Richard P. Shefferson and Deborah A. Roach Longitudinal analysis in Plantago: strength of selection and reverse age analysis reveal age-indeterminate senescence Journal of Ecology 101
The hypothesis that plants escape senescence generally assumes that plants can continue to grow larger and increase reproduction as they get older. The results here show that size and reproduction decline with age and the rates of these declines toward death are lifespan- and age-dependent. Further research is needed to delineate the importance of age-determinate vs. age-indeterminate factors in senescence patterns across species.
