Photosynthetic acclimation to growth-irradiance in two tree species of Magnoliaceae
|
Abstract:
Potential photosynthesis and photosynthetic acclimation in response to decreasing growth-irradiance were determined for two species in the family Magnoliaceae adapted to different light conditions, with Michelia meachurei being light-demanding while Parakmeria lotungensis shade-tolerant. Plants from both species were grown outdoors under three different light regimes, full light (natural daylight), 54% and 21% light respectively. Light-saturated photosynthetic rate of the leaves of M. meachurei was signifi...
