phenological modifications in plants by various edaphic factors.various mechanical, chemical and physical soil analyses were carried out, in addition to weather observations, for 3 years at several sites along an oceanic-continental gradient in a fjord district in western norway. all the environmental factors observed were correlated with the spring and a few late-season phenophases of many native and cultivated woody plants and some herbs by simple, linear correlations and by stepwise multiple and partial analyses. different techniques were used to try and ...200111769320
the main allergen of olea europaea (ole e i) is also present in other species of the oleaceae family.three major pollen allergens from fraxinus excelsior, ligustrum vulgare and syringa vulgaris belonging to the oleaceae family were purified. monoclonal antibodies previously raised against the main allergen of olea europaea (ole e i) were used for their purification by affinity chromatography. the three new purified allergens were able to bind human ige from serum of olive-allergic patients in a way analogous to ole e i. crossed radioimmunoelectrophoresis of the four allergens, using anti-olive ...19938319129
role of auxin and sucrose in the differentiation of sieve and tracheary elements in plant tissue cultures.the differentiation of sieve and tracheary elements was studied in callus culture of daucus carota l., syringa vulgaris l., glycine max (l.) merr., helianthus annuus l., hibiscus cannabinus l. and pisum sativum l. by the lacmoid clearing technique it was found that development of the phloem commenced before that of the xylem. in not one of the calluses was differentiation of tracheary elements observed in the absence of sieve elements. the influence of indole-3-acetic acid (iaa) and sucrose was ...198024306691
floral to green: mating switches moth olfactory coding and preference.mating induces profound physiological changes in a wide range of insects, leading to behavioural adjustments to match the internal state of the animal. here, we show for the first time, to our knowledge, that a noctuid moth switches its olfactory response from food to egg-laying cues following mating. unmated females of the cotton leafworm (spodoptera littoralis) are strongly attracted to lilac flowers (syringa vulgaris). after mating, attraction to floral odour is abolished and the females fly ...201222319127
phenological observations on shrubs to predict weed emergence in turf.phenology is the study of periodic biological events. if we can find easily recognizable events in common plants that precede or coincide with weed emergences, these plants could be used as indicators. weed seedlings are usually difficult to detect in turf, so the use of phenological indicators may provide an alternative approach to predict the time when a weed appears and consequently guide management decisions. a study was undertaken to determine whether the phenological phases of some plants ...200515846520
