Exposure of carnation (Dianthus caryophyllus L.) flowers to ethylene evokes the developmental program of petal senescence. The temporal relationship of several aspects of this developmental program following treatment with ethylene was investigated. Exposure of mature, presenescent flowers to 7.5 microliters per liter ethylene for at least 6 hours induced petal in-rolling and premature senescen...

The main aim of this study was to evaluate the effects of silicon (Si), ethanol (Et), ascorbic acid (AA) and citric acid (CA) on vase life of Narcissus tazetta L. cv. ‘Shahla’cut flowers. For this purpose, an experiment based on completely randomized design was conducted with Si (5, 10 and 20 mM), Et (2 and 4%), AA (100, 200 and 300 mg L-1), CA (100, 200 and 300 mg L-1) and control (distillated...

BACKGROUND Research on the potentially adverse effects of occupational pesticide exposure on risk of spontaneous abortion (SAB) is limited, particularly among female agricultural workers residing in developing countries. METHODS Reproductive histories were obtained from 217 Ecuadorian mothers participating in a study focusing on occupational pesticide exposure and children's neurobehavioral d...

In tissue culture, high production cost of the products restricts their reach. Though tissue culture is a major strength in floriculture it is marred by pricing issues. Hence, we developed a complete regeneration low cost micropropagation protocol for an economically important floriculture crop, carnation (Dianthus caryophyllus L.). Successful regeneration of carnation from nodal explants on co...
