Tomato Yield

Tomatoes are one of the most consumed vegetables in the world. Unfortunately, obtaining a high quality tomato yield in our latitudes is inconceivable without additional lighting. Changes in biochemical composition are mainly dependent on the light received by the plant. During the winter months, natural daylight at 55 ° latitude is insufficient to provide the necessary vegetation for fruit-bearing vegetables. The aim of this study is to investigate the changes in the biochemical composition of tomato fruits by using less conventional lighting methods, which could offer potential energy savings by providing higher levels of biologically active substances in tomatoes. The study was conducted in a greenhouse of Latvia University of Life Sciences and Technologies during the winter season 2018-2019, using a 16-hour photoperiod. LED, Induction, and High Pressure Sodium Lamps (as control) were used in the study. These lighting devices, with some differences, simulate daylight. Three tomato cultivars: ‘Diamont F1’, Encor F1’and ‘Balzano F1’were studied. The study specified the tomato yield and the following biochemical parameters: soluble sugars (BRIX), vitamin C, organic acids, lycopene, carotenoids, phenols and flavonoids. As expected, the yield and species-specific pigment content of tomato fruit is largely dependent on the genetics of the variety. On the other hand, biologically active compounds such as organic acids, soluble sugars, ascorbic acid and flavonoids undergo more changes due to the composition of the light. The obtained biochemical parameters give an opportunity to consider different illumination methods and the need to carry out further studies in order to confirm the conclusions. Significantly higher yields were observed in the variant with conventionally used high pressure sodium lamps. In mean time, it should be noted that in the variant with LED lamps, higher content of lycopene as well as phenols and vitamin C were observed.

Aims:  To evaluate the potentiality of bio-extract coatings for achieving extended shelf life with enhance fruit quality attributes in pomegranate under ambient storage condition.  Study Design:  The lab experiment conducted in complete randomized design with three repetitions on Mridula cultivar of pomegranate.     Place and Duration of Study:  The experiment was conducted during September 2016 at department of fruit science, Chaudhary Charan Singh Haryana Agricultural University, Hisar, Haryana, India. Methodology: Pomegranate freshly harvested fruits were coated with three bio-extracts coatings viz. Aloe vera (50,75 and 100%), ginger (1,2 and 3%) and mints (10,20 and 30%). The coated fruits were stored at ambient room condition in corrugated fiber board boxes for twelve days.  Periodically effects of bio-extract coatings, storage period and their interaction were observed for physiological loss in weight, decay loss, juice content, TSS: acid ratio, ascorbic acid content and anthocyanin content.    Results: Surface coating with Aloe vera extract 100% was found most effective in reducing physiological loss in weight (50% less reduction as compared to untreated control) whereas ginger extract 3% in reducing the decay loss of fruits (9.65%) as compared to untreated control (23.36%). Among various treatments, the coating of pomegranate fruits with Aloe vera extract 100% resulted in lowest total soluble solids to acid ratio (32.17%) and significantly highest content of juice (47.17%), anthocyanin (13.98 mg/100 g) and ascorbic acid (12.82 mg/100 g) of the fruits along with highest organoleptic rating. The quality attributes viz. total soluble solids to acid ratio, anthocyanin of fruits increased with progression of storage period, while juice content and ascorbic acid decreased. Conclusion: Bio-extract coating of Aloe vera (100%) substantially improved the shelf life with retaining better fruit quality attributes under ambient conditions and has the potential to substitute the prevalent chemical coatings for pomegranate.

The work summarized the literature data on the content of chemicals in blackberries grown in various regions of Russia and foreign countries. Much attention is paid to the level of accumulation of biochemical components: soluble solids, sugars, organic acids, vitamins C (ascorbic acid) and P (phenolic compounds). In the studied regions, a high accumulation of anthocyanins (307-651 mg / 100 g) and ascorbic acid (23.4-54.0 mg / 100 g) in blackberries was noted in the Republic of Adygea. The highest sugar content (9.9%) was in blackberries grown in the middle zone of Russia. The average content of the studied components depends not only on the region of cultivation, but, first of all, on the varietal composition of the crop. The study of 25 blackberry varieties bred in the USA, England and Australia in the Krasnodar Territory allowed us to identify the most adapted of them for cultivation in the south of Russia,the most promising varieties are Thornfree, Smoothstem and Black Satin. In the Republic of Belarus, blackberries are grown on personal subsidiary plots, the most common is the American Agavam variety, which is noted for its high sugar content and the content of P-active substances. At the Maikop Experimental Station. N.I. Vavilov, as a result of studying the biochemical composition of blackberry berries, the following varieties were identified: by the content of dry matter – Oregon, Black Satin, Thornfree; sugar content – Oregon, Silvon, Black Satin, Thornfree, Young; by the content of organic acids – Derrow, Raven (1.67%), Cherokki (1.87%); by the content of ascorbic acid – Himalaya (54.6 mg / 100 g), Derrow (45.8 mg / 100 g), Raven (45.4 mg / 100 g) and Cherokki (47.8 mg / 100 g).

