this research was designed to identify garlic (allium sativum l.) bolting clones and determining the relationship between their morphological traits and bolting capacity by using statistical methods of analysis of variance, comparison of means, correlation coefficients, factor analysis, stepwise regression, path analysis and cluster analysis. traits including flowering ability, number, length a...

introduction: nowadays the necessity of the existence of a certain width of keratinized gingiva is emphasized upon to maintain periodontal health and prevent soft tissue recession around teeth and dental implants. this study was carried out to compare two gingival graft procedures including connective tissue graft and graft with a combination of collagen sponge with platelet-rich plasma and pla...

Festuca L. comprises perennial herbs and about 450 species. It belongs to the tribe Poeae R. Br. (= Festucaceae Dumort), subfamily Pooideae of Poaceae. These species are different in leaf size, life duration and lamina width. The genus is divided into two groups based on lamina width: fine-leaved and broad-leaved. In this study, leaf anatomy of F. akhanii, F. elwendiana,F. heterophylla, F. sulc...

thirty pairs ovaries of camel from isfahan abattoiry were collected. in each specimen,  some parameters such as  length, width and thickness of left and right ovaries were measured. for histological studies , after tissue preparation  and staining with h&e;, the ovarian follicles were recognized and classified. for each follicle some parameters such as: diameter of oocyte and follicle, thicknes...

Intensity-modulated radiation therapy (IMRT) represents one of the most significant technical advances in radiation therapy. In the dynamic multileaf collimator (MLC) method of IMRT delivery, because of the relatively small gaps between opposed leaves and because most regions are shielded by leaves most of the time, the delivered dose is very sensitive to MLC leaf positional accuracy. A variati...

Introduction The rate and extent of leaf thickness and area Leaves which develop at elevated CO2 concentrations are development are important determinants of whole often thicker than those on ambient 2 plants. In a plant photosynthetic capacity. The interactive effects study of four Populus clones, Radoglou and Jarvis (1990) of photon flux density (PFD), nitrogen supply and CO 2 found increases...

nowadays, establishment and maintenance of turfgrasses due to high water requirements was faced with serious doubts. hence, screening of drought resistance native grasses, and introduces them as turfgrass is not only effective in reduction of water usage but can also preserve plant gene pools of the country. in the present experiment, wheat grass and bromus as two native grasses were compared w...

The objective of this study was to understand the different morpho-physiological strategies of Ligustrum lucidum, an invasive species occurring in Brazilian forest fragments under heterogeneous light conditions. Ten individuals of L. lucidum were selected and evaluated for morphological of the leaves and physiological traits. For morphological parameters were evaluated: length, width, area, ang...
