This research was carried out to define the morphological features of Meckel’s diverticulum (MD) induck and to investigate whether the MD resides in a constant position along the intestinal tract. For thispurpose, a total of 30 adult healthy ducks of both sexes, 50-52 weeks of age were used. After dissecting,some morphological factors such as: total intestine length as well as the lengths of th...
in this study, the genetic diversity of 25 iranian saffron genotypes from three species (crocus speciosus, crocus cancellatus and crocus sativus) has been evaluated using 16 morphological traits and rapd marker. c. sativus was different with speciosus in the leaf number per plant, tepal length, flower weight, inflorescence stem height and the stigma length, but had no significant difference wit...
Root-knot nematodes cause physiological and anatomical disorders in plants. The present study contains the results of an investigation of the effect of Meloidogyne incognita race2 on the growth of roots and aerial organs of tomato under greenhouse conditions. The experiment in a completely randomized design split split plot on two susceptible (Falat Y) and tolerante (Gina VF) tomatoes variety w...
In order to evaluate the growth indices and effective morphological and physiological traits of spring wheat (Triticum aestivum L.) using the multivariate statistical method, an experiment was conducted on the basis of randomized complete block design with three replications in Meshkin Shahr, Ardabil province in 2007. During and at the end of the growth season some physiological and morphologic...
anchusa )boraginaceae( includes weedy species in different habitats and cultivations and is composed of four species in iran. species delimitation is mainly based on features as zygomorphic or actinomorphic flowers, straight corolla tube and nutlet shape. in this project, morphological features of different accessions of anchusa species were evaluated. totally, 33 qualitative and quantitative m...
In order to investigate the morphometric diversity of Moringa populations in ten regions and villages located in Fennuj and Nikshahr of Baluchestan including Bennet, Keshgh, Desc, Madhadi, Nesfaran, Condaran, Tang Fnvjh mouth, and Haft Dokhtaran, Moringa seeds were collected. Twenty Sterile seeds of each genotype were cultured in separate petri diches in three replicates and the culture plates ...
Cadmium (Cd) pollution is a major environmental and human health threat. Therefore there is a need for cost-effective remediation procedures. Chelators such as humic acid have shown positive effects in enhancing resistance to various stresses. The objective of this research was to investigate the use of humic acids at cadmium-contaminated soil on growth and soluble sugar concentration of aloe v...
chemical and morphological characterization of different parts of banana plant(musa paradisica) (peduncle, leaf stalk and pseudo stem) were carried out in orderto assess their potentiality for chemical pulp. each portion was tested forextractives, sodium hydroxide solubility, ash, lignin, cellulose and pentosancontents as well as their fiber length and width. these segmented parts werecharacter...
Response of Iranian Rice Recombinant Inbred Lines (Oryza sativa L.) to Salt Stress in Seedling Stage
Study of the morphological genetic diversity of 114 lines, which have been derived from the crosses between Tarom Mahalli and Khazar cultivars, has been performed at seedling stage as completely randomized design at the normal condition and salinity stress of 8 dS.m-1 in a hydroponic system. Significant differences were detected between genotypes for all traits. Mean of comparison demonstrated ...
