Two types of citrus declinio (CD) transmission trials approach root grafts were carried out: 1) Adult trees. In 1987, twenty pairs of 12-yr-old trees, one of each pair being diseased (donor) and the other of each pair being healthy (rceptor) were approach-root-grafted to each other. A year later most of receptor trees and many controls were showingsympoms of CD. Results showed that adult trees from affected orchards in S. Paulo State should notbe used as receptors for CD. 2) Three-yr-old plants(receptors) of six, planted in 1981 around diseased (donors) and healthy adult trees with five replications were approach-root-grafted.The three ungrafted plants remained as crontrols.In 1987 all young plants were dug out and each was replanted and used as root-graft donnors between two adult healthy trees (receptors) to test for retransmission of CD. In early 1988 the previously inocuted plants showed poor developmet; ten of eleven were dead in November when they were 7yr old. Control plants were normal. These results lead to the conclusion that declinio has been trasnmitted by approach root grafting. This is the first report of graft transmission of CD in Brazil. |
