As a part of the study to explore the possible strategy for enhancing the shelf life of mango fruits, we investigated the changes in biochemical parameters and activities of ripening associated enzymes of Ashwina hybrid mangoes at 4-day regular intervals during storage at -10°C, 4°C, and 30 ± 1°C. Titratable acidity, vitamin C, starch content, and reducing sugar were higher at unripe state and ...

In the present study, effects of NaCl concentrations (0, 20, 40 and 80 mM) were investigated in Ceratophyllum demersum. Macronutrients N, P and K and micronutrients Zn and Cu were significantly decreased by NaCl salinity. In general, however, Fe and Mn accumulation showed to increase. As a results, NaCl toxicity disturbed the uptake and translocation of macro and micronutrients in the macrophyt...

Humic acid (HA) is a kind of organic substance that has shown good effects in regard to promoting crop growth. In the current study, influences three kinds fertilizers mainly containing humic/fulvic acids, including water-soluble fertilizer humic (WHA), fulvic potassium (FAP), and distillate (FAD), on qualities ‘Eureka’ lemon fruits were investigated systematically at their different harvest ti...

Four different soluble fibres were evaluated as sugar replacers in short dough biscuits: two resistant dextrins (Nutriose® FM06 and Promitor® SGF 70R) inulin-derived (Orafti® HSI Fibruline™ Instant). The degree of polymerisation the was analysed, viscoelastic properties assessed. Weight loss during baking, dimensions, textural properties, surface colour sensory profile evaluated. Higher (e.g. F...

The signals controlling the abundance of transcripts up-regulated (pTIP27, pTIP31, and pTIP32) or down-regulated (pTIP20 and pTIP21) after harvest in asparagus (Asparagus officinalis L.) spears were examined. pTIP27 and pTIP31 are known to encode asparagine synthetase (AS) and a beta-galactosidase (beta-gal) homolog, respectively. The nucleotide sequences of pTIP20, pTIP21, and pTIP32 were dete...

FT-NIR was evaluated as a method to analyze 16 components (analytes) in tobacco. For each component, spectra of 578 to 785 samples were utilized respectively as calibration samples to develop the calibration model. For all calibrations, the raw spectra were pretreated as first derivative, and Partial Least Square (PLS) was used as the calibration algorithm. About 50 randomly selected validation...

Soluble sugars, especially sucrose, glucose, and fructose, play an obviously central role in plant structure and metabolism at the cellular and whole-organism levels. They are involved in the responses to a number of stresses, and they act as nutrient and metabolite signalling molecules that activate specific or hormone-crosstalk transduction pathways, thus resulting in important modifications ...

Two Chinese jujube (Zizyphus jujuba) cultivars ('Huanghua' and 'Zhanhua') at unripe and ripe stages were investigated. During ripening, the weight, pH, hardness, and chewiness of both cultivars decreased while titratable acidity, total soluble solid content, and pectin contents increased. More than 75% pectins of the fruits were water-soluble pectin (WSP). Pectins shared the common major compos...

in this study the effects of plant growth regulators including; ga3 (0 and 50 mg/l) and ethephon (0 and 500 mg/l) were studied on the quality properties of two grape cultivars (perlette and yaghuti). at the harvest time, some physicochemical characteristics such as fruit cluster weight, fruit diameter, length, volume and l/d ratio, flesh firmness, fresh weight, ta, ph, tss and fruit color were ...
