Rapid germination is an important factor determining the final yield. This study was performed to investigate the effects of different levels of methanol and drought stress on germination characteristics of lentil seedlings. The experiment was conducted in completely randomized design with three replications in summer 2014 at the Khatam Alanbia University of Behbahan. The first factor was diffe...
This study was conducted at the Gorgan University of Agricultural Sciences and Natural Resources farm, Iran, Golestan province with about 600 mm annual rainfall in order to evaluate the effect of different sowing dates on Azivash (Corchorusolitorius) seed quality, using a randomized complete block design with three replications on 2013. Treatments were four sowing dates such as May 5, ...
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...
any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...
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...
Salt and drought are two major environmental stresses that affect growth and development of plants. In order to study the effects of sodium chloride and polyethylene glycol (6000) on germination characteristics and early seedling growth of redroot pigweed (Amaranthus retroflexus), two completely randomized designs with 4 replications were conducted at Weed Research Laboratory of Bu-Ali Sina Uni...
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...
Marigold (Calendula officinalis) is a medicinal plant belonging to the Asteraceae family, which seems necessary the review of its various features especially the improvement of reproduction in order to the development of vegetation and extraction of raw pharmaceutics materials. In order to study the effects of seed hardening on the quality of seeds harvested from different positions of inflores...
There is substantial diversity in Achillea biebersteinii plants in Iran. It has considerable different biological activities including antibacterial, antifungal, antioxidant, insecticidal, herbicidal and wound healing. Research improvement for medicinal plants depends on the available genetic diversity. The assessment of genetic variability could increase the information for breeding programs. ...
In order to investigate the effects of priming methods on the improvement of seed germination indices and seedling growth of Lallemantia (Lallemantia Iberica) under different salinity levels, two factorial experiment in a randomized complete block design were carried out in the seed technology laboratory of Agricultural Sciences and Natural Resources University of Khuzestan in 2018-2019. In the...
