Foxtail millet (FM) [Setaria italica (L.) Beauv.] is a grain and forage crop well adapted to nutrient-poor soils. To date little is known how FM adapts to low nitrogen (LN) at the morphological, physiological, and molecular levels. Using the FM variety Yugu1, we found that LN led to lower chlorophyll contents and N concentrations, and higher root/shoot and C/N ratios and N utilization efficienc...

drought is one of the important environmental stresses that reduce the crop growth. oxidative stress is a secondary stress due to drought and other abiotic stresses. in order to study the effect of exogenous application of hydrogen peroxide on drought tolerance of glob amaranth (gomphrena globosa l.), an experiment was conducted in greenhouse conditions. this study was designed as factorial bas...

To demonstrate the combined toxicity of cadmium (Cd) and arsenate (As) to early developmental stages of six wheat varieties, young seedlings were exposed to solutions containing both contaminants and seed germination frequency and seedling biomass, root length and shoot height, Cd and As uptake, amylase activity, superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), soluble protein and ...

The present study evaluated the effects of glyphosate on Pisum sativum germination as well as its effect on the physiology and biochemistry of germinated seedlings. Different physico-chemical biomarkers, viz., chlorophyll, root and shoot length, total protein and soluble sugar, along with sodium and potassium concentration, were investigated in germinated seedlings at different glyphosate conce...

late-season drought is the major constraint reducing the productivity of chickpea. this experiment was carried out to study response of root and shoot characteristics in 12 chickpea genotypes to drought stress. two-drought stress levels (-3 and -6 bar) induced by peg 6000 and control in hydroponic condition at green house was performed. leaf relative water content (rwc), plant height, number of...

BACKGROUND AND AIMS The objective of this study was to test whether the mean values of several root morphological variables were related to the ability to develop root-borne shoots and/or shoot-borne roots in a wide range of vascular plants. METHODS A comparative study was carried out on the 123 most common plant species from eroded lands in north-east Spain. After careful excavations in the ...

In the present study, small segments of cotyledon, apical bud, hypocotyl, and root of 10-day-old seedlings were isolated and transferred to Murashige and Skoog (MS) base medium with different treatments of phytohormones. Two media were used for apical bud culture: MS with indole-3-acetic acid (IAA) and kinetin (Kin) (1 mg/l) and the other medium, MS with double vitamin of MS and 6-benzylaminopu...

● Background and aims. The objective of this study was to test whether the mean values of several root morphological variables were related to the ability to develop root-borne shoots and/or shoot-borne roots in a wide range of vascular plants. ● Methods. A comparative study was carried out on the 123 most common plant species from eroded lands in NE Spain. After careful excavations in the fiel...
