Effects of S-3307(Uniconazole) application on amount to content of protein components and processing quality of wheat grain were studied in more rain and low light stress environment.The results showed that increase application of S-3307 significantly improved content of protein components by different extent.Rations of albumin and globulin to total protein increased significantly

about which B2 was the best

and rations of gliadin and glutein increased with the increase of concentration.Application of S-3307 significantly increased WGC and SDS

prolonged DDT and DST

and improved its WA

increased VV

and subsequently improved the processing quality of wheat grains.
