Allelopathic materials enter to the environment by plants through different ways. This compounds cause an important ecological processes in other plants. The purpose of this experiment, evaluation of the allelopathic potential of stem and flower organs of Orobanche aegyptiaca weed and a mixture of them on morpho- physiological and biochemical characteristics of Lycopersicon esculentum. For this experiment, a 5% suspension of these organs and their mixtures on Lycopersicon esculentum seedlings were applied in hydroponic culture. According to the results, studied characteristics of Lycopersicon esculentum under aqueous extract of stem and flower of Orobanche aegyptiaca and mixture of them demonstrated different behavior compared with the control. Most decreasing effect on root length, leaf area, seedling dry weight, content of total chlorophyll and carotenoid pigments of Lycopersicon esculentum were observed in the flower organ of Orobanche aegyptiaca. Amount of damage to protein and starch were decreased with an increase of total phenol in Lycopersicon esculentum under aqueous extract of various treatments of Orobanche aegyptiaca especially flower.

Identification of quantitative traits loci, especially in stress, is one of the important issues in plant breeding. The present study was conducted to identify molecular markers that have a significant relationship with related traits in rice using ISSR markers and 59 rice genotypes and 21 agronomic traits in the flooding and drought stress conditions. The genotypes were based on ISSR markers in a total of 144 bands with an average of 14.4 bands for each marker, and of 144 bands, 69.17% of the bands were polymorphic. The largest polymorphic information content (PIC) was initiated by ISSR-7 with 0.49 and the ISSR-2, ISSR-8, ISSR-9 and ISSR-10 primers with the lowest PIC of 0.47. The association analysis was performed using population structure matrix with GLM and MLM statistical models using the TASSEL software for 21 variables. The MLM model was able to detect meaningful markers in flooding condition of 96 markers in drought stress conditions and related to 21 traits examined at a probability level of 5%. According to the results of association analysis in flooding conditions, the highest correlation coefficient (in the MLM model) of the ISSR27-2 allele was 29.27% and in the drought stress, the highest correlation coefficient (in the GLM model) was related to the ISSR1-6 allele of 77.7 22 percent. According to the results, it is anticipated that the use of ISSR markers detected in this study, if confirmed and after being confined, is highly confident in the selection breeding programs with the help of the molecular marker.

In order to identify QTLs controlling agronomic traits in 103 F3 families of Barley derived from cross Badia × Kavir was conducted based on randomized complete block design with three replications in 2014-2015 years, at the Faculty of Agriculture and Natural Resource of Gonbad Kavous University. For linkage map construction, 69 ISSR polymorphic alleles and 7 SSR markers were used that covered 698 cM of the barley genome. 23 QTLs were identified. Among these mapped QTLs, qSW-3 (between ISSR29-7-ISSR31-5) and qSW-4 linked to (ISSR20-1), qSW-4 (between ISSR131-1-ISSR16-4), qSW-5 (between ISSR47-6-ISSR30-3), qSW-6 (between ISSR48-5-ISSR47-7), qSW-6 (between ISSR22-6-ISSR30-1), qSW-7 (ISSR48-1) for spike weight and qGL-4 (ISSR20-1) for grain length identified as major QTLs. It is suggested that Major QTLs should be considered in plant breeding programs and marker-assisted selection.

In order to micro-morphology study of seed Rubus L. seven seed specimens were collected from different habitats in North of Iran stereo and SEM microscopic methods were applied. The characters were evaluated included dimension, shape, size, trichome and ornaments on surface. The results demonstrated that the mean size of seed was 2-4 mm; the biggest pyrenes were seen in R.caesius, R.sanctus and smallest in R.hirtus, R. dolichocarpus. pyrenes were formed in different shapes e.g., reniform (R. caesius), triangular form (R.discolor), elliptical form (R.hirtus, R.dolichocarpus, R.hyrcanus), ovate form (R. persicus) and oblique form (R. sanctus). Ornaments on the endocarp surface were presented variably; proments of surface was varied from low to high in treated species. White color was seen in all examined species. Stellate and simple trichome just presented in R. sanctus. General results confirmed that pyrenes morphology of Rubus were valuable character for identification.
