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...

There has been some concern about using small seeds that may result from seed position on the ear or poor growing conditions for seeding hybrid maize. This study was designed to investigate the effect of seeding three commercial maize crosses (Single Cross 2010, Three-Way Cross 310 and Three-Way Cross 321) with three seed sizes (large, medium and small) under seven salinity levels of irrigation...

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...

Seed priming is a technique which is potentially able to promote rapid and more uniform seed germination and plant growth as well. In this regards, the presowing effects of seed priming treatments were investigated on some physiological viz. seed germination, germination rate, radicle elongation, shoot elongation, radicle dry weight, shoot dry weight and vigor index. Seeds were subjected to two...

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...

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...

abstract in order to study the effect of different water potential on anethum graveolens two experiments were conducted for germination and vegetative stages. this study was carried out as a factorial experiment based on completely randomized design with three replications. in the first experiment, response of dill seeds germination to levels of drought stress including to drought potentials ze...
