The relationship between phosphorus (P) uptake and growth rate of chrysanthemum plants grown hydroponically for cut flowers was investigated. In Exp. 1, fresh weight increase of chrysanthemum cv. Seiun plants at flower budding phase administered 0 to 40 ppm in culture solution for 16 days was evaluated. 1. P uptake by the chrysanthemum plants was nearly proportionate to P concentration in the c...

Phytochemical investigation of Tanacetum parthenium L. family Asteraceae cultivated in Egypt resulted in isolation and identification of four flavonoids. One surface flavonoid was isolated from the fresh leaves and three other flavonoids were isolated from the flower heads. Four sesquiterpene lactones were isolated from the leaves. Two sterols were isolated from the roots. A comparative study o...

A flavonol, kaempferol, isolated from the fresh flower petals of C. sativus L. (Iridaceae) as the sole component. The structure of the compound was determined by chemical and spectroscopic methods.

Flower-like AgCl microstructures with enhanced visible light-driven photocatalysis are synthesized by a facile one-pot hydrothermal process for the first time. The evolution process of AgCl from dendritic structures to flower-like octagonal microstructures is investigated quantitatively. Furthermore, the flower-like AgCl microstructures exhibit enhanced ability of visible light-assisted photoca...

intercropping systems lead to reduce weeds population and their biomass. in order to study effect of marigold (calendula officinalis) and mungbean (vigna radiata) intercropping in different sowing times on yield and weeds control a factorial experiment based on randomized complete block design was performed in islamic azad university, tabriz branch, iran, during 2012 in three replications. stud...

abstract for evaluation and identification some of the chamomile species in two genera anthemis and matricaria, morphological and phonological characteristics were used. the experiment was conducted in a randomized completely blocks design (rcbd) with three replicates, sixteen quantitative and qualitative traits were evaluated such as plant height, anthodium diameter, receptacle diameter, ligul...

this study was performed to assess the effects of nitrogen fertilizer and vermicompost on qualitative and quantitative yield of chamomile ( matricaria chamomilla l.). it was conducted at the research fields of ran company located in firouzkouh, iran, in 2013. treatments were consisted of 1) control, 2) 100% nitrogen from urea, 3) 100% nitrogen from ammonium nitrate, 4) 75% nitrogen from urea an...

Objective: Chamomile is one of the commercial medicinal plants produced in Ethiopia. Besides, it is priority crop in national aromatic and medicinal plants research project in the country. As chamomile production affected by production techniques this activity was conducted to identify the effect of seed storage duration and seedling raising methods on its seedling establishmen...

The aim of this study was the better assessment of the relationship of pulsing treatment of gibberellic acid as an anti-senescence agent and holding in sucrose as a carbohydrate supply resource on improving some qualitative and physiological attributes of cut rose flower cv. Velvet. Hence, an experiment involving the pulsing treatment with gibberllic acid (GA3) at 0, 20, 40 and 60 mg L-1, for 2...
