Reproduction studies, particularly embryology, represent basic information of any plant. However, the current embryological is fragmentary for Kentucky bluegrass (Poa pratensis L.). Here, paraffin sections were used to examine cyto-embryological characteristics, including microsporogenesis, microgametogenesis, megasporogenesis, megagametogenesis, and apomixis, wild germplasm from Gannan (GN) Lo...

Kentucky bluegrass (Poa pratensis L.), a turf grass species that is hypertolerant of cadmium (Cd), potential phytoremediation material for soil polluted with Cd. However, the mechanism Cd phytotoxicity in unclear. Here, we compared phenotype, induction oxidative stress, and structural non-structural carbohydrate contents between Cd-tolerant genotype (‘Midnight’, M) Cd-sensitive (‘Rugby’, R). Th...
