shoot tips from actively growing, greenhouse maintained plants of kalanchoe blossfeldiana were cultured in vitro for shoot proliferation and root initiation on murashige and skoog (ms) basal medium supplemented with naa and ba, both in concentrations of 0.00, 0.50, 1.00 and 2.00 mg l-1. results showed that the maximum plantlets height (7.012 cm), node number (4.516), root number (8.860) and roo...
Crown roots constitute the majority of the rice (Oryza sativa) root system and play an important role in rice growth and development. However, the molecular mechanism of crown root formation in rice is not well understood. Here, we characterized a rice dominant mutant, root enhancer1 (ren1-D), which was observed to exhibit a more robust root system, increased crown root number, and reduced plan...
Knowledge of the location and magnitude of the resistance to water flow in a plant is fundamental for describing whole plant response to water stress. The reported magnitudes of these resistances vary widely, principally because of the difficulty of measuring water potential within the plant. A number of interrelated experiments are described in which the water potential of a covered, nontransp...
The effects of different concentrations of Zinc oxide nano particles (ZnONP; 0, 10, 25, 50, 75 and 100 mg L-1) and Humic acid (HA; 0, 50, 100, 500 and 1000 mg L-1) on root length and number, leaf length and number, bulb diameter, and chlorophyll, total phenol, anthocyanin and flavonoid contents were examined under in vitro conditions. Total phenol, flavonoid and anthocyanin contents were signif...
در قسمت اول رساله واکنش تشکیل کمپلکس یون تالیم با calix[4]crown-6 و سه مشتق دیگر آن با روشهای 203tl , 1h nmr مورد بررسی قرار گرفتند. همچنین کمپلکس یک هسته ای tlclo4 و 1,3-calix[4]bis-o-benzo-crown-6 در حالت جامد تهیه شد و ساختار بلوری x-ray آن تعیین گردید. سینتیک و مکانیسم تفکیک و تغییرات پیکربندی کمپلکس تالیم و calix[4]crown-6 با دینامیک 1h nmr مورد مطالعه قرار گرفت. یک منحنی محدب آرنیوس برای ...
To investigate the effect of manganese (Mn) and salinity on some growth traits and chemical composition of pistachio (Pistacia vera L.) seedlings, a factorial experiment was carried out with two factors of salinity (0, 75, 150, 225 and 300 mM NaCl) and Mn (0, 12, 24 and 36 µM Mn from MnSO4 source) as completely randomized design with four replicates, in greenhouse in perlite medium. Results sho...
