Abstract

Stomatal resistance was measured daily with a stomatal diffusion porometer during a 4-week period in leaves of bean (Phaseolus vulgaris L., var. Bush Blue Lake) and barley (Hordeum vulgare L., var. Liberty) plants having roots equally split between two differentially salinized nutrient solutions. The stomatal conductance (reciprocal of stomatal resistance) of plants with half their roots in saline solutions was intermediate between the stomatal conductances of plants grown in nonsaline solutions and those grown in saline solutions.

摘要

在 4 周的时间里，用气孔扩散仪每天测量豆类（菜豆，布什蓝湖品种）和大麦（普通大麦，自由品种）叶片的气孔阻力，这些植物的根系平均分布在两种不同盐化的营养液中。根系一半在盐溶液中的植物的气孔导度（气孔阻力的倒数）介于在非盐溶液和盐溶液中生长的植物的气孔导度之间。
