gerbera cut flowers is one of the important and popular cut flowers in the world that regardless of increasing production of this plant in iran, the duration of its life is short due to rapid wilting petals and bending neck of flower. to increase vase life of gerbera cut flowers cv. ‘alain ducasse’, the essences of eucalyptus and rosa damascena, the combination of these two essences at a concen...

Lisianthus (Eustoma grandiflorum cv. ‘Mriachii Blue’) is one of the most important and marketable cut flowers in the world. However, a relatively limited vase life reduces its marketability. The aim of the present study was to evaluate the effects of essential oils in extending vase life of cut flowers of Lisianthus. For this purpose a factorial experiment based on a completely randomized desig...

the abscission of alstroemeria petals is the serious problem at the industry of cut flowers of this plant. in this study, cut alstroemeria cv. bridal flowers were pulsed with solutions containing natural essential oil carvacrol, gibberellic acid and benzyladenine (50 and 100 mg l-1), -5-sulfosalicylic acid (1 and 1.5 mm) and sucrose (5 and 10%) for 24 hours. the distilled water was used as cont...

The effect of leaf extracts of Psidium guajava and Piper betle on prolonging vase life of cut carnation flowers was studied. "Carola" and "Pallas Orange" carnation flowers, at bud stage, were pulsed 24 hours with a floral preservative. Then, flowers were placed in a vase solution containing sprite and a "germicide" (leaf extracts of P. guajava and P. betle, 8-HQC, or a copper coin). Flowers tre...

in this study, gerbera ( cv. alain ducasse ) cut flowers were treated with essences of eucalyptus and rosa damascena at a concentration of 200 mg l -1 and their effects on the vase life of flowers and some qualitative characteristics were evaluated. this research was a completely randomized design with factorial arrangement. maximum vase life was obtained for flowers treated with the eucalyptus...

Australian crab spiders Thomisus spectabilis ambush pollinating insects, such as honeybees (Apis mellifera) on flowers, and can change their body colour between yellow and white. It is traditionally assumed that the spiders change their colour to match the flower colour, thus rendering them cryptic to insect prey. Here, we test this assumption combining state-of-the-art knowledge of bee vision ...
