The Effects of Light Intensity on Leaf
Thickness
Leaf thickness was indicated
by specific leaf weight data. Light
intensity did not affect the thickness of the
leaves that were mature before the light
treatment was started, according to the
specific leaf weight data (Fig. 7). A
consistent result was also found from the
leaf anatomy study. No significant
difference between LL and HL leaf
structure could be detected during six
weeks of the light treatment (data not
shown). In contrast, the light intensity
effects on leaf thickness could be clearly
seen in the leaves that developed in the
different light conditions (Fig. 7). The
leaves developing to maturation in the LL
condition were thinner than the same-aged
leaves developing in the high light
condition, resulting in lower specific leaf
weight (Fig. 7). This was also supported
by the leaf anatomy results (Fig. 8).
