Rootstock scion interaction studies on various horticultural attributes of pomato grafts under protected structures. Heliyon 2024; 10:e30930. [PMID: 38779007 PMCID: PMC11109804 DOI: 10.1016/j.heliyon.2024.e30930] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2024] [Revised: 05/07/2024] [Accepted: 05/08/2024] [Indexed: 05/25/2024] Open
Abstract
Pomato is a horticultural wonder plant, as tomato and potato can be produced from a single plant. This experiment explored the influence of diverse graft combinations of tomato scions grafted onto potato rootstocks on various growth and yield-attributing traits. The investigation outcomes confirmed the significantly positive influence of scion grafted onto rootstock on various yielding attributes of tomato and potato harvested from pomato grafts. Scion "Rakshita" grafted onto the rootstock of Kufri Himalini had the maximum fruit length. In contrast, the fruits harvested from the graft combination of Avtar grafted onto Kufri Khyati had the maximum number of fruits per cluster and the number of fruits per plant. The highest average fruit weight, fruit yield per meter square, and total fruit yield quintal per hectare were recorded with control "Avtar. The longest harvest duration was noticed with the graft combination of Heemsohna grafted onto Kufri Himalini. Moreover, on, rootstock Kufri Himalini with scion Rakshita resulted in maximum tuber length, and average tuber weight, while Kufri Himalini with Avtar had maximum fruit width. The maximum number of tubers per plant was also noticed with Kufri Pukhraj with Palam Tomato hybrid -1. The potato harvested from the rootstock of Kufri Pukhraj with Avtar had the highest tuber yield per plant, total tuber yield quintal per hectare, and tuber equivalent yield. The highest survival percentage of grafted plants was noted in Heemsohna onto Kufri Jyoti. In context to the cumulative yield of tomato fruits and potato tubers obtained from the pomato graft was found to be incremented in grafts of Avtar grafted onto Kufri Pukhraj followed by Rakshita grafted onto Kufri Rakshita, which also resulted in the maximum benefit-cost ratio with highest net return and gross return. The graft combination of scion Avtar and Rakshita onto Rootstock Kufri Pukhraj resulted in a positive increment in yield attributing traits of the pomato plant than of control of un-grafted tomato and potato.

Abstract
The consumption of natural foods is increasingly high, and in recent years, consumers have preferred foods from systems with responsible management of natural resources (organic, hydroponic). However, there are still contradictions regarding the nutritional content of products from these different types of crops. Our study aims to compare, for the first time, the content of antioxidants (ascorbic acid, lycopene, total phenolics, essential fatty acids), micronutrients (copper, iron, manganese, zinc), contaminants (cadmium and lead), and free radical scavenging activity between conventional, organic, and hydroponic tomatoes (Solanum lycopersicum) sold in markets in Quito, Ecuador. Ascorbic acid and lycopene were determined by HPLC/UV-Vis. Total phenolics (Folin-Ciocalteu method) and free-radical scavenging activity (2,2-diphenyl-1-picrylhydrazyl method) were determined via UV-Vis spectrophotometry. Lipid profiles were determined as fatty acid methyl esters through a GC-FID. Trace metals were determined using FAAS (micronutrients), and GFAAS (pollutants). No significant differences (p > 0.05) between antioxidant and micronutrient content among the three types of tomatoes were found. Regarding cadmium and lead, the contents were below the Codex Alimentarius threshold limits. Finally, free radical scavenging activity varied slightly (organic > hydroponic > conventional). Although the samples showed certain differences in antioxidant content, none of the tomato types could be considered nutritionally better because of the high variability of the results.

Tsouvaltzis P, Gkountina S, Siomos AS. Quality Traits and Nutritional Components of Cherry Tomato in Relation to the Harvesting Period, Storage Duration and Fruit Position in the Truss. PLANTS (BASEL, SWITZERLAND) 2023; 12:315. [PMID: 36679028 PMCID: PMC9863825 DOI: 10.3390/plants12020315] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Revised: 12/23/2022] [Accepted: 01/05/2023] [Indexed: 06/17/2023]
Abstract
It is well known that the harvesting period and the storage duration have a significant effect on the quality characteristics of cherry tomato fruits. On the other hand, the effect of the fruit position in the truss has not been studied, as well as the relative contribution of each one of these factors on fruit quality. For this purpose, cherry tomato (Genio F1) whole trusses were harvested at the fruit red ripe stage during three periods. At each harvesting period, the first four (at the base of the truss) and the last four (at the top) fruits from each truss that was previously trimmed to 10 fruits, were stored at 12 °C for 0, 4 and 10 days. At the end of each storage duration, the external color, firmness, antioxidant capacity, pH and titratable acidity, as well as dry matter, soluble solid, total soluble phenol, lycopene, total carotenoid and β-carotene content, were determined. Analysis of variance (ANOVA) indicated that the harvesting period had the most significant effect on skin color parameters L * and C * and β-carotene, as well as on antioxidant capacity, total soluble phenols, dry matter and total soluble solids, while it also had an appreciable effect on titratable acidity. The storage duration had a dominant effect on firmness, total carotenoids and lycopene, while it had an appreciable effect on skin color parameter L * as well. On the other hand, the fruit position in the truss exerted an exclusive effect on ho and a */b * ratio skin color parameters and pH and an appreciable effect on titratable acidity.
