Estimating the cardinal temperatures of germination for Ipomoea hederaceae and Cleome viscosa at constant and alternating temperature conditions
Extended abstract: Introduction: Reports indicate the invasion of two species of Ivy-leaved morning-glory (Ipomoea hederaceae Jacq) and Asian spider flower (Cleome viscosa L.) to summer crops fields such as soybeans in Golestan province. Considering the importance of knowing the cardinal temperatures of germination in the models for predicting the presence of weeds and consequently designing c...
متن کاملControl of Flaxleaf Fleabane (Conyza bonariensis) in Wheat and Sorghum
Flaxleaf fleabane is a difficult-to-control weed in dryland minimum tillage farming systems in the northeast grains region of Australia. Experiments were conducted between 2003 and 2005 to identify effective control strategies on flaxleaf fleabane in wheat and sorghum. A preplant application of chlorsulfuron at 15 g ai/ha in wheat controlled flaxleaf fleabane $ 90%. The efficacy of early postem...

calcium oxalate crystals in Conyza canadensis (l.) cronq. and Conyza bonariensis (l.) cronq. (Asteraceae: Astereae)
Calcium oxalate crystals (CaOx) are found in most organs and tissues of many plant species. In this study the morphology and distribution of CaOx crystals in Conyza canadensis (L.) Cronq. and Conyza bonariensis (L.) Cronq. belonging to Asteraceae were investigated. CaOx crystals display a similar distribution in organs and tissues of C. canadensis and C. bonariensis. For the identification of C...
