Tissue culture methods for plant regeneration have been developed for Lasiurus scindicus, Sorghum halepense and Urochloa panicoides using basal portion of young inflorescence as new and a potential source(s) of explants. Highly embryogenic cultures were initiated on Murashige and Skoog’s (MS) medium supplemented with various concentrations of 2,4-dichlorophenoxyacetic acid (2-4,D). The regenera...

Original meiotic or mitotic chromosome counts are presented for 17 species in 12 families of angiosperms from Iran. Chromosome counts for Amberboa nana, n=16 (Asteraceae) and Camelina rumelica subsp. transcapica, n=13 (Brassicaceae) are repoted for the first time. Chromosome numbers for six species including: Rhagadiolus stellatus (n=5), Campanula raponcoloides (n=34), Campanula trachelium (n=1...

Weed behaviour in crop fields has been extensively studied; nevertheless, limited knowledge is available for particular cropping systems, such as no-till systems. Improving weed management under conditions requires an understanding of the interaction between residues and seedling emergence process. This study aimed to evaluate influence maize wheat residues, applied three different quantities (...
