Improved Yield, Fruit Quality, and Shelf Life in ‘Flame Seedless’ Grapevine with Pre-Harvest Foliar Applications of Forchlorfenuron, Gibberellic Acid, and Abscisic Acid

AbstractThe effect of gibberellic acid (GA3), forchlorfenuron (CPPU), and abscisic acid (ABA) on the parameters of yield of ‘Flame Seedless’ grapes was investigated. The clusters of 8-year-old grapevines were sprayed with solutions: GA3 at 25 mg·dm−3, CPPU at 10 mg·dm−3, and ABA at 300 mg·dm−3, alone or in combinations. GA3 and CPPU treatment increased yield, cluster weight and length, berry weight and diameter, as well as fruit firmness, but reduced the total soluble solids (TSS) and intensity of berry color. Anthocyanin content of berries treated with GA3 and CPPU increased significantly by ABA treatment. Shelf life was increased by GA3 and CPPU treatments, as they decreased the percentage of weight loss, shattering, and unmarketable berries after storing at 20 °C for 7 days. Thus, it can be concluded that the combined use of GA3, CPPU, and ABA may be an efficient practice for fruit enlargement, coloration, and keeping quality in ‘Flame Seedless’ grape.

Vineyard rootstocks are an important tool in the local and international market for growing the Superior Seedless grape cultivar, which is highly favored by customers. As a result, it is vital to pay close attention to the quality of clusters during handling. The current study aimed to determine whether Superior Seedless vines can be grown on specific rootstocks, resulting in higher quality during shelf life. Vines of the Superior Seedless vine cultivar that were used were 13 years old and had been grown on sandy soil. These vines were grafted onto four different rootstocks (genotypes), namely Freedom, 1103 Paulsen, SO4, and Own Root. The soluble solids content (SSC%) was selected as 16%. Bunches were subsequently stored in the lab at 27 ± 1 °C with 57 ± 3% air relative humidity for three days. Rootstock 1103 Paulsen’s quality was found to be superior to that of the other rootstocks, according to the results of the study. Rootstock 1103 Paulsen maintained its ascorbic acid (AA) content, which is reflected in its antioxidant capacity, according to the results. In addition, lipid peroxidation accumulation and ion leakage percentages indicated that oxidative reactions were at their lowest levels. The results show that 1103 Paulsen decreases cellular metabolism enzyme activities at the shelf life level and improves the bunch quality of Superior Seedless (scion) grapes within 4 days of application. As a whole, the results show that the 1103 Paulsen rootstock produces Superior Seedless bunches of a high quality that is preserved throughout the shelf life period.

The purpose this work was to evaluate the influence of pre-harvest application of plant biostimulant on the quality and shelf-life of melon. For this an experiment was established in the “Coopyfrutas”, located in Rio Grande do Norte state/Brazil. The treatments consisted of a combination of factors: melon cultivars (‘Goldex’ and ‘Iracema’) and pre-harvest application of plant biostimulant, Crop Set®, (with and without). At commercial maturity, some fruit of each treatment were sampled and analyzed and the others were stored in a cold chamber at 10±2 ºC and 80±2% relative humidity. The experiment was arranged in a completely randomized split-plot design. The plots consisted of cultivars and Crop Set® application and subplots of different storage time (0, 14, 21, 28, and 35 days after harvest) with eight replications. The characteristics evaluated were length, diameter, internal cavity, external and internal appearance, weight loss, fresh firmness, soluble solids, titratable acidity, pH, SS/TA ratio, and total soluble sugars. Applications of plant biostimulant led to an increase in fruit length and diameter. It reduced fresh firmness and increased the pH of ‘Goldex’ fruit. The total soluble sugars reduced at 35 days of storage in the ‘Iracema’ fruit treated with plant biostimulant.

An experiment was conducted to evaluate the changes in the chemical properties of banana fruits and their shelf life as influenced by different postharvest treatments. There were two varieties viz. Amritasagar (VI) and Sabri (V2) and seven storage treatments viz.: control (open space, 30±2ºC) (T0); perforated polyethylene, 30±2ºC (T1); non-perforated polyethylene, 30±2ºC (T2); benzyl adenine (BA 30 ppm, 30±2ºC) (T3); gibberellic acid (GA3 150 ppm, 30±2ºC) (T4); benzyl adenine (BA 30 ppm, 15°C ) (T5) and gibberellic acid (GA3 150 ppm, 15°C) (T6). A factorial experiment was laid out in the Completely Randomized Design (CRD) with three replications. Data were recorded on titratable acid content, total sugar content, reducing sugar content, non-reducing sugar content, total soluble solids and pulp pH. Among the chemical parameters, total soluble solids (TSS) and pH of pulp increased while titratable acidity decreased during storage in all the treated and untreated banana fruits. Among the treatments gibberellic acid (GA3 150 ppm, 15°C) treatment exhibited the best storage performance. The treatment combinations of Sabri with gibberellic acid (GA3 150 ppm, 15°C) showed the longest shelf life (16.25 days), whereas the lowest shelf life was in Amritasagar with control (open space, 30±2ºC) treatment combination (6.78 days).The Agriculturists 2014; 12(2) 06-17

