assessment of N content of the tea plant is necessary for N fertilization. Traditional methods for chlorophyll and N determination include soil testing, plant tissue analysis, and long-term field trials. Although these methods are accurate, they are

great benefit to macadamia growers. Chlorophyll and other components related to chlorophyll account for ≈75% of leaf N ( Loomis, 1997 ), making chlorophyll a fairly accurate indicator for N status in leaves. The SPAD-502 Chlorophyll Meter (Konica Minolta

excitation pressure may occur as a consequence of a reduction in PSII antenna size ( Huner et al., 1998 ). These mechanisms avoid damage to photosystems but result in a decrease in photosynthesis ( D'Ambrosio et al., 2006 ). Hence, chlorophyll fluorescence is
