ABSTRACT
Tea plants grown under sunshade net and greenhouse are new methods for coping with high- temperature stress in later summer in middle and south China. Aroma is one of the most important flavors and qualities of tea. In this research the cultivar “Longjing-changye” (LJCY) was grown under sunshade net, greenhouse and open field as treatments to study the changes of aromatic substances by using Head Space Solid Phase-microextraction and Gas Chromatography-Mass Spectrometry (HS-SPME/GC-MS). The results showed that tea plants grown under sunshade net and greenhouse had higher content of aroma substances in autumn tea. Those growing conditions are good for improving the contents of the ester and geraniol with floral and fruity fragrance in autumn tea. Moreover, overshadowing in summer is helpful to improve fragrance of fresh tea leaves quality in autumn tea, particularly the 50% sunshade net.
