Plant Growth Inhibition

Two new isomeric metabolites, toxins A and B, were isolated from culture extracts of Penicillium islandicum. Both toxins had a molecular formula of C16H15O2N2Cl, and physical and chemical analyses indicated that they were indole alkaloids. LD50 of toxin A was about 75–125 mg/kg in day-old cockerels. Insufficient toxin B was available to determine accurate LD50 values. Toxin A moderately inhibited growth of wheat coleoptiles but did not inhibit growth of week-old intact corn and bean plants. Toxin B showed no plant-growth inhibition.

Abstract The list of species of the plant parasitic nematodes presented in this paper (133 species belonging to 14 families) is based on the results of faunistic research conducted in the Wielkopolska region by Polish nematologists up until the year 2010, and the results obtained from the project “Elaboration of Innovative Methods for Rapid Identification of Nematodes Causing Damage to the Economy” managed by the Museum and Institute of Zoology of the Polish Academy of Sciences. During the two years of the project (2010-2011) we found 21 species of nematodes which had not yet been reported in the list of species from the Wielkopolska region. Two of them were reported for the first time in Poland.
