WebFeb 29, 2016 · Leaf senescence also includes downregulation and cessation of photosynthesis and eventually indicates the end of the growing season ( Wilson et al. 2001 ). The onset and duration of senescence is variable and triggered by cues such as temperature and photoperiod, as well as abiotic and biotic stress ( Keskitalo et al. 2005, Lim et al. 2007 ). WebFeb 2, 2024 · A leaf is often arbitrarily considered as a senescing leaf when the yellowing area is over 10% of the total leaf blade. This normally works fine when different genotypes or time points are compared. One problem with such scoring is that it is qualitative and cannot quantify the differences of yellowing areas. Furthermore, more accurate ...
