Effects of aminoethoxyvinylglycine treatment by vacuum infiltration method on postharvest storage and shelf life of tomato fruit
No full textWOS: 000392779700002The aim of this study was to determine effects of postharvest aminoethoxyvinylglycine (AVG) treatment using vacuum infiltration method on retardation of ripening, storage and shelf life of tomato fruit. In the Experiment-1, beefsteak 'Grando F1' tomato fruit was harvested at breaker stage and treated with AVG at six different doses (0, 62.5,125, 250, 500 and 1000 mg L-1) and three different vacuum pressures (0 kPa, -20 kPa and -30 kPa) using vacuum infiltration method and kept at 20 degrees C for 8 d. The AVG treatment of 1000 mg L-1 at -30 kPa reduced ethylene production rate by 45.53%, delayed color changes and extended the number of days reaching to red ripe stage from 6 to 8 d at 20 degrees C and was confirmed as the optimal treatment for the maximum retardation of tomato fruit ripening by response surface methodology. In Experiment-2, untreated and treated breaker 'Grand F1' tomato fruit with 1000 mg L-1 at -30 kPa were kept at 12 degrees C for 0, 5, 10, 15 or 20 d and for 2 d at 20 degrees C after cold storage. AVG treated fruit had lower ethylene production rate, lycopene content, a* and C* values and higher fruit firmness, chlorophyll content, L* and h degrees values, compared to control during storage and shelf life period. For shipping to distant markets, storage and shelf life of untreated fruit were 10 d at 12 degrees C plus 2 d at 20 degrees C while AVG treatment extended storage and shelf life to 20 d at 12 degrees C plus 2 d at 20 degrees C.

Phytochemical characteristics of grafted watermelon on different bottle gourds (Lagenaria siceraria) collected from the Mediterranean region of Turkey
No full textThe objective of this study is to determine the sugar, organic acid, and carotenoid content of Crimson Tide watermelons grafted onto bottle gourd genotypes collected from the Mediterranean region of Turkey. The experiment was carried out during the 2008 and 2009 growing season. Grafting on the local bottle gourd rootstocks improved the total soluble solid (TSS), titratable acidity (TA), TSS/TA ratio, sugar, organic acid, and carotenoid (beta-carotene and lycopene) contents of Crimson Tide fruits. Grafting also altered the ratios among the sugars of Crimson Tide watermelon fruits. Among the Crimson Tide/rootstock (CT/rootstock) combinations, the CT/09-01 and CT/07-06 graft combinations with higher sucrose, lycopene, and total carotenoid content were found promising to increase the quality of Crimson Tide fruits. Commercial rootstocks (Macis and Argentario) reduced carotenoid content compared to the control.

Volatile organic compounds in watermelon (Citrullus lanatus) grafted onto 21 local and two commercial bottle gourd (Lagenaria siceraria) rootstocks
No full textVolatile organic compounds (VOCs) are responsible for flavour development in watermelon (Citrullus lanatus). The objective of this study was to investigate the rootstock effects of 21 local bottle gourd [Lagenaria siceraria (Molina) Standl.] accessions collected from the Mediterranean region (Turkey) on the concentrations of VOCs in watermelon over 2 years. The watermelon cultivar 'Crimson Tide' was used as the scion and two commercial bottle gourd rootstocks were also used for comparison. The VOCs in each rootstock-scion combination were analysed using static headspace (SHS) and gas chromatography-mass spectrometry (GC-MS). A total of 24 VOCs were identified in watermelon fruit, including 11 aldehydes, seven alcohols, four ketones, one heterocyclic compound, and one acid. Acetaldehyde (25.9 - 39.5% of the total peak areas), propanal (5.0 - 8.3%), 2-propanone (2.5 - 4.9%), pentanal (2.1 - 3.6%), hexenal (14.5 - 22.6%), (E)-2-hexenal (0.4 - 2.3%), 6-methyl-5-hepten-2-one (10.0 - 19.05%), nonanal (1.6 - 4.4%), (Z)-6-nonenal (4.0 - 9.8%), (E)-2-nonenal (0.6 - 2.0%), (E,Z)-2,6-nonadienal (2.1 - 3.7%), (Z)-6-nonenol (1.0 - 3.2%), and (E,Z)-3,6-nonadienol (1.0 - 3.7%) were the most abundant VOCs found in all watermelon scions. There was no significant effect (P >= 0.05) of rootstock on the concentrations of acetaldehyde, propanal, pentanal, heptanal, ethanol, 1-pentanol, 2-propanone, 2-pentyl furan, or acetic acid. Propanal, 2-propanone, and acetic acid were identified as VOCs in watermelon for the first time. Hexanal, (Z)-6-nonanal, and 6-methyl-5-hepten-2-one concentrations were strongly affected by rootstock. The results showed that the local bottle gourd accessions 07-06 and 31-09, in particular, were the most promising genotypes in terms of producing favourable VOCs. Except for the local bottle gourd accessions 33-35, 01-17, and 07-04, the other 18 gourds accessions had high potential as rootstocks for breeding programmes in watermelon with regard to desirable VOC concentrations. Rootstock 31-09 should be considered for commercial production in terms of improved disease resistance, fruit yield, and fruit quality.

