Ac. Pereira et al., IN-VIVO AND IN-SITU MEASUREMENTS OF SPECTROSCOPIC AND PHOTOSYNTHETIC PROPERTIES OF UNDETACHED MAIZE LEAVES USING THE OPEN PHOTOACOUSTIC CELL TECHNIQUE, PLANT SCI, 96(1-2), 1994, pp. 203-209
A new and highly sensitive method, based on the photoacoustic effect,
is described for in vivo and in situ studies of photosynthetic activit
y of undetached leaves. The general utility of this simple phototherma
l method is demonstrated by examining the spectroscopy and photosynthe
tic activity of green, striped, and albino plants of maize (Zea mays L
.).