Quality And Shelf Life

Banana is a climacteric fruit with a short shelf life. As a result, huge losses are incurred during handling in the value chain. The need to develop means of extending the shelf life and concomitantly maintaining the quality of the fruit after harvest has become very important. This study was conducted to determine the effects of two different edible waxing materials (beeswax and cassava starch) used as coatings on the quality and shelf life of Mysore banana. The study was conducted in the laboratory at the Department of Horticulture, Kwame Nkrumah University of Science and Technology–Kumasi. The experiment was laid out in a simple completely randomized design (CRD) and replicated three (3) times with three treatments (beeswax, cassava starch and a control). Parameters studied were: fruit weight loss, firmness, peel colour, pulp-to-peel ratio, moisture content (MC), dry matter content (DMC), total titratable acidity (TTA), total soluble solids (TSS), pH, green life and shelf life. The results showed beeswax and cassava starch had no significant effect (P>0.01) on peel colour, fruit firmness, TTA, TSS, DMC, MC and green life. Beeswax, however, kept weight loss minimal, and reduced TSS and the pulp-to-peel ratio of the fruits during storage. We conclude that beeswax was the best treatment in terms of waxing Mysore banana fruits to maintained its quality and ultimately prolonged its shelf life by about four (4) days more than the control.

Abstract The adoption of melon hybrids by the productive sector necessitates a prior evaluation of the productivity, quality and shelf life of their fruits. Due to the different environmental conditions under which the hybrids are evaluated, an accentuated genotype-environmental interaction is expected to become apparent and likewise play important role in manifestation of phenotypic traits. The objective of the present work was to evaluate melon hybrids in the state of Rio Grande do Norte. The adaptability and stability of the genetic values were estimated by the HMRPGV method (Harmonic Mean of the Relative Performance of Genetic Values) for the following traits: yield, and soluble solids (SS) content in the period between 2010 to 2015. In 2017, the more promising melon hybrids from previous trials were evaluated under commercial conditions to determine the fruit’s yield, quality and shelf life. The predominance of the complex part of the genotype-environmental interaction was verified for both yield and SS content. Hybrids HC-02 and HC-11 show promising traits when grown under the conditions of the Mossoró-Assu Agricultural Complex owing their high stability, adaptability, yield, and fruit quality. Hybrids HC-02, HC-11, and ‘Hy Mark’ are suitable as international exports due to their long shelf life.

Seedless Grapes

Forchlorfenuron (CPPU), a synthetic cytokinin, applied after fruit set increases the size and firmness of table grapes (Vitis vinifera L.) beyond what is possible without CPPU treatment. However, treatment with CPPU may inhibit coloring of ‘Flame Seedless’ grapes, limiting its use in growing areas where color has been consistently poor. In contrast, application of abscisic acid (ABA) to ‘Flame Seedless’ grapes may cause fruit softening, which is undesirable, but its primary effect is to increase anthocyanin content and fruit color. Thus, we hypothesized that application of CPPU followed by ABA might increase the size and firmness of ‘Flame Seedless’ grapes without excessively inhibiting coloring. Grapes were treated with 0 or 20 g·ha−1 CPPU (applied at fruit set) and 0, 300, or 600 mg·L−1 ABA (applied at veraison) in 2005 and with 0, 5, 10, 15, or 20 g·ha−1 CPPU and 0, 200, 400, or 600 mg·L−1 ABA in 2006. Both plant growth regulators (PGRs) increased berry mass, but grapes treated with CPPU were as firm, or firmer, than nontreated grapes, whereas those treated with ABA were of similar or lesser firmness. Treatment with CPPU generally reduced soluble solids and red berry color, whereas treatment with ABA reduced titratable acidity and increased red color. The PGRs did not interact to affect any of the fruit quality variables measured, so beneficial effects of CPPU or ABA were apparent whether the grapes were treated with either or both PGRs. Thus, the combined use of CPPU and ABA may be a desirable cultural practice for ‘Flame Seedless’.

Aim of study: To evaluate the use of compost and natural rocks as partial replacement of mineral fertilizers in ‘Flame’ seedless grape vineyards.Area of study: The present work was conducted during three successive seasons (2016, 2017 and 2018), being the first season a preliminary trial on 4-yr old grapes cultivated in two different soil types (sandy and clay) at two different locations, Egypt (Abo Galeb, Giza governorate; EL-Mahala, Gharbia governorate).Material and methods: Treatments were applied as natural raw materials at 20, 40, 60, 80 and 100% out of recommended mineral NPK rate. The mineral fertilizers used were ammonium sulfate (21.6% N), calcium super phosphate (15.5% P2O5) and potassium sulfate (48% K2O). The natural rocks used were phosphate rock (22.0% P2O5) and Feldspar (10.12% K2O). Yield and fruit characteristics and leaf mineral content were determined.Main results: Using compost in combination with natural rocks enriched with NPK mobilization bacteria and mineral NPK enhanced leaf nutrients content and gave the highest yield and cluster weight. This mix also improved berries physical and chemical characteristics. There was an increase in soluble solids content (SSC), SSC/acid ratio, and anthocyanin content, associated with a reduction in nitrate content of the berry juice. The most pronounced effect was related to using 60% mineral fertilization + 40% organic and natural rocks in both vineyard locations.Research highlights: We can reduce the recommended doses of mineral NPK by about 40%, reducing then the soil pollution.
