کادمیوم، عنصری غیرضروری و سمّی برای گیاهان است که از طریق فعالیت های مختلف بشر وارد خاک می شود. این عنصر تأثیرات فیزیولوژیک و مورفولوژیک متعددی بر گیاهان دارد. با این حال، برخی گونه های مقاوم به کادمیوم توانایی جذب و انباشتگی این فلز را در بافت های خود دارند. یکی از گیاهانی که می تواند در خاک های آلوده به کادمیوم رشد کند، گیاه matthiola chenopodiifolia است. در این مطالعه، مقاومت، جذب و انباشتگی ...
During a diversity study of entomopathogenic fungi in an agricultural ecosystem, two were collected, isolated, and identified based on molecular phylogenetic analyses three nuclear loci (LSU, TEF1, RPB1) combined with morphological data. In this study, one novel species is described, Ophiocordyceps flavida, new record Pseudogibellula formicarum for Thailand. flavida morphologically resembles th...
In order to study the salt tolerance of three species, Coreopsis grandiflora, Celosia cristata and Matthiola incana in germination stage, an experiment was carried out based on a completely randomized design with three replications in Hormozgan University laboratory in 2015. Salinity levels, including 3, 6, 9, and 12 dS/m were applied by dilution seawater and distilled water used as a control. ...
Random amplified polymorphic DNA (RAPD) technique is a simple and reliable method to detect DNA polymorphism. Several factors can affect the amplification profiles, thereby causing false bands and non-reproducibility of assay. In this study, we analyzed the effect of changing the concentration of primer, magnesium chloride, template DNA and Taq DNA polymerase with the objective of determining t...
Two new species of Oreocharis Benth. from Fan Si Pan, the highest mountain in Vietnam (Sa Pa) are described and illustrated. Oreocharis grandiflora W.H.Chen, Q.H.Nguyen & Y.M.Shui, is similar to O. flavida Merr. from Hainan province, China, but differs mainly by its larger and infundibuliform corolla, stamens adnate to the base of the corolla tube and stamens coherent in two pairs. The second, ...
