Abstract

Comparative study on photosynthetic characteristics and fluorescent characteristics among introduced tea varieties.

Abstract

Using portable photosynthetic meter and luminoscope, we measured photosynthetic and fluorescence parameter of eight introduced tea cultivars. The eight tea cultivars were Pingyangtezao, Wuniuzao, Longjingchangye, Longjing 43, Baihaozao, Bixiangzao, Anjibao, Qilan in Tongbai county. The results showed that chlorophyll a, chlorophyll b and total chlorophyll content of Pingyangtezao were the highest among 8 introduced varieties, thus it will be suitable for making high quality green tea. Baihaozao and Qilan had higher potentialities of photosynthesis, such, as Pn, Fv/Fm, Fv/Fo, ΦPS II and ETR. Longjing 43 had higher drought resistance, but Pingyangtezao had the lowest drought resistance. This research provided the scientific proofs for introducing tea and cultivating plant in Tongbai area.
