“…Poorly aligned graft components may result in complete failure of cambial union and failure to achieve vascular continuity in the union might result in desiccation of the scion and graft failure. The results are in line with [17,18]. Based on the above observations, it could be concluded that, among the three rootstocks used, S. sisymbrifolium rootstock was found to be a compatible one for tomato grafting.…”

A study was carried out at the Department of Vegetable Science, Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore, Tamil Nadu,India during 2019-2020 to assess the anatomical and histological changes within the graft union of tomato and identify compatible rootstocks for improved propagation of the crop. This experiment involved rootstocks of three wild tomatoes including Solanum torvum, S. sisymbrifolium and S. capsicoides and scions of two tomato hybrids including TNAU tomato hybrid CO3 and Shivam. The grafting was done using the cleft grafting method. The anatomical and histological sections of six graft combinations and two tomato scion samples were viewed microscopically at 7, 14 and 21 days after grafting (DAG). Among the six tomato graft combinations, S. torvum rootstock showed complete development of vascular connection at 21 DAG followed by S. sisymbrifolium rootstock, whereas S. capsicoides rootstock showed only callus growth at 14 DAG. Scion growth dominated the rootstock growth in S. torvum rootstock leading to mismatch of scion-rootstock stem thickness and delayed epinasty symptom at the later stages of plant growth. Of the rootstocks of the three species studied, S. sisymbrifolium rootstock was compatible for tomato grafting though it exhibited delayed vascular connection between the scion and rootstock.

“…1C). While this contradicts the hypothesis that relatedness determines success (Zlati et al 2011, Goldschmidt 2014, Melnyk and Meyerowitz 2015, Wang et al 2017, Melnyk 2017a), similar results have also been reported in a range of other interspecies grafts (Espen et al 2005, Pereira et al 2015).…”

“…Furthermore, graft success between species was found not to be the result of anatomical similarity at the graft junction. It has been reported that anatomical mismatching between scion and rootstock species is a cause of graft incompatibility (Zlati et al 2011, Dogra et al 2018). However, differing tissue and vascular arrangements were found in both successful and unsuccessful grafts, contradicting this concept (Table 1, Fig.…”

What drives interspecies graft union success? Exploring the role of phylogenetic relatedness and stem anatomy

The underlying mechanisms that determine whether two species can form a successful graft union (graft compatibility) remain obscure. Two prominent hypotheses are (1) the more closely related species are, the higher the graft success and (2) the vascular anatomy at the graft junction influences graft success. In this paper these two hypotheses are examined in a systematic way using graft combinations selected from a range of (a) phylogenetically close and more distant legume species, (b) species displaying different germination patterns and (c) scions and rootstocks possessing contrasting stem tissues and vascular patterns. Relatedness of species was not a good predictor of graft compatibility, as vascular reconnection can occur between distantly related species and can fail to occur in some more closely related species. Similarly, neither the stem tissues present at the graft junction nor the vascular anatomy correlated with the success of vascular reconnection. Relatedness and stem anatomy therefore do not appear to be the determining factors in successful vascular reconnection after grafting in legumes. These results are discussed in conjunction with other hypotheses such as the role of auxin.
