Leaf growth and senescence rates in brown-back wallaby grass
conference contribution

Leaf turnover begins with the appearance of successive leaves, which elongate until typically, a leaf ligule develops to indicate a mature fully expanded length. Green leaf life span extends from appearance to the beginning of senescence, which ultimately leads to death (Figure 1). Here, the individual rates of leaf growth and senescence for the Australian native brown-back wallaby grass, Rytidosperma duttonianum (Cashmore) Connor & Edgar, over the whole life cycle, are reported.
