GRAIN α-AMYLASE ENZYME POTENTIAL AND GIBBERELLIC ACID SENSITIVITY OF NEARLY ISOGENIC TALL, SEMI-DWARF, AND DWARF WHITE WHEATS

α-Amylase enzyme potential and gibberellic acid (GA) sensitivity were compard in Norin 10/Brevor 14//7*Burt soft white wheat (Triticum aestivum L) lines that were nearly isogenic for eht, Rht1, Rht2, Rht1 + Rht2, and Rht3 genes. Grain was produced on plants grown in soil and nutrient solution media...

Description
Summary:α-Amylase enzyme potential and gibberellic acid (GA) sensitivity were compard in Norin 10/Brevor 14//7*Burt soft white wheat (Triticum aestivum L) lines that were nearly isogenic for eht, Rht1, Rht2, Rht1 + Rht2, and Rht3 genes. Grain was produced on plants grown in soil and nutrient solution media under controlled environments, germinated in water and GA, and analyzed for α-amylase enzyme activity. Presence of Rth1 and, particularly, Rht2 genes decreased enzyme potential and GA sensitivity, but effects were not additive and were much smaller than effects of Rht3. Norin 10/Brevor 14, however, appeared to have other genes for high αamylase activity and low GA sensitivity.
