Complete Kit of Pollenizing Tools
This shows all the apparatus required for the most elaborate series of experiments in cross-fertilization. The scapel is used sometimes to cut across unopened blossoms-for example, apple blossoms-in such a way as to remove the pollen bearing anthers all at once. Where the form of the flower does not permit this, the pincers are used to pluck out the stamens. The watch crystal is used to collect pollen, which is transferred to the stigma of another flower with with the finger tip or with a camel's hair brush. The other implements are required exceptionally to manipulate a flower of peculiar form. The magnifying glasses are needed only with very small flowers. The use of the paper bags is illustrated in an earlier photo. The cardboard labels are to record the experiment.
