摘要
We agree with Schnyder et al. （2009） that ＂Cell division rates cannot be estimated with the continuity equation if independent measurements of displacement velocity and cell length distribution are not available＂. To our knowledge, there is still a lack of information on the effect of salinity on the cell division rate in the division zone of grass leaves in published reports. Based on the study of the salt effect on the epidermal cell number in the mature wheat leaves （Hu and Schmidhalter 2007）, the results showed that, depending on the cell types, the total cell number in the abaxial epidermis was reduced by 16-23%. However,
