Heavy metals in soil, water and air is a great concern. Toxic heavy metals ultimately affect plant, Animals, and through food chain directly influence human life. In present study, the effect of heavy metals (Cu, Zn), Nfertilizers and EDTA on growth and biomass of cannibus sativa plant was evaluated. The Cu and Zn phytoextraction potential of Cannabis sativa plant under various treatments of N-...

The aim of the present study was to dissect the genetic inheritance and interplay of root, shoot and heading attributes for a better understanding of these traits in crop production. For this, we utilized quantitative trait loci (QTL) and candidate gene analysis approach using a second filial (F2) population originated from a cross between spring cultivar Cheri and wild barley accession ICB1811...

The genetic control of propagation effects and the impact of stock-plant age and source was examined in 9 month-old Pinus radiata cuttings. The cuttings investigated were propagated from stock-plants aged between 2 and 5 years, and microcuttings propagated from 12 week old stock-plants. The design included 20 families, with seven clones per family and an average of seven ramets per clone. Five ...

Cultivated soybean (Glycine max L.) cv. Dunbar (PI 552538) and wild G. soja (PI 326582A) exhibited significant differences in root architecture and root-related traits. In this study, phenotypic variability for root traits among 251 BC2F5 backcross inbred lines (BILs) developed from the cross Dunbar/PI 326582A were identified. The root systems of the parents and BILs were evaluated in controlle...

The question of whether abscisic acid (ABA) acts as an inhibitor or promoter of shoot growth in plants growing in drying soil is examined, drawing on current understanding of the role of ABA in root growth maintenance. Particular consideration is given to studies of endogenous ABA deficiency, which have shown that an important role of ABA is to limit ethylene production, and that this interacti...

In order to explore the mechanism of delayed and uneven germination in sharp tooth oak (Quercus aliena var. acuteserrata) (STO), mechanical scarification techniques were used to study STO root and shoot germination and growth. The techniques used were: removing cup scar (RS), removing the pericarp (RP), and cutting off 1/2 (HC) and 2/3 (TC) cotyledons. Germination percentage and root and shoot ...

in a greenhouse experiment, the effects of waterlogging, sewage sludge and manure on the uptake and concentrations of p, k, ca, mg and na in root and shoot of sunflower (helianthus annuus l.) were investigated. a factorial experiment based on completely randomized design with three replications including duration of waterlogging at five levels (0, 2, 4, 8, 22 days), source of organic fertilizer...

Root architecture is an important regulator of nitrogen (N) acquisition. Existing methods to phenotype the root architecture of cereal crops are generally limited to seedlings or to the outer roots of mature root crowns. The functional integration of root phenes is poorly understood. In this study, intensive phenotyping of mature root crowns of maize was conducted to discover phenes and phene m...

Fungus-plant associations are of the most important mutually beneficial relationships in the ecosystem which positive effects on growth, physiology and ecology of different plants have been already demonstrated. Biological methods such as employing symbiotic (arbuscular mycorrhizal) fungi to roots of plants are considered as potential effective ways of reducing the stressful effects of soil con...

Purpose Soil contamination by multiple organic and inorganic contaminants is common but its remediation by hyperaccumulator plants is rarely reported. The growth of a cadmium (Cd) hyperaccumulator Sedum alfredii and removal of contaminants from Cd and polycyclic aromatic hydrocarbons (PAHs) co-contaminated soil were reported in this study. Materials and methods Soil slightly contaminated by Cd ...
