Influence of salicylic acid pretreatment on germination and seedling growth of wheat (Triticum aestivum L.) cultivars under salt stress
Salicylic acid is enhances salt tolerance in wheat seedlings and resistance to water deficit. The experiment was applied to determine the effect of salicylic acid pretreatment on wheat germination and seedling growth under salt stress. Traits such as seed germination, root length, shoot length, seedling fresh weight, germination rate and seed vigor index were evaluated. […]
The effect of kinetin treatment on indices of germination and activity of canola seed enzymes under salt stress
An experiment was conducted in agricultural plants physiologic laboratory in agriculture faculty of Islamic Azad university of Saveh branch. Improved canola seeds of Isfahan 14 cultivar were treated by chemical substance of kinetin in four levels of 5(control), 10, 15 and 20 ppm. NaCl was used in four levels of 0(control), 70,140 and 210 mg/lit […]
The effect of seed pretreatment by salicylhydroxamic acid on germination indices of safflower under salinity stress
In order to study the effect of seed pretreatment by salicylhydroxamic acid on germination indices and enzymes activity of safflower (Carthamus tinctorius L. var. Esfahan 14) under salinity stress in Iran. The experiment was laid out in a factorial design with four salicylhydroxamic acid levels of 0 (control), 50, 75, 100 ppm and four levels […]
Some changes in germination and morphological traits of black seed under different soil types and common bean densities
A split-factorial experiment on the basis of randomize complete block design with three replications was conducted in 2012, to assess the effects of different common bean (Phaseolus vulgaris L.) densities (0, 1, 2 and 4 per pot) and soil types (soil of wheat and barley fields) on some changes in germination and morphological traits of […]
Evaluation of allelopathic effects of Calotropis procera against wheat (Triticum aestivum) using seedling vigor and germination indices
Many plants are known for their phytotoxic potential. Such plants tend to suppress the germination and normal growth processes in other plants under their effect. Calotropis procera is one of the most dominant weed plants in Pakistan and is largely known for its insecticidal, pharmacological and phytotoxic properties. It is found abundantly around and inside […]
Germination parameters and peroxidase activity of Lettuce seed under stationary magnetic field
The magnetic fields influence the biological systems by several mechanisms. The magnetic field induces the translation and rotation movements of the electric charges. The effects of a stationary magnetic field on the germination and initial stages of growth of Lettuce seeds (Lactuca sativa var.longifolia) have been studied. The seeds were exposed to a magnetic field […]
Allelophatic effect of sunflower parts extract in different growth stages on germination and seed production of redroot pigweed (Amaranthus retroflexus)
Because of prevalence and importance of redroot pigweed (Amaranthus retroflexus) in most fields, a factorial experiment in three replicates was conducted in greenhouse conditions. The examined factors were extracting of different parts of sunflower (leaf, stem, root and whole plant), different extract concentration in 5 levels (extract as 1:20, 1:15, 1:10, 1:5 and control) from […]
The effect of silicon on germination and some growth characteristics of salt-stressed canola seedling
The effects of salinity and supplemental silicon on germination and some seedling traits of canola, cv. Talayeh was investigated in a complete randomized block design. The first factor was 5 levels of potassium silicate (0, 1, 2, 3 and 4 g/l) and different levels of salinity as second factor (including 0, 60, 180, 120, and […]
The allelopathic effect of different species of grapevine berries aqueous extracts on some germination parameters of lettuce (Lactuca sativa L.) seeds
Allelopathic potential of twelve local varieties of grapevine Vitis vinifera fruits: taefi; zareg-dohuok; Baetmuni; Black-manga; Sarqala-bakrajo; Awelka; Rash-merii; Mala-Hassan; Ashgar-basraha; Kamalii; Toli-mawelian and Shekh-nuraddin on some germination and growth parameters of lettuce seeds Lactuca sativa has been investigated . The aqueous extracts caused significant inhibitory effects on germination rate; germination speed; radical length; plumule length; […]
Effect of aqueous extracts of Chrozophora obliqua (Del.) Juss. on germination and seedling growth of Zea mays
The allelopathic influence of aqueous extracts of Chrozophora obliqua (Del.) Juss. on the germination and seedling growth of Zea mays have been determined. It was noted that 10g aqueous extracts of leaves and 48hr treatment present significant inhibitory effect on germination, radical length and number of seminal roots and the effect was found significantly higher […]
