| | Ethylene FAQ's |
 | | While ethylene is invaluable due to its ability to initiate the ripening process in several fruits, it can also be very harmful to many fruits, vegetables, flowers, and plants by accelerating the aging process and decreasing the product quality and shelf life. | | | Ethylene can promote ripening in tomatoes, bananas, citrus, pineapples, dates, persimmons, pears, apples, melons, mangos, avocados, papayas and jujubes - a clear indication that the action of ethylene is general and widespread amongst a number of fruits. | | | It affects the growth, development, ripening, and senescence (aging) of all plants. |

| | Ripening Tomatoes With Ethylene |
| | Decreasing the time for ripening initiation by only one day would represent substantial reduction of energy requirement, as ripening room construction and operation are high energy consumers. | | | Ethylene is naturally produced by a number of vegetable crops. | | | This amount of air (41.7 CFM) can easily be provided by a small blower type fan mounted over a two inch diameter opening through the wall into the ripening room. |

| | GEO-PIE Project: Delayed fruit ripening |
| | Delaying the ripening process in fruit is of interest to producers because it allows more time for shipment of fruit from the farmer's fields to the grocer's shelf, and increases the shelf life of the fruit for consumers. | | | Fruit that are genetically engineered to have delayed ripening can be left to mature on the plant longer, will have longer shelf-life in shipping, and may last longer for consumers. | | | Because ethylene is the main trigger for fruit ripening, several genetic engineering strategies involve the reduction or prevention of ethylene production. |

| | Fruit Ripening |
| | In this way then, the ripening process is used for a second function in the plant...to make the fruit drop from the tree so an animal can pick it up and carry it off to disperse seeds. | | | The fruit is full size but it is green and immature...events must now happen to cause it to ripen so that it is attractive and rewarding for an animal to carry it off...dispersing the seeds. | | | The way fruits ripen is that there is commonly a ripening signal...a burst of ethylene production. |

| | Ostwald ripening |
| | Ostwald ripening means big crystals growing at the expense of little crystals. | | | One reason is that the nucleation of many small crystals reduces the amount of supersaturation and thus, the thermodynamically favored large crystals never get a chance to appear. | | | The ones in the middle or the ones you are packing in on top, trying to get them to fit?) Large crystals, with their greater volume to surface area ratio, represent a lower energy state. |

| | Agricultural Research: Sweet success in Texas - biochemical aspects of the ripening of sugarcane |
| | Evidently, ripening in sugarcane was not caused by unmetabolized sugar going to mature stems for storage. | | | "We found that ripening was associated with an increase only in the percentage of stem sugar that was sucrose," says Lingle, "not an increase in the sugar itself." | | | More sugar would then accumulate in the mature, ripening stem since it wasn't needed elsewhere. |

| | Jiwan Paul Palta of the University of Wisconsin and an original founder of Nutra- Park, was conducting research with the goal of reducing the impact of early frost on Wisconsin’s cranberry crop. | | | Conventional wisdom states that fruit ripens in response to an increase in ethylene production resulting in an increase in respiration. | | | It also has the ability to slow senescence, allowing fruits, vegetables and cut flowers to stay fresher and last longer. |

| | Control of Premature Ripening of Bartlett Pears, FS 241 |
| | Orchards where the entire soil surface is shaded by the trees may absorb less heat during the day and be colder at night than orchards where the sun warms the soil during the day. | | | In an advanced stage of the disorder, a greatly accelerated rate of maturation and ripening causes the fruit to drop before normal harvest. | | | A dose of NAA as low as 37 ppm within 6 days before harvest could significantly increase premature ripening. |

| | Ripening - Wikipedia, the free encyclopedia |
| | If too few seeds in a multiseeded fruit are formed (by fertilization of the ovules), the flesh of the fruit may not develop in some areas, and ripening will be retarded or prevented. | | | Fruit growers increasingly monitong and/or mature fruit and adjust pollination management accordingly. | | | An important plant hormone involved with ripening is the chemical ethylene. |

| | THE ROLE OF ETHYLENE IN FRUIT RIPENING |
| | Ethylene is a plant hormone regulating fruit ripening by coordinating the expression of genes that are responsible for a variety of processes, including a rise in respiration, autocatalytic ethylene production and changes in color, texture, aroma and flavor. | | | Both enzymes are limiting in preclimacteric fruits but are greatly induced during the ripening. | | | Experiments using ethylene inhibitors, pulse ethylene treatment and antisense transgenic fruits demonstrated that ethylene synthesis plays a key role in regulating fruit maturation and ripening. |
