• It grows taller and thus produces a longer trunk, which is more valuable as timber.<br />
• Seed propagation is practiced in most jackfruit growing countries.<br />
The disadvantages of this method are:<br />
• The characteristics of fruits produced by <strong>the</strong> seedling trees cannot be guaranteed, and<br />
are not necessarily <strong>the</strong> same as those of <strong>the</strong> mo<strong>the</strong>r tree.<br />
• The time taken by seedling trees to reach fruit-bearing age is usually longer than <strong>for</strong><br />
those trees propagated by vegetative methods.<br />
• The trees grow taller than those propagated by vegetative methods, which is a<br />
constraint in management and harvesting.<br />
4.2.2 Vegetative propagation<br />
• Vegetative propagation can be carried out by different methods. Veneer and epicotyl<br />
grafting are commonly practised in jackfruit in Asia (Haq, 2006). Details are<br />
described in Section 5.<br />
• Fruiting and fruit quality of vegetatively propagated trees are <strong>the</strong> same as those of<br />
<strong>the</strong> mo<strong>the</strong>r tree.<br />
• Vegetative propagation is particularly favoured in Thailand.<br />
The advantages of this method are:<br />
• The fruit quality of <strong>the</strong> new tree is assured; it will be <strong>the</strong> same as <strong>the</strong> mo<strong>the</strong>r tree.<br />
• The tree reaches fruit-bearing age sooner than in seed-propagated trees.<br />
• The trees remain relatively shorter in stature, which makes management and<br />
harvesting easier.<br />
The disadvantages of this method are:<br />
• The trees are often shallow rooted.<br />
• Trees tend to be dwarf and to produce branches at a low level, which results in<br />
lower quality timber with a shorter trunk.<br />
