The evaluation of varieties for a particular region is an important process in order to screen the potential cultivars any specific or climate. Although may express unique behaviour under certain area, but it fail sustain that peculiar character when grown different location. Along with varieties, planting time significantly affect crop production. Therefore, standardization very get good growt...

the postharvest vase life of cut roses was studied to determine the effects of various physiological factors that influence the vase life of cut flower. cut roses were obtained from commercial area of siliguri. to assess the effect of preservatives on the postharvest life of rose, cut flowers were treated with following preservative solutions: fixed amount of citric acid (ca) (300 mg/ml) and 8-...

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...

BACKGROUND AND AIMS Late-acting self-incompatibility (LSI), in which selfed flowers fail to form fruits despite apparently successful growth of the pollen tubes to the ovules, is a contentious and still poorly understood phenomenon. Some studies have indicated pollen tube-pistil interactions, and major gene control. Others favour an early acting inbreeding depression explanation. METHODS Expe...

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...
