摘要: Abstract Field emergence is crucial in determining the yield and quality of French beans for canning industry. The aim this study was to analyze variation bean results, particularly determine relative influence seed characteristics sowing conditions. During 2004 2005, at two sites France (North: 50.1°N, 3°E; West: 47.3°N, 0.3°W), field experiments were carried out order obtain information on under a range Four lots cultivar Booster with differing germination seedling growth parameters determined laboratory conditions sown. These results also used compare observed simulations crop model. Subsequently, effects greater diversity three main cropping areas simulated using In experiment, rates always high (80–100%). contrast, final varied from 56 90%, lasting 9 28 days. differences large between situations but small lots. Emergence mainly delayed by low temperatures (
