“…The firmness of blueberries in this study was not affected by hypobaric treatment (Figure 1b), which is consistent with the results of hypobaric treated strawberry fruit reported by Hashmi et al (2013). Moreover, the respiration rate of mangoes was reported to increase with hypobaric treatment (Tovar, Montalvo, Damián, García, & Mata, 2011), whereas that of strawberry and curled lettuce was demonstrated to decrease under hypobaric storage (An, Park, & Dong, 2009). In this study, the respiration rate of blueberries was lower under 0.025 MPa and higher under 0.05 MPa treatments than control, respectively (Figure 1c).…”

This study investigated the effect of hypobaric treatment on the fruit quality, bioactive compound contents, and reactive oxygen species (ROS) metabolism of blueberry. Blueberry fruit cv. bluecrop were stored under hypobaric pressures of 0.025, 0.05, 0.075 and 0.1 MPa (control) at 20°C for 25 and 50 d, respectively. Fruit physiological changes, bioactive compound contents, pro-and anti-oxidant enzyme activities and antioxidant capacities were monitored. Results showed that hypobaric treatment had little influence on decay rate, firmness, respiratory rate, pH and soluble solid content (SSC). However, the contents of bioactive compounds such as anthocyanins, total phenols, and total flavonoids increased significantly, especially at 0.025 MPa. The effect of hypobaric storage on the bioactive compounds of blueberries was through (i) promoting ROS degradation through catalase (CAT), (ii) reducing ROS and bioactive compounds degradation by polyphenol oxidase (PPO) and peroxidase (POD), (iii) increasing the ROS scavenging and antioxidant capacity of blueberries.

ABSTRAKCempedak (Artocarpus champeden), merupakan salah satu jenis tanaman eksotis asli Indonesia. Rasa buahnya sangat manis dan legit, aromanya sangat wangi dan khas. Buah cempedak merupakan buah klimaterik yang tingkat ketuaannya tidak seragam. Penelitian ini bertujuan untuk mendapatkan teknologi pemeraman buah cempedak yang menghasilkan kematangan buah cempedak lebih seragam dan lebih cepat tanpa harus merubah karakter fisik dan kimianya. Rancangan penelitian yang digunakan adalah rancangan acak lengkap (RAL) 1 faktor yang terdiri dari sepuluh (10) perlakuan pemeraman dengan dua ulangan. Perlakuan tersebut meliputi kontrol (tanpa perlakuan), pelukaan, karbit pada beberapa dosis 1, 2, 3, dan 4 g/kg buah (C1,C2, C3 dan C4) dan ethrel pada beberapa dosis (1000, 1500, 2000 dan 2500) ppm. Analisis statistik yang dilakukan meliputi analisis univariate dan multivariate. Hasil penelitian menunjukkan bahwa perlakuan pemeraman dengan karbit dan ethrel dapat mempercepat pematangan buah cempedak lebih cepat 3 hari dibandingkan dengan perlakuan kontrol dan pelukaan. Semakin tinggi dosis karbit dan ethrel nilai TPT dan kadar air cenderung semakin rendah, sebaliknya nilai vitamin C semakin tinggi dengan semakin tingginya dosis pada hari keempat setelah pemeraman. Perlakuan pemeraman dengan dosis karbit 2 dan 3 g/kg mempunyai kemiripan dengan perlakuan pemeraman ethrel 1500 dan 2000 ppm pada karakter total asam, vitamin C, total padatan terlarut dan kadar air setelah 7 hari pemeraman. Analisis univariate (anova) efektif dalam hal memberikan informasi mengenai perlakuan yang terbaik, sedangkan analisis multivariate (manova dan PCA) efektif dalam mengurangi/mereduksi jumlah variabel dan menentukan kemiripan suatu variabel.Kata kunci: Cempedak, Fisikokimia dan Pemeraman, Analisis Univariate, Analisis Multivariate ABSTRACT Cempedak (Artocarpus champeden), is one of the original Indonesian exotic plant species. The fruit tastes very sweet and sticky, very fragrant aroma and distinctive. Cempedak fruit is a fruit that has dissimilar maturity level. This study aimed to obtain cempedak fruit ripening technology that produces cempedak fruit's maturity to be relatively homogeneous and faster without having to change the physical and chemical characteristics. The experimental design used was a completely randomized design (CRD) 1 factor of ten (10) ripening treatment with two replications. The treatment includes a control (no treatment), wounding, carbide at a dose of 1, 2, 3, and 4 g / kg of fruit (C1, C2, C3 and C4) and Ethrel at several doses (1000, 1500, 2000 and 2500) ppm. Statistical analysis was conducted such as univariate and multivariate analyses. The results showed that treatments with calcium carbide and ethrel ripening may accelerate fruit ripening faster 3 days compared to the control treatment and wounding. The higher dose of calcium carbide and ethrel, TPT value and water content tend to be lower, whereas the higher value of vitamin C with the higher dose on the fourth day after ripening. Ripening treatment with doses o...

