drought stress is the most important factor that reduces yield in crops including chickpea and causes some changes in seed composition. this study was performed in order to evaluate the effects of drought stress and starter nitrogen fertilizer on four cultivars of chickpea. experiment was performed in a split-factorial using randomized complete block design with three replications. drought stre...

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...

Quality characteristics of Korean commercial apple wine, Moru wine, red wine, white wine, and raspberry wine were compared in this study. The aim of this study is to improve the quality of fruit wines, based on physicochemical characteristics, fermentation quality, correlation between soluble solid and sugar content, and a relationship between electrical conductivity and other analyzed paramete...

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...

to clarify the underlying physiological mechanism of gibberellic acid (ga) in cold tolerance, the effects of exogenous ga3 on malondialdehyde (mda), osmoregulation substances and endogenous hormones levels in the tiller nodes of two wheat cultivars, namely, dongnongdongmai 1 (a cold insensitive cultivar) and jimai 22 (a cold sensitive cultivar), were investigated at three periods of cold winter...

This paper reports on the use of Artificial Neural Networks (ANN) and Partial Least Squareregression (PLS) combined with NIR spectroscopy (900-1700 nm) to design calibration models for thedetermination of sugar content in sugar beet. In this study a total of 80 samples were used as the calibration set,whereas 40 samples were used for prediction. Three pre-processing methods, including Multiplic...

silicon is known to ameliorate the deleterious effects of drought on plant growth. we evaluated growth of wheat (triticum aestivum l. cv. chamran) under water-deficit stress induced by polyethylene glycol as affected by si application. in this article, the effects of si (as potassium silicate) on some parameters related to growth, chlorophyll concentration relative water content (rwc), electrol...

objective: salt stress is a world-wide problem and soil salinity is common in arid and semi-arid regions. this study was undertaken to investigate salt tolerance in salsola orientalis in laboratory and natural conditions and recognize the mechanisms that allow it to tolerate these conditions. methods: this study had two parts of greenhouse and natural habitats. the treatment solutions for salin...

The solvent partitioned purified fractions of the hydro-acetone root bark extract of the African breadfruit (Treculia africana Decne) were evaluated for hypoglycemic activities in normal and diabetic albino rats. Fasting blood glucose levels were estimated by the use of a glucometer at pre-determined intervals after oral administration of the test extracts/fractions. Results revealed that the t...

It has been suggested that respiratory stress is involved in the mechanism underlying the dormancy-breaking effect of hydrogen cyanamide (H2CN2) and sodium azide in grapevine buds; indeed, reductions in oxygen levels (hypoxia) and inhibitors of respiration promote bud-break in grapevines. In this study, we showed that, hypoxia increased starch hydrolysis soluble sugar consumption and up-regulat...
