Etiolated mutation is an essential branch of color variation in tea plant,it is crucial to research its photosynthetic physiological characteristics and change regulation of histos structure to reveal the mechanism of etiolated tea plant response environment.A tea cultivars (Camellia sinensis cv.Xiangfeicui) with some etiolated branches was discovered in a local tea plantation in Hunan Agricultural University,Changsha,China.We researched the chloroplast pigment content,ultrastructure,chlorophyll fluorescence parameters and anatomical structure of YPEL,YPNL and NPNL.The results showed that etio...
