경상남도 식물종의 생물계절성 연구

Abstract

This study’s purpose is to perform monitoring and analysis of Pinus densiflora Siebold & Zucc., Acer pseudosieboldianum (Pax) Kom., Rhododendron mucronulatum Turcz. var. mucronulatum, Rhododendron schlippenbachii Maxim., and Abies koreana Wilson growing in Gyeongnam Province for bioclimatological research, thereby establishing a long-term biogeographical forecast and management system, and to predict and manage changes in plants’ growth environment in advance, thereby producing measures for stable preservation of plant genetic resources. The result of monitoring the above plants showed that the blooming time of most of them tended to become later by 3 to 19 days in 2010 compared with in 2009. The time of their blossoms’falling also became later like their blooming time in most species except for Pinus densiflora Siebold & Zucc. in Jiri Mountain. All the species’ time of leaf unfolding in 2010 was similar to that in 2009 or became later by 4 to 67 days, which showed the most obvious disparity among the items of this phenological study. The time of their leaves’ turning red in 2010 was similar to that in 2009 or faster or later by a few weeks and the time of their leaves’ falling in 2010 was similar to that in 2009 in most species or became later by 1 to 2 weeks. Temperatures were not much different between in late 2009 and in late 2010 and as a result the times of their leaves’ turning red and falling became similar in the two periods. Some species’ irregular physiological cycles are considered to originate from differences in individual plants’ physiological and environmental characteristics.
