Potted stock plants of Shorea leprosula (raised from stem cuttings) raised under a high irradiance range of 0-722 micro mol photons msuperscript 2 s-1 (nominally 30% of full sunlight) produced better height and diameter growth than those grown under a low irradiance range of 0-325 micro mol photons msuperscript 2 s-1 (nominally 10% of full sunlight). An enhanced net photosynthesis (Pn) may be the cause of the better growth rate in plants raised under high irradiance.
