Grafted fruit vegetables have received more attention as growers and researchers found the positive impacts of significant yield increasing, diseases resistance, quality improvement, and more vigorous to overcome adverse conditions etc. These benefits have already had a significant impact in sustainable agriculture. Factors for a successful grafting depend highly on: 1) genetic characteristics, 2) vigorous, and 3) affinity of rootstock and scion; 4) grafting operational techniques; 5) environmental regulations during healing period; 6) incubation of grafted seedlings.
At present stage, tomatoes’ grafting techniques are popularly used in the Asian and pacific region countries. Ever since 1900, the Indonesia, Myanmar, Philippines, Taiwan, Thailand, and Vietnam learned the techniques through the Headquarter of world vegetable center (AVRDC) located in Taiwan. Now days, Vietnam has large-scale planting of bacterial wilt resistance grafted tomato. In Taiwan, 80% watermelon production was from grafted seedlings to deal with the sequential cropping induced disease and to increase their tolerance to high ambient temperatures and drought. To increase summer tomatoes’ production, Taiwan use wild eggplant rootstock to increase it resistance to flood and bacterial wilt.
Now days, grafted fruit vegetables still relied highly on men grafting. Grafting work requires appropriate training and accumulated experiences to manage. Due to the lack of manpower and the increasing demand of grafted seedlings, many countries start to development grafting operations mechanization and automation technology to alleviate the shortage of manpower needs of grafting. Take Netherland ISO Group company as an example, their 2013 developed tomatoes/eggplant grafting machine have already reached to the efficiency of 1000 seedlings/hour, which is 5.6 times efficient than manual operation of 180 seedlings/hour. Japan, Korea, and Taiwan also tried to develop automation grafting system, and now the mechanical to manual efficiencies are 1 to 4.4, 1 to 3.8, and 1 to 1 respectively.
This workshop is aim to 1) Collect and collate grafting technology and industrial development status of countries in the Asia-Pacific region; 2) Demonstrate Taiwan’s grafting technology and successful grafting industries; 3) Strengthen cooperative research and industrial development partnerships; and 4) Extend FFTC’s global impact by increasing database information
