Abstract: Aiming at the different descriptions and even opposite definitions of transpiration parameters in different plant physiology textbooks, the transpiration ratio (TR), transpiration coefficient (TC), transpiration efficiency (TE), water requirement (WR), and water use efficiency (WUE) were analyzed and discussed by referring to the different plant physiology textbooks both at home and abroad. The concepts of TR, TC, TE, WR, and WUE were further amended and unified.

Key words: transpiration ratio, transpiration coefficient, transpiration efficiency, water requirement, water use efficiency
