“…A graft is composed of a root-bearing portion (the rootstock) and an aerial portion (the scion) provided by two plants [2]. Grafting is now performed worldwide and is of great economic importance [3][4][5][6]. Grafting has been revealed as a very useful technique in order to improve resistance to disease, insects and abiotic stress, to improve yields, to control plant size, to shorten the juvenile period, as a method of propagation, to induce unusual forms of growth, and to provide models for studies of plant physiology [1,2,7,8].…”

Despite the importance of grafting in horticultural crops such as tomato (Solanum lycopersicum L.), the structural changes that occur during the graft establishment are little understood. Using histological techniques, the present work examines the time course of changes on the anatomical structure of the graft junction in functional tomato homografts and compares it to that of heterografts and non-functional grafts. No apparent differences were detected between homo- and heterografts, showing similar tissue development. At 10 days after grafting, the cell walls of the scion and rootstock in the area of the graft junction were thicker than usual. Undifferentiated cells and new vascular tissue emerged from the pre-existing vasculature. Adventitious roots appeared mainly on the scion, arising from the pre-existing vasculature. At 20 days, more pronounced vascular tissue was visible, along with large areas showing vascular connection. At 210 days, vestiges of the changes undergone in graft development were still visible. Generally, non-functional grafts presented layers of necrotic remains and deposition of cell wall material in the cut edges, impeding the suitable scion-rootstock connection. Our results show that accurate changes in pre-existing vasculature and the cell walls of the adhesion line are crucial to the development of functional grafts.

“…At the working speeds of the TS3 and TS4 robots (210 and 240 grafts/hour, respectively), the number of grafts estimated for manual expert workers was already surpassed, i.e., a maximum of 150-240 grafts/hour [7,15], and an average of approximately no more than 1000 grafts per person per day [30,33,34]. In addition, the success rates for manual grafting are not usually very high, between 81% and 91% [35].…”

Conventional Industrial Robotics Applied to the Process of Tomato Grafting Using the Splicing Technique

et al. 2019

Horticultural grafting is routinely performed manually, demanding a high degree of concentration and requiring operators to withstand extreme humidity and temperature conditions. This article presents the results derived from adapting the splicing technique for tomato grafting, characterized by the coordinated work of two conventional anthropomorphic industrial robots with the support of low-cost passive auxiliary units for the transportation, handling, and conditioning of the seedlings. This work provides a new approach to improve the efficiency of tomato grafting. Six test rates were analyzed, which allowed the system to be evaluated across 900 grafted units, with gradual increases in the speed of robots work, operating from 80 grafts/hour to over 300 grafts/hour. The results obtained show that a higher number of grafts per hour than the number manually performed by skilled workers could be reached easily, with success rates of approximately 90% for working speeds around 210-240 grafts/hour.

Grafted veggie seedlings are an exceptional horticultural technique that has been used for a very long time. This approach, along with improved grafting techniques appropriate for commercial production and productivity of grafted vegetable seedlings, was introduced into Europe and other nations in the late 20th century. mainly connected to illness prevalence and abiotic stress tolerance, such as stress from soil and water pollution. Grafting is one of the best techniques to use in organic farming practises, according to a number of study studies on the subject. In order to increase a plant's quality and resilience to both high and low temperatures, grafting is used. The variety of rootstock used has a significant impact on the growth, yield, and fruit quality of scion solanaceous crops. With a focus on the genetics and breeding of the rootstock, this review examines recent literature on vegetable grafting and explores current problems affecting the grafting industry. Fruit quality of solanaceous agricultural plants grafted on S. sisymbriifolium, S. torvum, and S. toxicarium rootstocks—all of which are immune to soil-borne diseases—was compared to that of plants on their own roots.
