Festuca arundinacea

Methods for isolation of perloline from this species (tall fescue) have been refined. Perloline appears not to exhibit antibiotic activity but shows marginal anti-tumour properties. A fluorometric analytical method for this alkaloid has been developed.  

Putrescine, cadaverine, spermidine, spermine, agmatine, and homoagmatine have been isolated. The latter two are guanidoamine derivatives.

Our research on allelopathy in tall fescue (Festuca arundinacea Schreb.) was begun to determine if growth inhibitors were present, if tall fescue had an inhibitory effect on plants growing in association with it, and finally to identify the chemicals responsible for inhibition.

An important route of plant contamination comes from direct contact during surface application of sludge. A study by Chaney and Lloyd [42] showed that sludge constituted 30% of forage dry matter immediately following spray application of liquid sludge on tall fescue (Festuca arundinacea Schreb). The sludge concentration decreased to 10% after 30 days.

Differences in lignification of forage crops were examined in terms of genetic, biosynthetic and environmental factors. This was achieved by comparison of brittle ecotypes of fescue (Festuca arundinacea), and brown-midrib (b.m.3)-mutants of maize (Zea mays) with the corresponding normal plants. For each plant type,... 

Firstly, we studied possible relationships between lignin variation and brittleness of plant organs, using two ecotypes of tall fescue grass (Festuca arundinacea Schreb). Thus, both normal fescue and a brittle ecotype (discovered by Jadas-Hecart (27)), characterized by a brittleness of leaves, sheath and stem, were compared. Possible environmental effects on the biochemistry of lignin formation were estimated by comparison of several parallel crops from two locations. 

Applebee et al. (1999) found that the toxicity of tall fescue (Festuca arundinacea) infected with Neotyphodium coenophialum increased at elevated concentrations of C02 in the atmosphere. In a bioassay study conducted in sterile sand, Sutherland et al. (1999) applied aqueous extracts from ryegrass to potted clover seedlings. Extracts...

Uptake of B is species dependent. Greenhouse pot experiments were conducted to study B uptake by different plant species, Brassica juncea (L.) Czern (wild brown mustard), Festuca arundinacea Schreb. L. (tall fescue), and Brassica napus (canola) (Banuelos et al., 1993). Results showed that the greatest total amount of above ground biomass and below surface biomass was produced by tall fescue and the highest concentrations of tissue B were from roots of tall fescue. A correlation for B and Ca has been reported by Dixon et al. (1973), where B sprays have been shown to increase Ca transport into apples ( Malus spp.).

The structure (25) has been deduced for both loline, an alkaloid of Lolium cuneatum Nevski, ° and festucine, a constituent of Festuca arundinacea Schreb. The identity of loline and festucine has now been confirmed by direct comparison.
