The plant physiology manipulated by insect galls makes the differences in photosynthesis, insect defense mechanisms, phytochemicals, reactive oxygen species(ROS) contents, and the antioxidant abilities.

Part of the phytochemicals with antioxidant abilities reduce the damage of oxidant stress. In this thesis, there are five species galls used, including galls of Dryocosmus kuriphilus on Castanea mollissima, galls of Daphnephila taiwanensis on Machilus thunbergii, galls of Pauropsylla triozoptera on Ficus irisana Elmer, galls of Cecidomyiidae on Litsea acuminata (Bl.)

The thesis studies the meaning of the arrangements of phytochemicals based on whether there are concentration gradients in gall tissue. At last comparing the contributions of individual phytochemicals to antioxidative abilities by Grey Relational Analysis The chlorophyll contents in non-gall and galled leaves are different. However, the results can’t show direct evidences on the effects of photosynthesis efficiency and carbon assimilation. Phenolics and flavonoids play important roles in insect resistant and antioxidant activities. The contents of phenolics and flavonoids reduce outside-inside which reduce the damage to gall insects causing by insect resistance properties when gall insects eat the nutritive layer or uptake the plant fluids. Different contents of phytochemicals and ROS in gall tissue result in the different antioxidative abilities. The correlation between hytochemicals and antioxidative abilities are revealed by Grey Relational Analysis. Phenolics and flavonoids are antioxidants with high efficiencies. The results are consistent with previous researches. There are high contents of phenolics in Galla Chinensis. Galla Chinensis has high efficient antioxidative abilities. Advanced reaserch focusing on the antioxidative abilities of Galla Chinensis can be done. Extracting the components with antioxidative and healthy functions can promote the application value of Galla Chinensis. Wen-Dar Huang 黃文達 2015 學位論文 ; thesis 51 zh-TW |
