Abstract:
Taking 2-year-old ‘Chaoren’ kernel-used apricot as test materials，using pot experiments,under different conditions of soil moisture that normal supply (soil moisture was 75% field water holding capacity)，mild water stress (55%），moderate water stress (45%） and severe water stress (30%），photosynthetic pigment，photosynthesis，chlorophyll fluorescence parameters were research.The results showed that carotenoid content，chlorophyll a and b content，net photosynthetic rate (Pn)，transpiration rate (Tr)，water use efficiency (WUE)，maximum fluorescence yield (Fm)，the maximal photochemical efficiency (Fv/Fm) and PSⅡ potential activity were decreased under different soil water treatment.As water stress time increased they fell more faster；mild water stress drop was very small，moderate and severe water stress decreased.
