| Abstract: | Field spreading of either TPK(potassium hydrogen 1-triacontyl phosphate, with the concentration of 0.01 mg/L) or TA(triacontanol, with the concentration of 0.5mg/L) could obviously improve the yield traits in autotetraploid barley, and their degrees of improvement were almost the same. In result, the length of spike neck was exserted from 2.4cm to 3.7cm, and the incidence of spike wrapping was reduced. At the same time, the spike weight from 1.145g to 1.338g, the seed setting percentage from 75.0% to 79.5%, and 1000-grain weight from 43.638g to 50.031g were increased respectively. |
