우리나라의 경우 각종 장해와 주년 수요의 증가에 따른 불시재배의 증가로 인하여 저온신장성, 병해저항성 등과 같이 작물의 내성증진을 목적으로 접목묘의 이용이 급속도로 신장되고 있다. 특시 연작장해가 심한 박과형 채소류는 대부분 접목재배가 필요한 실정이다. 그러나 국내의 경우, 접목작업은 거의 수작업으로 행해지며 세밀한 조작과 숙련성 그리고 많은 노력을 필요로 한다. 따라서, 접목 생산성을 높일 수 있는 저가의 자동화 시스템 개발이 요구된다. 다양한 접목법들 중 현재 농가에서 가장 광범위하게 이용되고 있는 호접은 삽접 및 절단접에 비하여 자동화가 어렵고 활착 후 절단작업이 부가적으로 필요하나 접목 후 순화공정이 간단하고 활착률이 높다. 본 논문에서는 호접과 삽접에 대하여 접목 후의 활착률 및 접목에 소요되는 작업시간을 비교하였고, 호접법에 의거하여 작업공정을 생력화한 육묘 자동접목 시작기를 개발하였다. 시작기는 농가조합 및 중규모 육묘장의 설비를 지향하여, 묘판 및 접목묘의 취급을 제외하고 1인 접목작업 형태의 자동화 시스템으로 개발하였다. 시작기는 크게 버퍼기능을 부착한 배치형 육묘장치부, 2세트에 공압 매니퓰레이터, 대목과 접수의 원할한 접목을 위해 설계한 특수 그리퍼, 각고 조절형 절단부, 진동형 클립공급부 그리고 자동 클립 장착장치로 구성하였다. 접목 작업시간은 대략 4ch 정도이나 작업시간의 조정이 가능하도록 하였다. 실험실에서 수행한 간이접목 시험 결과, 절단날이 대목과 접수의 접촉부위를 관통할 때 접촉면이 서로 어긋나는 경우가 발생하였으나 육묘들이 호접에 적정한 기하학적 물성 요건을 갖춘다면 80% 이상의 접목 육묘의 기하학적 물성에 따른 체계적인 접목시험이 필요하다.

Manual grafting is a labor-intensive operation and highly susceptible to human error. Development of grafting robot has been considered as an effective alternative to manual grafting. The study was conducted to investigate the grafting efficiency between the domestically produced automated grafting robot and traditional manual grafting performed in a commercial plug seedling greenhouse. Plug seedlings of pepper (Capsicum annuum L.) 'Buchon' and 'Anseongmatchum' were sown as scions and rootstocks, respectively on March 29, 2013. The grafting was performed by a grafting robot, amateur grafters, and professional grafters on May 31, 2013. After grafting, the seedling efficiencies and seedling characteristics were compared in terms of plant height, the number of success as well as failure of seedling grafts produced in an hour. The results showed that plant heights were most uniform in the grafts performed by the professionals that had a 0.6 cm difference whereas an uneven difference of 2.1 cm difference was observed in plug seedling grafted by an amateur. However, plug seedlings grafted by the grafting robot were found to be uniform with 1 cm plant height difference. Moreover, the maximum number of grafting processed plug seedlings per hour (667 plants) was achieved by the grafting robot on compared with the seedlings grafted (466 plants) by the professionals. Furthermore, the least failure rate of 21.7% was noted upon the usage of grafting robot than the manual grafters. Thus, the results demonstrate that the technology of automated grafting robots is the most appealing and can be employed in commercial plug seedling greenhouses to overcome the drawbacks of manual grafting.

Self-and reciprocal-graftings were made between soybean varieties(cv.Hwangkeumkong, Paldalkong, Bokwangkong and Jangkyongkong) to assertain the relative role of shoot and root in soybean growth and yield determination. The influence of grafting per se on plant height and leaf number on main stem were negligible as evidenced by the insignificant differences between self-and reciprocal-graftings. The effect of grafting on flowering was different between different set of varieties grafted reciprocally. Self grafting delayed flowering 2 days and reciprocal grafting delayed another 2 days, in general. The effects of grafting on dry weights of different plant parts except pod were also insignificant. Reciprocal grafting increased pod dry weight in Hwangkeumkong and Paldalkong regardless whether they were used as scion or stock. Reciporcal grafting also influenced dry weights of Bokwangkong and Jangkyongkong significantly, but the response was different from those of Hwangkeumkong or Paldalkong. Jangkyongkong, when used as stock, decreased total dry weight of Bokwangkong significantly through the reduction of pod and stem dry weights. Stem diameter was increased by grafting, however, grafting decreased number of branches in all varieties. The average yields of self-and reciprocal-grafting were decreased by 11% and 24%, respectively, comparing to that of non-grafting, while average yield of reciprocal grafting was 14% lower than that of self grafting. Stem weight of grafted soybeans was decreased by 29-32% comparing to that of non-grafted soybeans, but the difference between self and reciprocal graftings was negligible. The genetic characteristics of scion was found to be more important than those of stock in determination of yield and stem weight. It was also indicated that varieties and characteristics are different in response to grafting.

