Abstract: This is the first reporton energy all ocation pattern sin the bryophytes.Duirng the life cycle of Dolicho mitri opsisdiversi form is,energy value in different plan torgans followed the order:Perichaetium(9305.1J/g)>Sporophyte(9196.1J/g)>Gametophyte(from 4075.6 to 6558.6J/g).Energy alloca-tion to game to phyte accounted for the most proportion,while the eneryg allocation to mature sporophy tewas only3.2%.The energy allocation followed the order:Gametophyte>Sporophyte>Aperi chae tium.There sult sshowed:energy all ocation to there productive organ (perichaetium orsporophyte)was lowwhi lewith highenergy value sand the reproductive process of Dolichomitriopsis diversi form isneeded a lot of eneryg.
