The density of herbaceous crops creates a suitable environment to produce pathogens in the soil that intensify the attack of pathogens traditionally controlled by disinfectant, which are mostly prohibited and unlisted because of their toxicity. Grafting is an alternative technique to enhance abiotic stress tolerance and reduce root diseases due to soil-borne pathogens, thus enhancing crop production. This research study was conducted during the crop season of 2017 and 2018 in order to investigate the interactive effect of different grafting techniques of hybrid scion onto local rootstocks on plants survival, plant phenological growth, fruit yield and fruit quality under a controlled environment. The hybrid cucumber was also planted self-rooted. The cucumber (Cucumis sativus L.) cv. Kalaam F1, Syngenta was grafted onto four local cucurbitaceous rootstocks; ridge gourd (Luffa operculate Cogn.), bitter gourd (Momordica charantia L.), pumpkin (Cucurbita pepo L.), bottle gourd (Lagenaria siceraria (Molina) Standl.) using splice grafting, tongue approach, single cotyledon and hole insertion grafting techniques and self-rooted hybrid cucumber under greenhouse conditions. The experimental results indicated that all local cucurbitaceous rootstocks showed a high compatibility with hybrid cucumber scion in the splice grafting method compared to other grafting and non-grafted methods. Lagenaria siceraria rootstocks were found highly compatible with cucumber cv Kalaam scion which gave significantly maximum plant survival rates (95%) due to high sap contents, high SPAD value, better vegetative growth and maximum fruit yield when compared with other rootstocks by employing the splice grafting method followed by tongue approach, single cotyledon and hole insertion grafting while the fruit quality of all rootstocks was observed to be similar. The non-grafted cucumber cv. Kalaam F1 showed significant results of plant vegetative growth, fruit development and fruit quality and encountered grafting methods while the lowest result were associated with the hole insertion grafting method in all scion/rootstock combinations. The grafted plants have no significant effect on cucumber fruit dry matter and fruit quality while the fruit mineral compositions (N, P, K, Ca and Mg) were higher among grafted and non-grafted plant fruits. The results indicate that grafting hybrid cucumber onto four local cucurbitaceous rootstocks influenced growth, yield and fruit quality. Grafting can be alternative and control measure for soil-borne disease and to enhance cucumber production.

Sand culture experiments were conducted in controlled environments to determine the effects of endogenous fruit Ca concentration on tissue firmness and the rates of softening following fresh-pack processing of pickling cucumbers. Fruit Ca status was modified by exposing the cucumber plants to 0.01, 0.1, 10, and 20 mM Ca in the nutrient solutions from fruit set to harvest. Ca concentrations were measured in pericarp and endocarp tissue. Spears were 4.5 cm diam. fruit were fresh-pack processed in 0, 5 or 20 mM CaCl2 solutions. Tissue texture during incubation at 46°C was measured at 0, 5 and 20 days using a shear press (TMS-90, Food Tech. Corp.). Pericarp tissue Ca concentrations were positively correlated with tissue firmness immediately following fresh-pack processing. High endogenous Ca levels, however, were correlated with high rates of pericarp softening during accelerated aging. Refrigeration extended the Ca effect on texture for 3 weeks following processing.