The nutrient and irrigation management of scion and rootstock can alleviate stress on grafted transplants after grafting and promote the growth. This study investigated the effects of nutrient and irrigation management of scion and rootstock on the graft-take and growth of grafted pepper transplants. Before grafting, the scions were subjected to different water potential regimes in media by controlling the irrigation frequency and time. The scions were subirrigated 0, 1(two days before grafting), 1(one days before grafting) or 2 times for five days before grafting. The irrigation frequency and time influenced the water potential of media and the growth of scion and grafted transplants. At 13 days after grafting, fresh and dry weight of transplants which were irrigated once at two days before grafting were greater by 29 and 34% than those without irrigation during five days before grafting. This suggests that mild water stress on scion prior to grafting by controlling water management alleviate water stress on grafted transplants after grafting and improve the growth. Before grafting, the rootstocks were subjected to different nutrient regimes by controlling nutrient solution application. The rootstocks were supplied with nutrient solution 0, 1, 2, or 4 times. The nutrient application frequency and time influenced the electrical conductivity (EC) and pH of media. Accordingly, the growth and mineral contents of rootstock and grafted transplants were also affected. At 13 days after grafting, fresh and dry weight of transplants with four times of nutrient application increased by 30 and 20%, respectively, than those without nutrient solution supply during seven days before grafting. Therefore, it is recommended that nutrient solution be supplied more than four times during seven days before grafting for the production of high quality transplants.

Mulberry grafting season in normally a one month period starting at the end of March. Such a short period creates a shortage of qualified grafters and inflates wages. Pine tree sawdust was tested as a medium in which to preserve graftages. Sawdust was moistened to two ratios of water to dry weight of sawdust (1.5 and 2.0). Scions were either grafted the same day they were collected or first incubated for 10days at 15$^{\circ}C$. Grafting period could be extended to the middle of February under 1.5 times moisture content and fresh scions. Preservation of scions increased water content, T-N, P2O5, CaO and inositol, whereas decreased total C, glucose and fructose. With no preservation total C decreased, inositol increased slightly early March followed sharp decrease, and sucrose increased with time.

수박, 토마토 등에 널리 적용되는 삽접, 할접, 핀접 등의 접목 방법에서는 접수의 배축이 절단된 상태에서 접목이 이루어진다. 그러므로 상기의 접목 방법이 적용될 때 접수의 위조를 방지하고 접목묘의 활착율을 증대시키려면 접목 초기에 접목묘로부터 증발산이 과도하게 이루어지지 않도록 활착 환경이 조절되어야 한다. 인공광하에서 활착되는 접목묘로부터 증발산을 억제하면서 활착율을 높이려면 활착실 내에서의 상대습도가 90% 이상으로 높게 유지되어야 한다(Kim, 2000). (중략)

Grafting is an important skill for the stable supply and production of high quality. However, the shortage of skillful labor has become great difficulty for a mass production of grafting-seedling. In this study, a suitable mechanism for a grafting machine was developed. The following summarize the results of this study: 1. An insertion method was selected for mechanism of the grafting machine without bonding agent, clip, pin. This insertion-grafting method can be applicable to general vegetables and a mass production system. In addition to, this method is suitable for developing the grafting mechanism. 2. Growing point was removed while remaining both cotyledons on rootstock. The productivity of this system was five fold greater than the one of an experienced labor. 3. The rootstock processing was placed on left and scion processing unit was placed on right of the system, then processed rootstock and scion graft by rotating $180^{\circ}$. 4. The efficiency tests on mechanical grafting rate showed 98%.

수박 접목묘의 이용은 동일 지역에서의 연작 장해로 인한 만할병 방지 및 난방비 절약 등의 장점으로 점차 증가하고 있다. 이러한 장점에도 불구하고, 접목의 육묘 비용이 비싸고 접목 작업에 많은 노동력이 요구되기 때문에, 접목 자동화의 필요성은 증대될 것이다. 또한 효율적인 접목작업을 위해서 육묘 자체의 물성치에 근거한 접목 자동화 작업이 필요하다. 본 연구에서는 접목시 적용 가능한 수박묘 대목과 접수의 물성치를 분석하였다. (중략)
