A method for the extraction of valuable compounds from plants and flowers (viz. laurel, rosemary, thyme, oregano and tuberose) is proposed. The dynamic approach allows go-and-backward circulation of the extractant (ethanol) through the solid sample subjected to the action of an ultrasound probe (thus reducing sample amount and avoiding overpressure). A multivariate optimisation study and applic...

Tuberose (Polianthes tuberosa L.) is one of the most important cut flowers in Iran. This research was conducted to investigate the effects of spraying a mixture of amino acids on the physiological and morphological characteristics of tuberose. The experiment was carried out in two successive years (2009 and 2010) using two tuberose cultivars ‘Dezfuli’ and ‘Mahallati’. The experiment was arrange...

The study identified agronomic practices, analyzed relative profitability, and resource use efficiency of tuberose cultivation in Bangladesh during January 2010. Primary data were collected from 100 randomly selected farmers from Jessore and Chuadanga districts. The results revealed that the per hectare costs of tuberose cultivation were estimated at Tk. 2,00,761 and Tk. 1,29,283 over full cost...

Two popular cultivars of tuberose (Agave amica (Medik.) Theide and Govaerts syn. Polianthes tuberosa L.) from the family Asparagaceae, widely cultivated for floricultural purposes are ,'Calcutta Single' (CS) 'Calcutta Double' (CD). It was evidenced that CS flowers emit intense scent volatiles as compared to CD flowers, while retained higher contents internal pool than flowers. Such contrasting ...

Tuberose (Polianthes tuberosa) is one of the most important cut flowers with fragrant buds. To prolong vase life of tuberose, proper preservative solution applying is necessary. For this purpose, two types of chemical and natural treatments were used. Applied treatments were benzyladenine (50, 100, and 150 mg l-1), the extracts of rosemary and Eucalyptus (12, 25 and 50%) and sour orange fruit e...

tuberose (polianthus tuberosa) is a commercially important cut flower; but its longevity and quality characteristics are compromised by stress during storage and transportation. thus, it is important to determine the most appropriate preservative solution to best maintained cut flowers. tests were done to examine the effects on of nano-silver (ns) (0, 15, 30 and 45 mg l-1) and sucrose (0, 4 and...

abstract tuberose is one of the most important cut flowers in iran and the world. in this experiment, effect of microelements fe, zn, cu and mn on inflorescence length, inflorescence bunch length, number and diameter of floret, diameter of inflorescence bunch and vase life of tuberose flowers were studied. this study was based on four separate completely randomized experimental design with four...
