The periodicity of germination in some grass species

A STUDY ON SEED DORMANCY AND GERMINATION IN TEN SPECIES OF GRASS WEEDS

       Seed dormancy has an important role in resistance and survival mechanisms of plants. Finding of some information about the range of primary dormancy and effective factors in dormancy breaking and optimal conditions of seed germination are necessary for weed control and other research purposes.  In this research, the seeds of 10 species of grass weeds in Tehran province fields (Echinocloa...

Identification of some grass-associated species of Bipolaris, Curvularia and Exserohilum in selected regions of Iran

Infected tissues of roots and leaves of various grasses as well as soil around their rhizosphere were sampled from Fars, Golestan, Isfahan, Khorasan Shomali, Khorasan Razavi, Mazandaran and Semnan provinces (Iran). Based on morphological characteristics and available keys, four species of Bipolaris including B. austreliensis, B. indica, B. micropus and B. spicifera, four species of Curvularia i...