The objective of this research was to evaluate the production and phytochemical quality of cucumber fruits (Cucumis sativus), in response to the foliar application of different seaweed extracts. This study was carried out under shadow mesh conditions in the autumn - winter agricultural cycle at Instituto Tecnológico de Torreón, Torreón, Coahuila. The experimental design was completely random, using six treatments with six repetitions each. The treatments evaluated were: Macrocystis pyrifera, Bryothamnion triquetrum, Ascophyllum nodosum, Grammatophora sp., Macrocystis intergrifolia, and a control treatment with inorganic fertilization. The substrate used was a mixture of sand and vermicompost. The yield, commercial quality and phytochemical compounds of the fruit were evaluated.  Results showed that yield using Steiner solution (6.75 kg m−2) was higher than that obtained with Bryothamnion triquetrum algae (6.07 kg m−2). Regarding the phenolic content, the extracts surpassed the control treatment, with Macrocystis pyrifera and Macrocystis integrifolia being statistically equal, with values of 47.37 and 43.73 mg equiv. of Ac. Gallic 100 g fresh weight, respectively. The antioxidant capacity by ABTS+ and DPPH+ methods was higher using the treatment with algae Macrocystis pyrifera with 149.4 and 454.1 μM equiv Trolox/100 g fresh base, respectively. This treatment also presented the highest value of vitamin C with 5.07 mg/100 g fresh base, being 27% greater than the control treatment. Algae extracts increased the quality of the fruits by obtaining the highest antioxidant capacity, making their use a viable option to minimize the application of conventional fertilizers, thereby attenuating the effects on the environment and improving the health of the population.

Rootstocks frequently exert detrimental effects on the fruit quality of grafted cucumber (Cucumis sativus L.) plants. To understand and ultimately correct this deficiency, a transcriptomic and metabolomic comparative analysis was performed among cucumber fruits from non-grafted plants (NG), and fruits from plants grafted onto different rootstocks of No.96 and No.45 (Cucurbita moschata. Duch), known to confer a different aroma and taste. We found remarkable changes in the primary metabolites of sugars, organic acids, amino acids, and alcohols in the fruit of the grafted cucumber plants with different rootstocks, compared to the non-grafted ones, especially No.45. We identified 140, 131, and 244 differentially expressed genes (DEGs) in the comparisons of GNo.96 vs. NG, GNo.45 vs. NG, and GNo.45 vs. GNo.96. The identified DEGs have functions involved in many metabolic processes, such as starch and sucrose metabolism; the biosynthesis of diterpenoid, carotenoid, and zeatin compounds; and plant hormone signal transduction. Members of the HSF, AP2/ERF-ERF, HB-HD-ZIP, and MYB transcription factor families were triggered in the grafted cucumbers, especially in the cucumber grafted on No.96. Based on a correlation analysis of the relationships between the metabolites and genes, we screened 10 candidate genes likely to be involved in sugar metabolism (Fructose-6-phosphate and trehalose), linoleic acid, and amino-acid (isoleucine, proline, and valine) biosynthesis in grafted cucumbers, and then confirmed the gene expression patterns of these genes by qRT-PCR. The levels of TPS15 (Csa3G040850) were remarkably increased in cucumber fruit with No.96 rootstock compared with No.45, suggesting changes in the volatile chemical production. Together, the results of this study improve our understanding of flavor changes in grafted cucumbers, and identify the candidate genes involved in this process.

