Asexual propagation through cuttings is an appropriate method used for most ornamental plants. Success in increasing the percentage of rooting, reducing root emergence and increasing proliferation efficiency depends on several factors like plant growth regulators, especially auxins. Rooting of Forsythia × intermedia is difficult and requires specific hormonal treatments and proper cultivation b...
There is no functional annotation for the majority of the several hundreds of receptor-like kinases in plants. A direct way of inferring the function of these proteins is to study the phenotype that results from loss of function mutants such as T-DNA mutant lines. In this research a function (phenotype) to At2g37050 gene that encodes a receptor like kinase in Arabidopsis T-DNA line was...
Ficus benjamina L. is indoor plant in temperate areas that is a tree species belongs to Moraceae family. Propagation of this plant is down by vegetative method. This study was conducted to evaluate the effect of IBA concentration and time of taking cutting on propagation of Ficus benjamina via stenting technique in Gorgan University of Agricultural Sciences and Natural Resources, in 2012. Treat...
To evaluate the allelopathic potential effects of giradol (Chrozophora tinctoria L.) organs on seed germination and seedling growth characteristics of watermelon (Citrullus lanatus L.), two experiments were carried out separately as a factorial in a complete randomized design with 4 replications; this study was carried out at Research Laboratory of Weed and Research Greenhouse of Faculty of Agr...
the effect of different ratio of vermicompost (0, 10, 20, 30, 40 & 50 %) in two type of substrate (coco peat and coco peat-perlite (50:50 v:v)) on growth characteristics of gooseberry (physalis peruviana l.) seedling was investigated in research greenhouse of university of tehran, in 2013. a factorial experiment based on completely randomized design with four replications was carried out. crite...
introduction: the purpose of this in vitro study was to compare the accuracy of the new electronic apex locator raypex5 with radiography for working length determination of straight and curved root canals. materials and methods: twenty straight and single canals of maxillary central teeth and twenty curved mesiobuccal canals of mandibular molar teeth were used. access cavities were prepared and...
Sentence determine the stability mechanisms to stress in Agropyron trichophorum at test with four different levels of osmotic potentials resulted from PEG 6000 including 0, -3, -6 and -9 executed in factorial and accidental manner with four interactions in hydroponic environment. Three genotypes of Agropyron trichophorum pasture types were used Arak (3755), Semirom (3.13), and Faridan (4007) an...
In order to investigate the effect of different levels of water stress on Satureja hortensis, a completely randomized design (CRD) with four replications was carried out in the greenhouse of Yazd University in 2014. The water stress treatments including 100, 75, 50 and 25 Percent of field capacity (FC) were applied. The results showed that water deficit stress significantly (p<0.01) decreased p...
To evaluate the effect of different concentrations of IBA, timing of cuttings and type of plant rootstock in cutting-graft propagation (Omega graft) of Ficus benjamin cv. variegate, an experiment was performed as a factorial in a completely randomized design with three replications in Gorgan University of Agricultural Sciences and Natural Resources in 2012. Each replication consisted of ten sam...
The first experiment was performed to evaluate the effect of vermicompost extract (20, 40, 60, 80, 100%) on seed germination and seedling growth of Plantago psyllium. In second experiment, the effect of solid vermicompost with 4 levels (0, 25, 50, 75) on the emergence and subsequent growth of plantlets was investigated. The 20 and 40% increased germination capacity, germination index, and lengt...
