The purpose of the research was determine the effects of gamma ray on seed germination, seedling height and root length of Rice (Oryza sativa L. spp. Indica cv. MR219) to identify the Lethal Dosage of the radiation. Paddy seeds of MR219 were exposed to different doses of gamma radiations viz 50,100,150,200,250,300,350,400,450,500,600,700,800,900 and 1000 Gy using 60Co as the radiation source. T...

salinity is one of the important factors that reduce the growth and yield of crops in iran; however, determining appropriate methods for reducing its negative effects is important. in order to study the effects of nutritional condition of mother plant and bacterial biofertilizers seed priming on germination indices of wheat (triticum aestivum l.), in salinity condition, an experiment was conduc...

The genus Thymus is perennial medicinal plants belong to the Lamiaceae familythat is used for different propose in pharmaceutical industry. Environmental stresses,particularly salinity, are considered as the major factor reducing plant growth. The purpose ofthis study was to investigate the effects of salt stress on germination characteristics andseedling morphology in two medicinal species of ...

extended abstractbackground and objectives: loquats have formed different ecological types during their cultivation and adaptation in different parts of the world. the first step in the breeding operation is the identifying of the spread center accompanied the studying of the variation between genotypes. in this research, 20 loquat genotypes were evaluated using fruit morphological markers to i...

Seed shape and size are among the most important agronomic traits because they affect yield and market price. To obtain accurate seed size data, a large number of measurements are needed because there is little difference in size among seeds from one plant. To promote genetic analysis and selection for seed shape in plant breeding, efficient, reliable, high-throughput seed phenotyping methods a...
