Three varieties of winter wheat–“Sui-yuan”, “Sino-soviet 68”, and “Kingling Univ. 2905” – were used as the experimental materials. Seeds were soaked in various micro-element solutions for 14 hours in the following concentrations: CuSO4·5H2O 0.05 gm/l, MnSO4·nH2O 0.15 gm/l, ZnSO4·7H2O 0.25 gm/l, FeSO4·7H2O 0.25 gm/l, H3BO3 0.25 gm/l, and MoO3·H2O 0.05 gm/1. Distilled water was used as control. Then put the seeds in a refrigerator at 0–3℃ for vernalization, the first two varieties were vernalized for 35, 40, 45, and 50 days and the last one was vernalized for 15, 20, 25 and 30 days respectively. After vernalization the seeds were sown in the field or pot. The growth and development were observed in different growth period.
The results showed that copper, zinc, molybdenum and boron stimulated not only the early growth but also accelerated the development of wheat. For example the experiment in 1956, “Sui-yuan” variety after 45 days vernalization, the date of heading was 9 days early by the treatment of zinc, 7 days early by the treatments of molybdenum and boron, 2 days early by the treatment of copper. However, manganese and iron stimulated only the early growth but on effect on the development. Same results were obtained in the experiments of 1947, it showed that “Sui-yuan” variety vernalized for 40 days produced heads on July I to 4 by the treatments of copper, boron, zinc and molybdenum, but no head was observed in the plants which the seeds were previously treated with manganese and iron.
