| 内容記述 | The translocation of photoassimilate from intact tomato plant lateral shoot leaves and their rate of contribution to the soluble solid content of tomato fruit were investigated using 11CO2 and a positron-emitting tracer imaging system (PETIS). After 11CO2 application to the 4th leaf of the lateral shoots or to the leaf just below the fruit truss in the main shoots, 11C translocation to the fruits began after about 40 min and 1 hour, respectively. The rate of contribution of lateral shoot leaves to the translocation of photoassimilate to the fruits was revealed by the amount of 11C translocated from the 7th, 8th and 10-12th leaves of the main shoots and the 1st-4th leaves of the lateral shoots to the fruits. The rate of contribution of the 1st-4th leaves of the lateral shoots to photoassimilate translocation to the fruit was 44.6-80.1%. The photosynthetic rate of the 4th leaf of the lateral shoots was higher than that of the leaf just below the fruit truss. These results show that the lateral shoot leaves contribute significantly to the translocation of photoassimilate to thefruits, and that leaving the lateral shoots may have an influence on the raise of the tomato fruit soluble solids content. | |||||
