MOTOR NEURON DISEASES. Amyotrophic Lateral Sclerosis (ALS) is a fatal degenerative disorder of upper and lower motor neurons. Lower motor neuron loss causes muscle weakness, atrophy, and fasciculations; upper motor neuron involvement causes spasticity, clonus, hyperactive tendon reflexes, and Babinski signs.OTOR NEURON DISEASES.

Methods of Propagation. I have found that the hazelnut tree is clearly out of the ordinary in a horticultural sense. It has a unique and wonderful side to it. The way in which it achieves pollination in the winter and completion of nut set in the spring, is truly interesting.ue to my overwhelming interest in the tasty Corylus nut, you are invited on a journey to learn about the production and propagation of Hazelnut and the trees that produce them. Introduction. Hazelnuts come from the family Corihave. There are about 18 different species of Corylus.
This method is not recommended for lilacs. In many instances, lilacs are grafted. Grafting is much more successful than propagation by cuttings. Another method of propagation that is useful for lilacs that are not grafted is to dig suckers from around the base of the plant and replant them. These suckers are sprouts that developed from the roots and have formed their own roots. This is perhaps the easiest way for most homeowners to propagate lilacs.
