Pericarp Browning

Background: Phospholipase D (PLD)is closely related to browning and senescence of postharvest longan fruit. Objective: This study investigated the effects of 2-butanol (a PLD inhibitor) on the expression and regulation of PLD during storage of longan fruit at a low temperature. Methods: Senescence-related quality indices showed that the 2-butanol-treated fruit presented lower pericarp browning index, pulp breakdown index and total soluble solid value than the untreated fruit. Results: The fruit treated by 60 µL/L 2-butanol exhibited the strongest inhibition on senescence, which significantly delayed changes in weight, titratable acidity content, total soluble solid content and ascorbic acid content. This treatment maintained a high level of total phenolic content and caused significant inhibition on pericarp browning and pulp breakdown. Through ELISA method, 60 µL/L 2-butanol treatment also reduced PLD activity. Real-time RT-PCR (RT-qPCR) results showed that PLD mRNA expression level was inhibited by 60 µL/L 2-butanol within 15 days. Western-blotting results further confirmed the differential expression of PLD during storage, and a relatively higher expression for PLD protein was found in control compared to the 2-butanoltreated fruit during 15-d storage. Conclusion: These results provided a scientific basis and reference to further investigating postharvest longan quality maintenance by regulating the PLD gene expression.

The cracking of sweet cherries causes significant crop losses. Sweet cherries (cv. Bing) were coated by electro-spraying with an edible nanoemulsion (NE) of alginate and soybean oil with or without a CaCl2 cross-linker to reduce cracking. Coated sweet cherries were stored at 4 °C for 28 d. The barrier and fruit quality properties and nutritional values of the coated cherries were evaluated and compared with those of uncoated sweet cherries. Sweet cherries coated with NE + CaCl2 increased cracking tolerance by 53% and increased firmness. However, coated sweet cherries exhibited a 10% increase in water loss after 28 d due to decreased resistance to water vapor transfer. Coated sweet cherries showed a higher soluble solid content, titratable acidity, antioxidant capacity, and total soluble phenolic content compared with uncoated sweet cherries. Therefore, the use of the NE + CaCl2 coating on sweet cherries can help reduce cracking and maintain their postharvest quality.

Two trials in different agricultural farms were carried out from October 2014 to June 2015 with the aim to assess the advantages linked to the substitution of the low density polyethylene (LDPE) films for soil mulching with the Mater-Bi<sup>®</sup> biodegradable films in the strawberry cultivation under tunnel in Campania. Lifetime of biodegradable mulch and influence of type of mulch on the yield and the quality of cvs Sabrina and Fortuna were evaluated. Plants were cultivated on mulched, raised beds, high 40 cm from bottom soil. Mater-Bi<sup>®</sup> film was 20 <span>µ</span>m thick while LDPE film was 50 mm thick. The physical-chemical parameters (firmness, pH, total soluble solid content, titratable acidity and skin colour) and some bioactive compounds (total polyphenols, flavonoids, anthocyanins, antioxidant activity) of fruits were determined by three samplings effected in consecutive months (from March to May 2015) of the harvest cycle. Biodegradable film guaranteed an effective mulch along the whole strawberry cycle (9-10 months including the time of drawing up of film). Yields of cv Sabrina on LDPE was 18% higher than those on Mater-Bi<sup>®</sup> while the opposite was detected in cv Fortuna (+10%). The physical-chemical parameters of fruits were not modified by the mulches. The content of the bioactive compounds, instead, resulted, in each time of sampling, significantly higher in fruits picked on Mater-Bi<sup>®</sup> based film.

<p>This study aimed to investigate the effects of grafting tomato on different tobacco rootstocks on quality factors and nicotine content. The commercial variety (Solanum lycopersicum ‘H2274’) (BIOTECH) of the tomato was used as the scion plant, and six different tobacco (Nicotiana tabacum L.) rootstocks were used: Taşova, Tekel, Muş, Samsun, Dişbudak, Hasankeyf cultivars. Cleft grafting method was used in all plants. Yield of non-grafted and grafted plants grown in open-field conditions was calculated, and there was a significant increase in yield in grafted tomatoes compared to non-grafted tomatoes. There was significantly increased lycopene and β-carotene levels (mg kg-1), especially in ‘Tekel’, ‘Taşova’, ‘Samsun’, and ‘Hasankeyf’ tobacco grafts. There was a statistically significant difference between grafted and non-grafted plants according to 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free radical retention capacities and total phenol (TP) values. Evaluation of quality determinants including pH values, titratable acidity values (citric acid %), soluble solid content (SSC)(oBrix) , fruit size ratios, showed that tomatoes grafted with ‘Muş’ tobacco rootstock were of higher quality. There was no significant difference between grafted and non-grafted plants according to nicotine analysis of the tobacco-grafted tomatoes, and due to acceptable ranges of nicotin level on tobacco grafted tomato plants were considered to be suitable for consumption. It could be concluded that grafting practices have significantly positive effects on tomato yield and quality.<br /><br /></p>

Arbuscular mycorrhizal fungi (AMF), which are beneficial soil organisms, have an important role in the uptake of plant nutrients by roots and thus help to healthy plant growth. The aim of this study was to determine the effects of AMF inoculation on the development of water-deficiency applied pepper plants. In this study, Tesla F1 pepper cultivars, Glomus etunicatum inoculated and without Glomus etunicatum, were exposed to four different irrigation regimes (25I, 50I, 75I, 100I). At the end of the experiment these plants were compared in terms of some vegetative and fruit properties. For this purpose, at the end of the trial; shoot length (cm), root length (cm), root spread (cm), number of leaves, leaf width and length (mm), stem diameter (mm), fruit width (mm), fruit length (mm), root and shoot weights (g), fruit pH, total soluble solid content and chlorophyll index were measured. P (phosphorus) and K (potassium) contents of leaves samples taken from plants were determined. As a result, it was determined that 75I irrigation regime gave the best results in terms of both plant growth and fruit properties in all mycorrhizal and non-mycorrhizal plants. It was also concluded that 75% irrigation level is sufficient for plant growth.
