茶多酚与儿茶素含量从高到低依次为汝城白毛茶、江华苦茶、城步峒茶、云台山种;各资源的游离氨基酸、茶氨酸和咖啡碱含量均为正常水平;汝城白毛茶属高茶多酚资源,其可可碱和茶叶碱含量较高。在阴凉条件下的净光合速率从高到低依次为汝城白毛茶、城步峒茶、江华苦茶、云台山种、净光合速率与光量子通量、叶面温度呈极显著正相关,与气孔阻力呈极显著负相关,相关系数分别为0.927 8、0.911 5和-0.893 7。在高温强光条件下,净光合速率从高到低依次为云台山种、城步峒茶、江华苦茶、汝城白毛茶,净光合速率与光量子通量、叶面温度和气孔阻力都呈极显著负相关,相关系数分别为-0.916 5、-0.932 8、-0.903...

Chemical composition,photosynthetic characteristics and productivity property of 4 Hunannative tea germplasm resources Camellia sinensis var.assamica cvs duntsa (A) and Jianghua (B).C.ptilophylla (C) and C.sinensis var.sinensis (D) were studied. The results showed that the contents of tea polyphenols and catechins in the leaves of C,B,A and D decreased successively,with C.ptilophylla being a polyphenolshigh resource because it contained more theobromine and theophylline than C.sinensis. The net photosynthetic rates of th...
