Resting tryosinase was diamagnetic between 1.4 K and 200 K. Redox titration showed that it, but not apotyrosinase, contained a titrable group, E’, = $0.36 volt (pH 7.0), R = 2. Upon denaturation with acid under strictly anaerobic conditions, the EPR-detectable copper increased from less than 5 % of the copper present to about 100%. It is concluded that the active site of the enzyme contains a p...

ABSTRACT Strawberry fruit quality traits can be affected by genotype-environment interactions, which determine the consumer acceptance of fruits. This factorial experiment was based on completely randomised blocks (RCBD) with two planting dates (5 and 20 April) cultivars (‘Albion’, ‘San Andreas’ ‘Portola’) strawberry three replications, some pomological qualitative factors berry were investigat...

the field experiment was conducted to study the effect of soil moisture tension and potassium on growth and quantitative and qualitative characteristics of thomson navel orange on citrumelo rootstock in kotra citrus research station in ten years (1998-2009). the experiment was designed for four replications in randomized complete blocks with factorial treatment structure. the factors consisted ...

Cactus cladodes are consumed by humans in arid and semiarid regions of the world. The use biofertilizers when cultivating cacti can improve physical chemical characteristics soil, as well cladodes’ productivity physical-chemical quality. We evaluated qualities different lengths Opuntia stricta (Haw.) Haw. Cladodes were grown with biofertilizer doses. 3 × 5 factorial design employed corresponded...

The aim of this study was to determine organic acids and individual sugars as well as carotenoids in fruit of Kumquat[Fortunella margarita (Lour.) Swingle] on different rootstocks.  On other hand, the purpose of this study was to identify the rootstock that could produce the highest amount of sugars. The content of individual sugars and organic acids in fruits were determined by HPLC, ...

More than a century of observations has established that climate influences grape berry composition. Accordingly, the projected global climate change is expected to impact on grape berry composition although the magnitude and direction of impact at regional and subregional scales are not fully known. The aim of this study was to assess potential impacts of climate change on levels of berry anth...

Mastitis is an inflammatory reaction of the mammary tissue in response to the introduction and multiplication of pathogens and is characterized by increasing somatic cell count (SCC) in milk. The main objective of present study is to assess the probable associations between somatic cell (SC) levels and calcium and phosphorus and ratio of Ca/P in raw milk. Milk samples were collected from indivi...

The potential of near infrared spectroscopy (NIRS) in the wavelength range of 1000-2500 nm for predicting quality parameters such as total soluble solids (TSS), acidity (TA), firmness, and individual sugars (glucose, fructose, sucrose, and xylose) for two cultivars of apples ("Braeburn" and "Cripps Pink") was studied during the pre- and post-storage periods. Simultaneously, a qualitative invest...

Over 60% Serbian soils are heavy, shallow and acidic, especially in west part of this country. Basically, Serbian fruit production is mainly represented in these conditions which are not favorable for intensive fruit growing. However, repair of these soils is a long and very expensive process. Regarding to this, one of the real ways to overcome this problem faster and cheaper is to grow toleran...
