Subtropical China harbours the world's most diverse temperate flora, but little is known about the roles of geographical and eco-climatic factors underlying the region's exceptionally high levels of species diversity and endemism. Here we address this key question by investigating the spatio-temporal and ecological processes of divergence within the Dysosma versipellis-pleiantha species complex...

An investigation was made to see the salt tolerance of 10 weed species of rice. Properly dried and treated seeds of weed species were placed on 9 cm diameter petridishes lined with Whatman No. 1 filter paper under 6 salinity regimes, viz. 0 (control), 4, 8, 16, 24 and 32 dS m(-1). The petri dishes were then kept in germinator at 25 +/- 1.0 degrees C and 12 hr light. The number of germinated see...

Soil seedbanks are defined in composition and quantity by many environmental factors inherent to a specific area, they can be an indicator of the potential problems weeds crops. In Valencia (Spain), rice is cultivated with continuous flooding during growing season, after harvesting, paddy fields flooded again winter.

Abstract Since its resurrection, the resinicolous discomycete genus Sarea has been accepted as containing two species, one with black apothecia and pycnidia, orange. We investigate this hypothesis using three ribosomal (nuITS, nuLSU, mtSSU) regions from morphological examination of 70 specimens collected primarily in Europe North America. The results our analyses support separation traditional ...
