Preserving Biodiversity in Marginal Rural Areas:Assessment of Morphological and Genetic Variabilityof a Sicilian Common Bean Germplasm Collection
2020
The historical cultivation of common bean (Phaseolus vulgaris L.) has resulted in the development of local populations/cultivars in restricted Italian rural areas. Many common bean landraces, still cultivated in small mountain areas from Sicily, have become outdated and endangered due to the commercial varieties spreading. These accessions are poorly known but often represent a genetic heritage to be preserved and enhanced. The ex situ conservation of fifty-seven Sicilian common bean landraces was carried out at the &ldquo
The Seedbank database of the Hortus Botanicus Panormitanus
2012
A database for the management of the Seedbank of the Palermo’s Botanical Garden has been set up. Its structure and functioning are illustrated. Since November 2010 about 2000 records relating to 460 taxa have been inputted and are accesible via web. Links with other seedbank databases and with the database of the Herbarium Mediterraneum Panormitanum and of the Palermo’s Botanical Garden are explained.
Soil weed seedbank composition and structure in a long-term nutrient management experiment
2016
EAGESTAD; Weed communities can be influenced by nutrient availability, nutrient form (e.g. ammonium vs. nitrate), amendment timing, amendment type, and by immigration of seeds during amendment applications. New York ranks third in the United States in the number of dairy cows and thus dairy manure applications are prevalent throughout the state. The objective of this work was to compare the effect of dairy manure and inorganic fertilizer on soil weed seedbank composition and structure in a long-term nutrient management experiment. The field experiment was initiated in 2001 at the Cornell Musgrave Research Farm in Aurora, NY and compared ten treatments in a corn-alfalfa rotation using a rand…
Legacy Effects of Contrasting Long-Term Integrated Weed Management Systems
2022
To reduce reliance on herbicides and maintain crop productivity, integrated weed management (IWM) seeks to optimize synergies between diverse sets of weed management practices combined at the cropping system scale. Nevertheless, data on weed community response to the long-term implementation of IWM practices remain scare. Here, we assessed the effects of four IWM systems with contrasting objectives and practices (S2: transition from superficial tillage to conservation agriculture; S3: no-mechanical weeding; S4: mixed mechanical and chemical weeding; S5: herbicide-free; all with 6 year rotations) compared to a conventional reference (S1: herbicide-based with systematic plowing and a 3 year r…
