How rootstock/scion combinations affect watermelon fruit quality after harvest?

Area of Science:

• Horticultural Science
• Plant Breeding
• Agronomy

Background:

• Grafting is a horticultural technique used for over 50 years to improve vegetable crop resilience.
• It protects plants from soil-borne diseases, nematodes, abiotic stresses (temperature, salinity, drought), and soil pollutants.
• Watermelon is a prime candidate for grafting, with over 90% of global commercial plants being grafted.

Purpose of the Study:

• To review current knowledge on how rootstock/scion combinations affect watermelon fruit quality.
• To aid growers in selecting compatible combinations for improved fruit characteristics.
• To guide breeding programs in developing high-quality grafted watermelon varieties.

Main Methods:

• Literature review of scientific publications on watermelon grafting and fruit quality.
• Analysis of data concerning rootstock-scion interactions and their impact on fruit parameters.
• Synthesis of information on compatibility and incompatibility effects.

Main Results:

• Rootstock/scion combinations significantly influence watermelon fruit-quality parameters.
• Compatibility or incompatibility between rootstock and scion can enhance or impair fruit characteristics.
• Specific combinations have been identified that improve desirable fruit traits.

Conclusions:

• Understanding rootstock/scion dynamics is crucial for enhancing watermelon fruit quality.
• Informed grafting decisions can lead to cost-effective production of high-quality grafted watermelons.
• Further research into rootstock-scion interactions will optimize breeding strategies for superior fruit.
