Pollination Requirements for Tree and Small Fruits

In the flower, pollination is the transfer of pollen from the anther to the stigma. After pollination and fertilization, fruit set occurs. There are two types of pollination. Self-pollination occurs when the pollen is transferred from the anther to the stigma on the same flower, from another flower on the same plant, or from a flower on another plant of the same variety. Self-pollinated plants are said to be self-fruitful. Many plants cannot produce fruit from their own pollen and are considered self-unfruitful. These plants require cross-pollination for fruit set.

Iowa Community Tree Steward

The Iowa Community Tree Steward program (formerly know as the Master Community Tree Manager program) will be offered to residents of central and eastern Iowa in 1994. This educational program is sponsored by the Iowa Urban and Community Forestry Council, in cooperation with Iowa State University Extension, the Forestry Division of the Iowa Department of Natural Resources, and Trees Forever. The purpose of the program is to develop a network of highly motivated, well-trained volunteers to assist in the improvement and expansion of community tree resources in Iowa.
