차나무 재배시 문제해충 중의 하나인 노린재의 흡즙피해를 받은 차엽의 기능성분 변화를 알아보기 위하여 실험한 결과를 요약하면 다음과 같다. 1. 피해엽의 수분함량, 탄닌함량, 총질소 함량은 정상엽에 비하여 낮은 수준을 나타내었다. 2. 카페인 함량은 차이가 미미하였으며 카테킨 함량은 피해엽이 정상엽에 비하여 훨씬 낮아졌다. 특히 EGCG의 함량변화가 크게 나타났다. 3. 아미노산함량 또한 피해엽이 정상엽보다 낮았는데 프로린과 페닐알라닌 함량에서 큰 차이를 보였다. 4. 차나무 계통 W2-1은 피해엽에서 정상엽보다 더 높은 아미노산 함량을 나타내었다.

The true bugs are one of the problem insect decreasing tea quality by sucking to young leaves of tea plant. The purpose of this study was to understand the quality changes of tea leaves according to the sucking by true bugs. The damaged 8 accessions and the normal 8 accessions were selected on the tea germplasm garden and analyzed. Water content in damaged tea leaves showed lower than that of normal leaves. In case of average tannin content, it was observed slightly low in damaged leaves, whereas the normal leaves showed low tannin content among the same accessions. Total nitrogen, caffeine, and amino acid content, the important factors related to tea quality, showed highly in normal tea leaves compare to damaged tea leaves. It showed more difference between damaged and normal tea leaves in the same 3 accessions than that of among different 16 accessions. Therefore, it is important that we have to carefully control to insect in tea cultivation, because bugs sucking will be decrease tea quality. In addition, W2-1, accession name, showed high amino acid content in damaged tea leaves as 1,145 mg% compare to normal tea leaves with 973 mg%. It was considered that it is need to further study to understand the reason.
