In order to better understand how to prevent enzymatic greenning, it is important to understand  kinetic properties of polyphenol oxidase.  we investigated the effect of SDS on the rate of catechol oxidation by small cherry tomato partial purified PPO. PPO activity increased with increasing SDS concentration. The most effective concentration of SDS was 0.8, 1 and 1.25 mM in according to pH and ...

Cherry tomato cultivation in protected environments ensures production the off-season, reaching yields up to 100 t ha-1 with 150 days of cultivation. Fertilization organic composts can influence components cherry tomato. From this perspective, study aimed evaluate different doses and composts, based on their nitrogen contents, The experiment was conducted municipality Boa Vista - RR, at Agrotec...

This article is divided into three parts. The first part, the most important one, deals with spectroscopic methods. Different regions of the electromagnetic spectrum are useful for fruit quality characterisation, in particular the visible and near-infrared regions. Concerning the visible one, studies have been carried out on apple, apricot, cherry, mango, peach, red table grape and tomato, when...

BACKGROUND Tomato fruits contain a high level of antioxidants such as vitamin C, polyphenols (including flavonoids), and carotenoids (such as lycopene and β-carotene). Some studies have shown the higher level of bioactive compounds in organically produced tomato fruits compared to conventional ones, but not all studies were consistent in this respect. The levels of carotenoids and phenolics are...

ABSTRACT The crown gall pathosystem was used to evaluate a model that describes the dose-response relationship between biological control agents and plant pathogens. The model predicts that this relationship can become asymptotic, such that increased antagonist doses cannot compensate for deficiencies in disease suppression. Wounded roots of tomato (Lycopersicon esculentum) and cherry (Prunus m...

The study titled “Evaluation of varieties and fertilizers doses on growth, yield quality cherry tomato grown under protected condition” was conducted in 2021-2022 season at the Department Horticulture, Naini Agricultural Institute, Sam Higginbottom University Agriculture Technology Sciences, Prayagraj, Uttar Pradesh during Rabi-2021-22 with objective to determine effect fertilizer application m...
