การสำรวจชีพลักษณ์พืชที่มีศักยภาพเป็นพรรณไม้โครงสร้าง ณ ดอยกิ่วลม อำเภอปางมะผ้า จังหวัดแม่ฮ่องสอน

Abstract

The forest at Doi Kiew Lom, Pang Ma Pa District, Mae Hong Son province, was observed for phenological survey of plants as potential framework species during six months (from January 2012 to June 2012). Ten species of framework tree species, which were Afzelia xylocarpa, Bauhinia variegata, Erythrina stricta, Ficus auriculata, Ficus semicordata, Macaranga denticulata, Melia toosendan, Phyllanthus emblica, Prunus cerasoides and Syzygium cumini were selected. They were studied and the physical factors data were recorded including relative humidity, air temperature and rainfall for drawing phonological patterns and analyzing for correlation using Spearman’s rank correlation coefficient. The results showed that framework tree species were both positively correlated and negatively correlated with the physical factors. The air temperature significantly correlated to the highest number of phenological events, followed by rainfall and relative humidity, respectively. Afzelia xylocarpa showed the highest number of phenological events that were correlated with the physical factors. Production of Syzygium cumini flower bud (r= -0.821; p< .05) was correlated with the highest number of phonological events and showed negatively correlation with the air tempurature as well. After that, the results of this study were applied to construct the biology e-Learning courseware in the topic of forest resources and conservation for teaching high school 11th grade students. Results of the interview requestionnaire from the students indicated that E-book was greatly satisfied by the students.
