Contribution of stem CO<inf>2</inf> fixation to whole-plant carbon balance in nonsucculent species
ReviewAbstract: In many plant species that remain leafless part of the year, CO2 fixation occurring in green stems rPalabras claves:carbon balance, CO reassimilation 2, green stem, stem net photosynthesis, stem photosynthesis, stem recycling photosynthesisAutores:Ávila-Lovera E., Herrera A., Wilmer TezaraFuentes:scopusEcophysiological and anatomic comparison of photosynthetic tissues of cercidium praecox (ruiz & pav. ex hook.) harms (fabaceae, caesalpinioideae)
