3. 2. Winter wheat exudates : Improving wheats resilience to drought

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Freja Haverland; [2024]
   Keywords : drought; PGPR; exudates; agriculture; food security;

   Abstract : Wheat (Triticum aestivum) is a crop that dominates the diets of about 35% of the world's human population. But wheat yields can be severely affected by drought. Therefore, in this experiment, root exudation of winter wheat was compared to find out how exudation changes during drought stress. READ MORE
