Abstract:
In order to understand influence of 5-aminolevulinic acid (ALA) on photosynthetic gas exchange，chlorophyll content and growth indexes in grape leaves under salt stress (NaCl)，two varieties of grapes ‘Summer Black’ (salt 〖JP4〗sensitive) and ‘Rizamat’ (strong salt resistance) were used as test materials，with three salt stress level of 0，2，4 g?kg-1 and different foliar spray of 0，75，150 mg?L-1 concentration of ALA on two grape varieties of ‘Black Summer’ and ‘Rizamat’，photosynthetic gas exchange，chlorophyll content and growth index were measured.The results showed that，the 2 g?kg-1 salt stress and 75 mg?L-1 ALA，4 g?kg-1 salt stress and 150 mg?L-1 ALA treatment respectively for the ‘Summer Black’ and ‘Rizamat’ grape，the Pn，E，Gs and the increasing of Ci showed most significantly，the content of chlorophyll content increased greatly and the two leaf photosynthetic gas exchange showed decreasing of grape plant height，stem diameter relative growth showed the most obvious effect to ease.Therefore，the relief effect of concentration of 150 mg?L-1 ALA on ‘Rizamat’ grape was relative better to the concentration of 75 mg?L-1，concentration of 75 mg?L-1 ALA on ‘Summer Black’ grapes was relative better to the concentration of 150 mg?L-1.
