In this study, in order to investigate morphological characteristics, yield of fiber, essential oil and seed oil yields, seeds of two native ecotypes from Iran and one foreign variety (Fedora17) with its progenies (Fedora17-2) were cultivated in research fields of three locations (Gilan, Golestan, and Alborz province) in Iran and their morphological and phytochemical characteristics were studied. The greatest height and shoot dry matter were observed in Fedora17 and its progenies while the widest coverage and thickest stem was observed in the native ecotypes of Iran. Also, the oil content varied from 18.88% in Fedora17-2 to 40.09 % in Yazd. The highest oil yield was observed in native ecotype of Fars (820 kg ha-1) and Yazd (830 kg ha-1). Plant height fluctuated from 99.7 cm in Safrabasteh to 197.5 cm in Alborz. Fiber yield ranged from 1569 kg ha-1 in Safrabasteh to13991 kg ha-1 in Alborz. The hemp cultivated in Alborz, in terms of morphological and reproductive properties and fiber yield was significantly better compared to the other stations. The oil yield per plant was 11.35 kg in Chalaky station to 36.39 kg in Alborz  station. Therefore, cannabis cultivation is recommended in Alborz with average production of 13991 kg ha-1 fiber, 2.2 t ha-1 essential oil and 1110 kg ha-1 seed oil. The foreign cultivars with the tallest stem and the highest percentage of stem dry matter were proper for fiber production. In addition, the morphological characteristics of Fedora 17 were also preserved in its progeny.

Alloxysta turcica Tataroğlu & Katılmış, 2023, a species recently described from Turkey, is now being synonymyzed with A. minuscula Andrews, 1978. This decision is based on morphological analysis, which has revealed significant similarities between the two species. The reasons and supporting illustrations for this synonymy are provided.

In order to investigate the possibility of quinoa producing in Garmsar, Iran, a factorial experiment conducted in randomized complete block design with three replications in 2018-2019 growing season at Garmsar Agricultural Research Station. The factors were planting date at three levels (March 6th, April 1st and April 6th) and the three genotypes of quinoa (Q26, Q29 and Titicaca). Results showed that the effect of planting date was significant for all studied traits except the harvest index. Also, all studied traits were significantly different in all genotypes. Titicaca planted on March 6th had the highest yield (2276 kg.ha-1).The grain yield and yield components decreased with the delaying the planting date. Compared to early plantings, Latest date, April 6th, led to reduction of all traits, especially grain yield (about 50%). The results of simple phenotypic correlation between the studied traits showed that grain yield per hectare had the highest correlation with plant yield (0.877) and then with leaf area index (0.832), panicle weight (0.815) and number of branches per plant (0.745) that was significant at the 1% probability level.

Morphological and ecological variations and inter-specific relationships of a red algal genus, Hypnea were investigated in 15 populations belong to 5 species from Oman Sea coasts. In this study, cluster analyses, principal component analysis and Canonical Correspondence Analysis were done. Statistical analyses indicated that characters such as special branches or branchlets, position of tetrasporange and algae habit are the most important diagnostic characters in intera-genus variation. In general two major clusters were formed. The first major cluster comprised H. boergesenii. Second major cluster contains two subclusters. The first subcluster comprised of H. charoides, H. valentiae and H. musciformis. The second subcluster comprised of H. pannosa. Results showed that variation in the cluster one was explained by average of annual salinity and morphological variation and in cluster two was related to average of annual PH, water temperature and impurities.

Typological classification is historically the first manifestation of typology in modern linguistics, starting with the morphological classification of language in the nineteenth century. Morphological typology usually recognizes three canonical types of language: isolating, agglutinating, and fusional, to which is sometimes added a fourth: polysynthetic. The majority of the worlds languages do not correspond to these types. In fact, the traditional morphological typology involves a language as a whole, not a particular construction. It could just as easily be applied to different parts of the linguistic system. For instance, the nominal system of a language may be agglutinative while the verbal system is fusional.

The aim of this research was investigation on relationship of vegetation and soil in river banks of dryland regions. The two study areas selected for with different type vegetation cover. According to this selected 2 transect with 500 m length and distance 50m quadrates in 3 x 3m and quadrates 1 x 1m were sampled for vegetation analysis from the river banks. The parameters measured included canopy surface area, bare soil area and litter. Five soil samples was taken from the 0-45 cm depth at each location, and analyzed for pH, EC, available phosphorus, available potassium and texture. Data analyzed using SPSS software. The data shows that there have been plants such as Tamarx, Salsola and Hammada in end of river. Average of vegetation cover, bare soil surface and the litter were 14.8, 79 and 6.2%, respectively. Also, in up of study area has been occupied by Haloxylon and Hammada. Average of mention parameters were 12, 81.2 and 6.6%, respectively. Analyzed of vegetation shows that no significantly between canopy, bare soil area and litter in two areas. Analyzed of soil characteristics shows that there are significantly between soil samples in two regions. Therefore, the data shows that the soil causes difference in vegetation on river banks.

BACKGROUND AND OBJECTIVES: Formalism is one of the schools of literary criticism that pays attention to the form of the literary work and played a major role in the creation of the theory of structuralism. The best field for formalist theories and structuralism is folk, folkloric and indigenous stories. According to the formalist point of view, all of these stories, while having variable characters, have specific and specific functions and actions. Weiss and Ramin"s poem is also a romantic genre with variable characters and specific actions. In this article, an attempt is made to examine the motifs of Weiss and Ramin"s story, based on Vladimir Propp"s structural model, in order to understand the similarity of the actions of the characters of romantic stories in different forms of the story. METHODOLOGY: The research method in this article is descriptive-analytical and gathering information through studying, scanning and sampling library documents and databases. FINDINGS: Weiss and Ramin"s system has ten suspensions, three climaxes and seventeen functions. The characters are divided into main and secondary categories, where Weiss and Ramin are among the main characters and Mobed, Shiro, Daye, Viro, Zard and Gol are among the secondary characters. From the perspective of prop division, there are seven roles in this system, which are divided into two groups of active and passive characters. Weiss and Ramin are among active actors, and Mobed and Gol are among passive, victim and productive actors. CONCLUSION: Based on Vladimir Propp"s model of structuralism, it can be concluded that in lyrical stories, even with the existence of different forms and multiplicity of characters, self-work, function and actions are limited and specific.

Carex, the largest genus of Cyperaceae family in the world and Iran, includes four subgenera, of which the subgenus Carex with 68 species in Flora Iranica area and 44 species in Iran is the largest subgenus. Due to morphological similarities between species, this genus is composed of several complex groups. The reproductive structures (inflorescence and flower) in this genus, especially utricle and nut, are of special importance for the identification and delimitation of species. In this research, the utricle characters among Carex species in Iran have been studied. In order to evaluate the morphological and micromorphological characters, herbarium samples were used and the obtained data were analyzed using PAST software Ver. 3. 14. Utricle shape (general and transverse view ), winged or wingless margin, wall material, the presence of veins and its number, the presence of hair and beak (shape and length ) were more important than other characters. Identification key was prepared based on morphological characters for subgenus Carex in Iran. The morphological traits of utricle were useful only at the species level but were not effective at the section level and also the micromorphological traits were not effective at either the species level or the cluster level. Also, cluster analysis based on utricle morphological data did not confirm the conventional classifications of sections in the Flora Iranica and the Flora of Iran, but showed more agreement with phylogenetic results.