Rootstocks effect on plant nutrition concentration in different organ of grafted watermelon
No full text In this study carried out in 2009 and 2010 grow-ing seasons, effect of rootstocks on plant nutri-tion partitioning in grafted watermelon onto four gourd rootstocks was investigated. Ferro, RS841 (Cucurbita maxima x C. moschata) and Argentario and Macis (Lagenaria hybrid) were used as rootstocks. Crimson Tide and Crisby watermelon cultivars were used as scion. Grafted and ungrafted seedlings were produced by a commercial seedling company. Plants were grafted by one cotyledon grafting techniques. Experiment was conducted in Alata Horticultural Research Station in Mersin. The grafted plants were planted under low tunnel in early spring and regular cultural practices for watermelon were applied. Plant nutrition concentrations were determined in leaf, fruit rind, fruit flesh and seeds. Leaf sample was taken at flowering stage, rind, flesh and seed sample were taken from fully mature fruit. Nitrogen concentration was determined by modified Kjheldahl methods. Phosphorous concentration was determined by vanadomolybdophosphoric acid method. K, Ca, Mg, Fe, Mn, Zn and Cu concentration of samples were determined by atomic absorption spec-trophotometry. Plant nutrient concentration in leaf, rind, flesh and seed were significantly af-fected by rootstocks. Increase in concentration of N, P, K, Ca and Mg in leaves was not observed in grafted plant. Ungrafted plant had higher concentration of Fe, Mn, Zn and Cu in their leaves. Ca concentration in rind of fruits from grafted watermelon was higher than ungrafted control plant except Crimson Tide/Macis and Crimson Tide/Argentario graft combinations. Plant nutrition content of fruit flesh was significantly affected by rootstocks and scion. Magnesium, Fe, Zn and Mn concentration of seed was not significantly influenced by rootstocks and scion while other plant nutrient content was signifi-cantly affected rootstocks and scion. </p
Effects of rootstocks on storage performance of Nova mandarins
Get PDFIn this research, the effects of rootstocks on the storage performance of Nova mandarins grafted on Carrizo citrange, Troyer citrange, or sour orange grown in the ecological conditions of Dortyol were studied. Fruits were harvested at optimum maturity and kept at 4 degrees C and 6 degrees C for 120 days. Changes in weight loss, incidence of fungal decay and physiological disorders, juice content, total soluble solids (TSS), percent fruit with green button, titratable acidity (TA), juice pH, vitamin C content, and rind color (L-star, C-star, h degrees) were monitored at 15-day intervals during storage to determine the effects of rootstock on postharvest quality of Nova mandarins. The fruit of Nova mandarin grafted on sour orange and Carrizo citrange had higher weight loss than Troyer citrange. Weight loss from Nova mandarins kept at 4 degrees C and 6 degrees C reached 7.71% and 12.21%, respectively, after 120 days of storage. Juice pH, incidence of fungal decay, and physiological disorders increased, while juice content, TA, vitamin C content, percent fruit with green button, and L-star, C-star, and h degrees values of rind color decreased in the Nova mandarin cultivar during cold storage. According to the data, the fruits of Nova mandarin grafted on Carrizo citrange, Troyer citrange, or sour orange were stored better at 4 degrees C than 6 degrees C. Fruit could be kept at 4 degrees C for 75 days and at 6 degrees C for 45 days without any quality deterioration

