低农药残留量的乌龙茶种质资源筛选研究

以福建省武夷山茶叶科学研究所鸟龙茶种质资源圃120份资源为试验材料，依外部形态特征初步筛选出31份比较有希望的品种（系）。将联苯菊酯、甲氰菊酯、氯氰菊酯和噻嗪酮4种农药喷施于这31份资源，7d后采摘鲜叶，烘干固样。用气相色谱法分析检测31份品种（系）鲜叶中4种农药的残留量，筛选出低联苯菊酯、低甲氰菊酯、低氯氰菊酯和低噻嗪酮残留量的乌龙茶特异资源各5、4、3和7份。

A Study on Screening Germplasm Resources of Oolong Tea Plant with Low Pesticide Residue Content

In order to screen germplasm resources of oolong tea plant(Camellia sinensis(L.)O.Kuntze) with low pesticide residue contents,we used 120 tea plant resources in the Oolong Tea Variety Garden of Fujian Wuyishan Tea Research Institute as materials.According to the appearance of tea plant,31 tea plant resources had firstly been screened as candidate.Four pesticides,bifenthrin,fenpropathrin,cypermethrin and buprofezin were sprayed on the 31 cultivars or lines.The tea new shoots were plucked 7d later and their pesticide residue contents were mensurated and analyzed by gas chromatography.The cultivars or lines with low pesticide residue content had been screened 5,4,3 and 7 germplasm resources with low residue contents of bifenthrin,fenpropathrin,cypermethrin and buprofezin,respectively.
