The most rapid species radiations have been reported from 'evolutionary laboratories', such as the Andes and the Cape of South Africa, leading to the prevailing view that diversification elsewhere has not been as dramatic. However, few studies have explicitly assessed rates of diversification in northern regions such as Europe. Here, we show that carnations (Dianthus, Caryophyllaceae), a well-k...

PIXE (Proton Induced X-ray Emission) is a well-known method for elemental analyses of specimens in applied studies. In this paper, we report results of an application of PIXE in trace-element analysis of normal and vitrified carnations in vitro culture. Experiments were performed to study the vitrification in connection with the trace elements in carnation tissues. About two hundred PIXE spectr...

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...

CURRENT SCIENCE, VOL. 88, NO. 4, 25 FEBRUARY 2005 594 The nucleotide sequence data here have been submitted in the EMBL nucleotide database under the accession numbers AJ549954 (CP), AJ584842 (P7) and AJ584843 (P9).

Bacillus species are widely exploited as biocontrol agents because of their efficiency in impeding various plant pathogens with multifaceted approach. In this study, Bacillus species were isolated from rhizosphere of various plants viz., carnations, cotton, turmeric, and bananas in Tamil Nadu state of India. Their potential to control the mycelial growth of Sclerotinia sclerotiorum was assessed...
