Table 1.
Analysis of variance for the effects of original growth irradiance level (I, at 3, 5, 13, 21, 29 and 50% of solar irradiance, with 100% irradiance also included for LMA) and transfer treatment (T, at three levels: PRE, CONT and TRANS) on Morpho-anatomical traits. Data were log transformed prior to analysis
