| Abstract: |
| Li-6400 was used to measure photosynthetic characteristic of Eggplant with plastic film covering and without covering in flatland and terrace in hilly and gully areas of the loess plateau. The results showed that(1)Diurnal variations of the net photosynthetic rate, transpiration rate, stomatal conductance of leaves of eggplant between flatland and terrace changed as double-peak curve in a day. It was speculated that the midday depression of eggplant in flatland was mainly caused by the stomatal factor and non-stomatal factor was one of the most important factors causing the midday depression of the eggplant in terrace. (2)The daily mean value of the photosynthetic rate, transpiration rate, stomatal conductance, intercellular CO2 concentration of the eggplant in terrace was significantly higher than in flatland(P<0.01), while the daily mean value of the leaf water use efficiency was significantly lower than in flatland(P<0.01). (3)There was no significant
difference between eggplant with plastic film covering and without covering both either in flatland or terrace(P>0.05). |
