Seed characteristics of smutgrass (Sporobolus poiretii)


, : Seed characteristics of smutgrass (Sporobolus poiretii). Proceedings, Soil and Crop Science Society of Florida 1973 (Volume 32): 53-54

The seed production potential, germination patterns and life cycle characteristics of S. poiretii were investigated in order to predict the duration of control in pasture and rangeland. S. poiretii shows the seed characteristics of a very successful weed. The mean of 16 inflorescence samples indicated production of 45 824 seeds/plant at the time of sampling in spring; there were 29-32 seed heads/plant with up to 1432 seed/mature panicle.

Excitatory synaptic transmission between pyramidal cells and fast-spiking (FS) interneurons of layer V of the motor cortex was investigated in acute slices by using paired recordings at 30 degrees C combined with morphological analysis. The presyn...
