Toxic Responses

Investigations were conducted in glass-house and field to determine the effects of pre-emergence applications of certain phenoxyacetates and phenylcarbamates on plant species. The effects of both types of compounds on the establishment of all monocotyledons and dicotyledons tested and on the ear formation and grain yield of a cereal Triticum vulgare, are described. The phenoxyacetates, applied in 0.1 per cent. concentrations, markedly inhibited all the dicotyledonous species. Monocotyledons were, in general, more tolerant than the dicotyledons but were affected at the higher concentrations. The phenylcarbamates produced toxic responses, in varying degrees of intensity, on all the graminaceous species tested but affected only one dicotyledon, viz. Linum usitatissimum. Symptoms of toxicity are described and some factors which appeared to govern their intensity are noted.

AbstractWe investigated early spontaneous colonisation patterns during semi-dry grassland restoration at two sites in SE Austria. The sites were left to regenerate passively without addition of plant propagules on a former arable field and an apple orchard. The sites were prepared only by ploughing (arable field) or clear cutting (apple orchard) and subsequently mowed annually. We studied whether, four years after project initiation, target species from adjacent semi-dry grasslands had established at the restored sites. We asked: 1) Does passive restoration lead to the establishment of target species? 2) Do abiotic parameters or distance to reference sites explain early colonisation patterns? 3) Do plant traits predict the colonisation success of different species? At each site, we collected data in 4 m × 4 m plots, in which we sampled the vegetation, analysed abiotic parameters (soil potassium- and phosphorus-content, soil-pH, slope) and recorded the minimum distance to the reference site. We tested for correlations between abiotic variables, plant traits and colonisation success. Colonisation patterns were not driven by abiotic soil conditions but rather by nearest distance to the reference sites. In addition, the vegetation developed differently in the former arable field and the apple orchard. Competitive species of the Arrhenatherion and thermophilic ruderal associations dominated the early restoration stage at both sites. Passive restoration of semi-dry grasslands on former agricultural land is unlikely to succeed unless complemented by initial ploughing, nutrient stripping and addition of propagules of rare species.

Abstract Sendžikaitė J., Pakalnis R., Gudžinskas Z., 2013: Changes in botanical diversity of sown grasslands due to naturalization and extensive management [Sėtų pievų botaninės įvairovės kaitos dėl žolynų natūralėjimo ir ekstensyvaus naudojimo]. - Bot. Lith., 19(2): 99-110 The paper deals with sown grassland naturalization models related to changes in botanical diversity of extensively managed meadows under temperate climate conditions. The vegetation surveys were carried out in Sėliškės and Polyma Experimental Field Stations (Lithuania). Based on our research data and literature sources (on the investigation of Lithuanian natural meadows), we developed the following hypothetical models of sown grassland naturalization: vascular plant species constancy alteration chronocline, vascular plant species constancy and productivity alteration topocline and a scheme of sown grassland naturalization on hilly landscape. Here we consider extensive management and naturalization as one of most natural and requiring minor investments method for grassland restoration.
