Abstract
The study was made to examine the effects of artificial acid rain on needle chlorophyll contents
of Pinus densijlora and Pinus koraiensis seedlings.
Three-year-old seedlings of P. densijlora and P. koraiensis were transplanted into plastic pots
filling with mixed soil (perlite : vermiculite : sand 1 : 1 : 1 v/v) in early-October, 1983, and grown
in a vinyl-house at the Forestry nursery in Suweon. Seedlings were treated every three days with
20ml of artificial acid water containing pH values of 2.0 and 4.0 from Feburary 10 to March 24,
1984. As control, 20ml of tap water was also treated at the same time.
Needle chlorophyll contents of the two species decreased with increasing acidities. Needle chlorophyll
contents of the control plants did not change. The ratios of chlorophyll α to chlorophyll
β in both species decreased gradually with increasing acidities.
