Abstract Gloriosa superba L. is a recently introduced tropical species in Argentina, cultivated as cut flower. It extremely important to know the nutritional demands of crop provide optimal amounts nutrients at each stage, achieving quality and good yield flowers, reducing production costs environmental impact. The objective this work was determine dynamics nutrient absorption cultivation G. fo...

the effects of salicylic acid (sa) and putrescine (put), on cut narcissus was studied. sa (0, 100 and 200 mg l-1) and put (0, 150 and 300 mg l-1), their combinations were tested as preservative mixture. this study was conducted in a factorial experiment with complete randomized design on 108 narcissus cut flowers in horticulture laboratory of agriculture faculty of islamic azad university, jiro...

The main object of this study is to investigate the effect of plant growth regulators on the prolongation of vase life of two kinds of cut carnation under normal and ethylene. Carnation is one of the most popular flowers that has a short life due to its sensitivity to ethylene. Also, the effect of plant growth regulators on several physiological traits under ethylene stress and normal condition...

In this work, the effect of ethylene on flower opening of cut rose (Rosa hybrida) cv. Samantha was studied. However, although ethylene hastened the process of flower opening, 1-MCP (1-methylcyclopropene), an ethylene action inhibitor, impeded it. Ethylene promoted ethylene production in petals, but 1-MCP did not inhibit this process. Of the four ethylene biosynthetic genes tested, Rh-ACS1 and R...

Nanosilver of nanometer-sized silver (Ag+) particles (2-5 nm diam) are used in various applications as an anti-microbial. Boric acid (H3BO3) is water soluble (pH=7). Boric acid is ethylene synthese inhibitor and reduce ethylene production through reducing the ACC synthase and ACC oxidase delays senescence of flower. In this study of different concentrations of boric acid and nano-silver was eva...

The Dutch flower auctions have play a critical role in the world cut-flower industry by providing efficient centers for price determination and transactions of flowers between buyers and sellers. These auctions owned by by Dutch cut-flower grower cooperatives have traditionally used the "Dutch auction" as the mechanism for price determination. This paper considers how changing patterns of inter...

the effects of salicylic acid (sa) and putrescine (put), on cut gladioluswas studied. sa (0, 150, 300 and 450 mg l-1) and put (0, 100, 200 and 300 mg l-1), their combinations were tested as preservative mixture. this study was conducted in a factorial experiment with complete randomized design on 192 gladioluscut flowers in horticulture laboratory of agriculture faculty of islamic azad universi...

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...
