In the micropropagation of difficult-to-root plants, low rates rooting cause high economic losses. The local apple (Malus domestica Borkh.) cultivar #67, which is highly resistant to fire blight disease, has been shown have success. Nanoparticles loaded with auxins could increase success their physicochemical properties. To percentage, effects zinc oxide nanoparticles (nZnO), nZnO indole-3-acet...
Satureja bachtiarica L, an important medicinal plant from Lamiaceae family is valuable because of its medical compounds. Optimization of in vitro culture through callogenesis is proposed to be an alternative for vegetative propagation. In present study, an efficient protocol has been developed for callus induction of S. bachtiarica using different explants and concentrations of plant growth reg...
the aim of this research was to improve quality and vase life of cut gladiolus flowers. the investigation was done with the effects of different concentrations of essential oil of thymol and zataria oil (50 and 100 mg l-1) and silver nanoparticles (3 and 5 mg l-1) and 8-hydroxyquinolin sulfate (300 and 400 mg l-1) with sucrose 3%. in addition, distilled water, ethanol 500 mgl-1 and sucrose 3% w...
شاهدانه ایرانی (Cannabis sativa L.) گیاهی دارویی متعلق به خانواده Cannabinaceae است که ترکیبهای متنوعی از متابولیتهای ثانویه را تولید میکند. این تحقیق بهمنظور بهینهسازی باززایی مستقیم و غیرمستقیم این گیاه در شرایط in vitro انجام شد. ریزنمونههای برگ و هیپوکوتیل از گیاهچههای استریل جداسازی شده و محیط کشتهای حاوی BA (1/0، 2/0، 5/0، 1، 2، 3 میلیگرم در لیتر) به تنهایی یا در ترکیب با 5/0 میل...
جاتروفا Jatropha curcas L.)) گیاهی متعلق به خانواده فرفیون است که از نظر اقتصادی و دارویی اهمیت فراوانی دارد. در بذر این گیاه مقادیر فراونی روغن وجود دارد. تکثیر این گیاه با بذر به علت جوانهزنی اندک چندان مورد توجه نمی باشد. هدف از این تحقیق بهینهسازی کشت بافت گیاه جاتروفا به منظور کالوسزایی و تکثیر گیاه به طریق ریزازدیادی است. آزمایش در قالب طرح خرد شده- عاملی در بلوکهای تصادفی در 9 تکرار ...
While the levels of free auxins in maize (Zea mays L.) roots during arbuscular mycorrhiza formation have been previously described in detail, conjugates of indole-3-acetic acid (IAA) and indole-3-butyric acid (IBA) with amino acids and sugars were neglected. In this study, we have therefore determined free, ester and amide bound auxins in roots of maize inoculated with Glomus intraradices durin...
The water quality, rate of energy transformation, chemical composition of producers and flow of chemical energy were studied in both feeding river Yamuna and Alwar jheel near Allahabad. As the river Yamuna had high value of alkalinity (210.0 mgl(-1)), conductance (518.0 micromhos), dissolved solids (260.0 mgl(-1)), hardness (162.0 mgl(-1)) and chloride (54.6 mgl(-1)) jheel also showed high valu...
orchids are one of the most popular plants in the world and among them phalaenopsis genus have the most sales in a global market. because of its hard propagation, micropropagation technique has been employed recently. in this study, we tried to find out useful protocol for commercial production through in vitro culture. at first, for seed capsules production, flowers were pollinated with hand i...
abstract an investigation was performed in a commercial orchard in shiraz to study the effect of time of application of cuso4 and streptomycin on quality and seedlessness of grapevine (vitis vinifera l. cv. ‘siyah-e-shiraz’). the experiment was conducted as completely randomized block design with 3 replications. plants were treated with 25 mgl-1 cuso4. 5h2o and 200mgl-1 streptomycin 2,4 and 6 d...
The objective of this study was to investigate the propensity of permethrin (PTN) to induce oxidative stress and changes in enzyme activities in liver of rainbow trout and its possible attenuation by vitamin C. Forty-eight fish were randomly assigned to 1 of 6 treatment groups and their livers were used for liver perfusion method: control (0 μgL-1 permethrin and 0 mgL-1 vitamin C), PTN-0.16 (0....
