The main aim of this study was to evaluate the effects of silicon (Si), ethanol (Et), ascorbic acid (AA) and citric acid (CA) on vase life of Narcissus tazetta L. cv. ‘Shahla’cut flowers. For this purpose, an experiment based on completely randomized design was conducted with Si (5, 10 and 20 mM), Et (2 and 4%), AA (100, 200 and 300 mg L-1), CA (100, 200 and 300 mg L-1) and control (distillated...

to study the effect of sucrose and calcium chloride on the quality and longevity of cut flower of rose cv. varlon, this experiment was conducted at the faculty of agriculture, zanjan university, zanjan, iran, in 2007. cut flowers were received from mahallat ornamental plants and flowers research station. experimental factors included: sucrose at four levels (0, 40, 80 and 100 mg/l) and calcium ...

the objective of the present study was to investigate the effect of different doses of some 7 natural semi-arid medicinal plants’ essential oils on in vitro ruminal digestion and fermentation patterns of a mid-forage (alfalfa hay: concentrates, 1:1) diet. treatments consisted of either basal diet alone (control) or added with 35, 70, 140 or 280 µl l-1 of coriander, oregano, caraway, cumin, cinn...

in this paper by use of mathematical modeling of an observer [14,15] the notion of relative information functional for relative dynamical systemson compact metric spaces is presented. we extract the information function ofan ergodic dynamical system (x,t) from the relative information of t fromthe view point of observer χx, where x denotes the base space of the system.we also generalize the inv...
