“…Los frutos no presurizados presentaron la VPE caracterı´stica del mango 'Ataulfo', el etileno se detecto´a partir del dı´a 4 y de ahı´se elevo´hasta alcanzar un valor promedio de VPE de 2,84 mL/kg/h de etileno en el dı´a 14, lo que coincide con Montalvo et al (2007). La VPE fue afectada significativamente (p 0,01) por el nivel de presio´n, el tiempo de presurizacio´n y su interaccio´n.…”

“…Acetylene is generated from calcium carbide by the addition of water or by contact with moisture in air and act on fruits causing them to ripen in a similar manner to ethylene. The benefits of ethylene induced ripening were recently reported for "Ataulfo" Mangoes (Montalvo et al, 2007). The rate of ripening in mangoes can accelerated by treating the fruit with ethylene (Kader and Mitcham, 2008).…”

“…The role of ethylene in the regulation of fruit ripening in many kinds of fruits was investigated. Montalvo et al (2007) concluded that ripening reactions controlled by ethylene can be increased by exposure of the fruit to an atmosphere containing exogenous ethylene in order to produce homogeneous external colour. Ethrel (2, chloroethyl phosphonic acid) is one of the ethylene releasing substances, known mainly for its ability to induce fruit ripening.…”

An experiment was done to assess the effect of various post harvest treatments of ethrel on ripening behaviour and post harvest quality of mango cv. Amrapali (Mangifera indica L.) during storage at Punjab Agricultural University, Regional Research Station, Gurdaspur during the years 2013-14 and 2014-15. The experiment was planned under completely randomized design (CRD) with three replications. The treatment units was six fruits per replication. Total five treatments and control were applied. The objective of this work was to evaluate the effects of various concentrations of ethrel (500 ppm, 750 ppm, 1000 ppm,1250 ppm, 1500 ppm and control ) on shelf life of mango fruits when stored under ambient conditions. The treated fruits were assessed for physiological changes fruit colour, flavour/aroma, organoleptic taste, marketability, ripening, specific gravity, moisture loss, decay, physiological loss in weight (PLW), total soluble solids (TSS), acidity and sugars. The observations were recorded at 5, 8 and 11 days after storage. At 11 th day of storage these mangoes exhibited deep yellow fruit colour with excellent flavour, organoleptic taste and highly acceptable marketability at 1000 ppm ethrel treatment as compared to other ethrel doses. Fruit ripening (100%), specific gravity (0.84), TSS(23°Brix) and sugars(20.65%) were highest in the fruits treated with 1000ppm ethrel as compared to rest of treatments at 11 th day of storage. Lowest moisture loss (8.5%), decay (1%), PLW(12.50%) and acidity(0.12%) were observed in the fruits treated with 1000ppm of ethrel as compared to rest of treatments at 11 th day of storage. The beneficial effect of the present study is to overcome the problem of uneven and late ripening of Amrapali mango by postharvest treatment of ethrel at 1000 ppm at their mature green stage to develop typical fruit flavour with excellent fruit quality.

“…The delayed ripening was also observed in peaches and apple by Saftner et al (2003) and when the fruit was subjected to 1-methycyclopropene (1-MCP). 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.…”

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...
