Study on the Photosyrnthetic Characteristics of Tomato
In order to afford a theory for tomato planting in the dry area, the characteristics of photosynthesis in tomato leaf was studied. The results showed that the photosynthetic rate(Pn) of the different tomato varieties were different at 9:00 and 11:00 in flowering period,and Pn of Iigeer 87-5 was the highest.The diurnal variation of photosynthetic rate(Pn) in tomatoe leaf were in double-peak curves with decreasing feature at noun.The peak of peripheral leaf was recorded at 11 :00 and 17 :00.The bottom of peripheral leaf was recorded at 13:00.Stomatic conductance was the key factor of midday slump.