Among 210 accessions, 72 genotypes were selected based on morphological characteristics. Two commercial hybrid rootstocks were also used for comparison. Crimson Tide watermelon cultivar was used as a scion. Emergence rate, hypocotyl morphology, survival rate, and resistance to Fusarium oxysporum f. sp. niveum (FON) were investigated. Grafted plants were grown for 3 weeks in order to investigate the effect of rootstocks on plant growth. Leaf number, shoot dry weight, and root dry weight were determined. Emergence rate was ranked between 72% and 100% in collected genotypes. The highest graft compatibility was 99% while the lowest graft compatibility was 70%. All the grafted plants showed better performance than control plants regarding plant growth. All bottle gourd genotypes were tested against known 3 races of FON and all of them showed resistance against it. However, 9 genotypes showed yellowing but reisolation from those plants showed that yellowing was not due to FON. Crimson Sweet watermelon cv. susceptible to 3 races of FON was grafted onto 10 Lagenaria siceraria genotypes with the highest graft compatibility with watermelon. While all grafted plants showed resistance to FON, ungrafted Crimson Sweet watermelon cv. was found susceptible to 3 races of FON. The results showed that Turkish L. siceraria germplasm has powerful rootstock potential for watermelon against Fusarium wilt and it is a good resource for rootstock breeding programs.</p
Storage and self life of grafted watermelon
No full textWatermelon [Citrullus lanatus (Thunb.) Matsum. & Nakai] fruits from ‘Crimson Tide’ (CT) grafted onto Ferro, RS841, Argentario, and Macis rootstocks and ungrafted CT were compared for their postharvest quality after the following treatments: (1) 7 days at 21°C; (2) 7 days at 27°C; (3) 21 days at 0°C; (4) 21 days at 0°C and subsequent 7 days at 21°C; (5) 21 days at 7°C and (5) 21 days at 7°C and subsequent 7 days at 21°C. Ungrafted CT and the CT/Macis fruits seem to be more susceptible to CI. Grafting did not affect weight loss and incidence of fungal decay and TSS content in watermelon fruits, but affected changes in flesh color and firmness, and pH during storage and shelf life period. Control, the CT/Macis and CT/Argentario fruits were softer than other combinations at harvest and during storage and shelf life. Fruits did not exhibit CI symptoms during 7°C storage and subsequent shelf life period in all combinations, but fungal decay may limit storage and shelf life
Plant Growth Characteristics in Watermelon Grafted onto Different Bottle Gourds (Lagenaria siceraria) Collected from Southern and Western Part of Turkey
No full textWe studied the plant characteristics of Crimson Tide (CT) watermelon cultivar was grafted onto 21 bottle gourds (Lagenaria siceraria (Malign) Stanley) landraces collected from southern and western part of Turkey and two commercial hybrid rootstocks [Argentario (Arg) and Macis]. Grafted plants were grown in eight-l pot filled with mixture of peat:perlite (2:1) in unheated greenhouse for six weeks in spring season of 2008. Plants were harvested six weeks after transplanting. We determined rootstock and scion hypocotyl diameter, main stem diameter, main stem length, leaf number, leaf area, fresh and dry weight of root, aerial parts of plants and fruit. All the grafted plants had thicker rootstocks, scion and main stem diameter than ungrafted control plants. Grafted plants had higher values than control plants as regarded to main stem length, leaf number, leaf area, fresh and dry weight of roots, aerial parts of plants and fruit. In general, all the grafted plants produced two to three folds more biomass than the ungrafted control plants
