Named approach grafting because when grafting, rootstock as being picked up and jabbed by the top of each plant is still associated with rooting. The success rate of approach grafting is very high, but the process is quite difficult because the rootstock must be connected to the branch of the upper stem tree whose base is trunked. Therefore, approach grafting is only recommended for plants that are very difficult or can not be reproduced by grafting or okulasi.
We practice (in Vocational High School Bustanul Yatama, North Aceh), the success rate of this approach grafting is 80%. Of the 50 stems we tried, 40 stems we successfully made the seeds and we are ready to cultivate. The experiment we did was on a mango honey tree.
Type Approach Grafting
There are two types of Approach Grafting, namely the sitting and suspension suits.
In a sit-down, the root stem tree is placed in shelf made near the stem’s main tree. While on suspension, the root stem tree is hung on a pole fixed near the upper stem tree.
Steps Approach Grafting
Here are the steps to Approach Grafting.
1. Incision one side of the rootstock and the top trunk along 2-3 cm with a depth of 1/3 diameter of the stem until the wood tissue is visible. Keep the incision area in the upper stem and the rootstock has the same size and shape to facilitate the connection.
2. The shape of the incision is made rounded with a flat, smooth and clean surface so that when it is brought together, the two incisions of the incision are completely unified, no cavities between the two sticks are affixed. Thus the cambium of these two branches can be fused.
3. Attach the top and bottom stems, just in the incision area
4. Once fused, the field is tied together raffia rope or plastic tape by wrapped from bottom to top, then tied tightly. After that, the seedlings are watered regularly.
5. Two or three months after being punctured there will be swelling around the tied rod. This indicates the process of grafting is successful and the seeds can be separated from the parent tree.
6. Cut the seeds on the rootstock, 1 centimeter below the connection plane. Put the seeds under the shade or under the trees to protect from the sun.
Thus explanation of Approach Grafting Technique, we (in Vocational High School Bustanul Yatama, North Aceh) have successfully practiced Approach Grafting Technique on mango honey tree in accordance with the steps that have been described.
if you are interested in trying it, you should really do it according to the steps outlined above. Hopefully useful, good luck to try it
