the effect of light and temperature on the growth of two subtropical and two temperate grass species.	the effect of light intensity and temperature on the growth of young plants of two temperate (lolium perenne, festuca arundinacea) and two subtropical (lolium rigidum, bromus unioloides) grass species was studied in the northern part of the gdr under open-air conditions. it was found that the subtropical species reacted highly sensitive to changes in the two environmental factors and showed absolutely higher growth performance during the summer as compared with the temperate species. the multipl ...	1976	985302
the rumen flagellate piromonas communis: its life-history and invasion of plant material in the rumen.	the rumen flagellat piromonas communis is the zoospore of a phycomycete fungus inhabiting the rumen. zoosporogenesis was stimulated by a dietary component (the inducer), and inhibited by compounds affecting membrane structure and function, but not by inhibitors of protein synthesis. the zoospores showed taxis towards the tissues surrounding the inflorescence of lolium perenne l. in the rumen, invading principally the stomata and damaged tissues. the zoospores germinated on this substratum and th ...	1977	16983
on the induction of zoosporogenesis in the rumen phycomycetes neocallimastix frontalis, piromonas communis and sphaeromonas communis.	the plant components inducing zoosporogenesis in the rumen phycomycetes neocallimastix frontalis, sphaeromonas communis and piromonas communis were widely distributed in the plant kingdom with no apparent taxonomic relationship. in lolium perenne l. (perennial rye-grass) and hordeum distichon (barley), the components were principally present in the leaves and aerial tissues. sufficient inducer was present in the normal diet of the host animal to trigger the differentiation and release of the zoo ...	1977	21939
antagonistic interactions of phylloplane bacteria with drechslera dictyoides (drechslera) shoemaker.	strains of listeria denitrificans (e2), pseudomonas fluorescens (c37 and c92), and xanthomonas campestris (d119), isolated from the phylloplane of lolium perenne (s24), were antagonistic to drechslera dictyoides (drechslera) shoemaker. from in vitro and in vivo experiments it was deduced that their mode of activity included an initial inhibition of spore germination, a retardation in the rate of germ-tube elongation, and ultimately lysis of the hyphae. the effects were expressed on the plant in ...	1977	406025
genetic control of resistance to crown rust (puccinia coronato corda) in lolium perenne l. and its implications in breeding.	a genetic analysis of resistance to crown rust in a series of natural populations of lolium perenne by means of the diallel cross has revealed that heritability is high (58%) and that the genes concerned show complete but ambi-directional dominance for resistance. an environmental correlation was established between the degree of infection and productivity but no genetic correlation was present. the implications of this mode of control for resistance breeding procedures are briefly considered.	1977	24317594

ruminococcus flavefaciens cell coat and adhesion to cotton cellulose and to cell walls in leaves of perennial ryegrass (lolium perenne).	ruminococcus flavefaciens was shown to possess a prominent glycoprotein coat, which contained rhamnose, glucose, and galactose as its principal carbohydrates. periodate-reactive carbohydrate occurred as a surface layer of the coat. the ruminococci adhered strongly by means of this coat to cotton cellulose and to cell walls in leaf sections of lolium perenne l. (perennial ryegrass). the coat was diffuse at the point of contact so that the bacterial cell wall was in close contact with the substrat ...	1978	16345261

[immediate hypersensitivity to fruits and vegetables and pollenosis].	various works have been published, mainly by scandinavian authors, in which a partial immunological identity has been found to exist between birch pollen and hazelnut and apple. however, our attention has been particularly drawn to the high proportion of people who are allergic to the apple and other fruits, which in some cases has been as much as 50 and 70%, and in whom an oral pruritus alone is considered sufficient a symptom of allergies to certain foodstuffs. however due to the fact that the ...	1985	4036764
stabilizing effect of epsilon-aminocaproic acid on allergenic extracts.	the effect of epsilon-aminocaproic acid (eaca) on the degradation of an aqueous lolium perenne extract was studied by intracutaneous tests and by rast inhibition. extracts for skin testing stored at 4 degrees c for 12 months and at 37 degrees c for 6 weeks were significantly protected from degradation by addition of 0.1 mol/l of eaca before storage. extracts were stored for rast inhibition at 4 degrees c for 6 months and at 37 degrees c for 7 days. shelf life was twofold to threefold increased w ...	1985	4056242
