摘要
对平阳特早、乌牛早、龙井长叶、龙井43、白毫早、碧香早、安吉白、祁兰8个引进品种的4 a生无性系茶树的光合特性、荧光特性进行了比较研究,旨在为河南茶区筛选出优良的茶树栽培品种。结果表明,平阳特早的叶绿素a、叶绿素b、总叶绿素含量明显高于其他品种,适合制作名优绿茶;碧香早、祁兰净具有最高的净光合速率(Pn),PSⅡ最大光化学效率(Fv/Fm)、PSⅡ电子传递速率(Fv/Fo)、PSⅡ实际光化学效率(ΦPSⅡ)、表现电子传递速率(ETR);龙井43最耐旱,平阳特早耐旱性最差。
Using portable photosynthetic meter and luminoscope,we measured photosynthetic and fluorescence parameter of eight introduced tea cultivars.The eight tea cultivars were Pingyangte-zao, 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、ΦPSⅡ 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.
