Agronomic characteristics of tomato plant cultivar Santa Cruz Kada grafted on species of the genus Solanum

Abstract

In this study were evaluated gas exchanges, fruit production and fruit quality of tomato Santa Cruz Kada grafted onto different species of the genus Solanum, using two grafting methods. For the grafted tomato cultivation, the authors used a randomized complete block design, in a 8x2 factorial scheme, evaluating eight rootstocks: accessions of mini tomatos (0224-5, RVTC 57, RVTC 20 and 6889-50); wild tomato species Solanum habrochaites var. hirsutum (PI-127826); Solanum pennellii (LA716); Solanum sessiliflorum (cubiu); and tomato cultivar Santa Cruz Kada (self-grafting, control), and two grafting methods {cleft grafting (FC) and approach grafting (EC)}. The authors verified a significant interaction between rootstock x grafting method. The S. pennellii rootstock provided the best results for physico-chemical characteristics, when grafted using the cleft method. However, the same method, along with cubiu rootstock, presented lower fruit production. Considering the gas exchange and productive characteristics, S. habrochaites as rootstock for tomato Santa Cruz provided the best results for photosynthetic yield and water use efficiency, and for the commercial fruit production characteristic, both grafting methods, and for the average mass of commercial fruits when grafted using FC, with about 5.03 kg/plant and 163.5 g/fruit, respectively. In relation to the grafting methods, the cleft showed to be the most suitable.

Phenology growth and yield of grafted tomato plants in the high Andean region of Colombia

“…The increased performance with the use of rootstock vigor validates the findings of Kyriacou et al (2017); Soare et al (2018) and Zeist et al (2017), who indicated that grafting onto vigorous rootstocks has been employed in open fields and under protected cultivation, where grafting positively influenced growth, yield and fruit. Similar results were found by Khah et…”

Scion and Rootstock Differently Influence Growth, Yield and Quality Characteristics of Cherry Tomato

“…Accordingly, among the studied rootstocks, 'Dynafort' (S. lycopersicum × S. pimpinellifolium) proved to have the lowest plant and vegetative biomass and related σ 2 E values, meaning that its tendency to reduce tomato plant growth was poorly affected by the scion cultivar. S. habrochaites is a highly vigorous species, adapted to thrive in a wide latitudinal distribution, showing characteristics promoting growth in grafted tomato [22,23]. On the other hand, S. pimpinellifolium is the closest wide relative to the cultivated tomato, and has been used to improve tomato resistance to several biotic stressors [24] or fruit quality traits [25].…”

“…In the latter, the study of the turning point concerns, e.g. the relationship between the use of fertilizers and the productivity of soils or the increase of seed or bulb weight (Hongqiang et al, 2005), or the costs of inputs (Wang and Wan, 2012) or to characterize plant vegetation cycle (Zeist et al, 2017), But the casistic can be ample and diversified.…”
