Extended Abstract Introduction: Germination is considered the first and most important stage of establishment and consequently, successful competition which is influenced by genetic and environmental factors. Among the environmental factors influencing the germination, temperature and light are the most important ones. Using different models, the germination response of seeds to temperature c...
In order to study drought stress effect at the reproductive stage on seed germination characteristics of seven rice genotypes, an experiment was carried out at Sari Agricultural Sciences and Natural Resources University in 2014. This study was conducted on drought-stressed seeds and seeds grown under normal conditions. The results of orthogonal mean comparison among non-stressed seeds showed th...
In recent years the use of allopathic effects on weed management seems to have attracted many professionals. In order to investigate the effect of aqueous extracts of Yarrow (Achilla wilhelmsii L.) and Habek mint (Mentha longifolia (L.) Huds) medicinal plant on germination indices of plantain, two experiments were conducted in completely randomized design with three replications in 2014 in the ...
Environmental stress, particularly drought stress can play an important role in reducing plant growth especially during the germination stage in arid and semi-arid regions in Iran. For cultivation of medicinal plants in arid and semi-arid areas, the assessment of their tolerance is very important. In this research, in order to evaluate the effects of salicylic acid pretreatment on enhancement o...
The changes in lipid and fatty acid contents after soaking, cooking, germination and fermentation of three white sorghum varieties were studied to improve cereal quality. The results revealed that oil in raw sorghum varieties ranged from 3.58 to 3.91%, respectively and ‘Dorado’ represents the highest variety in oil content. As general trend after germination, oil content was decreased. Fatty ac...
This study was carried out in the biotechnology laboratory of Agricultural Faculty of Ondokuz May s University. The objective of this study was to establish the effects of chilling period and chilling temperature on germination in linseed (Linum usitatissimum L.). Seeds were subjected to six different heat temperatures (0, 2, 4, 6, 8 and 10 C) for 24, 48, 72, 96, and 120 hours. Germination test...
Extended Abstract Introduction: Schrophularia striata is one of the medicinal plants of the Scrophulariaceae family and contains phenolic compounds. Locals have traditionally used this herbal medicine to treat infections caused by wounds, gastrointestinal diseases, and eye diseases. Due to excessive consumption by indigenous people and climate change, especially increasing temperature, the col...
Extended Abstract Introduction: Drought stress, as abiotic and multidimensional stress, has severe effects on plant growth. One of the new approaches in the management of drought stress is the use of nanoparticles. Nanoparticles infilterate the seeds and increase nutrient and water uptake and ultimately, improve germination. The present research was conducted to evaluate the effects of titaniu...
