-Two divisions of the nervous system: central and peripheral. -Central nervous system consists of the brain and spinal cord. -Peripheral nervous system consists of the sense organs (eyes, ears, taste buds, olfactory receptors, touch receptors) and the nerves which connect the spinal cord with the rest of the body.
Ripening Temperatures. After the chill period, pears ripen best between 65 and 75 degrees F. Oregon State University Extension indicates that Bartlett pears take only four to five days to ripen, while Anjou takes up to 10 days. Both Bosc and Comice pears need between five and seven days to ripen. The days indicated for ripening are a guide but not law. Pears ripen faster when they get a longer chill period and take longer if the chill period was cut short. The best way to tell is to press your finger into the flesh near the stem.
Get the soil right, Stella Otto advises, then get the trees.. Pears are usually sold as one-year-old, unbranched whips.. Dwarf varieties begin to bear fruit three to five years after the whip is planted; semidwarfs produce a full harvest in five to seven years.
