摘要(Abstract):
为了明确李果实花青苷合成的调控因子,以安哥诺李为试材,对果皮花青苷、内源激素和PAL、PPO活性的变化以及内源激素、酶活性与花青苷的相关性进行研究。结果表明,果皮花青苷含量在发育前期含量很低,发育后期含量迅速升高,呈上升趋势;果皮中ABA、乙烯、ZT含量和PPO活性与花青苷的变化趋势相同,乙烯释放量与花青苷呈极显著正相关关系r=0.8885**,ABA和ZT含量与花青苷呈显著正相关关系r=0.7159*和r=0.7476*,PPO活性未达显著水平;果皮中IAA、GA3含量和PAL活性变化在发育前期含量较高,在发育后期含量较低,果实发育过程中IAA、GA3含量呈逐渐下降趋势,与花青苷呈显著负相关关系r=-0.7039*和r=-0.8238*,PAL活性未达显著水平。
