A Comparative Study of Leaf Structure as Modified by Three Environments Commonly Used to Grow Plants for Experimental Use.
Abstract
Bean (Phaseolus vulgaris L. cv. Black Valentine), radish (Raphanus sativus L. cv. Scarlet Globe) and morning-glory (Ipomoea purpurea L. cv. Heavenly Blue) plants were grown in three commonly employed environments (greenhouse, growth chamber and field) used for producing plants for experimental use. Leaves from these plants were examined under the light microscope and differences were found to occur in leaf thickness, internal organization and cuticular deposition, dependent upon the conditions under which the plants were grown. Leaves from plants grown under field conditions were generally thicker with greater cuticular deposition than leaves from the growth chamber or greenhouse-grown plants. Changes in internal organization appeared to be dependent upon a species-environment interaction, with leaves of growth-chamber bean plants more closely resembling those from field-grown plants, while leaves of radish plants grown in the growth chamber were quite different from those of field or greenhouse plants. Anatomy of morning-glory plants was less affected by environment than the other species tested. (Author)
