摘要
在河西走廊盐碱地,对12个葡萄砧木嫁接同一品种贵人香,通过测定叶片荧光与光合参数发现,盐碱与强光照交叉胁迫下SO4、圣乔治、420、Flourilush、1103P的Fo值最低,表明在盐碱地强光照条件下其反应中心受胁迫最轻;520A、5C、圣乔治、420、SO4 Fm较大,表明其PSⅡ电子传递效率高;SO4、420、圣乔治、5C、1103、3309CFv/Fm值较高,表明其发生光抑制或者PSII受到伤害轻;而5C、SO4、1103P、420、3309C的净光合速率较高。综合分析认为,SO4、420、1103P、5C砧木品种能较好适应当地高盐碱和强光照条件。
The varieties Riesling were grafted on 12 grape rootstocks grown in saline land of Hexi Corridor to explore the effect of rootstocks on photosynthesis of grafted grape.The chlorophyll fluorescence and photosynthetic parameters were measured.The results showed that the Fo value of SO4,St.George,420,Flourilush and 1103P was low under the stress conditions of alkali and strong light,which implied less stress to reaction center of photosynthesis;the Fm values of 520A,5C,St.George,420 and SO4 were high,which indicated that the electron transport efficiency of PS Ⅱ was high;the Fv/Fm values of SO4,420,St.George,5C,1103P and 3309C were high,so the photo-inhibition was weak;5C,SO4,1103P,420 and 3309C had higher net photosynthetic rate.In conclusion,SO4,420,1103P and 5C adapt to the local high salinity and high light conditions.
