"Considerable variation in the duration of serotiny exists among species of both Australian and South African Proteaceae. 'Weak' serotiny (pre-fire loss after
"Water loss from cones/fruits was poorly controlled, occurring in both light and dark. The rates of both H2O and CO2 loss from mature cones/fruits were negatively correlated with the degree of serotiny (r(2) = 0.59 and 0.18, respectively, P
The researchers concluded: "The correlation between the degree of serotiny and seed [P] indicates that stronger serotiny is required, much like sclerophylly, for survival under low nutrient availability in frequently burnt vegetation."
