The Effects of Growth Regulators on Agronomic Traits and Yield on Oilseed Rape
To explore the appropriate growth regulators in the production process of oilseed rape in Menyuan County,the oilseed rape variety'Haoyou 11'was used as the experimental material,and set up five plant growth regulator treatments(2%triasanol benzylaminopurine suspension,1%indole butyrate and triaconol milk powder,1%indole butyrate and induced analoin solution,0.01%brassinolide solution,0.4%triacontanyl purine solution)and one water control treatment.The agronomic traits,yield,and yield composition indexes of different treatments were compared.The results showed that all the plant growth regulators helped to increase the height of branching nodes,the number of effective pods per plant,the number of seeds per pod,thousand-seed weight,and yield of rapeseed.Considering all factors,it is believed that the use of 0.01%brassinolide solution at 3,000 times dilution and 0.4%triacontanyl purine solution at 500 times dilution resulted in the best agronomic traits and yield of rapeseed.It is recommended to vigorously promote and apply these treatments in Menyuan Autonomous County..
