Different responses of plant genotypes to the change of environmental conditions have been the most important and challenging issue for plant breeders and agronomists for the selection of superior genotypes. Cumin is one of the most important medicinal and aromatic plants in Iran that are strongly affected by varying environmental conditions. This study was aimed to investigate E×SD interaction...

In order to identify ecotyps of field binweed (Convolvulus arvensis L.), seeds from eight proviences, including 125 populations were gathered and sent to Weed Research Department of Plant Pests & Diseases Research Institute, Tehran, Iran. These seeds planted in a uniform environment condition in Tehran. On the base of 24 morphological and physiological characteristics of seedling that derived f...

Chamomile is a medicinal plant with high economic value. In this research, 20 chamomile ecotypes collected from different regions of Iran were evaluated for genetic and chemical diversity. DNA was extracted by CTAB and polymerase chain reaction was performed using 13 RAPD markers. Essential oils extraction was performed by water distillation using Clevenger system. Components of the essential o...

In order to investigate light and temperature effects on germination of different ecotypes of wild mustard  (Sinapis arvensis L.), seeds were collected from four regions: Fars, West Azarbayjan, Khouzestan and Mazandaran Provinces. Seed size and weight, difference of dormancy state among the ecotypes, seed germination in differential light and temperature conditions were studied. The results sho...

salinity is one of the most restrictions in plant growth in dry and semi dry land which effects production of many crops such as sesame. in order to study the phenology and morphology characteristics of 43 ecotypes and line of sesame (sesamum indicum l.) under salinity of irrigation water (5.2 ds.m-1) a field experiment was conducted at research farm of center of excellence for special crops, f...

fennel is one of the oldest herbs and possesses appealing flavor and beneficial medicinal effects. fennel(foeniculum vulgare mill.) belongs to the apiaceae family and its essential oil and seeds are used to flavor foods including meats, ice cream, candy, baked goods and condiments. the increasing commercial value of fennel necessitates the need to develop elite ecotypes with high essential oil ...

Genetic diversity of 12 lemon balm ecotypes was evaluated using agronomic traits as well as ISSR and RAPD markers. Results of analysis of variance showed high diversity among the studied ecotypes. Cluster analysis using UPGMA method grouped the ecotypes into three different groups based on the agronomic traits. Twelve ISSR primers created 106 polymorphic bands among the studied ecotypes. An ISS...
