对嫁接茄子与未嫁接茄子的光合特性进行了研究，结果表明：嫁接茄子的叶绿素含量显著高于未嫁接茄子，其光合速率（Pn）、胞间CO2浓度（Ci）、蒸腾速率（Tr）和气孔导度（Gs）的日变化规律与未嫁接茄子相同，嫁接处理降低了茄子的光补偿点和CO2补偿点，提高了茄子的光饱和点和CO2饱和点，从而提高了茄子的光利用效率和CO2利用效率，但嫁接处理的光补偿点和CO2补偿点均显著高于未嫁接处理。嫁接对不同砧木茄子光合特性的影响不同。
The photosynthetic characteristics of grafted and non-grafted eggplants were exhibited in the paper.The results showed that the chlorophyll contents of grafted eggplants were significantly higher than that of non-grafted one.The diurnal changing patterns of photosynthetic rate(Pn),intercelluar CO2 concentration(Ci),transpiration rate(Tr)and stomatal conductance(Gs)in grafted eggplants were the same as the non-grafted one,but their diurnal average values were significantly higher than that of the non-grafted one.At the same time,grafting decreased the light compensation and CO2 compensation points,and increased the light saturation and CO2 saturation points.Therefore,the efficiency of light and CO2 utilization of eggplants was also improved.However,effects of grafting on photosynthetic characteristics of eggplants differed in different root stocks.
