Abstract

The trials of drought-resistant wheat varieties Jinmai 33 and drought sensitive wheat varieties Jimai, 38 in wheat leaves under drought conditions spraying 6-BA and KT on wheat grain quality Materials Research, located four treatments each wheat flowering normal watering (CK1), a flowering the arid spray (CK2), 6-BA flowering drought foliar spray (10 ^{-5 mol · L ^{-1 ) and flowering drought the foliar spray KT (10 ^{-5 mol · L ^{-1 ), after the wheat harvest of wheat by the International Association of Cereal Chemistry Standards and the National Standards made comprehensive quality testing, experimental detection flowering stage of wheat under water stress conditions foliar spraying 6-BA and KT, compared with CK2 product quality and production ability to maintain and improve. The drought treatment process soil relative water content gradually decreased (76% -40%). Experimental results prove drought Jinmai 33, and Jimai 38 protein content of whole wheat flour and flour wet gluten content, sedimentation value lower than CK1, drought sprayed 6-BA significantly than the CK2 protein content of the whole wheat flour increased ,6-BA Jimai - 38 role similar to the role of Jinmai -33; drought sprayed 6-BA Ji wheat 38 flour wet gluten content than CK2 flour increased significantly; drought sprayed 6-BA and KT flour than CK2 flour sedimentation value rose 6 the-BA role than the role of KT ,6-BA and KT superior role of of Jimai -38 to role of Jinmai -33; the drought Jinmai 33 α-amylase activity of flour than CK1 falls, drought spray 6-BA and KT α-amylase activity of wheat flour than CK2 rise of ,6-BA role than the role of KT; drought fatty acid value Jinmai 33 and 38 Jimai flour than CK1 rise, drought spray 6 - ,6-BA fatty acid value of the BA and KT wheat flour, lower than CK2 is greater than the role of KT ,6-BA and KT on role of Jimai -38 and similar to the role of Jinmai -33; spraying 6-BA and KT flour fat content between CK1 and CK2 the normal content ,6-BA and KT Jimai -38 role similar role of Jinmai 33; 33 Jin wheat the four treatments flour ash content difference small, Ji wheat 38 the four treatments flour ash content is also very small difference, and have reached the national special first-class powder standard ,6-BA and KT on Jimai -38 role similar role of Jinmai 33; the drought Jinmai 33 and of 38 flour Jimai Ca ^{2 content lower than CK1 drought sprayed 6-BA and KT wheat flour Ca ^{, 2 content than CK2 rise, KT's role greater than 6-BA ,6-BA and KT on Jimai -38 role similar to the role of the Jinmai 33. This test also proved under water stress after spraying 6-BA and KT ,6-BA wheat grain weight and wheat production role is greater than the role of KT ,6-BA and KT Jimai -38 superior to Jinmai -33 role. Short, spraying 6-BA and KT wheat Yang flowering drought conditions conducive to Drought Resistance and Yield, conducive to the shelf life increased quality, suitable for use in North China and Northwest China as an emergency drought measures.}}}}}}
