The present study deals with the cytological investigations on the meristematic root cells of carnation (Dianthus caryophyllus Linn.) grown in vivo and in vitro. Cellular parameters including the mitotic index (MI), chromosome count, ploidy level (nuclear DNA content), mean cell and nuclear areas, and cell doubling time (Cdt) were determined from the 2 mm root tip segments of this species. The ...

Hyperhydricity is one of the major problems hindering in vitro propagation of Dianthus caryophyllus L. Silicon (Si) is a well-known beneficial element renowned for its stress amelioration properties in plants. This study has demonstrated the physiological and molecular mechanism behind the Si-mediated recovery from hyperhydricity in D. caryophyllus L. 'Green Beauty'. Four weeks old hyperhydric ...

During LEP running in 1995 and 1996, DELPHI accumulated data at centre-of-mass energies ranging from 130 GeV to 172 GeV. Searches were performed for events containing four nal-state fermions in the l + l ? q q, q q and l + l ? l + l ? channels. The number of events detected was found to be consistent with Standard Model predictions.

Os óleos essenciais extraídos de plantas exibem funções ecológicas importantes demonstradas através diversos estudos, com potencial para serem utilizados como agentes antimicrobianos naturais em substituição aos pesticidas convencionais. O objetivo deste estudo foi avaliar in vitro a fungitoxidade do óleo essencial Eugenia caryophyllus Tumb, diferentes concentrações, contra o crescimento miceli...
