Activities of leaf and spike carbohydratemetabolic and antioxidant enzymes are linked with yield performance in three spring wheat genotypes grown under wellwatered and drought conditions

To improve our understanding about the physiological mechanism of grain yield reduction at anthesis, three spring wheat genotypes [L1 (advanced line), L2 (Vorobey) and L3 (Punjab-11)] having contrasting yield potential under drought in field were investigated under controlled greenhouse conditions, drought stress was imposed at anthesis stage by withholding irrigation until all plant available water was depleted, while wellwatered control plants were kept at 95% pot water holding capacity. |
