Plant hormones are specialized chemical substances produced by plants. They are the main internal factors controlling growth and development. Hormones are produced in one part of a plant and transported to others, where they are effective in very small amounts. Depending on the target tissue, a given hormone may have different effects. Plant hormones play an integral role in controlling the growth and development of plants. A plant hormone is generally described as an organic compound synthesized

Effects of Pre-harvest Factors Pre-harvest factors can influence the final quality of a product including papaya. Post-harvest product qualities develop during growing of the product and are maintained and not improved by post-harvest technologies (Hewett, 2006). Depending on the cultivar, maturity, climate, soil type and fertility, the nutritional composition of a fruit at harvest can vary widely. For example Banana and papayas increase in carotenoid content with maturation and ripeness, but the

Back in the 19th century bananas were not widely known. In fact, the western world hardly consumed the fruit, because of its exotic origin. The cultivation of banana is not easy. Bananas are one of the most highly perishable products that also need specific weather conditions in order to thrive. Indeed, bananas are only cropped in tropical regions, where temperature never falls under 13-14 degrees Celsius with high percentage of humidity and well-drained soil. Moreover, countries with tropical climate

4. Discussion 4.1 Chilling injury index We previously reported that a 15-d period of cold storage at 5 °C was enough to develop CI symptoms in mature-green tomato fruit cv. Imperial (Vega-García et al., 2010). In agreement with those results, in the present study we observed CI symptoms after the fruit was stored 10 d at 5 °C, but they were more intense after 15 d of cold storage (Fig. 2). As expected, tomato fruit stored at 12 °C did not show CI symptoms (Malacrida et al., 2006; Bojórquez-Gálvez

All animals are susceptible to ethylene glycol toxicity, but it is most common in dogs and cats. Most intoxication is associated with ingestion of antifreeze, which is typically 95% ethylene glycol. Cats are susceptible to ethylene glycol toxicity with a minimum toxic dose of just 1.4 ml/kg. Exposure occurs when cats drink the toxin which has a sweet taste or when anti-freeze is added to water sources or their coats/feet are contaminated with the chemical. Some of the initial clinical signs or symptoms

When reading Banana by Dan Koeppel I felt that by reading this book I’d learn more about the banana and why we love it so much. When I started reading, I began to understand that there are more than one species of banana and that this little fruit migrated just like all humans did across the world. Koeppel states that the apple from the garden of Eden wasn’t really an apple at but a banana, he goes into reasons why it absolutely would be a banana and not an apple. He also travels to different

Shale Gas to Ammonium and Ethylene Nikita Cardenas, Lucas Freiberg, James Watkins, Heitor Almeida Rogerio RA2 Main Goals: We are interested in using our shale gas stream, which we currently sell as heating fuel, to create another product of value. We are considering taking the shale gas and producing anhydrous ammonia, urea, ammonia sulfate, and ethylene. The main goal is to make a greater profit from our shale gas by selling it as more valuable products rather than

The Toxicology of Cosmetic Chemicals; layman’s land is filled with easy-to-digest myth. SOCIETAL CONCERN; Disconnect between scientific knowledge and general public acceptance The ability to effectively communicate the safeties and dangers of chemicals between scientific professionals and the general population has been and continues to be an ongoing concern for both sides. Often, this difficult process of ensuring public safety and confidence in chemical innovation has had a certain void filled

Ethylene glycol -Overview Ethylene Glycol is a clear, odourless liquid with a syrup like consistency and a sweet taste. It has low vapour pressure and it is combustible. Ethylene glycol may also be called mono ethyl glycol or ethane 1,2-diol. Ethylene glycol is produced commercially on a large scale and commonly used as a de-icer and antifreeze due to its solvent properties. It is used in industrial compound due to its high boiling point and low freezing point. Ethylene glycol is used in many consumer
