DETERMINATION OF STOMATAL NUMBERS, STOMATAL LENGTHS, AND DRY WEIGHT INCREMENTS OF DETACHED BROMEGRASS LEAVES

Abstract

A field technique based on dry-matter accumulation in detached leaves was tested with bromegrass (Bromus inermis Leyss.) for use as an indicator of differences in net photosynthetic rates. It was suggested that the technique could not be used in a breeding program.A second study of differences in stomatal number and length suggested that interplant differences could be detected with some degree of repeatability by using a silicon impression technique.
