Enrichment of marigold (Calendula officinalis) seeds influences seedling vigor and essential oil yield in flowers
Most of soils in Iran are deficient in micro-elements. Enrichment of seeds is found to be as suitable method for overcoming micronutrient deficiencies. Marigold is a herbal medicinal plant. In order to study evaluate of seed enrichment by some of micro-nutrients on seedling establishment and yield of marigold two laboratory and field experiments were carried […]
Phytotoxic potential of Calotropis procera against germination behavior and morphological growth performance of lentil (Lens culinaris)
This study was carried out to assess the allelopathic potential of Calotropis procera against lentil. Four different concentrations of Calotropis procera leaf extracts (100%/, 75%, 50% and 25% concentrated) were used to irrigate pots containing lentil seeds. Allelopathic effects of C. procera on lentil crop were gauged using different germination indices and physical growth parameters […]
Contemporary impact of fly ash with soil and growth hormone on germination status of Peanut (Arachis hypogaea L.)
The work represents the effect of fly ash in germination of Arachis hypogaea L. with different treatment with growth hormone and soil. In the present study, pot experiment has conducted by using different combinations of soil, fly ash, Sodium, Phosphorus, Potassium, Indole Acetic Acid and Gibbrellic Acid NPK, IAA and GA for estimation of plant […]
Propagation of Pentaclethra macrophylla Benth (Fabaceae) through seed and rooting of leafy stem cuttings
We assessed a number of factors controlling seed germination and rooting success of leafy stem cuttings of a high priority fruit (food and medicine) tree species from West and Central Africa, i.e. Pentaclethra macrophylla Benth (Fabaceae). In the case of seed germination, we tested three substrates (soil, sand, and a mixture of soil + sand […]
Allelopathic effects of some medicinal plants on the germination and growth of Chenopodium album L.
This study was conducted at the Laboratory of Medicinal Plants, Payamenoor University of west Azerbaijan-Nagadeh, Iran, in 2012. The water extract was prepared by soaking 15, 30, 45 and 60 gram of plant materials of Moldavian balm (Dracocephalum moldavica L), Lemon balm (Melissa officinalis L.), Cumin (Cuminum cyminum) and Black cumin (Nigella sativa L.) in […]
Study of canola (Brassica napus L.) genotypes for salt tolerance at germination stage via multivariate analysis
This study was conducted to evaluate the effect of salt on the germination and early vegetative growth of canola genotypes. In order to an experiment was performed as factorial form under completely randomized design (CRD) with 3 replications. Genotype factor was contains of 12 genotypes and 6 levels of salt (control, -3, -6, -9, – […]
Evaluation of forage sorghum [Sorghum bicolor (L.) Moench] lines for drought tolerance at germination stage
Drought is a major factor which limits growth and development of higher plants. This study was conducted to evaluate the effect of drought on the germination and early growth of forage sorghum lines. In order to an experiment was performed as factorial form under completely randomized design (CRD) with 3 replications. Line factor contained 15 […]
Multivariate analysis of forage sorghum [Sorghum bicolor (L.) Moench] lines for salinity tolerance at germination stage
This study was conducted to evaluate the effect of salinity on the germination and early growth of forage sorghum lines. In order to an experiment was performed as factorial form under completely randomized design (CRD) with 3 replications. Line factor was contains of 15 lines and 5 levels of salinity (control, -3, -6, -9 and […]
Allelopathic effect of corn, alfalfa, redroot pigweed and bermuda grass on germination and growth of rye
This study was to investigate the effects of the extract from different parts of alfalfa, corn, bermuda grass and redroot pigweed at different stages of growth and in different amounts of extract on rye. For this purpose, a factorial experiment was carried out during 2010-2011. The factors included: type of plant at four levels: 1- […]
Assessment of seed to seed allelopathic potential of Corn (Zea mays L.) on seed and seedling growth of some volunteer species
The experiment was carried out to investigate the effects of interaction seed to seed between corn (Zea mays L.) with some of volunteer species like sainfoin (Onobrychis sativa var. subinermis.), black cumin (Nigella sativa L.), bitter vetch (Vicia ervilia (L.) Willd.), proso (Panicum miliaceum L.) and jimpson-weed datura (Datura stramonium L.) on seed and seedling […]
