“…A 25 day old tomato seedling scion was the best compatible attributes regarding the fruit and tuber yield of pomato. The previous study has proved that a younger scion has a higher regenerating ability likely due to higher meristematic cell activity resulting in faster callus formation and quick healing of the graft union [22]. The highest success of a graft union is associated with intimate contact of the cambial regions both rootstock and scion [23].…”

The aim of this study was to evaluate the grafting compatibility of different varieties of tomato (Solanum lycopersicum L.) scions on potato (Solanum tuberosum L.) rootstocks to develop a ‘pomato’ plant. In this study three potato varieties; Diamant (P1), Cardinal (P2) and Asterix (P3), and two tomato varieties; Bangladesh Agricultural Research Institute (BARI) tomato-2 (T1) and BARI tomato-11 (T2) were used to make the grafted combinations T1P1, T1P2, T1P3, T2P1, T2P2 and T2P3, designated G1, G2, G3, G4, G5, and G6, respectively. Tomato seedlings aged 25 (S1) and 35 days (S2) were selected as scions. Graft compatibility was analyzed based on the growth and yield of the pomato plants. The results revealed that varieties and scion age had a significant effect on the pomato fruit and tuber yield. The initiation of flowering was not affected by the various graft combinations; however, plant height, leaf number, branch number, number of clusters per plant, number of fruit per cluster, number of fruit per plant, fruit length, fruit diameter, single fruit weight and total fruit yield per plant were higher in G5S1 among the combinations. On the other hand, the number of tubers per plant, single tuber weight, and tuber yield per plant were highest for a few combinations. Overall, it was concluded that Cardinal (P2) and Asterix (P3) potato were the most compatible for grafting with BARI tomato-11 (T2) at the scion age of 25 days (S1), based on vegetative growth and fruit and tuber yield of pomato plants.

“…Maximum success percentage i.e., 100% was obtained in mango by following cleft grafting technique in the month of June or March. On the other hand, Allan et al (2010) reported that in papaya side grafting brings about 80% success rate while Nguyen and Yen (2018) recommended cleft grafting using 1-month old rootstocks as the best method for maximum grafting success in papaya. Maximum graft success in plum i.e., 9.67 out of 10 grafts was achieved by following cleft grafting in April suggesting it to be the commercial method for grafting (Mozumder et al, 2017).…”

Mechanisms Underlying Graft Union Formation and Rootstock Scion Interaction in Horticultural Plants

et al. 2020

Grafting is a common practice for vegetative propagation and trait improvement in horticultural plants. A general prerequisite for successful grafting and long term survival of grafted plants is taxonomic proximity between the root stock and scion. For the success of a grafting operation, rootstock and scion should essentially be closely related. Interaction between the rootstock and scion involves complex physiological-biochemical and molecular mechanisms. Successful graft union formation involves a series of steps viz., lining up of vascular cambium, generation of a wound healing response, callus bridge formation, followed by vascular cambium formation and subsequent formation of the secondary xylem and phloem. For grafted trees compatibility between the rootstock/scion is the most essential factor for their better performance and longevity. Graft incompatibility occurs on account of a number of factors including of unfavorable physiological responses across the graft union, transmission of virus or phytoplasma and anatomical deformities of vascular tissue at the graft junction. In order to avoid the incompatibility problems, it is important to predict the same at an early stage. Phytohormones, especially auxins regulate key events in graft union formation between the rootstock and scion, while others function to facilitate the signaling pathways. Transport of macro as well as micro molecules across long distances results in phenotypic variation shown by grafted plants, therefore grafting can be used to determine the pattern and rate of recurrence of this transport. A better understanding of rootstock scion interactions, endogenous growth substances, soil or climatic factors needs to be studied, which would facilitate efficient selection and use of rootstocks in the future. Protein, hormones, mRNA and small RNA transport across the junction is currently emerging as an important mechanism which controls the stock/scion communication and simultaneously may play a crucial role in understanding the physiology of grafting more precisely. This review provides an understanding of the physiological, biochemical and molecular basis underlying grafting with special reference to horticultural plants.

“…This early recovery could also be due to the juvenility of the rootstocks and scions. Indeed, juvenile plants show a high meristematic activity responsible for the healing of the weld between the rootstock and scion [24]. Grafting resumption results physiologically in the fusion of the cambium of the graft and that of the rootstock.…”

Grafting is the most widespread vegetative propagation technique in cashew tree (Anacardium occidentale L.). Usually, cashew plant grafting are done on seedlings in plastic bags in nursery. In addition, to the low success rate, grafted plants have a low viability rate in field because main roots were broken during their transfer to the field. This study was carried out to evaluate the grafting success and survival rate of cashew seedlings planted in root trainer with different size (250 cc, 500 cc and 1000 cc). Each type of container was filled with two different growing substrates: coconut fiber and sawdust. Results showed that large size root trainers (1000 cc) have the highest percentage of graft success (96.67%). Rootstocks 45 days old presented the highest percentage of graft success in nursery (94.31%). The longest scions (12 cm) presented the minimum sprouting time (18.21 days). In the field, survival rate 100% of the grafted plants was recorded. In addition to the high survival rate ensured in field, root trainer is eco-friendly reusable and it light nature can prove a profitable technology for raising cashew elite plants regeneration.
