Silicon (Si) is one of the beneficial elements for plants, which improves quantity and quality of yield, decreases evaporation and transpiration and enhances plant resistance to abiotic stresses. In order to evaluate the effect of Si and nano-silicon (N-Si) on growth, morphological and photosynthesis attributes of tomato, cultivar Falcato, an experiment was carried out in a hydroponic system, ...
in this thesis, phosphorus ylides [phbppy], [no2bppy] and [brbppy] have been synthesized through the formation of phosphonium salt and dihydrogenation, followed by the reaction of pd(oac)2 and the orthopalladated dinuclear complexes [pd(?-cl)(phbppy)]2, [pd(?-cl)(no2bppy)]2 and [pd(?-cl)(brbppy)]2 have been produced. the reaction of dinuclear complexes and bidentate ligands [l = bipy (2,2-bipyr...
Regarding the differences between shoot and root optimum growth temperature and the impress of temperature on root function specially nutrient absorption this study was aimed to investigate the effect of low root temperature with three nitrogen levels in lettuce. The experiment was conducted in factorial completely randomized trial design with five replication. Treatments were used including th...
In this study, three phenolic compounds were isolated from the seeds of Zizyphus spina-christi for the first time. The compounds were identified by means of 1 H-NMR-, UV and GC-MS as p-hydroxybenzoic acid, kaempferol, quercetin-3-O--L-rhamnosyl--D-glucopyranoside (rutin).
اثر بازدارندگی نفت خام بر عملکرد رویشی و فیزیولوژیکی بذر و نهال گونه‌های کنار، کهور، آکاسیا و اقاقیا
In this study the effect of crude oil (0 to 20% w/w), one of the main pollutants of current age, on physiological characteristics of Prosopis juliflora, Acacia victoria, Ziziphus spina-chrisi and Robinia pseudoacacia in seed and seedling stages based on a completely randomized design with 10 replications in each experimental unit has been studied. The results revealed that germination rate of P...
This paper analyzes Martin Luther’s criticism of increasingly corrupt church practices, including, the papacy’s granting of indulgences, the promotion of pilgrimage, the preservation and exploitation of relics, the cult of saints, and the belief in saintly intercession. I will examine how Luther’s critiques of these practices were expressed in the religious propaganda that circulated during thi...
Beneficial effect of titanium on plant growth, photosynthesis and nutrient trait of tomato cv. Foria
ABSTRACT- Titanium is a beneficial element for plant since its promotive effect on plant metabolism has been well documented. However, the physiological role of this trace element in tomato is not clear. This experiment was conducted as a complete randomized design to study two concentrations of titanium (1 and 2 mg/L Ti) and 0 as control on physiological and nutrient properties of tomato cv. F...
This study was carried out to determine effects of different durations (20, 40, 60 days and control) of cold stratification treatments on seed germination and to overcome dormancy in seeds of twelve different drought tolerant plants. The species used in this study were Arbutus andrachne L., Cistus creticus L., Colutea armena Bois. Huet., Cotinus coggygria Scop., Cotoneaster numullaria Fisch. an...
در حال حاضر ترکیبات با منشاء طبیعی با ارائه فعالیت های بیولوژیکی و دارویی مطلوب به عنوان عوامل شیمی درمانی مورد توجه قرار گرفته اند. در این میان گیاهان دارویی در طول تاریخ با استفاده از توانایی خود در تولید متابولیت های ثانویه در درمان بیماری ها از جمله سرطان استفاده می شوند. گیاه ziziphus spina christi از خانواده rhamnaceae استفاده فراوانی برای درمان طیف گسترده ای از بیماری ها دارد. هر چند از ...
