What is the effect of ethylene to fruit weight?

The impact of ethylene on fruit weight varies depending on the fruit type and concentration of ethylene applied. Research on apricots showed that the removal of ethylene using potassium permanganate and Zeolite-based filters led to reduced weight loss in the fruits, enhancing their shelf life and marketing quality. In summer squash, exposure to exogenous ethylene did not stimulate weight loss but induced physiological changes and external appearance alterations. Aleatico wine grapes treated with ethylene exhibited higher weight loss during dehydration, possibly due to increased enzyme activities, yet showed elevated polyphenol and anthocyanin content. Plum fruits exposed to ethylene experienced increased weight loss, with differences observed between ethylene-treated fruits and controls, suggesting a significant influence of ethylene on fruit weight.How gram coloration color the gram negatif bacteri ?

Gram staining differentiates bacteria into gram-negative and gram-positive based on cell wall composition. Gram-negative bacteria appear pink after staining due to their higher lipid content, while gram-positive bacteria retain the purple color as they have higher peptidoglycan content.
