Forexample, in some strawberries the stamens are absent oruseless; that is, they bear no good pollen. In such casesthe grower must see to it that near by are strawberry plantsthat bear stamens in order that these plants which do not Fig. 35. Squash Blossoms. 48 AGRICULTURE FOR BEGINNERS bear pollen may become pollinated, that is may have pollencarried to them. After the stigma has been supplied withpollen, a single pollen grain sends a threadlike sprout downthrough the stigma into the ovary. This process if success-fully completed is called fertilisation. EXERCISE Examine several flowers and identify the parts named in the lastchapter. Try in proper season to find the pollen in the maple, willow,alder, and pine, wheat, cotton, and morning-glory. How fast does the ovary of the apple blossom enlarge ? Measureone and watch it closely from day to day. Can you find any plantsthat have their stamens and ovaries on separate individuals? SECTION XV —POLLINATION Nature uses several interesting ways to secure pollentransportation. In the corn, willow, and pine, the pollen ispicked up by the wind and carried away. Much of it is lost,but some reaches the stigmas or receptive parts of other corn,willow, or pine flowers. This is a very wasteful metho
