Salvia limbata .C. A. Mey is a herbaceous perennial plant whit proven medical effects, belongs to the family Lamiaceae. The objective of this study is to investigate the quantitative and qualitative variability of the essential oil of this species cultivated in new conditions (Karaj and Abhar) Compared with wild population (Semnan). The aerial parts of the plants were collected at the flowering...
abstract three separate greenhouse experiments were conducted in the greenhouse facilities of the iranian plant protection research institute, tehran, to study the efficacy of some accase inhibiting herbicides for control of resistant based on mechanism, resistance based on enhanced metabolism and susceptible wild oat biotypes. in each experiment, biotypes were treated separately by 17 herbicid...
Forty-one wild sheep (Ovis ammon orintalis) from Kabodan Island of National Park of Urmia Lake (North-West of Iran), were examined during a period of six months from October 2002 to March 2003, for helminthes and coccidian infection. The numbers of oocyst and eggs per gram of faeces (OPG & EPG) were determined by the centrifuge flotation technique using saturated sugar solution. The rate of inf...
Maintaining genetic integrity is essential for in situ and ex situ conservation of crop wild relative (CWR) species. However, introgression of crop alleles into CWR species/populations may change their genetic structure and diversity, resulting in more invasive weeds or, in contrast, the extinction of endangered populations. To determine crop-wild introgression and its consequences, we examined...
The aim of this study was to investigate and to quantify the effect of burial depth on seedling emergence of volunteer canola and wild mustard. Seeds were buried in 12 different depths (1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 30 cm) in 4 replications and seedling emergence was measured daily. Results indicated that emergence percentage of volunteer canola was around 98 % from 1 to 2.9 cm of burial...
Several ethnobiological studies have used the Jaccard Index, a qualitative, binary measure, to compare group similarities and differences in lists of plant animal species, medicinals, foods, cultural utilities, so on. We extend this effort by formulating Nolan new, more precise quantitative measure relative frequency listed items between groups . It is deployed here evaluate degree similarity f...
The wild relatives are important sources of genes for some desirable traits and adaptation to environmental conditions that can be exploited to enrich the cultivated safflower gene pool. In this study, genetic relationship and finding chance of specific markers between three species of the genus Carthamus, including tinctorius, lanatus and oxyacantha were evaluated by 9 ISSR primers. The s...
The DUF1644 family is a highly conserved and functionally unknown protein it has been demonstrated that significantly improved the salt tolerance of rice (non-halophytes). However, little understood about function gene in halophytes. This study aimed to investigate whether similar non-halophytes as halophytic species. functions ZmDUF1644 transferred from Zoysia matrella into non-halophytic Arab...
BACKGROUND We compare traditional knowledge and use of wild edible plants in six rural regions of the northwest of the Iberian Peninsula as follows: Campoo, Picos de Europa, Piloña, Sanabria and Caurel in Spain and Parque Natural de Montesinho in Portugal. METHODS Data on the use of 97 species were collected through informed consent semi-structured interviews with local informants. A semi-qua...
