Response of Maize Growth and Water-Photosynthesis Characteristic to Different Combination of Air Humidity with Soil Moisture
water and photosynthesis characteristic of maize under different combination of air humidity with soil moisture
the results showed the harm of soil water deficit exceeded that of air drought
water status and physiological activities were mainly decided by soil moisture. Short-term drought made photosynthetic rate decrease. For soil dry treatments
the main reason was nonstomatal limitation
but for air-dry-soil-wet treatment
stomatal limitation at first but nonstomatal limitation later. Dry matter continued to increase during the period of short-term drought.
