A cDNA encoding a nucleolar protein was selected from a pea (Pisum sativum) plumule library, cloned, and sequenced. The translated sequence of the cDNA has significant percent identity to Xenopus laevis nucleolin (31%), the alfalfa (Medicago sativa) nucleolin homolog (66%), and the yeast (Saccharomyces cerevisiae) nucleolin homolog (NSR1) (28%). It also has sequence patterns in its primary stru...

The current study aimed to investigate the effect of two abiotic stresses including salinity and drought on seed germination characteristics of Allyssum hamalocarpum in vitro. The experiment was designed as factorial completely randomized with four replications. Treatment included five levels of drought i.e. 0, – 0.19, – 0.25, – 0.41 and – 0.99 Mpa and five levels of salinity including 0, 50, 1...

calotropis proceran (asclepidaceae) is an evergreen plant and widely distributed in hormozgan province. this plant has the allelopathic properties including germination inhibition, plumule and radicle growth reduction. in this study the effect of different concentrations (0, 5, 10, 20, 40 and 60%) of dry leaf water extraction of this plant on the germination of cucumber (cucumis sativus), tomat...

Abstract The goal of this study was to look into growth changes and a number metabolic events in Fe 2+ treated Lupinus albus, Triticum aestivum , Vicia faba, Zea mays plants assess the role biosorption by Rhodotorula mucilaginosa YMM19 alleviate these changes. effect concentrations (untreated with biosorbent) on seed germination studied. T. plumule stimulated low dose . However, application red...

REMATURE germinating seeds have been observed in various plants, including P lemons, oranges, melons, wheat and rye. However, in none of these is there any good indication that the premature germination is the result of changes in the germ plasm. Only in maize has the genetic control of this phenomenon been clearly demonstrated. Such mutants have been described by MANGELSDORF (1923,1926, and 19...

The aqueous extract from Carya cathayensis Sarg. exocarp was centrifuged, filtered, and separated into 11 elution fractions by X-5 macroporous resin chromatography. A phenolic compound, 4,8-dihydroxy-1-tetralone (4,8-DHT) was isolated from the fractions with the strongest phytotoxicity by bioassy-guided fractionation, and investigated for phytotoxicity on lettuce (Latuca sativa L.), radish (Rap...

Pyrethrum is a perennial daisy grown commercially for the insecticide that is extracted from its flowers. In order to evaluate germination and seedling growth of pyrethrum under different temperature and drought stress treatments, an experiment was conducted in seed technology laboratory of Faculty of Agriculture of Islamic Azad University of Isfahan branch in 2018. During this experiment, poly...

To assessment effect of concentration and times of disinfection wheat seeds, infected by Aspergillus fungus a research was conducted based on Factorial experiment according randomized complete block design with four replications. The factors included four levels of sodium hypochlorite (2, 4, 6, and 8%) and four times of seed disinfection (2, 5, 7, and 10 minutes). Result of analysis of variance...
