Reduce leaf age with plant age #29

Closed lpmorenoc closed 4 years ago

lpmorenoc commented 4 years ago

Based on the data from Lian & Cock (1979) there is some reduction of the leaf duration with the age of the plant including in leaves that are not shaded.

Data from Irikura does not show the same trend with some increase on the leaf duration under low temperatures. However, Lahai et al. 1999 showed a reduction in the leaf duration for 3 varieties in 2 environments: Connor & Cock (1981) also show a reduction on leaf life:

Maybe the best option is to define a possible reduction in the leaf life as a cultivar coefficient.
