Physioecology Of Fig Leaves And Fruits In Conosycea And It's Influence Upon The Mutualism System Between Ficus And Fig Wasps

The mechanism of ecological factors affect on the adaptive evolution is becoming a new direction of Physioecology. Leaf and fruit are the organs that very sensitive to environmental change, and they also have some close correlations. In order to investigate the Physioecology effects on the fig-wasp mutualism, we choose 9 species of figs in Conosycea and did some research on the SPAD, leaf area, fig size, water content, wasp's lifetime, flower and wasp number, The results are as follows.1. The SPAD and leaf area are signifcant different among 9 species, also among 3 sample trees in one specie under different light condition. There is signifcant linear correlation between leaf area and seeds, galls, female flowers and total flowers but no correlation with male flowers. There is none correlation between SPAD and any flower inside the fig.2. There are signifcant linear correlation among fig size, water content, and foundress number in B-phase. (R2= 0.9619, R2= 0.9533, R2= 0.8772, p< 0.01)3. In natural condition, there are signifcant linear correlation among fig water content, seed size, non-pollinators, gall flower abortion but no correlation among pollinators and seed numbers. Mabye the reason is we didn't control the foundress number, so there exist some competition. 4. In Ficus altissima, Ficus curtipes, Ficus glaberrima and Ficus stricta, control experiment indicate that pollinator and oviposition rate have a degressive trend along with the water content decline. While the seed number and pollination rate have no signifcant trend.5. Eupristina sp. and Diaziella yangi have similar searching and entering behaviors. There are signifcant difference in the searching time but not in the entering time. Inside the fig, oviposition and pollination period of Eupristina sp. and D. yangi were similar, which it was at most three days. Eupristina sp. and D. yangi showed some similar biological traits in the female floral phase, which is possibly resulted form long-term coevolution between the two wasps and Ficus host.