“…The effect of hot dips in minimizing the postharvest disease incidence is well known. The use of exogenous ethylene for early fruit ripening has also been determined by previous studies carried out by Burg & Burg (1961), Hofman et al (2001), and Tovar et al (2011). Various fungicides have been tested either alone or in combination with other fungicides for minimizing the postharvest diseases .…”

“…It ripens after harvest under storage conditions. After harvest, mature green mangoes in storage produce low amounts of ethylene which helps in ripening and colour development; however, the exposure of mature fruit to exogenous ethylene can trigger this ripening process and give fruit a more uniform yellow colour (Burg & Burg 1961;Hofman et al 2001;Montalvo et al 2007;Tovar et al 2011). Ethylene facilitated ripening of fruit favours its quick marketing which can help reduce postharvest spoilage.…”

“…Montalvo et al (2007) also observed uniform ripening when the mango fruit of cultivar Ataulfo was treated with exogenous ethylene at the rate of 100µL L -1 for 12h. In a recent study carried out by Tovar et al (2011), a vacuum of 34KPa was applied to Ataulfo mangoes before ethylene gas exposure (500, 1000 and 1500 µL L -1 ) for 30 minutes. Exposure to a vacuum did not cause any apparent damage to the fruit but an overall reduction of up to 3 days in the fruit ripening process was observed.…”

Fruit bagging experiments were carried out on Kensington Pride (KP) and R2E2 cultivars of mango to investigate the time of infection of dendritic spot and stem end rot. The fruit were bagged at four different growth stages. The results showed that fruit bagged at golf ball size which remained bagged until harvest had low incidence of dendritic spot and stem end rot.Higher incidence was observed in the fruit which were bagged close to harvest and the unbagged control fruit. It was concluded from the results that pathogens invade the fruit at an early growth stage and fruit protection at this stage of growth can help in minimizing postharvest disease incidence.The effect of conventional and improved orchard practices on the management of anthracnose and stem end rot was also studied. The experiment was carried out in Pakistan.Three districts of Punjab province of Pakistan were selected for the study. The fruit of Chaunsa cultivar of mango were collected from growers" conventional practice blocks and ASLP (Agriculture Sector Linkages Program) improved practice blocks. In the conventional practice blocks, there was irregular application of foliar and pesticides sprays, non-consistent use of fertilizers with a minimum use of cultural practices such as irrigation, pruning, weeding and soil nutrition analysis, use of recommended foliar sprays of fungicides for disease management at different fruit growth stages, pest management and nutrient management by annual application of NPK. Whereas, the improved practice blocks were maintained by cultural practices. A low incidence of anthracnose and stem end rot was observed in the fruit which was collected from the ASLP improved practice blocks as iii compared to the incidence observed in the fruit collected from the conventional practices blocks.Postharvest application of exogenous ethylene on mature fruit to induce uniform skin colour and ripening and hot fungicide dips to minimize postharvest disease incidence are common practices used by Australian mango growers. Early fruit ripening facilitated by exogenous ethylene is helpful in early fruit marketability, but it can result in higher disease incidence in case of prolonged fruit storage or higher fruit storage temperature. The effect of exogenous ethylene and hot fungicide dip with fludioxonil was investigated when both treatments were applied on the fruit alone and in combination with each other. The results showed that the application of exogenous ethylene alone caused higher incidence of dendritic spot and stem end rot when the fruit received frequent rainfall during the growing season. This higher incidence of both dendritic spot and stem end rot could also be because of accelerated fruit ripening and decline in fruit resistance. But, when low or no rainfall was received during the season, a low incidence of dendritic spot and stem end rot was observed when the exogenous ethylene was applied on the mature fruit. Fruit hot-dipped in the fungicide fludioxonil followed by the exogenous ethylene had zero to minimum inciden...
