this study was conducted for the first time in order to introduce the pioneer forest trees and medicinal sea-buckthorn (elaeagnus rhamnoides) and determine the characteristics of the species seeds from seven provenances, including iran, china and tibet in the laboratory. after site identification of the species, seeds were collected from the regions including alborz, mazandaran, eastern azerbai...

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...

The effect of leachates of different phenological stages of Cassia occidentalis L. on Parthenium hysterophorus L. was studied. Seed germination, radicle length, plumule length and fresh and dry weight of Parthenium were recorded. Pigments and protein contents were also measured to evaluate relation between biochemical and biophysical parameters of Parthenium under stress. The leaf leachate of C...

The increasing intensity of coronavirus (COVID-19) spreading emphasizes the significant development in home food production to reduce incoming socioeconomic impact from soaring prices, supply chain fragility, and severe economic crisis. This preliminary study was initiated demonstrate possibility using electrospun fibers as a potential substrate application seed germination activity. drive this...

Objective: To evaluate ten triticale genotypes to assess the quality of seeds under two production systems, with cut and without cut, in municipalities Matamoros (L1) Francisco I. Madero (L2), Coahuila,Mexico.Design/Methodology/Approach: The agronomic variables evaluated were: Grain yield (GY), number per spike (NSS), length (SL), spikelets (SS) plant height (PH). Variables laboratory normal se...

the present experiments is deciding to study the effect of hematite and volcanic ash on growth and physiological traits in sorghum factorial in a randomized complete design with  treatments and replications treatments consisted of volcanic ash concentrations (0, 0.25 and 0.5 g), hematite at three concentrations (0, 0.25 and 0.5 g), respectively. the results showed that the largest radicle and p...

physiological effect of six levels of water stress (0, -0.1, -.03, -0.6, -0.9 and -1.2 mp) was studied on seed germination and plumule as well as radicule growth length in three species namely: agropyron elongatum, agropyron desertourm and secale montanum. polyethylene glycol (peg) was used to provide appropriate water potentials. a total of 100 seeds in four replications (petri dishes) were so...
