The effects of sodium chloride (NaCl) salinity (control; canal water with 0.4 dS m-1), 2.5 dSm-1, 5.0 dS m-1, 7.5 dS m-1 and 10.0 dS m-1, respectively) developed after 6 weeks of pruning (beginning of study) on plant growth, flowering and quality of three cut rose (Rosa hybrida L.) cultivars viz. ‘Kardinal’, ‘Angelique’ and ‘Gold Medal’ were studied to achieve better management, quality product...

People tend to judge what is typical as also good and appropriate-as what ought to be. What accounts for the prevalence of these judgments, given that their validity is at best uncertain? We hypothesized that the tendency to reason from "is" to "ought" is due in part to a systematic bias in people's (nonmoral) explanations, whereby regularities (e.g., giving roses on Valentine's Day) are explai...

Cut roses are highly valuable ornamentals and their profitability depends on the flower postharvest performance. Bent neck symptoms in make them unmarketable typically related to physiological disorders, bacteria accumulation vase solution, Botrytis cinerea infection. Unusual bent were observed 4.7% of ‘Orange Crush’ from two commercial shipments, resulting complete collapse. This research was ...

OBJECTIVE To quantify the consumption of chocolates in a hospital ward environment. DESIGN Multicentre, prospective, covert observational study. SETTING Four wards at three hospitals (where the authors worked) within the United Kingdom. PARTICIPANTS Boxes of Quality Street (Nestlé) and Roses (Cadbury) on the ward and anyone eating these chocolates. INTERVENTION Observers covertly placed...

Abstract In order to detect phytoncide or aroma in a natural environment using an odor sensor of quartz crystal resonator (QCR), the authors investigated the most suitable drying agent to eliminate moisture influences. The odor sensor used is a system of QCRs coated with organic sensory films. It was experimentally found that calcium chloride is the most suitable desiccant for odor sensing to e...

Rosa hybrida L. is an important commercial cut flower. Salicylic acid (SA) and calcium chloride (CaCl2) act as endogenous signal molecules responsible for growth parameters in plants. The aim of this study was to evaluate the effects of preharvest SA and CaCl2 treatments in extending the vase life of cut rose flowers. Therefore, a factorial experiment based on completely randomized design with ...

To evaluate the effect of nanosilver (5, 10 and 20 mg l-1), hydrogen peroxide (200, 400 and 600 µM) and Nanosil (200, 400 and 600 µM) as antimicrobial compounds in vase solution of cut rose cv. ‘Grand Press Angela’ flowers, an experiment with 10 treatments and 3 replications was conducted in a completely randomized design. Cut rose flowers were continuously treated with these compounds. The res...

Rose (Rosa hybrida L.) plants grown for cut-flower production in greenhouses produce flowers in flushes year-round. Crop models for this system must handle the cyclical nature of productivity, which is determined by the horticultural production methods. Nutrition was not accounted for in previous rose growth models, since little is known about uptake of the essential nutrients by rose roots. Th...
