| Summary: | 碩士 === 國立中興大學 === 森林學系所 === 100 === The research focused on the Phenology of Ficus pedunculosa Miq. var. mearnsii (Merr.) Corner at Cingwashih Trail and Jialeshuei in the Hengchun Peninsula. The goal of the investigation was to generate phenologic analysis of Ficus pedunculosa Miq. var. mearnsii (Merr.) Corner based on the different habitats, sexual differentiated in sexual populations phenology, syconium productive strategy, and the relationship of fig and leaf. The study ran from September 2009 to March 2012 at Cingwashih Trail and from May 2010 to March 2012 at Jialeshuei. The study indicated that, in both locations, there are significant seasonal differences in the phenology for each gender of F. pedunculosa Miq. var. mearnsii (Merr.) Corner, and the leaf phenology showed seasonal changes. According to Kendall’s rank correlation analysis, the mature leaves and the fig productions were correlated with temperature at Cingwashih Trail. However, the fig productions for each gender were correlated with temperature and only male trees were correlated with rainfall at Jialeshuei. The mature leaves and the fig productions have different correlated with temperature and rainfall in different habitats. During the observation period, the average corps female trees produced were less than male trees. According to Mann-Whitney test, crop production for each gender showed no sexual differentiation in two different habitats. However, female trees’ average fig/leaf ratio crops were less than male trees’ too. Fig/leaf ratio for each gender have obviously sexual differentiation.
Using the techniques of Inter-Simple Sequence Repeat (ISSR) fingerprints, we examined the genetic variation and relationship of F. pedunculosa Miq. var. mearnsii (Merr.). We collected 210 samples of F. pedunculosa Miq. var. mearnsii (Merr.) from 7 natural areas. Eight ISSR primers were used to proceed the reaction test of PCR and 8 primers were obtained. Population genetic (POPGENE) analysis revealed that total gene diversity (H) was 0.3028、0.2729、0.3196 for each gender and total population. Genetic index (Gst) was 0.2257、0.1894、0.1194 for each gender and total population, while gene flow index (Nm) was1.8437 for total population. The analysis of molecular variance (AMOVA) showed that the variance component among individuals within population were high. The results also indicated that the major variation existed among individuals within populations. The result of UPGMA cluster analysis showed that Hengchun Peninsula could be classified as a group; Lanyu, Green Inland and Eastern Taiwan’ population fell into a group. Since the Mantel test results showed that F. pedunculosa Miq. var. mearnsii (Merr.) populations geographic distance and genetic distance have no significant impact, this indicated the populations are randomly distributed. Therefore, the genetic drift group differentiation played a important role. To sum up, the F. pedunculosa Miq. var. mearnsii (Merr.) the major variation existed among individuals within populations.
Moreover, the results of the mantel test for the phenological distance matrix and genetic distance at Cingwashih Trail showed two were not related.
