As organisms exposed to various abiotic and biotic environmental impacts, plants are able to recognize and respond to their surrounding environment with high specificity. Electromagnetic field radiation is an important effective stress factor on growth and development of plants. Our research focused on plants grown from wet pretreated seeds with low frequency electromagnetic field exposure comp...

A major problem of arid and semi-arid regions is environmental stresses like salinity and drought. To study the effect of Artichoke germination under different levels of salinity and drought, two separate experiments were performed. The experimental treatments included different salinity levels of NaCl (0, 50, 100, 150 mM) and five drought levels by PEG (0, 10%, 15%, 20% and 25%) with three rep...

  The aim of the present study was to determine effects of artificial drought stress on the characteristics of germination and seedling growth in bread wheat cultivars. The material of experiment consisted of seeds obtained from eight bread wheat cultivars with different response to drought (Alpu 2001, Sultan 95, Konya 2002, Eser as sensitive cultivars; Karahan 99, Tosunbey, Kate A1 as resista...

objective: cigarette is a rich source of oxidants and reactive nitrogen species. nitric oxide (no) in high concentration has deleterious effects on human sperm function. antioxidant defense system in seminal plasma protects spermatozoa from the attack of reactive oxygen metabolites. the purpose of this study was to determine the correlation between cigarette smoking with the no levels and the t...

Objectives Root resorption is a dangerous side effect in orthodontics, and maxillary incisors are at the highest risk for root resorption. It is important to understand optimal force considerations for patients with altered root lengths.The purpose of this study was to investigate the effects of root length on stress distribution on roots by means of three dimensional fi...

Maize (Zea mays) root system architecture (RSA) mediates the key functions of plant anchorage and acquisition of nutrients and water. In this study, a set of 204 recombinant inbred lines (RILs) was derived from the widely adapted Chinese hybrid ZD958(Zheng58 × Chang7-2), genotyped by sequencing (GBS) and evaluated as seedlings for 24 RSA related traits divided into primary, seminal and total ro...

the investigation was conducted on wet and dry seasons of ethiopia during the year 2012/2013 at wondo genet agricultural research center nursery site. four levels of cutting size and three levels of cutting positions were arranged in randomized complete block design with three replications. data on seedling height, branch number/seedling, root number/seedling, root weigh/seedling, root length/s...

Root development of Arabidopsis, Zea mays (maize) and Oryza sativa (rice) differs in both overall architecture and the anatomy of individual roots. In maize and rice, the post-embryonic shoot-borne root system becomes the major backbone of the root stock; in Arabidopsis, the embryonic root system formed by a simple primary root and its lateral roots remains dominant. Recently, several specific ...
