دارواش یک گیاه همیشه سبز، پایا و انگلی است که همه آب و عناصر ضروری خود شامل نیتروژن و یک بخش کوچک از غذای خود را از درخت میزبان و توسط یک اندام ریشه مانند به نام هوستوریوم دریافت میکند. این گیاه از نظر پزشکی و دارویی بسیار اهمیت داشته و بسیاری از اثرهای آن در درمان بیماریها به اثبات رسیدهاست. دو گونه Viscum album L. (دارواش حقیقی) و Arceuthobium oxycedri (D.C.) M. Bieb. (دارواش کاذب) هر دو از...
عوامل تهدیدکنندة پایداریِ جنگلها طبیعی و انسانیاند. عوامل انسانیِ تخریب جنگلها شامل چرای دام، آتشسوزی، تغییر کاربری، بهرهبرداری معدن، قاچاق چوب، و رهاسازی زباله در جنگل است. چرای دام در جنگلها آثار تخریبی زیادی دارد. در این مطالعه، اثر چرای دام بر پیدایش، تنوع، و تغییر گونههای جنگلی در گروههای زادآوری بررسی شده است. منطقة مورد مطالعه، گاوسراهای بنجهبن و پاتم، واقع در بخش پاتم جنگل آموزشی...
Salt tolerance mechanism of an extreme halophyte Salvadora persica was assessed by analyzing growth, nutrient uptake, anatomical modifications and alterations in levels of some organic metabolites in seedlings imposed to various levels of salinity (0, 250, 500, and 750 mM NaCl) under hydroponic culture condition. After 21 days of salt treatment, plant height, leaf area, and shoot biomass decrea...
The present study describes the wood microstructure of Azima tetracantha, Salvadora oleoides, and S. persica, the members of family Salvadoraceae represented in the Indian Subcontinent. An identification key based on wood anatomical features has been developed for the separation of the species. SEM studies revealed the presence of vesturing in intervessel pits of Salvadora.
Salinity-induced modulations in growth, photosynthetic pigments, relative water content (RWC), lipid peroxidation, photosynthesis, photosystem II efficiency, and changes in activity of various antioxidative enzymes were studied in the halophyte Salvadora persica treated with various levels of salinity (0, 250, 500, 750, and 1000 mM NaCl) to obtain an insight into the salt tolerance ability of t...
Title of Dissertation: ROLE OF PEACH [PRUNUS PERSICA (L.) BATCSH] EXTRAFLORAL NECTARIES IN MEDIATING NATURAL ENEMY-HERBIVORE INTERACTIONS Clarissa Ruth Mathews, Doctor of Philosophy, 2004 Dissertation Directed By: Professor Dale G. Bottrell Department of Entomology Extrafloral nectaries (EFNs) are reported to benefit some plants when ants (Hymenoptera: Formicidae) use their secretions and fend ...
Received: 10 April 2013 Accepted: 5 Dec 2013 Abstract Background and Aim: Several techniques have been used to assess the efficacy and substantivity of mouthwashes. Considering the variability of available mouth rinses, this study aimed to assess the substantivity of several mouthwashes and their effect on microbial plaque using an epifluorescence microscope. Materials and Methods: This crossov...
Response of Peach Scion Cultivars and Rootstocks to Meloidogyne incognitain Vitro and in Microplots.
The response of the peach scion cultivars, Jerseyqueen, Redhaven, Compact Redhaven, and Rio Oso Gem and rootstocks 'Lovely and 'Nemaguard' to inoculation with Meloidogyne incognita was compared in vitro and in microplots. One or more parameters monitored in vitro correlated with at least one parameter monitored in microplots, 4 years after tree planting (1989). A range of responses was observed...
A three-dimensional model of radiative transfer and leaf gas exchange was used to quantify daily carbon (C) assimilation of all fruit-bearing shoots (FBS) in an early maturing 6-year-old peach tree (Prunus persica L. Batsch) with a heavy crop load. For a sample of FBS (n=36), growth of fruit and leafy shoots was measured every 1-2 weeks from 24 days after bloom (DAB) until harvest, between 93-1...
We report the complete genome sequence of Borrelia persica, the causative agent of tick-borne relapsing fever borreliosis on the Asian continent. Its genome of 1,784,979 bp contains 1,850 open reading frames, three ribosomal RNAs, and 32 tRNAs. One clustered regularly interspaced short palindromic repeat (CRISPR) was detected.
