SHOOT GROWTH FROM SCIONS TOP-GRAFTED ON DIFFERENT LITCHI CULTIVARS
Changing cultivars in established litchi (Litchi chinensis Sonn.) orchards is commonly carried out by top-grafting. However, there is little information about performances of different scion-rootstock combinations in grafted litchi trees. In this study, scions of different cultivars (Guiwei, Nuomici and Feizixiao) were top-grafted onto branches about 1 cm in thickness in trees of different cultivars (Baitangying, Baila, Feizixiao, Heiye and Shuangjianyuhebao) in the summer of 2006, and the length of shoots developed from the scions were measured 8 month later on June 7, 2007. The results showed that scions of Guiwei grew vigorously on Baitangying and Baila, but less vigorously on Heiye, while the growth was stunted when grafted onto Shuangjianyuhebao and Feizixiao. Nuomici scion grew most vigorously on Baitangying, less vigorously on Baila and least vigorously on Shuangjianyuhebao. Feizixiao shoot grew very well on Heiye. The results showed a poor compatibility between Guiwei and Feizixiao and that Shuangjianyuhebao might serve a dwarfing rootstock for Guiwei and Nuomici.
