Xinxin2 in order to test the photosynthesis response to LFR in source leaves.
We studied the effects of leaf wetting on midday depression of photosynthesis regarding plant water balance and leaf morphological traits.
The plants without leaf wetting showed a significant reduction in midday photosynthesis with a concomitant decrease with leaf conductance, because of lower leaf water potential (-1.3 MPa) due to excessive transpiration water loss.
However, little is known about the leaf color mutants in tree peony.
The present study monitored the physiological and photosynthetic properties of a yellow leaf mutant (yl1) in tree peony.
