| Abstract: |
| The objective of this study is to investigate the effects of progressive drought and direct drought on root growth of maize seedlings subjected to well watered, moderate water stress and severe water stress, respectively, with hybrid maize Gaoyou 115. The results indicated that moderate water stress (55% FC) was the most advantages for root growth in conditions of progressive drought, while well watered (75% FC) was the most favor in conditions of direct drought. When the root system was sorted into fine roots (0.05 mm |
