Abstract

Although the possibility that mechanical stimulation is a factor in the quantity of strengthening tissue in the stems of plants has been frequently suggested, few experiments have been designed to test this hypothesis. Although some work has been done on tensile strength of collenchyma (Ambronn 1881, Esau 1936, Curtis 1938), very little consideration has been directed to the study of the effect of mechanical stimulation on the structure and/or quantity of this tissue or any of the mechanical tissues of the plant. Venning (1949) reported that wind motion from an electric fan stimulated the development of collenchyma within the petioles of Apium graveolens L., but had no effect on the number of collenchyma bundles per petiole. He reported that stimulation by wind motion resulted in larger areas of collenchyma and in an increase in cell wall thickness of the collenchyma.
