Abstract

By feeding carbon 14 to one year Chinese fir and collecting root exudates periodly, the results showed that 1.06%, 4.90% and 24.04% of the photosynthates were transported to the root 24, 72 and 480 hours after feeding respectively. The root exudate with carbon 14 were detected as soon as the labeling was finished. The summit of exudating occured 72~120 hours after feeding, afterwards, reducing with time. By separating and determining, the exudates contained 39.52 of carbohydrates, 13.80% of organic acid and 5.45% of amino acid.
