The study was undertaken to envisage the effect of growth regulators on preharvest fruit drop and quality of Kinnow mandrin (Citrus reticulata Blanco). Various concentration of 2, 4-D, GA3 and NAA were applied during the last week of November, 2005 to check the impact of various treatments on preharvest fruit drop, yield and fruit quality. Exogenous application of growth regulators significantl...

This investigation was undertaken to ascertain the effect of simulated acid rain (SAR) on growth, yield and physiological parameters of tomato. SAR exposure (pH 3.0 and 4.0) caused white-to-tan spots on the abaxial and adaxial surface of tomato leaves. SAR exposure at pH 3.0 and 4.0 significantly suppressed pigment synthesis, shoot and root dry weights and yield of tomato. The effects were more...

In this work, we propose the reuse of apple pomace as a substrate for fungal chitosan production by liquid cultivation of Gongronella butleri CCT4274. Different concentrations of reducing sugars and sodium nitrate were added to the aqueous extract of apple pomace and the best result was obtained with 40 g/L of reducing sugars and 2.5 g/L of sodium nitrate. The results indicate the possibility o...

Abstrac: This study was carried out to investigate the effect sodium benzoate on apple and apricot blend juice. The samples were; apple juice (T ), apricot juice (T ), 75% apple and 25% apricot juice (T ), 50% apple and 50% 1 2 3 apricot (T ), 25% apple and 75% apricot juice (T ). From (T ) to (T ) above concentrations were repeated with 4 5 6 10 0.01% sodium benzoate as preservative. The sampl...

It has been widely reported in literature that brassinosteroids play a pivotal role in stress mitigation in plants. The present study was undertaken to assess the effect of 24-epibrasssinolide (24-EpiBR) on the growth, endogenous levels of total sugars, reducing sugars and plant growth regulators (PGRs) such as jasmonic acid and polyamines (PAs) like spermine, spermidine, putrescine and cadaver...

This review aims to provide an overview of current knowledge on stabilization of proteins by sugars in the solid state in relation to stress conditions commonly encountered during drying and storage. First protein degradation mechanisms in the solid state (i.e. physical and chemical degradation routes) and traditional theories regarding protein stabilization (vitrification and water replacement...

Benzyne was developed as a reducing agent in the key step of converting amino sugars and ketoses into deoxy sugars, which occur widely in natural products. Many deoxy sugars exhibit antibiotic and anticancer activities, and furthermore, they play essential biological roles. By treatment with CS2 and then Ac2O, amino sugars and ketoses were converted into the corresponding 1,3-thiazolidine-2-thi...
