Morphological aspects about germination of Vulpia myuros (L.) C.C. Gmel. caryopsis.
Caryopsis harvested in 2014 from a population of Vulpia myuros, invasive in a rape seed crop, were tested for germination over 3 years and a half after harvesting (2015-2018). The germination tests were done on paper moistened with distillate water in Petri dishes, in several variants with Vulpia caryopsis and seeds of different species - Triticum durum, Brassica napus, Helianthus annuus. Viability of the seeds of the Vulpia population, stored under laboratory conditions, was preserved during all this time. The germination of the Vulpia caryopsis was simulated in the presence of germinated seeds of the other species. Germinated caryopsis of Vulpia myuros showed a hairy coleorhiza which allowed high adherence of the seedling to the soil surfaces.
