The rootstock potential of Citron (Citrullus amarus) for watermelon

Abstract

Nowadays, global warming, abiotic and biotic stress factors pose significant challenges to the planet. Based on the increase in the population, the crop production of most agriculturally, economically, and nutritionally important crops as well as watermelon should be increased to their maximum. Grafting is a horticultural method by which the plant tissues are connected to enable the plants to continue growing together. It is usable technique to develop several horticultural traits in watermelon production such as yield and fruit quality and quantity. The main purpose of this study was to analyze the rootstock potential of citron (Citrullus amarus) genotypes for watermelon in terms of total yield, fruit characteristics and fruit quality (sugar and carotenoid contents). This study was conducted in the open field under low tunnel conditions within two successive years in Adana, Türkiye. The 11 Citrullus amarus genotypes (Kar 234, Kar 324, Kar 326, Kar 327, Kar 328, Kar 351, Kar 374, Kar 375, Kar 376, G 38, and G 40) were used as rootstocks and Crimson Tide F1 was scion. Commercial rootstocks: Maximus a Cucurbita hybrid rootstock (Cucurbita maxima × Cucurbita moschata) and Argentario (Lagenaria siceraria) were utilized for comparison, and non-grafted Crimson Tide was considered as a control group. According to the results, plants grafted onto C. amarus genotypes produced the highest total yield compared to the control group, but lower than to the plants grafted onto commercial rootstocks. All fruit measurement values of plants grafted onto commercial rootstocks resulted higher or similar than plants grafted onto C. amarus. It was determined that using C. amarus rootstocks positively affected fruit sugar content, however the amount of total lycopene and carotenoid content varied among genotypes. Kar 328, Kar 234 and Kar 351 were found to be promising genotypes as rootstock in terms of total soluble solids, total lycopene, total sugar, and total carotenoid contents respectively. In conclusion citron genotypes could be applied as an alternative rootstock for watermelon grafting program.