ABSTRACT Cucumber is a horticultural product which becomes one type of fruit vegetable and has a great demand in the community. The potential productivity of cucumber itself is still relatively low, that is in 2016 amounting to 10.19 tons / ha, this also occurs in the productivity of local cucumbers which are quite low, but until now there are still many cultivated by farmers in Jember area. In addition to the increase in production, it is also necessary to improve the quality of fruit which affects the competitiveness of the selling value of cucumber fruit. Regarding the increase in production and quality of fruit, the efforts need to be made to improve cultivation methods. One of them is the use of organic fertilizers which contain more complex nutrients and the application of plant regulators. One of the organic fertilizers, vermicompost organic fertilizer, is the result of decomposition by worms which affects plant growth and the application of gibberellins (GA3), it can improve fruit quality and increase the percentage of fruit formation. This study aimed to determine the effect of using the combination of vermicompost organic fertilizer and the addition of giberelin (GA3) on cucumber plants by using a randomized group design (RGD) with 2 factors and 3 replications. The first factor was giving vermicompost organic fertilizer, namely (K0) 0 g/plant (control), (K1) 120 g/plant (3 tons/ha), (K2) 240 g/plant (6 tons/ha), (K3) 360 g/plant (9 tons/ha). The second factor was the addition of gibberellin concentrations (GA3), namely (G0) 0 ppm, (G1) 50 ppm, (G2) 100 ppm and (G3) 150 ppm. The data obtained were then analyzed using variance analysis, if between treatments had a significant difference, then further tests were carried out by using Duncan's Multiple Distance Test at the level of 5%. The best treatment ofvermicompost organic fertilizer dosage and giberelin hormone concentration was found in the treatment of 360 g/plant or 9 tons/ha (K3) at the optimal concentration of 100 ppm giberelin hormone. Key words: Cucumber, Vermicompost fertilizer, Gibberellin (GA3), Production and Quality of Fruit ABSTRAK Mentimun merupakan produk hortikultura yang menjadi salah satu jenis sayuran buah yang banyak diminati oleh masyarakat. Potensi produktivitas mentimun sendiri masih tergolong rendah yaitu pada tahun 2016 sebesar 10,19 ton/ha, hal ini juga terjadi pada produktivitas mentimun jenis lokal yang cukup rendah, namun sampai saat ini masih banyak dibudidayakan oleh petani pada daerah Jember. Selain peningkatan terhadap produksi, perlu juga dilakukan perbaikan kualitas buah yang berpengaruh pada daya saing nilai jual buah mentimun. Terkait peningkatan produksi dan mutu buah, maka perlu dilakukan upaya perbaikan cara budidaya. Salah satunya adalah penggunaan pupuk organik yang mengandung unsur hara yang lebih kompleks dan pengaplikasian zat pengatur tumbuhan. Salah satu pupuk organik yaitu pupuk organik kascing, yang merupakan hasil dekomposisi oleh cacing yang berpengaruh terhadap pertumbuhan tanaman dan aplikasi giberelin (GA3) yang mampu meningkatkan kualitas buah dan meningkatkan persentase pembentukan buah. Penelitian ini bertujuan untuk mengetahui pengaruh kombinasi penggunaan pupuk kascing dan pemberian hormon giberelin (GA3) pada tanaman mentimun, menggunakan Rancangan Acak Kelompok (RAK) dengan 2 faktor dan 3 ulangan. Faktor pertama pemberian dosis pupuk kascing yaitu, (K0) 0 g/tanaman (kontrol), (K1) 120 g/tanaman (3 ton/ha), (K2) 240 g/tanaman (6 ton/ha), (K3) 360 g/tanaman (9 ton/ha). Faktor kedua pemberian konsentrasi giberelin (GA3) yaitu (G0) 0 ppm, (G1) 50 ppm, (G2) 100 ppm dan (G3) 150 ppm. Data yang diperoleh selanjutnya dianalisis menggunakan analisis sidik ragam, jika antar perlakuan mengalami perbedaan yang signifikan, maka dilakukan uji lanjut dengan menggunakan Uji Jarak Berganda Duncan pada taraf 5%. Perlakuan dosis pupuk kascing dan konsentrasi hormon Giberelin terbaik terdapat pada perlakuan 360 g/tanaman atau 9 ton/ha (K3) pada konsentrasi optimal hormon giberelin 100 ppm.

Reported Data

A process was started in the late 1990s to produce comprehensive environmental data on particular aspects of Finnish food production with the aim of analyzing the environmental impacts (at least climate change, acidification and eutrophication and some other impacts) of products and locating hot spots in production chains. A supply chain integrated life cycle assessment was carried out on fodder barley, hard cheese, oat flakes, potato flour, cream cheese potato gratin, beer, honey-marinated/sliced broiler fillet and greenhouse cucumber. Methodological improvements in assessing environmental impacts of food products were evaluated in relation to ISO14040 and 14044 standards. Methods improved, especially regarding quality of cultivation data and previously reported data from the literature, impact assessment and calculations for assessment of leaching from agriculture. As a generic conclusion on the share of contributions of the various phases of production chains to environmental impact: agriculture was the most important phase, especially in terms of eutrophication potential. Work in food LCA methodology has provided a sound base for future development in assessing environmental impacts of food products. In the future providing more and more environmental information on products for customers and consumers is setting new challenges for research.;
