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 'Sbuangjianyuhebao') 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 'Baitangyiug',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'.
