| Popis: | The article examines cotyledonous bacterial blight – a possible causes of the decrease in seed sowing quality of leguminous crops. The article presents the hypothesis that there is another cause for the development of cotyledonous necroses, regardless of species, variety, and crop’s cultivation area. The secondary (rain) moistening of mature seeds leads to the development of cotyledonous necroses and a decrease in seed germination of soybean, white bean, chickpea, white lupin, and blue lupin due to the subsequent necrotization of over-moistened areas of cotyledon tissues. The secondary moistening of mature seeds can lead to the development of cotyledon necrosis and a decrease in germination of soybean seeds, white beans, chickpeas, white lupin and blue lupin due to subsequent necrotization of waterlogged areas of cotyledon tissues. The symptoms of cotyledon necrosis development during secondary moistening of mature seeds and cotyledonous bacterial blights are almost identical in all leguminous crops. Bacterial pathogens of various species and families are isolated on the dead areas of cotyledons. This fact can be explained by the repeated saprophytic infection of cotyledon sites. |
