【Abstract】 The experiment in wheat seeds treated with pentefezol indicated that the dosage of 100mg/kg and 200mg/kg can slightly inhibit the seedling emergence and growth, but promote the secondary roots growth and also had little effect on the length of basic node, but the stem diameter and content of dry matter weight obviously increased. The ability in resistance to lodging and the number of panicle per square meter was increased, but number of grain per panicle and 1000-seed weight had little variation. Finally, 1.5%-6.8% of wheat yield was increased.更多还原
