摘要

The transport of salicylic acid (SA) in heat-stressed Vitis vinifera plants was studied with C-14-salicylic acid. All leaves of young plants were cut off except the 4th, 5th, 6th, 7th, and 8th leaves. After the 6th leaves were fed with C-14-SA, the following treatments were conducted: (1) 4th, 6th, or 8th leaves were exposed to a high temperature of 38degreesC for 2, 6, and 12 h, respectively, while other parts of plants were kept at 27degreesC; (2) plants were kept at 27degreesC for 2, 6, and 12 h. The results showed that C-14-SA accumulated in the leaves stressed by heat. When the 6th leaves were at 38degreesC, less C-14-SA was exported from these leaves than from control leaves, but when the 4th or 8th leaves were kept at 38degreesC, more C-14-SA was exported. C-14-SA accumulation in the 4th or 8th leaves resulted from the 6th leaves directly and from the other parts of plants indirectly. These data suggested that SA was transported to a long distance and might be involved in the induction of heat tolerance.
