The respiration rate (RR) (CO2 production), activation energy (Ea) and Q10 of maleic hydrazide-treated onion bulbs (Allium cepa, cv. Rouge Amposta) at 20.10-6 mol.L-1 (MH1) and 45.10 -6 mol.L-1 (MH2) were measured at 4, 10 and 20oC. Immediately after treatment, the Q10 of MH-treated and control bulbs were not significantly different. After 8 weeks of storage, Q10 of control and both MH-treated ...

We recorded three mite species, Pergamasus (Thenargamasus) instatutus Athias-Henriot, 1967, (Pergamasus) laminarius Witaliński, 1971 and Holoparasitus ampullaris 1994, from Slovakia for the first time. Mites of genera Berlese, 1903 Oudemans, 1936 are predatory mites living mainly in a soil rotting organic matter Holarctic region with centre distribution Europe. Till now, P. was Austria Hungary,...

Subsocial, xylophagous cockroaches of the genus Cryptocercus exhibit a disjunct distribution, with representatives in mature montane forests of North America, China, Korea and the Russian Far East. All described species are wingless and dependent on rotting wood for food and shelter at all stages of their life cycle; consequently, their distribution is tied to that of forests and strongly influ...

Quorum sensing (QS) is a population density-dependent regulatory mechanism in which gene expression is coupled to the accumulation of a chemical signaling molecule. QS systems are widespread among the plant soft-rotting bacteria. In Pectobacterium carotovorum, at least two QS systems exist being specified by the nature of chemical signals involved. QS in Pectobacterium carotovorum uses N-acylho...
