Abstract

Abstract: Changes of chlorophyll a fluorescence parameters of cigar wrapper tobacco during maturing under the condition of shading were measured to analysis the characteristic of them.The results indicated that:the biggest efficiency of photochemistry and potential activity of PS Ⅱ were decreased; the changes of qP presented a bimodal curve; NPQ were decreased progressively with the aging of the blade; shut electron transmit speed and light quantum yield presented bimodal curve too.At the late stage of maturity,qP,shut electron transmit speed and light quantum yield were still high.

Key words: Cigar tobacco, Chlorophyll a fluorescence parameters, Shading
