Eleven strains of pink-pigmented bacteria, isolated from the leaf surface of Loliumperenne (perennial rye grass), were compared with six marker strains and 50 pink-pigmented isolates from a variety of habitats. The organisms were examined for 146 unit characters, and the data were analyzed by the simple matching and Jaccard coefficients and the average-linkage algorithm. The Lolium strains form...

The establishment of temporary meadows is not a new problem, but it has been the subject long researches. When achieving this objective, mixture perennial species must be taken into account that corresponds from point view pedo-climatic zone, technical and economic possibilities, purpose duration designed. (Vidican Roxana al. 2002). Our research shows complex mixtures (grasses legumes) are most...

Water shortage worldwide mandates minimum use of irrigation water with maximumefficiency and productivity in all agricultural crops, landscape plants and turf. The objective inthis experiment was to study the effect of two levels of evapotranspiration-based (ETc) droughtin combination with two levels of nanosilicon dioxide (SiO2; NanSi1=1 mM and NanSi=2 mM),two levels of digoxin (Dig1=0.25 mg.l...

In predicting wheat (Triticum aestivum L.) phenology, logic suggests that basing thermal unit accumulation on near-surface soil temperature should give a better representation of shoot apex thermal unit accumulation than air temperature until internode elongation raises the apex above the soil surface. A study was undertaken to determine if predictions of winter wheat phenology are improved whe...
