAEN, THAILAND |
| Abstract : | This study comprised collecting and determining the morphology and anatomy of leaf blade and leaf sheath of indigenous rice landraces in Khon Kaen, Thailand. A total of twenty-seven indigenous rice landraces were discovered, while, only 12- plant and grain samples were collected: Khao Plong Aew, Khao Jao Leuang, Khao San Pla Tong, Khao Gam Poon, Khao E-Leuang Noi, Khao Niaw dang, Khao Lao Taek, Khao E-Tom Kao, Khao Kam Pai, Khao Kao Gon, Khao Nang Nuan and Khao Mun Ped. Gross morphology was investigated and descriptions made. The anatomical characteristics of leaf blade and leaf sheath were studied using peeling and paraffin methods. The results demonstrated that the morphological and anatomical characters of 12 indigenous rice landraces are similar with a slight difference in some characters. Morphology differed in the color of collar, auricle and ligule as well as the shape and color of brown rice. The main distinguishing morphological characteristics for identifying indigenous rice landraces are grain features. For the anatomy of leaf blade and leaf sheath, the results revealed that there were only differences in the presence of prickles and the shape of anticlinal wall of epidermal cell on the lower surface of leaf sheath. Even thought, the anatomical characters of leaf blade and leaf sheath were not appropriated to identify the indigenous rice landraces in Khon Kaen. However, Khao Jao Leuang was distinguished from other indigenous rice landraces by the absence of prickles on both leaf blade surfaces. Moreover, Khao Jao Leuang is the only landrace in which the shape of the anticlinal wall of the epidermal cell on lower surface of leaf sheath, is undulate, others are sinuate. |
