“…Grafting is used widely with tomato and watermelon to improve water and mineral nutrition of plants, enhance the tolerance to soil-borne diseases (e.g., fusarium wilt) and abiotic stress, as well as to increase yield and fruit quality (Kyriacou et al, 2017). Complex interactions between rootstock type, growing season, salinity, and genotype on carotenoid concentration, particularly lycopene, have been reported in both vegetable crops, leading to conflicting results (Fekete et al, 2015; Marsic et al, 2018).…”

The quali-quantitative evaluation and the improvement of the levels of plant bioactive secondary metabolites are increasingly gaining consideration by growers, breeders and processors, particularly in those fruits and vegetables that, due to their supposed health promoting properties, are considered “functional.” Worldwide, tomato and watermelon are among the main grown and consumed crops and represent important sources not only of dietary lycopene but also of other health beneficial bioactives. Tomato and watermelon synthesize and store lycopene as their major ripe fruit carotenoid responsible of their typical red color at full maturity. It is also the precursor of some characteristic aroma volatiles in both fruits playing, thus, an important visual and olfactory impact in consumer choice. While sharing the same main pigment, tomato and watermelon fruits show substantial biochemical and physiological differences during ripening. Tomato is climacteric while watermelon is non-climacteric; unripe tomato fruit is green, mainly contributed by chlorophylls and xanthophylls, while young watermelon fruit mesocarp is white and contains only traces of carotenoids. Various studies comparatively evaluated in vivo pigment development in ripening tomato and watermelon fruits. However, in most cases, other classes of compounds have not been considered. We believe this knowledge is fundamental for targeted breeding aimed at improving the functional quality of elite cultivars. Hence, in this paper, we critically review the recent understanding underlying the biosynthesis, accumulation and regulation of different bioactive compounds (carotenoids, phenolics, aroma volatiles, and vitamin C) during tomato and watermelon fruit ripening. We also highlight some concerns about possible harmful effects of excessive uptake of bioactive compound on human health. We found that a complex interweaving of anabolic, catabolic and recycling reactions, finely regulated at multiple levels and with temporal and spatial precision, ensures a certain homeostasis in the concentrations of carotenoids, phenolics, aroma volatiles and Vitamin C within the fruit tissues. Nevertheless, several exogenous factors including light and temperature conditions, pathogen attack, as well as pre- and post-harvest manipulations can drive their amounts far away from homeostasis. These adaptive responses allow crops to better cope with abiotic and biotic stresses but may severely affect the supposed functional quality of fruits.

“…Our study is compatible with the results of Petropoulos et al (2014) reporting that fruit flesh color mostly depended on the rootstock-scion combination. Fekete et al (2015) informed us that L* value varied from 35.17 to 42.71; C* value 31.59 to 38.41; h angle 33.42 to 36.13, and that while interspecific grafting decreased h angle value, it increased C* value.…”

“…Bruton et al (2009) reported that lycopene content for watermelons ranged from 43.6 to 78.9 µg/g. Fekete et al (2015) reported that interspecific hybrid rootstocks (C. maxima x C. moschata) increased the lycopene contents of watermelons. Contrary to the above-mentioned researcher, Turhan et al (2012) didn't observe any differences in watermelon lycopene content for grafted and ungrafted plants.…”

In this study the effects of rootstocks on watermelon fruit quality and yield were investigated by comparing grafted plants with non-grafted and self-grafted ones in open field conditions in over two consecutive years (2013-2014). The watermelon cultivar Crimson Tide was grafted onto Ferro RZ, Maximus, Nun 9075, RS 841, No:3, Strong Tosa and TZ 148 rootstocks. Non-grafted and self-grafted plants were used as control. Grafting increased the average fruit yield between 17.45% and 52.56% compared to non-grafted treatment. It was concluded that among the tested rootstocks No:3 along with Nun 9075 and TZ 148 rootstocks can be advised due to the increase in fruit yield, total soluble solids and taste panel test values and that the use of grafted plants can be advantageous alternative in watermelon production for producers.
