e2“Grafting tomato ‘Kommeet’ onto LA 1777 increased shoot growth at intermediate and optimal T and root growth at low or intermediate T in comparison with self-grafting or grafting onto ‘Moneymaker’”
e1“Tomato ( Solanum lycopersicum cv. Kommeet) plants were either self-grafted, grafted onto the cold-sensitive cultivar Moneymaker or onto LA 1777, a cold-tolerant accession of Solanum habrochaites”

- Intervention effect Grafting Kommeet tomato onto LA 1777 increased root growth at low or intermediate temperature compared with self-grafting or grafting onto Moneymaker.
- Intervention effect Reducing temperature significantly suppressed tomato fruit yield through fewer fruit per plant, regardless of grafting.
- Intervention effect Grafting Kommeet onto LA 1777 restricted fresh and dry fruit mass compared with self-grafting Kommeet, as a result of fewer fruits per plant.
- Intervention effect Grafting Kommeet onto LA 1777 did not influence flower number per plant or mean fruit mass compared with self-grafting.
- Intervention effect LA 1777 rootstock had a negative effect on fruit setting in tomato.
- Mechanism The negative effect on fruit setting points to impaired pollen fertility, with signals originating from the root.
- Intervention effect At low and intermediate temperature, LA 1777 grafts raised soluble carbohydrates, total amino acids and guaiacol peroxidase activity in roots to higher levels than S. lycopersicum rootstocks.
- Intervention effect At low and intermediate temperature, LA 1777 grafts maintained significantly lower malondialdehyde content than S. lycopersicum rootstocks.
- Intervention effect Grafting onto S. habrochaitis points to much weaker oxidative stress in roots than grafting onto S. lycopersicum rootstocks at low and intermediate temperature.
- Intervention effect At low and intermediate temperature, LA 1777 grafts had significantly higher soluble carbohydrates, total amino acids and guaiacol peroxidase activity in leaves and fruit.
- Intervention effect At low and intermediate temperature, LA 1777 grafts had significantly higher superoxide dismutase in fruit.
- Intervention effect LA 1777 improved the level of antioxidant compounds in tomato shoots, enhancing adaptation to temperatures lower than optimal.
