Effects of number of scion leaves on inlay grafting in three durian clones.

Abstract

In Malaysia, durian (Durio zibethinus Murr.) is traditionally grown from seed. As reported by FAMA (Federal Agricultural Marketing Authority), only about 3%of the durian grown in the state of Perak were budded I). Gradually, however, durian trees are vegetatively propagated, and the most common method presently practiced is bud-grafting. In recent years, many work and techniques have been done to offer growers propagation of durian2•3•6). Beside bud-grafting, cleft grafting is getting popular but there seems to be a tendency at the moment to use very juvenile rootstocks. With the exception of mangosteen and sapodiIIa, most fruits are using few weeks old Of course there are advantages in doing so, such as the ease of working, but there may be occassions where much older rootstocks need to be used. In the situation where the diameter of rootstock is much larger than that of the scion, grafting technique such as inlay grafting is suitable. Cleft grafting and bud-grafting are known to be good methods for young rootstock, but not for old rootstock. In the experiment, effects of inlay grafting for old rootstock was studied.
