A seedless growth of zinc oxide (ZnO) structures on multilayer (ML) graphene by electrochemical deposition without any pre-deposited ZnO seed layer or metal catalyst was studied. A high density of a mixture of vertically aligned/non-aligned ZnO rods and flower-shaped structures was obtained. ML graphene seems to generate the formation of flower-shaped structures due to the stacking boundaries. ...

Geometry changes, especially surface expansion, accompanying flower primordium formation are investigated at the reproductive shoot apex of Arabidopsis with the aid of a non-invasive replica method and a 3-D reconstruction algorithm. The observed changes are characteristic enough to differentiate the early development of flower primordium in Arabidopsis into distinct stages. Primordium formatio...

The present study investigates the qualitative and quantitative analysis of the major bioactive constituents of medicinally important plant Taraxacum officinale in its aqueous and methanol extract of root, stem and flower. Saponins, flavonoids, alkaloids, phenols were highly concentrated in the stem, root and flower, with the higher concentration of flavonoids in the flower extracts. Phenols an...

The capacity to form flower buds in thin-layer explants was studied in flowering plants of several species, cultivars, and lines of Nicotiana differing in their response to photoperiod. This capacity was found in all biotypes examined and could extend into sepals and corolla. It varied greatly, depending on genotype, source tissue and its developmental stage, and composition of the culture medi...

The influence of scoring during the flower induction phase was investigated. Pear trees, Pyrus communis L. cv. Doyenne du Comice, Forelle and Rosemarie were used in the study, conducted in the Western Cape, South Africa. The yield of ‘Doyenne du Comice’ increased by 38% in scored trees compared to the control. The increase in yield was due to 50% more fruits on the scored trees than on the cont...

This study was carried out to determine the nutritive value of sun flower meal treated and untreated with 0.5% urea and microwave using nylon bags technique in Gizel sheep. Two fistulaed Gizel sheep with average BW 45±2 kg were used in a complete randomized design. The treatments were as following: A: sun flower, B: sun flower treated with 0.5% urea, C: sun flower treated with microwave. The ru...

Objective: To explore the effect of altitude and latitude on breeding of Amomum tsaoko Crevost et Lemaire, a flexistylous ginger, which fruit is used as common materia medica and a food condiment. Methods: The 7 populations were selected randomly from the three floristic zones of Yunnan. Adult plants and infructescences were chosen randomly to gain flower number and fructification percentage pe...

Pollen pistil interaction studies were carried out in six sunnhemp genotypes. viability percentage of the genotypes ranged from 0.0 to 93.5% and pollen germination 84.0% at four different floral stages starting bud opening a flower. The viable grains present later three flower for globose type anthers, while two heart shaped anthers. Stigma receptivity was high very during S3 S4 stages. Artific...

CdS crystallites with rod- and flower-like architectures were synthesized using a facile hydrothermal growth method. The hexagonal crystal structure of CdS dominated the growth mechanisms of the rod- and flower-like crystallites under specific growth conditions, as indicated by structural analyses. The flower-like CdS crystallites had a higher crystal defect density and lower optical band gap v...