Scientific investigations are being increasingly devoted to biostimulant effects on vegetable yield and quality, with the perspective of sustainable crop management. Two farming systems (conventional or organic) in factorial combination with two biostimulant treatments (tropical plant extract (PE); legume-derived protein hydrolysate (PH)) plus a non-treated control were compared in terms of tomato fruit yield, yield components, mineral composition, functional and nutritional indicators. PE- and PH-based biostimulants resulted in higher plant biomass, PH even in higher leaf area index, compared to non-treated control. Marketable yield was not significantly affected by farming system. PH and PE gave higher yield than non-treated control. PH treatment led to higher fruit number than the control, whereas PE incurred significant increase in yield only under organic farming. The mean fruit weight attained the highest value upon PE application under conventional management. Colour component a* (redness) was higher with the conventional system compared to the organic one, whereas an opposite trend was shown by the organic acids malate, oxalate and isocitrate. Irrespective of the farming system, the soluble solids, fruit brightness (L*) and redness as well as the target organic acids malate, oxalate, citrate and isocitrate were significantly higher than untreated plants by 10.1%, 16.1%, 19.8%, 18.9%, 12.1%, 13.5% and 26.8%, respectively, with no significant differences between the PH- and PE-based biostimulants. Higher lipophilic activity and total ascorbic acid concentration but lower lycopene were recorded under organic management. PE and PH application resulted in higher total phenol and ascorbic acid as well as in lycopene content, and lipophilic antioxidant activity than the non-treated control. Biostimulants proved to be an effective sustainable tool for enhancing tomato fruit yield and functional quality both under conventional and organic vegetable systems.

Apple Fruits

The soluble solids content, level of organic acids, sugars, vitamins and their ratios are the main biochemical indicators of nutritional value that determine the taste of fruits. At the beginning of storage, soluble solids content increases in winter apple varieties, then decreases, and the level of organic acids is mostly reduced due to the active use in respiration. Ascorbic acid is a natural antioxidant, which relatively low content in apples usually reduces during refrigerated storage. The preservation of product’s quality and slowing of ripening achieve by post-harvest treatment of apples with ethylene inhibitor 1-methylcyclopropene (1-MCP), which reduces the loss of soluble solids content, titrated acidity and ascorbic acid. The purpose of the research was to identify the effect of post-harvest treatment of apples with 1-methylcyclopropene on the change in the content of soluble solids, titrated and ascorbic acids in the early winter apple fruits during the extended life cycle at room conditions at the end of long-term storage. Research objects were early-winter apple cultivars ‘Calville’ and ‘Spartan’, treated after harvest with 1-MCP (‘SmartFreshTM’ 0,068 g•m-3) for 24 h at 5 ± 1 ⁰C, during storage at 3 ± 1 ⁰C and relative humidity 85–90 % for two, three, four, five and six months (non-treated fruits – control). Physical-chemical parameters of apple fruits were evaluated monthly at the end of seven days exposure at 20 ± 2⁰C after refrigerated storage. The soluble solids content was determined by refractometer, the content of titrated acids — in recalculation on malic acid - by titration of the aqueous extract, the content of ascorbic acid – by titrimetric method. Data are means of three replicates. It was founded the decrease in soluble solids content of control fruits both varieties as a result of exposure at 20 ± 2⁰C during storage and increase in this indicator for 1-MCP treatment products during the first two and three months of storage with its subsequent decrease. 1-MCP treated fruits contained in twice higher titrated acids content and on 0.51–0.57 mg/100 g significantly higher ascorbic acid content at the end of the seven-day exposure at 20 ± 2⁰C after six months in refrigerator. Consequently, post-harvest 1-MCP treatment is significantly effective for the preservation of the main chemical components’s content of apple fruits at elevated temperature.

Fuji Apple

‘Fuji’ apple (Malus ×domestica Borkh) has gained popularity in the past decades, but poor color of this apple mandates introduction of new strains. To pursue this objective, long-term effects of five ‘Fuji’ apple strains, consisting of ‘Autumn Rose’, ‘Desert Rose’, ‘Myra’, ‘September Wonder’, and ‘Top Export’ on RN 29 rootstock on fruit yield (in 7 years) and harvest time quality attributes (in 6 years) under climate conditions of southwest Idaho were studied during 2004–10. Fruit of ‘September Wonder Fuji’ trees were larger than those of other strains in 5 of 6 years. The type or pattern of peel color among the “low-coloring” and “high-coloring” strains varied widely. Fruits of ‘Autumn Rose Fuji’, ‘Myra Fuji’, and ‘Top Export Fuji’ always had less but ‘September Wonder Fuji’ and ‘Desert Rose Fuji’ had more red color. Fruit of ‘September Wonder Fuji’ had lower firmness but higher starch degradation pattern (SDP) than those of other strains every year as a result of the earlier maturity of this strain. Fruit of ‘Top Export Fuji’ had the lowest SDP among all strains. Fruit of ‘Autumn Rose Fuji’ tended to have lower soluble solids concentration in 3 of 6 years of this study. Considering all yield and quality attributes at harvest, ‘September Wonder’ was a great choice for an early-maturing and ‘Desert Rose’ was suitable for a late-maturing ‘Fuji’ strain. ‘Myra Fuji’ was particularly desirable for its attractive pink color that resembles bagged ‘Fuji’ without the expensive cost of labor associated with bagging.
