ranunculus ternatus/概念

From 1999 to 2002, we studied the yield production and quality parameters of grassland installed on sandy soils (1) under normal management (NM), (2) under management with respect to meadow birds (MBM) -first mowing date 15 June or later- and (3) under botanical management (BM) -first mowing date 1

The combined impacts of simulated increased nitrogen (N) deposition (75 kg Nha(-1)yr (-1)) and increasing background ozone (O(3)) were studied using two mesotrophic grassland species (Dactylis glomerata and Ranunculus acris) in solardomes, by means of eight O(3) treatments ranging from 15.5 ppb to

Progamic processes are particularly temperature-sensitive and, in lowland plants, are usually drastically reduced below 10 °C and above 30 °C. Little is known about how effectively sexual processes of mountain plants function under the large temperature fluctuations at higher altitudes. The present
