The postharvest vase life of cut roses was studied to determine the effects of various physiological factors that influence the vase life of cut flower. Cut roses were obtained from commercial area of Siliguri. To assess the effect of preservatives on the postharvest life of rose, cut flowers were treated with following preservative solutions: fixed amount of citric acid (CA) (300 mg/ml) and 8-...

Postharvest loss of mango often occurs due to the short harvesting period. An experiment was conducted determine impact paclobutrazol (PBZ) and flower bud pruning (FBP) on regulating flowering, fruiting time fruit quality ‘Amrapali’ mango. Different doses PBZ at 0.5, 1.0, 1.5, 2.0 g per meter canopy diameter water application along with FBP or without were used, as well (control). The caused ea...

This study investigated the effects of 4 aeration levels (varied by injection of air to the soil through subsurface irrigation lines) at two subsurface irrigation line depths (15 and 40 cm) on plant growth, yield and nutritional quality of greenhouse tomato. In all experiments, fruit number, width and length, yield, vitamin C, lycopene and sugar/acid ratio of tomato markedly increased in respon...

in this research, the effect of air pollution on proline concentration, soluble sugar, anatomical and morphological features was studied in two plant species malva parviflora and hordeum glaucum in 2009. the area of the stand steel factory of khuzestan was considered as the polluted site and shush region was considered as the control site, and sampling was carried out from the two sites, accide...

In this research, 5 different pomegranate jams were produced with the addition of anthocyanin-based extract obtained from black mulberry and rose hips by classical ultrasonic extraction methods without extracts (control). The are stored at room temperature (20±2 ℃) for 60 days, ensuring that storage is 0., 20., 40. 60. color, total dry matter, water soluble pH, titration acidity, reduced sugar,...

The microwave enhanced advanced oxidation process (MW/H2O2-AOP) aided with dilute sulfuric acid was applied in a two-stage treatment of dairy manure for nutrient release, solids reduction, and reducing sugar production. A much higher hydrogen peroxide dosage (1.2 g H2O2/g TS) was used in Stage 2 than that in Stage 1 (0.38 g H2O2/g TS). Most of the reducing sugar was produced in Stage 1, and onl...

Soluble sugar is an important index to determine the quality of jujube, and also factor influence taste jujube. The acquisition soluble content jujube mainly relies on manual chemical measurement which time-consuming labor-intensive. In this study, feasibility multispectral imaging combined with deep learning for rapid nondestructive testing fruit internal was analyzed. Support vector machine r...

We aimed to establish standards for tobacco Valor de Cultivo e Uso (VCU) in Brazil. We obtained information regarding the size and design of plots of two varietal groups of tobacco (Virginia and Burley). Ten inbred lines of each varietal group were evaluated in a randomized complete block design with four replications. The plot contained 42 plants with six rows of seven columns each. For each e...

A split plot 3 by 3 experiment was designed to investigate the relationships among production of primary metabolites (soluble sugar and starch), secondary metabolites (total flavonoids, TF; total phenolics, TP), phenylalanine lyase (PAL) activity (EC 4.3.1.5), protein and antioxidant activity (FRAP) of three progenies of oil palm seedlings, namely Deli AVROS, Deli Yangambi and Deli URT, under t...

Osmotic adjustment was studied in cultured cells of tomato (Lycopersicon esculentum Mill cv VFNT-Cherry) adapted to different levels of external water potential ranging from -4 bar to -28 bar. The intracellular concentrations of reducing sugars, total free amino acids, proline, malate, citrate, quaternary ammonium compounds, K(+), NO(3) (-), Na(+), and Cl(-) increased with decreasing external w...
