以15年生油荼‘湘林XCL15’为试材,利用LI-6400XT便携式光合作用测定系统和~(13)C示踪技术,研究了不同库源关系对油茶光合作用、~(13)C光合产物分配和果实品质的影响。结果表明,库源比升高显著提高油茶叶片光合效率,其中二叶一果处理的叶片SPAD值较四叶一果和六叶一果分别提高了4.30%和4.89%,净光合速率提高了3.58%和6.45%,最大光化学效率提高了2.71%和8.00%,实际光量子产量提高了13.26%和36.20%,光合电子传递速率提高了17.69%和41.68%。六叶一果处理比四叶一果和二叶一果的果实~(13)C总量分别提高了76.74%和200.78%,单果重较后两者分别提高了60.51%和65.95%;距离标记叶最近的第一果13C总量较第...

The photosynthetic parameters, chlorophyll fluorescence kinetics, distribution and utilization of 13C and quality of fruits were investigated by LI-6400XT and isotopic tracing under different sink-source relationships, using 15-years Camellia oleifera 'XianglinXCL15' as materials. The results showed that photosynthetic efficiency was significantly increased after source-sink ratio decreased. SPAD, Pn, Fv/Fm, ΦPSII and ETR under treatment of 1 fruit-2 leaves were raised by 4.30% and 4.89%, 3.58% and 6.45%, 2.71% and 8.0%, 13.26% and 36.20%, 17....
