Andrographis paniculata Nees is traditionally known as Kalmegh, Allelopathic effect of Kalmegh was examined on seed germination and seedling growth of four (Sonalika, VL-914, Euguanda-6 and Mond’s Aids) wheat genotype, the aqueous leaf extracts reduced seed germination and seedling growth of wheat. On the basis of value of per cent reduction in seed germination, germination relative index and v...
Among the Six native species of Juniperus genus in Iran, J. polycarpos and J. excelsa have highest frequent and geographical distribution on the highlands of the country and play a crucial role in the natural ecosystem of presented area. Due to the similar appearance of mentioned species, it's difficult to identify them in the nature. In this study, quantitative traits indicators of cone and s...
Syrian bean caper (Zygophyllum fabago L.) grows in dry and uncultivable wastelands. Because of high tolerance to adverse conditions, an experiment was designed and fulfilled to investigate the effect of two environmental factors, light and temperature, on Syrian bean caper seed germination. Experiment was performed in a completely randomized design with two levels of light (light and dark) and ...
A study was conducted for assessing quality of 15 hybrid rice seed samples and management of seed borne fungal pathogens by three selected chemicals namely Bavistin (0.3%), Thiovit (0.3%) and Provax (0.3%) along with two botanicals such as: Garlic extract (Allium sativum) (1:1) and Allamanda leaf extract (Allamanda cathartica) (1:1) and a bio-control agent BAU-Biofungicide @ 3% (Trichoderma bas...
DOR: 98.1000/2383-1251.1397.5.147.9.1.1578.41 Extended abstract Introduction: Quinoa, with the scientific name (Chenopodium quinoa Willd), belongs to the Spencer family. Seeds vigor can be improved with a variety of seed priming methods. In this method, the seeds are soaked in water or various osmotic solutions and then dried to the original moisture. After priming treatment, seeds are stor...
In order to study the salt tolerance of three species, Coreopsis grandiflora, Celosia cristata and Matthiola incana in germination stage, an experiment was carried out based on a completely randomized design with three replications in Hormozgan University laboratory in 2015. Salinity levels, including 3, 6, 9, and 12 dS/m were applied by dilution seawater and distilled water used as a control. ...
allelopathic plants, because of reduction in herbicide uses, are important in weed management. the allelopathic effects of sage salvia officinalis and white wormwood artemisia sieberi water extract were evaluated on germination and seedling growth of redroot pigweed amaranthus retroflexus at concentration of 0, 5, 10, 15, and 20% in controlled conditions. anova revealed that the extract concent...
Poor germination and low seedling growth of stevia are common problems in the cultivation of the plant. Nutri-priming is a newest, safe, easy, and effective method to increase germination characteristics and seedling tolerance against stress. The objective in this study was to assess the effect of nutri-priming with nano potassium (nano-K), paclobutrazol (PBZ), and salicylic acid (SA) on stevia...
Physiological and biochemical changes during sunflower seed deterioration were studied during incubation for 2, 4, 6 and 8 days at 43 °C and a relative humidity of 100%. Parameters such as germination percentage, germination rate, seedling length, seedling vigor and protein decreased whereas electrical conductivity, fatty acids and lipid hydroperoxides increased during seed deterioration. Incre...
Salinity is a significant barrier to the healthy germination of seeds, development seedlings and ultimately yield crops. tolerance can be effectively induced through seed priming exogenous application various treatment agents. The vegetable crop okra well-liked one worldwide. Literature shows that salt stress negatively disturbs growth plants. In present research, we investigated effects citric...
