Quenching of chlorophyll fluorescence decreased and Non-photochemical Quenching of chlorophyll fluorescence increased for both alfalfas under drought stress. Generally speaking, qP decreased less and qN increased more in the high drought-resistance alfalfa than in the low drought-resistance alfalfa, suggesting that when under drought stress, the electron transport activity and photosynthetic apparatus was damaged less in the alfalfa with high drought-resistance than in the alfalfa with low drought- resistance.

PSⅡ光化学淬灭系数、非光化学淬灭系数的变化表现为干旱胁迫下两种紫花苜蓿qP值降低、qN值升高，总体上抗旱性强的紫花苜蓿qP降低的幅度低且qN升高幅度大，表明抗旱性强的紫花苜蓿PSⅡ反应中心电子传递活性受到的影响小，光合机构的损伤程度低。
