Abstract
This paper described photosynthetic light response curve of oil palm treated with elevated CO‚‚. The measurement was carried out by using LICOR 6400 on three tenera progenies of oil palm seedling namely Deli AVROS. Deli Yangambi and Deli URT. Increased CO‚‚ significantly affected light response curve properties of oil palm seedling. The apparent quantum yield a and Amax of oil palm seedlings were enhanced but dark respiration rate Rd was reduced. Seedlings exposed to CO‚‚ enrichment regardless of concentrations recorded significantly higher apparent quantum yield p0.01 of 43 more efficient in light harvesting compared to control whilst the Amax light saturation increased by 77 and 56 in the 800 and 1200 mol/mol CO‚‚ treatment respectively compared to the control. In contrast respiration rate was significantly reduced with increased CO‚‚ p0.01 by 64 and 54 at respective 800 and 1200 mol/mol CO‚‚ treatments over to control.
