Description
The measurement of morphological and physiological indices of Phalaris arundinacea to drying and irrigation treatments and in natural field conditions (ck) were conducted in tillering stage and stem elongation stage. Results show that plants in the drying treatment, compared with plants in the irrigation treatment and control, that their single plant leaf area, plant height, chlorophyll content, intensity of photosynthesis, stomatal area and plant yields were decreased, but the intensity of respiration increased. Through statistic analysis, none of those indices, except stomatal area, were significantly different. It indicates that the species of Phalaris arundinacea is strongly drought resistant and could ensure stable yields under drought conditions. It provides a promising hay crop for semi-arid regions.
