Systematic Studies of Subspecies of Hordeum murinum in Khuzestan

In this work 47 quantitative and qualitative anatomical characters of the flag leaves of two subspecies H. murinum L. ssp.glacum Steudel (Tzvelev) and -ssp. leporinum Link (Arcangell) were studied, characters such as location of the macro hairs and silica cells, shape of the short cells and bulliform and venation type were distinct among the two subspecies. Statistical analyses showed significant differences in 17 quantitative characters such as the number and width of long cells, number, length and width of short cells and stomata. The results of PCA (Principle Component Analysis) showed that the first component indicate %72 of total variation. The number of long cells and number of prickle cells in coastal zone showed the most correlation. H. murinum ssp. glaucum had chromosom number 2n=14 and –ssp leporinum had 2n=28 chromosomes. Results showed that polyploidy levels related to characters such as: number and width of long cells, number, length and width of short cells, number and width of long cells, number, length, width and number of rows of stomata cells, number of macro hairs, width of bulliform cells, number of outer bundle sheath cells in small vascular bundle.
