Study on compatibility and growth of grating between sweet potato (ipomoea fistulosa mart.ex.cholsy)

The aim of this thesis was to study the compatibility and the growth of the grafting between sweet potato (Ipomoea batatas (L.) Lam) with wild kangkung (Ipomea fistulosa Mart.Ex.Cholsy). This technique of grafting has been successfully used for plant propagation in many kind of plants but in one condition where the scions and rootstocks must be compatible each other. Both of the scions and rootstock must be in the same size and age. One of the most used methods of grafting is the cleft graft. The scions of wild kangkung were grafted onto the different rootstock of the five clones of sweet potato and were wrapped using the grafting tape and secured using plastics to protect the grafting part from damage. The data was collected for seven weeks. From the result obtained in this experiment, it showed that only clones of orange, purple and white fleshed have been survival and compatible in the grafting with wild kangkung with the percentage of 13%, 13% and 24% respectively. Based on the data analysis from this experiment, there were significantly different in the growth of the plants especially in the number of leaf, height of plant, width of leaf and perimeter of stem. These showed that the grafting actually had effects on the growth of grafted plants.
