this study performed to evaluate genetic diversity of some wild and domesticated (unknown foreign cultivars) blackberries in sanru collection based on morphological traits. results showed high diversity for flowering, ripening time and fruit juice. wild genotypes showed significant differences in leaf, flower, thorn number, fruits and seed fresh weight compared to domesticated cultivars. based ...
plant spacing and nitrogen are the most important factors for increasing tuberose quality and quantity. in this study, field experiment carried out as factorial randomized completely block design (rcbd) in 3 replications. different levels of nitrogen (0, 50, 100, 150, 200, 250 kg/ha) of ammonium nitrate was used. second factor was different plant spaces (10, 15, 20 and 25 cm). results showed th...
This research was performed to investigate the effect of different substrates and humic acid on quantitative and qualitative traits of cut Rose (Rosa hybrida cv. Angelina) in soilless culture. A factorial experiment was carried out in a randomized complete blocks design with three replications. The first factor was humic acid (HA) at 4 concentrations (0, 2, 4 and 6 gr/L) and the second factor w...
aim: evidence indicates that demographic factors such as age, gender, and mother's literacy are important predictors of fruit and vegetable consumption among adolescents. so, this study was conducted in order to survey the relation between socio-demographic factors and fruit and vegetable consumption among tehranian adolescents in 2013. methods: this cross-sectional study (descriptive-analytic)...
In order to improve quantitative and qualitative properties and vase life of rose cv. Dolcvita, an experiment was conducted in a randomized complete blocks design with ten treatments and three replications in a hydroponic greenhouse adjacent to Yasouj city, Iran. Treatments included control, spermidine (0.5, 1 and 1.5 mM), calcium sulfate (2.5 and 5 mM), spermidine 0.5 mM+ calcium sulfate 2.5 m...
The genus Tribulus belongs to the family Zygophyllaceae comprises approximately 25 species that grow as prostrate. This study will collect terrestris L. and subramanyamii P. Singh, G.S. Giri & V. Singh. analyzed for their macroscopic, microscopic phytochemical properties. Selected plant were collected from three geographical locations in Maharashtra State, India. To confirm quality authenti...
The present study investigates the antioxidant, anticancer, anticholinesterase, anti-genotoxic activities and phenolic contents of flower, fruit and seed methanol extracts of Hypericum retusum AUCHER. The amounts of protocatechuic acid, catechin, caffeic acid and syringic acid in methanol extracts were determined by HPLC. Total phenolic content of H. retusum seed extract was found more than fru...
growth traits, yield and fruit quality in ‘synda’ tomato were compared with those in tomatoes grafted onto either ‘king kong’ rootstock or onto their own rootstocks, (trained as single or double stem), and at two fruit thinning levels, of: no thinning or thinned to five fruits per truss. the data related to crop growth rate (cgr), relative growth rate (rgr), net assimilation rate (nar), leaf ar...
مدل روزنه های موازی موج دار (corrugated oarallel bundle model) برای تعریف اثر ساختمان روزنه ها در نفوذ-واکنش (diffusion and reaction) در کاتالیستهای متخلخل بکار می رود. در مدل روزنه های موج دار، از یک دسته روزنه های اصلی (pore) استفاده شده است . هر یک از این روزنه های اصلی دارای یکسری عناصر روزنه می باشد که هر عنصر دارای یک شعاع تعیین شده به صورت اتفاقی از یک توزیع اندازه روزنه ها (pore size di...
